Fergusobia porosae n. sp. is morphologically characterized by the combination of an arcuate to C-shaped parthenogenetic female with a small conoid tail, an almost straight to arcuate infective female with an hemispherical tail tip, and males that are almost straight to barely J-shaped with angular spicules and short peloderan bursa. Morphologically, F. porosae n. sp. is similar to F. microcarpae n. sp. and F. fisheri. From phylogenetic analyses based on sequences of D 2 /D 3 and COI, it is genetically close to Fergusobia spp. collected from flat leaf galls on E. siderophloia (V���s 25���28), Eucalyptus spp. (V���s 29, 348), E. microcarpa (V 67), and F. f i s h e r i from E. leucoxylon It is also close to F. eugenioidae from flower bud galls on E. eugenioides (V 349), and Fergusobia spp. from axial bud galls on E. porosa (V 69). The arcuate to open C-shaped parthenogenetic females of F. porosae n. sp. are similar to those of F. jambophila and F. fisheri, but different to those of F. brittenae, F. i n d i c a, F. microcarpae n. sp., and F. ptychocarpae (more curved); and from F. leucadendra and F. r i l ey i (almost straight to arcuate). In length (265���357 ��m), F. porosae n. sp. is smaller than F. magna (418���780 ��m) and F. tumifaciens (415 ��m); and larger than F. cajuputiae (221���273 ��m) and F. fasciculosae (237���285 ��m). The stylet (9���9.5 ��m) of parthenogenetic females of F. p o ro s a e n. sp. is shorter than in F. camaldulensae (11���13 ��m), and longer than in F. brevicauda (8���8.5 ��m), F. curriei (5���8 ��m), F. juliae (5���7 ��m), and F. morrisae (7���8 ��m). In having large to enormous oesophageal glands (b��� 1.7���3.3), it is similar to most described species, but differs from F. jambophila which has smaller glands and from F. quinquenerviae which has enormous glands with a reflex or extra lobe at the posterior end. The shape of the body behind the vulva (arcuate, with a small volume and a bluntly rounded tip) differs from that in F. philippinensis (ventral edge from vulva to tail tip less curved); and F. pohutukawa (narrow, conoid tip). The length of the tail separates F. p o ro s a e n. sp. (9���20 ��m) and F. eugenioidae (18���27 ��m). The hemizonid is 2���4 annules anterior to the secretory/excretory pore in F. p o ro s a e n. sp., but immediately anterior in F. eugenioidae, and 7���8 annules anterior in F. fisheri. In parthenogenetic females of F. p o ro s a e n. sp., the anus opens into a depression in the cuticle which is not seen in F. dealbatae or F. nervosa. Infective females of F. p o ro s a e n. sp. are almost straight to arcuate in shape, which is different to F. magna, F. brittenae, F. curriei, F. fasciculosae, F. microcarpae n. sp. (which are arcuate to open C- shape); F. eugenioidae, F. juliae, F. morrisae, and F ptychocarpae (which are strongly curved in posterior region); and F. r i l e y i (which are almost straight). Fergusobia porosae n. sp. infective females are shorter (277���300 ��m) than those of F. magna (537���633 ��m), F. brevicauda (330���410 ��m), F. brittenae (375���550 ��m), F. curriei (417���489 ��m), F. dealbatae (307���347 ��m), F. eugenioidae (438 ��m), F. juliae (396���550 ��m), F. morrisae (322���395 ��m), F. ptychocarpae (387���471 ��m), and F. r i l e y i (378���432 ��m). The shape of the body behind the vulva (straight, with almost hemispherical tip), differs from F. nervosae and F. viridiflorae (more curved, with bluntly rounded tail tips), F. camaldulensae (arcuate with hemispherical tip), and F. philippinensis (truncate tip). In F. porosae n. sp., the ratio c (15.3���23.4) is larger than in F. leucadendrae (9.1���11.7). Infective females of F. p o ro s a e n. sp. are morphologically similar to those of F. fisheri, but are mostly straighter and with a more narrowly rounded tail tip. They are also similar to F. quinquenervia and F. cajuputiae, but mostly have smaller oesophageal glands (b��� 3.3���4 vs 2.2���3.2 and 2.2���3.1). In addition, F. p o ro s a e n. sp. differs from F. quinquenerviae in having a shorter tail (13���20 ��m vs 20���29 ��m) and a larger ratio c (15���23 vs 11���15). The shape of males of F. porosae n. sp. (almost straight to arcuate to barely J-shape) is similar to that of many species of Fergusobia. Male F. p o ro s a e (270���326 ��m long), are shorter than male F. magna (446���588 ��m), F. brevicauda (330���420 ��m), F. camaldulensae (383���451), F. curriei (370���492 ��m), F. eugenioidae (341���420 ��m), F. morrisae (347���413 ��m), F. pohutukawa (398���469 ��m), F. ptychocarpae (495���525 ��m), F. rileyi (378���508 ��m), and F. tumifaciens (415 ��m). Tail shape (arcuate with bluntly rounded tip) differs from that of F. philippinensis (truncate). The c ratio (7.9���12.6) is smaller than in F. quinquenerviae (12.9���17.8). Spicule length (11���15.5 ��m) is smaller than in F. brittenae (19���25 ��m), F. dealbatae (18���22 ��m), F. fisheri (16���20 ��m), F. juliae (20���27 ��m), F. nervosae (16���19 ��m), and F. viridiflorae (18���20 ��m). The bursa of F. p o ro s a e n. sp. is short and differs from that of F. cajuputiae and F. jambophila (in which it is longer). Males of F. p o ro s a e n. sp. have more lightly sclerotised spicules than do those of F. leucadendrae. Males of F. p o ro s a e n. sp. have heavier-looking spicules than F. fasciculosae, but the tail has a slimmer shape. Etymology.

Fergusobia delegatensae n. sp. is morphologically characterized by the combination of an open C-shaped parthenogenetic female with a broadly conoid tail, an infective female of variable shape with an hemispherical tail tip, and male of open C-shape with a bursa that arises 40���70 % along the length of the body and terminates just posterior to the cloaca. In form, the parthenogenetic female of F. delegatensae n. sp. is closest to those of F. eugenioidae, F. fasciculosae, F. fisheri, F. juliae, F. microcarpae, and F. porosae. The infective female is closest to those of F. brittenae, F. cosmophyllae n. sp., F. diversifoliae n. sp., and F. fasciculosae. The male is closest to those of F. diversifoliae n. sp. From phylogenetic analyses based on sequences of D 2 /D 3 and COI, F. delegatensae n. sp. is genetically close to Fergusobia spp. isolated from multilocular shoot bud galls on E. amygdalina, E. diversifoliae (F. diversifoliae n. sp.), and E. racemosa, and from flower bud galls on E. obliqua. In shape (open C), the parthenogenetic female of F. delegatensae n. sp. differs from those of F. fasciculosae (arcuate); F. brittenae, F. cosmophyllae n. sp., F. floribundae n. sp., F. i n d i c a and F. minimus n. sp. (C-shape); and F. rileyi (almost straight to arcuate). It is longer (345���527 ��m) than F. cajuputiae (221���273 ��m), F. fasciculosae (237���285 ��m), F. fisheri (228���305 ��m), F. jambophila (195���300 ��m), F. leucadendrae (205���303 ��m), F. morrisae (262���347 ��m), F. nervosae (245���309 ��m), F. philippinensis (229���310 ��m), F. quinquenerviae (224���324 ��m), and F. viridiflorae (259���328 ��m). The stylet (8���10 ��m) is longer in this parthenogenetic female than in F. floribundae n. sp. (6���7 ��m) and F. juliae (5���7 ��m); and shorter than in F. camaldulensae (11���13 ��m), F. indica (12���15 ��m), and F. rileyi (10���13 ��m). In having large to enormous pharyngeal glands (b��� 1.8���2), it is similar to most described species, but differs from F. brevicauda, F. magna, and F. tumifaciens which have smaller glands. The position of the vulva (85���87 %) is more posterior than in F. curriei (78���84 %). The shape of the body behind the vulva of F. delegatensae n. sp. (conoid, arcuate, with bluntly rounded tip) differs from that of F. brevicauda, F. cajuputiae, and F. leucadendrae (arcuate with broadly rounded tip), and from F. dealbata, F. magna, F. morrisae, F. philippinensis, F. pimpamensis n. sp., and F. ptychocarpae (more slender, arcuate or straight tails). Tail length (14���18 ��m) is shorter than in F. brittenae (23���37 ��m) and F. pimpamensis n. sp. (20���41 ��m), and F. pohutukawa (19���35 ��m). Ratio a (8.4���10.3) in F. delegatensae n. sp. is larger than in F. pohutukawa (4.4���8.2) and F. tumifaciens (7���8). Ratio c in F. delegatensae n. sp. (21.6���27.1) is larger than F. camaldulensae (9���17.9), F. curriei (9.6���14.9), F. eugenioidae (13���19), F. juliae (12.5���19.9), and F. tumifaciens (10���11). The position of the hemizonid (5 annules anterior to the secretory/excretory pore) separates F. delegatensae n. sp. from F. microcarpae (2���3 annules anterior), F. porosae (2���3 annules anterior), and F. diversifoliae n. sp. (8 annules anterior). The infective female of F. delegatensae n. sp. is arcuate in shape, differing from F. brittenae, F. curriei and F. magna (open C); F. fisheri (barely J); from F. eugenioidae, F. juliae, F. morrisae, and F. ptychocarpae (strongly curved in posterior region); and F. r i l e y i (almost straight). In length (375���452 ��m) it is smaller than F. magna (537��� 633 ��m); and larger than F. cajuputiae (239���309 ��m), F. dealbatae (307���347 ��m), F. fasciculosae (268���332 ��m), F. leucadendrae (227���291 ��m), F. p oro s a e (277���300 ��m), and F. quinquenerviae (259���325 ��m). Ratio a (10.5���12) of the infective female of F. delegatensae n. sp. is larger than in F. brevicauda (6.5 ���9.0) and F. cosmophyllae n. sp. (4���6.8). The vulva is more posterior (83���90 %) than in F. philippinensis (70���82 %). The stylet is longer (8���11 ��m) n. sp. than in F. microcarpae (6���7 ��m) and F. minimus n. sp. (4���5 ��m). The shape of the body behind the vulva in F. delegatensae n. sp. is straight with a hemispherical tip; differing from that of F. microcarpae, F. p o ro s a e, and F. quinquenerviae (straight with broadly rounded tips); F. philippinensis (with a truncate tip); F. nervosae and F. viridiflorae (arcuate with bluntly rounded tail tips); and F. floribundae n. sp. (curved, with hemispherical tips). F. delegatensae n. sp. is separated from F. pimpamensis n. sp. by having an off-set head; and from F. camaldulensae by lacking a peaked circum-oral area. The male of F. delegatensae n. sp. is arcuate to C-shaped, and differs from F. brittenae, F. curriei, F. juliae, and F. ptychocarpae (J-shape), F. eugenioidae n. sp. and F. tumifaciens (just J-shape); F. pohutukawa and F. rileyi (almost straight to arcuate); and F. porosae and F. jambophila (almost straight). In length (350���518 ��m), it is larger than F. fasciculosae (274���336 ��m), F. nervosae (277���312 ��m), F. p o ro s a e (270���326 ��m), and F. quinquenerviae (256���329 ��m). The arcuate, conoid shape of the tail differs from that of F. rileyi and F. viridiflorae (more slender, arcuate to straight), and F. philippinensis (arcuate with a truncate tip). The spicule is shorter (18���23.5 ��m) than that of F. magna (30���37 ��m); and longer than that of F. cosmophyllae n. sp. (12���15 ��m) and F. leucadendrae (14���17 ��m). In having an angular shape, the spicule differs from that of F. r i l e y i, F. pimpamensis n. sp. and F. jambophila, where it is arcuate. The bursa of F. delegatensae n. sp. ends just posterior to the cloaca, separating it from F. cajuputiae, F. camaldulensae, F. dealbatae, F. diversifoliae n. sp., F. fisheri, F. floribundae n. sp., F. microcarpae, F. minimus n. sp., and F. morrisae, in which it extends to or around the tail tip.

Inconspicuous muscles associated with cloaca. Tail more or less ventrally curved; length ~ 1���2.5 times diameter at cloaca; tip bluntly rounded. Diagnosis and relationships. Fergusobia minimus n. sp. is morphologically characterized by the combination of a C-shaped parthenogenetic female with a conoid tail, an open C-shaped infective female with a hemispherical tail tip, and arcuate to open C-shaped males with angular spicules and short, smooth, peloderan bursa. Morphologically, parthenogenetic females are most similar to those of F. brittenae, F. cosmophyllae, F. diversifoliae, F. floribundae n. sp., F. morrisae, and F. ptychocarpae. From phylogenetic analyses based on sequences of D 2 /D 3 and COI, F. minimus n. sp. is genetically similar to F. brittenae. In having a C-shape, the parthenogenetic female of F. minimus n. sp. differs from F. rileyi (almost straight to arcuate); and from F. brevicauda, F. curriei, F. delegatensae, F. fasciculosae, F. fisheri, F. nervosae, and F. viridiflorae (open C-shape). In length (303���421 ��m), it is shorter than the parthenogenetic female of F. i n d i c a (525���626 ��m) and F. magna (418���780 ��m); and longer than F. cajuputiae (221���273 ��m), F. jambophila (195���300 ��m), F. leucadendrae (205���303 ��m), and F. philippinensis (229���310 ��m). The cephalic region of F. minimus n. sp. is not retracted when heat killed, as occurs commonly in F. floribundae n. sp. and F. pimpamensis n. sp. The circum-oral area in the parthenogenetic female of F. minimus n. sp. is flat, differing from F. camaldulensae, F. eugenioidae, F. morrisae, and F. pohutukawa, in which it is raised. The stylet (4���8 ��m) is shorter than in F. camaldulensae (11���13 ��m) and F. dealbatae (9���10 ��m). The shape of the body posterior to the vulva (slender, arcuate, with bluntly rounded tip) differs from that of F. p o ro s a e (shorter); and from F. juliae, F. microcarpae, F. quinquenerviae, and F. tumifaciens (with more broadly rounded tips). The stylet length is mostly shorter (4���8 ��m, mean 6 ��m) than in F. brittenae (8���11 ��m, mean 9 ��m) and F. ptychocarpae (8���13 ��m, mean 10 ��m). The stylet length (4���8 ��m) is also mostly shorter than in F. cosmophyllae n. sp. (8���9 ��m) and the secretory/excretory pore is more anterior (55���116 ��m vs 158���221 ��m from the anterior end). It is also mostly shorter than in F. diversifoliae n. sp. (stylet 8���11 ��m, mean 9 ��m), and the latter does not have the large cells surrounding the duct to the excretory pore that occur in F. minimus n. sp. The infective female of F. minimus n. sp. differs in shape (open C) from that of F. eugenioidae, F. juliae, F. morrisae, and F ptychocarpae (strongly curved in posterior region); from F. camaldulensae (arcuate); and from F. rileyi (almost straight). In length (419���458 ��m), the infective female is smaller than in F. magna (537���633 ��m) and larger than in F. brevicauda (350���410 ��m), F. cajuputiae (239���309 ��m), F. dealbatae (307���347 ��m), F. fasciculosae (268���332 ��m), F. leucadendrae (227���291 ��m), F. microcarpae (302���341 ��m), F. p oro s a e (277���300 ��m), F. quinquenerviae (259���325 ��m), and F. viridiflorae (321 ��m). The ratio a (10���12) n. sp. is larger than in F. cosmophyllae n. sp. (4���7). The stylet length (4���5 ��m) is shorter than F. curriei (7���9 ��m), F. delegatensae (8���11 ��m), F. diversifoliae (9���11 ��m) and F. pimpamensis n. sp. (6���10 ��m). Shape of the body posterior to the vulva (straight, with hemispherical tip) differs from that of F. fisheri and F. nervosae (conoid, with broadly rounded tips), and from F. philippinensis (truncate tip). The anterior fusiform part of the digestive tract is broader (length ~ 2 times diameter) than F. floribundae (length 3���4 times diameter). Fergusobia brittenae has a more posterior vulva (80���82 %) than F. minimus n. sp. (72���77 %). The male shape of F. minimus n. sp. (arcuate to C-shaped) differs from F. brittenae, F. curriei, F. juliae, and F. ptychocarpae (J-shaped); from F. tumifaciens (barely J-shaped); and from F. rileyi (straighter shape). The male body is longer (368���502 ��m), than F. cajuputiae (286���364 ��m), F. fasciculosae (274���336 ��m), F. jambophila (200���390 ��m), F. nervosae (277���312 ��m), F. p o ro s a e (270���326 ��m), and F. quinquenerviae (256���329 ��m). The stylet (4���7 ��m) is shorter than that of F. dealbatae (9 ��m), F. diversifoliae (9���11 ��m), F. eugenioidae (9���11 ��m) and F. f i s h e r i (8���11 ��m). The tail shape (arcuate, with a bluntly rounded tip) differs from that of the male of F. magna (more slender); and F. philippinensis (truncate tip). The spicule is longer (16���25 ��m) than in F. cosmophyllae n. sp. (12���15 ��m) and F. leucadendrae (14���17 ��m). The bursa is short (arising at 12���28 % of body length), differing from that of F. camaldulensae (50���70 %), F. delegatensae n. sp. (~ 90 %), F. floribundae n. sp. (23���55 %), F. morrisae (75���83 %), F. pimpamensis n. sp. (61���80 %), F. pohutukawa (~ 95 %), and F. viridiflorae (~ 80 %). The male of F. minimus n. sp. has a sturdy spicule compared to the slender spicule of F. brevicauda. Males of F. minimus n. sp. have a relatively shorter pharyngeal gland (b��� 2.9���5.5) and bursa (12���28 % of total body length) than F. microcarpae (b��� 2.0��� 3.1, bursa 24���47 % of total body length).

In southern Victoria, adults were found on native and planted Eucalyptus kitsoniana and E. viminalis between October (mid spring) and early May (mid autumn). In Tasmania, adults were collected in December on Eucalyptus viminalis and by general sweeping on various plants including Eucalyptus pauciflora and unidentified eucalypt species. A single female was collected in June on Eucalyptus sp. The series from the ACT was found in September and that from New South Wales in March on E. viminalis. Adults appear feeding on juvenile foliage and are usually most abundant in opening leaf buds and on very recently expanded leaves. Adults spend most of the time feeding and usually disperse only when disturbed. Mating occurs at feeding sites (Fig. 17). Eggs are most often deposited inside closed apical buds. Females may be induced to lay by insertion of the ovipositor into tight crevices, e.g. between pairs of leaves. In the field, on planted hosts in Victoria, larvae were found between October and May inside apical buds and never on expanding leaves. Densities are typically low (5.9 �� 0.8 larvae per bud, n = 63 observations from seven trees), only rarely reaching high numbers (e.g. 38 larvae in a bud). Larvae produce wax strands (Figs. 18, 19) similar to those of C. eucalypti. Honeydew is encapsulated in the flocculent waxy material (Figs. 18, 19). High numbers of larvae in closed apical leaf pairs induce leaf rolls (Fig. 20). Condensation can be observed inside leaf rolls when opened indicating that they provide larvae with high humidity microhabitats in which to develop. Severely distorted young leaves often do not expand normally (Fig. 20). Leaf rolling was not observed in the field when larval densities were low, e.g. E. kitsoniana seedlings was observed in a nursery (F. Smolders, pers comm.).

Acizzia solanicola was first recorded from S. mauritianum at the Royal Botanic Gardens in Sydney in 1936. It was again collected at Sydney University in 1951, and at Macquarie Pass, about 100 km S of Sydney in 1956. The first record of this species from cultivated eggplant was at Mangrove Mountain, about 60 km N of Sydney in 2005, followed by a subsequent record retrieved from a sticky trap placed near cultivated eggplant at Virginia, 30 km N of Adelaide, South Australia in 2008 (1,200 km W Sydney) (Kent & Taylor 2010). It was collected regularly from S. mauritianum and cultivated S. melongena in the Sydney region during 2007 and 2008. In 2008, it was discovered at Bulahdelah, 180 km N of Sydney, and at Bilpin, 75 km E. In 2009, additional sites were recorded at Nabiac, 220 km N Sydney, Moorland (270 km N), Telegraph Point (310 km N), Kempsey (360 km N) and Glenreagh (450 km N). In late 2009, and early 2010 additional sites were recorded at Stanwell Park (40 km S Sydney), Kiama (100 km S); and the distribution extended to Tomakin (240 km S), Bodalla (270 km S) and Narooma (280 km S). All new records were collected from S. mauritianum. In early 2012, it was discovered on S. mauritianum near Auckland in New Zealand (2,200 km E Sydney), and in November 2012 a population was discovered on a native Australian host, S. petrophilum on Hiltaba Station, Gawler Ranges, South Australia. Its current range extends from Narooma to Glenreagh comprising 750 km of coastal and subcoastal New South Wales, to a single known population on Hiltaba Station in semi-arid central South Australia, and with restricted localities near Adelaide, SA and Auckland, NZ.

Fergusobia floribundae n. sp. is morphologically characterized by the combination of a C-shaped parthenogenetic female with a narrow, arcuate, conoid tail; an arcuate infective female with an hemispherical tail tip; and an arcuate or J-shaped male with angular spicules and short to mid-length peloderan bursa. Morphologically, the parthenogenetic female of Fergusobia floribundae n. sp. is most similar to those of F. delegatensae n. sp., F. diversifoliae n. sp., F. morrisae, F. minimus n. sp., and F. pimpamensis n. sp. The infective female is most similar to F. pimpamensis n. sp. The male is most similar to F. pimpamensis n. sp. From phylogenetic analyses based on sequences of D 2 /D 3 and COI, F. floribundae n. sp. is genetically close to Fergusobia spp. isolated from various gall forms on C. ptychocarpa (F. ptychocarpae), Eucalyptus spp. (Vs 37, 328, 38), and A. near woodsiana (F. pimpamensis n. sp.). The body shape of the parthenogenetic female of F. floribundae n. sp. (C-shape) differs from F. curriei, F. fisheri, F. porosae, F. nervosae, and F. quinquenerviae (open C-shape); from F. camaldulensae, F. pohutukawa, and F. viridiflorae (arcuate to open C-shape); from F. fasciculosae (arcuate) and from F. r i l e y i (almost straight to arcuate). The stylet (6���7 ��m) is shorter than in all other described species of Fergusobia except F. juliae (5���7 ��m) and F. minimus n. sp. (4���8 ��m). In length (352���466 ��m), the female is smaller than those of F. indica (525���626 ��m); but larger than those of F. cajuputiae (221���273 ��m), F. fasciculosae (237���285 ��m), F. fisheri (228���305 ��m), F. jambophila (195���300 ��m), F. leucadendrae (205���303 ��m), (262���347 ��m), F. nervosae (245���309 ��m), F. philippinensis (229���310 ��m), F. quinquenerviae (224���324 ��m), and F. viridiflorae (259���328 ��m). Parthenogenetic females of F. juliae are difficult to separate from F. floribundae n. sp., because they are variable in shape and form: F. floribundae n. sp. mostly has a longer reproductive system, and the circum-oral area is less raised. The parthenogenetic female of F. floribundae n. sp. has a more posterior hemizonid (1 annule anterior to the secretory/ excretory pore) than F. pimpamensis n. sp. (4���5 annules anterior). It is also very similar to those of F. minimus n. sp., but the cephalic region of the latter is never retracted when heat relaxed as it is in F. floribundae n. sp. In shape (arcuate to J), the infective female of F. floribundae n. sp. differs from that of F. brittenae, F. cosmophyllae n. sp., F. curriei, and F. pimpamensis n. sp. (open C-shape); from F. eugenioidae, F. juliae, F. morrisae, and F. ptychocarpae (strongly curved in posterior region); and from F. rileyi (almost straight). In length F. floribundae n. sp. infective females (357���450 ��m) are shorter than those of F. magna (537���633 ��m); and longer than those of F. cajuputiae (239���309 ��m), F. dealbata (307���347 ��m), F. fasciculosae (268���332 ��m), F. leucadendrae (227���291 ��m), F. microcarpae (302���341 ��m), F. nervosae (282 ��m), F. porosae (277���300 ��m), F. quinquenerviae (259���325 ��m), and F. viridiflorae (321 ��m). The ratio a (10.7���13.6) is larger than in F. brevicauda (8.9���10.6) and F. cosmophyllae n. sp. (4���6.8). The shape of the anterior fusiform part of the digestive tract of F. floribundae n. sp. is more slender (length 3���4 times diameter) than that of F. minimus n. sp. (length ~ 2 times diameter). Stylet length (5���8 ��m) is shorter than in F. diversifoliae n. sp. ( 9���11 ��m). The body posterior to the vulva (arcuate with a hemispherical tip) differs in shape from that of F. camaldulensae and F. delegatensae n. sp. (less curved), and F. philippinensis (sub-truncate tip). Fergusobia fisheri has a mostly longer pharyngeal gland (morphometric ratio b��� 3.2���5.7) than F. floribundae n. sp. (b��� 1.9���3.5). The male shape of F. floribundae n. sp. (arcuate to J), differs from that of F. p oro s a e and F. jambophila (almost straight). In total body length (403���570 ��m), it is longer than F. cajuputiae (286���364 ��m), F. fasciculosae (274��� 336 ��m), F. jambophila (200���390 ��m), F. leucadendrae (254���350 ��m), F. microcarpae (311���398 ��m), F. nervosae (277���312 ��m), F. philippinensis (280���390 ��m), F. porosae (270���326 ��m), and F. quinquenerviae (256���329 ��m). The male F. floribundae n. sp. lacks the raised circum-oral area seen in F. magna, F. camaldulensae, F. eugenioidae, and F. juliae. The length of the pharyngeal glands relative to the total body length of F. floribundae n. sp. (b��� 2.7���5.6, mean 4.1) is variable, but is mostly shorter than in F. curriei (2.3���3.7) and F. fisheri (2.3���3.4), to which the male is otherwise morphologically similar. The stylet (5���8 ��m) is shorter than in F. pohutukawa (10���11 ��m) and F. rileyi (11���13 ��m). The tail shape (arcuate with a broadly rounded tip) of these nematodes differs from that of F. viridiflorae (more slender), from F. cosmophyllae n. sp. (broader), and from F. philippinensis (truncate tip). The ratio c (8.7���21.8) of male F. floribundae n. sp. reflects its variability in tail length (19���56 ��m), but is always larger than in F. ptychocarpae (7.6���8.6). The spicules are strongly sclerotised in F. brevicauda, F. brittenae and F. dealbatae, but not in F. floribundae n. sp. The short to medium length bursa (23���55 %), of male F. floribundae n. sp. differs from that of F. delegatensae n. sp. (~ 90 %), F. diversifoliae n. sp. (> 80 %), F. morrisae (75���83 %), and F. pimpamensis n. sp. (60���80 %) (all longer), and from F. minimus n. sp. (12���28 %) (which is shorter). The edges of the bursa are crenate in F. tumifaciens, but not in F. floribunda n. sp. Etymology.

Allocasuarina distyla occurs as a dioecious shrub 1���3 m high in tall heath on sandstone ridges from Port Stephens to east of Cooma in south-western New South Wales. Specimens of Aa. casuarinae collected from Eucalyptus simmondsi (junior synonym of E. ambigua A.Cunn ex DC.) in Tasmania were undoubtedly from nearby Allocasuarina, although A. distyla is not recorded from Tasmania (Wilson & Johnson 1989).

Comments. Aacanthocnema banksiae (Froggatt) is hereby returned to the genus Trioza. Froggatt's (1901) description and illustration of the nymph, the colour, wing shape and alignment of the body of the adult at rest closely resemble many other species of Trioza (see Trioza sp. from Myoporum insulare, Morgan 1984, pl. 22 figs 2, 7) in which the wings are hyaline, wing apex is subangular, medial and cubital cells are characteristically shaped and the female proctiger and subgenital plate are more elongate with pointed apices. These characters differ from both Aacanthocnema and Acanthocasuarina in which the nymphs are heavily-sclerotised, alignment of body of adults at rest lie parallel to its substrate, wings appear less glassy, wing apices are rounded, medial and cubital cells are distinct, and proctiger and subgenital plate are short, rounded or proctiger has an apical hook. It is noted that wing shape and apparent lack of hind tibial spurs may have been the diagnostic characters which led to the tentative placement of the species in Aacanthocnema by Tuthill and Taylor (1955). However, close examination of the unique male slide specimen shows that the wing apex is subangular (although partly obscured by folding) and the hind tibia has 1 outer and 2 inner sclerotised spurs (athough barely visible). Based on these characters, this species is hereby returned to Trioza., Published as part of Taylor, Gary S., Jennings, John T., Purcell, Matthew F. & Austin, Andy D., 2011, A new genus and ten new species of jumping plant lice (Hemiptera: Triozidae) from Allocasuarina (Casuarinaceae) in Australia, pp. 1-45 in Zootaxa 3009 on page 44, DOI: 10.5281/zenodo.278552, {"references":["Froggatt, W.

Male proctiger unipartite, short, without lateral expansions; subgenital plate of male short, rounded; parameres thin, elongate, strongly curved inward towards apex to short with rounded posterior lobe. Female proctiger short, 0.33���0.51 mm in length, 0.5���0.9 times width of head, broadly rounded, with prominent apical hook, ovipositor long, thin and either straight or curved upward, subgenital plate short, narrow, broadly rounded, triangular from lateral aspect. Nymph (Figs 74, 82���83, 92, 110, 126) elongate-narrow, moderately to weakly sclerotised, scale-like; body about 1.80���1.90 times longer than wide; antennae short; cephalothorax entire, usually with a single depression on each of meso- and metathoracic tergites; fore wing pads produced anteriorly, confluent with lateral margin of head; abdominal tergites fused to form caudal plate; caudal plate elongate, narrow, about 1.0��� 1.2 times longer than wide; circum-anal pore field ventral and distant from posterior margin of abdomen; sectasetae short, truncate on margins of head, fore and hind wing margins, and margins of caudal plate; dorsum without sectasetae. Diagnosis. Species of Acanthocasuarina can be distinguished from all other triozids by the following combination of characters: antennae short, 1.0��� 1.7 times width of head, with single rhinarium present subapically on segments 4, 6, 8 and 9, genal processes moderately long, conical, 0.5���0.9 times length of vertex, produced ventrally and delineated from vertex by a prominent overhanging ridge, apex of fore wings broadly rounded, wings clear, vein Rs short, medial cell short, broad, and cubital cell short, broad to moderately elongate, hind tibia with 1 outer and 2 inner spurs, male proctiger short, without lateral expansions, parameres simple, female proctiger short, with a prominent apical upturned process or hook, nymphs elongate-narrow, moderately sclerotised and scale-like. It differs from Aacanthocnema in the arrangement of antennal rhinaria (on segments 4, 6, 8 and 9 in Acanthocasuarina, absent on segment 8 in Aacanthocnema), status of spurs on apical hind tibia (present in Acanthocasuarina, absent in Aacanthocnema), shape of the female proctiger (with an apical hook in Acanthocasuarina, without in Aacanthocnema) and shape of the ovipositor (long, thin and either straight or curved upward in Acanthocasuarina, short, stout and straight in Acacanthocnema). Etymology. From acantho (Greek), spine, refers to the presence of spurs on the hind tibia + casuarina, the colloquial name s.l. for the host. Comments. Acanthocasuarina is the sister taxon to Aacanthocnema and can be clearly separated by the above-mentioned suite of characters. The two genera can be separated from all other triozids from the Casuarinaceae by the following suite of characters: elongate habitus, short Rs vein, and short, triangular radial and cubital fore wing cells, ventrally produced genal processes beneath angular, overhanging apical margin of vertex; short antennae; short broadly-rounded female terminalia, and nymphs elongate, scale-like, with very short, blunt peripheral sectasetae. Being scale-like, the nymphs are clearly adapted to an arid environment, and their elongate habitus and concave ventrum adapted to living on the narrowly cylindrical ���foliage��� of their host. Acanthocasuarina differs from Casuarinicola, and undescribed species of Casuarinaceae-inhabiting Trioza which all have a shorter habitus, with body generally angled upward from the substrate when at rest, short, conical genal processes, and nymphs that are broadly ovate (when slide mounted, although curved around the elongate ���foliage��� when live). It is distinct from an additional suite of undescribed species from the Casuarinaceae in which the antennae are long, the radial and cubital cells of the fore wings are elongate triangular, the genal processes are elongate and produced forward in the same plane as the vertex, and with female terminalia that are generally, some considerably, more elongate., Published as part of Taylor, Gary S., Jennings, John T., Purcell, Matthew F. & Austin, Andy D., 2011, A new genus and ten new species of jumping plant lice (Hemiptera: Triozidae) from Allocasuarina (Casuarinaceae) in Australia, pp. 1-45 in Zootaxa 3009 on pages 27-28, DOI: 10.5281/zenodo.278552

Etymology. Named after the host plant, Allocasuarina luehmannii. Distribution. Recorded from two widely separated localities in inland south-eastern Queensland and inland south-eastern South Australia (Fig. 137). Host plant. Recorded from Allocasuarina luehmannii (R. Baker) L.A.S.Johnson (bull oak). Allocasuarina luehmannii occurs as a 5���15 m tree in woodland in non-calcareous soils from Mareeba, Queensland through central Queensland and New South Wales, to north-western Victoria and eastern South Australia to S of Bordertown (Wilson & Johnson 1989). Comments. This species has been collected rarely from only two, widely separated localities: three specimens from south-eastern Queensland, and one from south-eastern South Australia. Both series were collected from A. luehmannii. Aacanthocnema luehmannii is very close morphologically to Aa. dobsoni, Aa. huegelianae and Aa. torulosae (see Comments under Aa. dobsoni for diagnoses)., Published as part of Taylor, Gary S., Jennings, John T., Purcell, Matthew F. & Austin, Andy D., 2011, A new genus and ten new species of jumping plant lice (Hemiptera: Triozidae) from Allocasuarina (Casuarinaceae) in Australia, pp. 1-45 in Zootaxa 3009 on page 23, DOI: 10.5281/zenodo.278552, {"references":["Taylor, G.

Nymph. Unknown. Etymology. Named after Dr Daniel Burckhardt, Naturhistorisches Museum, Basel, Switzerland, in recognition of his research on the systematics of the Psylloidea, and who collected the type material. Distribution. Recorded from a single locality in the McPherson Range on the subcoastal montane border of southern Queensland and northern New South Wales (Fig. 136). Host plant. Recorded from Allocasuarina torulosa (Aiton) L. Johnson (forest sheoak). Allocasuarina torulosa occurs as a 5���20 m tree in an understory in open forest to tall open forest, in coastal and subcoastal mountain regions in eastern Australia, from the McIllwraith Ranges, Qld to Macquarie Pass and Jenolan Caves, NSW (Wilson & Johnson 1989). Comments. Aacanthocnema burckhardti and Aa. casuarinae are the only two species of Aacanthocnema with pigmentation along most fore wing veins (R+M+Cu, M, M 1 + 2, M 3 + 4, Cu, Cu 1 a, Cu 1 b and distal portion of Rs). Aacanthocnema dobsoni, Aa. huegelianae and A. torulusae lack pigmentation along wing veins, and in Aa. luehmannii, the pigmentation is restricted to the anterior half of vein Cu 1 a. Aacanthocnema burckhardti differs from Aa. casuarinae by: its larger size for most characters measured, see Tables 1���3; the shape of the vertex (proportionally shorter and broader with higher VL:VW and VL:HW ratios in Aa. burckhardti, compared to proportionally longer and narrower with lower VL:VW and VL:HW ratios in Aa. casuarinae; the shape of the anterior margin of the vertex (rather flat from dorsal aspect in Aa. burckhardti, somewhat rounded in Aa. casuarinae); the length of antennae (proportionally longer with high AL:HW ratio in Aa. burckhardti and proportionally shorter with low AL:HW ratio in Aa. casuarinae); in the shape of the fore wings (more elongate with pointed apex in Aa. burckhardti compared to shorter with rounded apex in Aa. casuarinae).

Distribution. Recorded from Adelaide and environs, Fleurieu Peninsula, Yorke Peninsula and Kangaroo Island in southern South Australia, Canberra in the Australian Capital Territory, and Hobart and environs in Tasmania (Fig. 136). Host plant. Recorded from Allocasuarina verticillata (Lam.) L.Johnson (drooping sheoak). Allocasuarina verticillata occurs as a 4���10 m tree in grassy woodland to rocky sea-coasts and dry rocky hills and ridges inland, from central New South Wales, Victoria, northern and eastern Tasmania, and southern South Australia, including Yorke and Eyre Peninsulas and Kangaroo Island (Wilson & Johnson 1989). Note that Casuarina stricta and C. quadrivalvis (as cited on early labels) are junior synonyms of A. verticillata. Allocasuarina luehmannii (Miq.) L. Johnson, C. cunninghamiana Miq. and A. cristata Miq. are unlikely hosts: where these hosts were recorded (see label data), trees were ornamentals in close proximity in an arboretum. In each case very few insect specimens were collected, yet they were abundant on neighbouring trees of A. verticillata (GST, personal observation). Comments. Froggatt (1903) incorrectly cited the host plant of this species as Eucalyptus amygdalina Labill. It is probable also that his description of the nymph and illustrations of the wing and galled foliage are of Schedotrioza tasmaniensis (Froggatt). Morgan (1984) mis-identified A. dobsoni as A. casuarinae: the fore wing illustrated is without infuscation along wing veins, and the localities cited (Adelaide Plains, Mt Lofty Ranges and Kangaroo Island) and host (C. stricta = junior synonym of A. verticillata) are consistent for this species. Meiotic karyotypes and the structure of the testes of Aa. dobsoni were examined in Maryańska-Nadachowska et al. (2001). They exhibited a male diploid karyotype of 2 n= 25 (24 + X) which is consistent with the majority of the Psylloidea and most likely represents the ancestral condition (Maryańska-Nadachowska et al. (2001). Aa. casuarinae + Aa. dobsoni Aa. huegelianae + Aa. luehmannii Aa. torulosae Ac. acutivalvis + Ac. campestris + Ac. diminutae + Ac. muellerianae Ac. tasmanica Ac. verticillatae continued.

Aacanthocnema dobsoni, Aa. huegelianae, and Aa. torulosae lack pigmentation along wing veins and Aa. luehmannii has pigmentation restricted to the anterior half of vein Cu 1 a. In Aa. dobsoni width of head, length of antennae and corresponding AL:HW ratio is moderate, in Aa. huegelianae head wide and antennae moderately long and corresponding AL:HW ratio low, in Aa. luehmannii head moderately wide, antennae long and AL:HW ratio high, and in Aa. torulosae head narrow, antennae moderately long and AL:HW ratio high; in Aa. dobsoni and Aa. luehmannii length and width of vertex and corresponding VL:VW and VL:HW ratios are moderate, in Aa. huegelianae vertex short and wide with VL:VW and VL:HW ratios very low, and Aa. torulosae vertex moderately long and narrow and corresponding VL:VW and VL:HW ratios high; in Aa. dobsoni and Aa. luehmannii male proctiger elongate and in Aa. huegelianae and Aa. torulosae short and rounded; in Aa. dobsoni, Aa. huegelianae and Aa. torulosae male aedeagus terminates in a moderate bulb and in Aa. luehmannii it is distinctly larger; in Aa. dobsoni and Aa. huegelianae parameres are parallel-sided from lateral aspect and strongly incurved and in Aa. luehmannii and Aa. torulosae parameres have a bulbous base, narrowing to a pointed apex; in Aa. dobsoni and Aa. torulosae female proctiger short with dorso-posterior margin rounded in lateral aspect, and in Aa. huegelianae and A. luehmannii it is short and dorso-posterior margin is angular., Published as part of Taylor, Gary S., Jennings, John T., Purcell, Matthew F. & Austin, Andy D., 2011, A new genus and ten new species of jumping plant lice (Hemiptera: Triozidae) from Allocasuarina (Casuarinaceae) in Australia, pp. 1-45 in Zootaxa 3009 on pages 16-19, DOI: 10.5281/zenodo.278552, {"references":["Froggatt, W.

Etymology. From ���Warrigal��� (locality) + ensis (L.) belonging to, from. Named after ���Warrigal���, 25 km NW of Baradine, NSW, from which the type specimens were collected. Distribution. Recorded from near Pilliga Scrub in ���mid-western��� New South Wales (Fig. 51). Host plant. Recorded from C. cristata. Casuarina cristata (belah) occurs as a 10���20 m tree in clay calcareous soils in subcoastal regions in eastern Australia (usually west of the Great Dividing Range, from Clermont, Qld to Temora, NSW. It frequently produces root suckers and often forms pure (often clonal) stands as an open forest or woodland (Wilson & Johnson 1989). Comments. This species can be distinguished from all other species in the genus by the female with heavily maculated fore wings. The male has clear wings. Casuarinicola warrigalensis sp. nov. has very short genal cones, considerably shorter that all other species in the genus; the pronotum has a weak, rounded median lobe (which is produced anteriorly in C. australis sp. nov., C. nigrimaculatus sp. nov., C. mucronalatus sp. nov. and C. novacaledonica sp. nov.); the fore wing is elongate oval with a rounded apex, cell m 1 is short and broad and cell cu 1 is narrow and high, each with a low cell value (shared with C. australis sp. nov., C. nigrimaculatus sp. nov. and C. novacaledonica sp. nov., but differs from C. mucronalatus sp. nov. in which the fore wing has a subangular apex, cell m 1 is long and narrow and cell cu 1 is short and broad, each with a high cell value); and, the hind tibia is distinctly long (differs from C. australis sp. nov., C. nigrimaculatus sp. nov. and C. mucronalatus sp. nov. with a moderate hind tibia moderate tibia length to head width ratio and from C. novacaledonica sp. nov. with a short hind tibia and low length to head width ratio).

Final instar nymph (Fig. 11). As for generic description (see above). Measurements and ratios as in Tables 6���7. Etymology. From australis (Latin), southern, austral; refers to distribution, Australia. Distribution. Recorded from coastal and subcoastal eastern Australia from Cape Tribulation (Queensland) to near Sydney (New South Wales), inland New South Wales and South Australia, and subcoastal Western Australia from Denham to south of Perth (Fig. 50). Host plants. Recorded from C. cristata Miq., C. cunninghamiana, C. equisetifolia, C. glauca, C. obesa Miq and C. pauper F.Muell. ex L.Johnson. Its most common host, C. equisetifolia (coastal sheoak) occurs as a 6���35 m tree along beaches and on rocky headlands along the coastlines of northern and north-eastern Australia, Madagascar, Burma to Vietnam, Malesia, Melanesia and Polynesia. There are two subspecies: subsp. equisetifolia, which occurs from near Darwin (NT) to Cairns (Qld), Burma through Malesia to Vietnam, Melanesia and Polynesia, and subsp. incana, which occurs from near Cairns to near Sydney (NSW), New Caledonia and southern Vanuatu (Wilson & Johnson 1989). Casuarina obesa (swamp sheoak) grows in brackish or saline situations along rivers, salt lakes or estuaries in south-western Western Australia, excluding the extreme SW, and with a disjunct population from a few isolated localities in the Wimmera region of western Victoria (Wilson & Johnson 1989). For C. cristata, refer to C. warrigalensis Taylor sp. nov., for C. cunninghamiana and C. glauca, refer to C. nigrimaculatus Taylor sp. nov., and for C. pauper, refer to C. mucronalatus Taylor sp. nov. Comments. This species can be distinguished from all other species in the genus by the female having three incomplete black terminal bands in the fore wing. The male has clear wings. Casuarina australis sp. nov. has short conical genal processes (shared with C. nigrimaculatus sp. nov., C. mucronalatus sp. nov. and C. novacaledonica sp. nov., but differs from C. warrigalensis sp. nov. in which they are considerably shorter); the pronotum has a prominent median lobe (which is less prominent in C. nigrimaculatus sp. nov., C. mucronalatus sp. nov. and C. novacaledonica sp. nov. and weak and rounded in C. warrigalensis sp. nov.); the fore wing is elongate oval with a rounded apex, cell m 1 is short and broad and cell cu 1 is narrow and high, each with a low cell value (shared with C. nigrimaculatus sp. nov., C. novacaledonica sp. nov. and C. warrigalensis sp. nov., but differs from C. mucronalatus sp. nov. in which the fore wing has a subangular apex, cell m 1 is long and narrow and cell cu 1 is short and broad, each with a high cell value); and, the hind tibia is moderate in length with a moderate tibia length to head width ratio (shared with C. nigrimaculatus sp. nov. and C. mucronalatus sp. nov., but differs from C. novacaledonica sp. nov. with a short hind tibia and low length to head width ratio, and C. warrigalensis sp. nov. with a long hind tibia and high length to head width ratio). Casuarinicola australis sp. nov. occurs on all Australian species of Casuarina. It is the only species known from C. equisetifolia and C. obesa., Published as part of Taylor, Gary S., Austin, Andy D., Jennings, John T., Purcell, Matthew F. & Wheeler, Gregory S., 2010, Casuarinicola, a new genus of jumping plant lice (Hemiptera: Triozidae) from Casuarina (Casuarinaceae), pp. 1-27 in Zootaxa 2601 on pages 4-13, DOI: 10.5281/zenodo.197605, {"references":["Wilson, K.

Etymology. From nigri, black, dark + maculatus (Latin) spot, blemish; refers to dark markings on fore wing. Distribution. Recorded from coastal and subcoastal eastern Australia from near Cooktown (Queensland) to Canberra (Australian Capital Territory), including inland ���mid-western��� New South Wales (Fig. 51). Host plants. Recorded from C. cunninghamiana and C. glauca. Casuarina cunninghamiana (river sheoak) occurs as a 15���35 m tree along permanent to semi-permanent watercourses from Daly River, NT and east to the Gulf of Carpentaria in northern Australia, and in eastern Australia from near Chillagoe in northern Qld to Bega in NSW. There are two subspecies: subsp. cunninghamiana, that occurs from near Chillagoe, Qld to near Bega, NSW, and subsp. miodon that occurs from Daly River, NT to the Gulf of Carpentaria, Qld (Wilson & Johnson 1989). Casuarina glauca (swamp oak) occurs as an 8���20 m tree in brackish situations along estuaries and streams in coastal and subcoastal regions in eastern Australia, from Yeppoon, Qld to Bermagui, NSW. It frequently produces root suckers and often forms pure stands as an open forest or woodland (Wilson & Johnson 1989). Comments. This species can be distinguished from all other species in the genus by the female having a broad black terminal band in the fore wing. It is the only species in which the male has a fore wing with dark markings, although this character is absent in some specimens. Casuarinicola nigrimaculatus sp. nov. has short conical genal processes (shared with C. australis sp. nov., C. mucronalatus sp. nov. and C. novacaledonica sp. nov., but differs from C. warrigalensis sp. nov. in which they are considerably shorter); the pronotum has a moderate median lobe (shared with C. mucronalatus sp. nov. and C. novacaledonica sp. nov., but is more prominent in C. australis sp. nov. and reduced in C. warrigalensis sp. nov); the fore wing is elongate oval with a rounded apex, cell m 1 is short and broad and cell cu 1 is narrow and high, each with a low cell value (shared with C. australis sp. nov., C. novacaledonica sp. nov. and C. warrigalensis sp. nov., but differs from C. mucronalatus sp. nov. in which the fore wing has a subangular apex, cell m 1 is long and narrow and cell cu 1 is short and broad, each with a high cell value); and, the hind tibia is moderate in length with a moderate tibia length to head width ratio (shared with C. australis sp. nov. and C. mucronalatus sp. nov., but differs from C. novacaledonica sp. nov. with a short hind tibia and low length to head width ratio, and C. warrigalensis sp. nov. with a long hind tibia and high length to head width ratio). C. nigrimaculatus sp. nov. occurs on C. cunninghamiana and C. glauca, which are also hosts for C. australis sp. nov., Published as part of Taylor, Gary S., Austin, Andy D., Jennings, John T., Purcell, Matthew F. & Wheeler, Gregory S., 2010, Casuarinicola, a new genus of jumping plant lice (Hemiptera: Triozidae) from Casuarina (Casuarinaceae), pp. 1-27 in Zootaxa 2601 on pages 13-14, DOI: 10.5281/zenodo.197605, {"references":["Wilson, K.

Etymology. From mucron, sharp point + alatus (Latin), wing; refers to the subangular apex of the fore wing. Distribution. Recorded from inland western to ���mid-western��� New South Wales (Fig. 51). Host plants. Recorded from C. cristata and C. pauper. Casuarina pauper (black oak) occurs as a 5���15 m tree in inland southern Australia, from far south-western Queensland, far western New South Wales, northwestern Victoria, inland South Australia and inland southern Western Australia (Wilson & Johnson 1989). For C. cristata, refer to C. warrigalensis Taylor sp. nov. Comments. This species can be distinguished from all other species in the genus by the female having black pigmentation mostly in the dorso-apical quadrant, confluent with wing margins at termination of veins Rs, M 1 + 2, M 3 + 4, Cu 1 a, and Cu 1 b, of the fore wing. The male has clear wings. Casuarina mucronalatus sp. nov. has short conical genal processes (shared with C. australis sp. nov., C. nigrimaculatus sp. nov. and C. novacaledonica sp. nov., but differs from C. warrigalensis sp. nov. in which they are considerably shorter); the pronotum has a moderate median lobe (shared with C. nigrimaculatus sp. nov. and C. novacaledonica sp. nov., but is more prominent in C. australis sp. nov. and reduced in C. warrigalensis sp. nov); the fore wing is elongate oval with a subangular apex, cell m 1 is long and narrow and cell cu 1 is short and broad, each with a high cell value (differs from C. australis sp. nov., C. nigrimaculatus sp. nov., C. novacaledonica sp. nov. and C. warrigalensis sp. nov., in which the fore wing has a rounded apex, cell m 1 is short and broad and cell cu 1 is narrow and high, each with a low cell value); and, the hind tibia is moderate in length with a moderate tibia length to head width ratio (shared with C. australis sp. nov. and C. nigrimaculatus sp. nov., but differs from C. novacaledonica sp. nov. with a short hind tibia and low length to head width ratio, and C. warrigalensis sp. nov. with a long hind tibia and high length to head width ratio). Casuarinicola mucronalatus sp. nov. occurs on C. cristata and C. pauper, which are also hosts for C. australis sp. nov. and C. warrigalensis sp. nov., Published as part of Taylor, Gary S., Austin, Andy D., Jennings, John T., Purcell, Matthew F. & Wheeler, Gregory S., 2010, Casuarinicola, a new genus of jumping plant lice (Hemiptera: Triozidae) from Casuarina (Casuarinaceae), pp. 1-27 in Zootaxa 2601 on pages 16-18, DOI: 10.5281/zenodo.197605, {"references":["Wilson, K.

Spicules paired, angular at about 33 % of length, with manubrium and shaft longer than blade; moderately sclerotised; manubrium similar to or wider than shaft, not offset; blade narrows gradually to bluntly rounded tip with concavity on distal edge; opening terminal (Figs 9, 15). Inconspicuous muscles associated with cloaca. Tail arcuate, ventrally concave, conoid; 2���3.3 �� as long as diameter at cloaca; rounded tip (Fig. 12). Diagnosis (Emended). Fergusobia magna is morphologically characterized by the combination of a relatively large, variably shaped parthenogenetic female with a slender conoid tail and rounded pointed tip; a relatively large arcuate infective female with a long slender tail with a pointed tip and a relatively anterior vulva; and a relatively large, arcuate, open C or J-shaped male with spicules angular at about 33 % of their length, slender tail and mid-length peloderan bursa. From phylogenetic analyses based on sequences of D 2 / D 3 and COI, there was a well-supported clade (100 % Bayesian, 100 % NJ, 100 % MP) of six isolates of F. magna from north-eastern and south-eastern Queensland (Figs 16���17). Siddiqi (1986) described F. m a g n a from parthenogenetic females only from galls on a twig of Eucalyptus sp. at Indooroopilly, Queensland. Galls meeting the description given by Siddiqi are found on most specimens of C. tessellaris, which grows commonly in the Indooroopilly area and also along the Queensland coast (Davies & Giblin-Davis, unpub. obs.). The galls are terminal and axial shoot bud galls, but the leaves have dehisced and the galls appear to be ���stem��� galls. Parthenogenetic females collected from the galls in this study generally fit the description given by Siddiqi. They have similar body length (here 418���619 ��m vs Siddiqi���s 500���780 ��m); tail length (44���96 ��m vs 60���95 ��m); tail shape (elongate, conoid, tapering to small rounded tip); V (77���89 vs 81 %); ratio a (8���18 vs 12���18); ratio c (6.3���14.2 vs 6.6���10.5); and ratio c��� (2.5���4.8 vs 3.6��� 4.8). Scanning electron micrographs of the cephalic region of F. m a g n a from the collections described here (drawn in Figs 13, 14) suggest that it is less laterally compressed than is apparent in Siddiqi���s (1986) micrograph. However, this may reflect differences in the quality of the preparation of the micrographs. Therefore, because the parthenogenetic female nematodes collected here from C. tessellaris generally meet the description and diagnosis given by Siddiqi, and despite lack of precise data on gall form, plant and insect host species, morphology and morphometrics of male and pre-infective female nematodes, and collection site, the nematodes are here re-described as F. magna. In having parthenogenetic females that are longer (418���689 ��m) than F. brevicauda Siddiqi, 1994 (260��� 390 ��m), F. c u r r i e i Fisher & Nickle 1968 (275���370 ��m), F. cajuputiae Davies & Giblin-Davis 2004 (221���273 ��m), F. dealbatae Davies & Giblin-Davis 2004 (250���410 ��m), F. f i s h e r i Davies & Lloyd, 1996 (228���305 ��m), Davies & Giblin-Davis 2004 (245���309 ��m), F. jambophila Siddiqi, 1986 (195���300 ��m), F. leucadendrae Davies & Giblin-Davis 2004 (205���303 ��m), F. nervosae Davies & Giblin-Davis 2004 (245��� 309 ��m), F. philippinensis Siddiqi 1996 (229���310) ��m, F. pohutukawa Taylor, Davies, Martin & Crosby, 2007 (244���365 ��m), F. quinquenerviae Davies & Giblin-Davis 2004 (224���324 ��m), F. tumifaciens (Currie 1937) Wachek 1955 (415 ��m), and F. viridiflorae Davies & Giblin-Davis 2004 (259���328 ��m), F. magna differs from all described species of Fergusobia except F. indica (Jairajpuri, 1962) Siddiqi, 1986 (525���626 ��m) and F. ptychocarpae Davies, 2008 (320���461 ��m) and F. brittenae Davies, 2010 (328���461 ��m). Parthenogenetic females of F. magna are separated from F. indica by the form of the cephalic region (dome-like in F. indica), by having a shorter stylet (8���11 ��m vs 12���15 ��m), and because the latter is not ovoviviparous. Fergusobia ptychocarpae and F. brittenae have a shorter tail than F. magna (respectively, tail length = 13���46 ��m and 23��� 37 ��m vs 44���96 ��m; and c = 14 (8���27) and 15 (10���19) vs 8 (6.6���10.5)). On the basis of body length, infective females of F. magna can be separated from other described species of Fergusobia where the stage is known (537���633 ��m vs 330���410 ��m in F. brevicauda, 417���489 ��m in F. curriei, 239���309 ��m in F. cajuputiae, 307���347 ��m in F. dealbatae, 241���395 ��m in F. f i s h e r i, 227���291 ��m in F. leucadendrae, 282 ��m in F. nervosae, 290���370 ��m in F. philippinensis, 259���325 ��m in F. quinquenerviae, and 321 ��m in F. viridiflorae) except F. brittenae (375���550 ��m). The position of the vulva in infective females of F. magna (51���63 %) is more anterior than in other described species of Fergusobia (76���85 in brevicauda, 72���77 in F. brittenae, 76���82 in F. c u r r i e i, 81���86 in F. cajuputiae, 80���84 in F. dealbatae, 76���88 in F. f i s h e r i, 80���81 in F. leucadendrae, 82 in F. nervosae, 70���82 in F. philippinensis, 79���87 in F. quinquenerviae, and 79 % in F. viridiflorae). The size and form of the spicule in male F. magna separates it from all other described species of Fergusobia. In length (30���37 ��m), the spicule is longer than in F. brevicauda (21���27 ��m), F. brittenae (19���25 ��m), F. cajuputiae (16���20 ��m), F. dealbatae (18���22 ��m), F. f i s h e r i (16���20 ��m), F. jambophila (15���20 ��m), F. leucadendrae (14���17 ��m), F. nervosae (16���19 ��m), F. philippinensis (19���23 ��m), F. pohutukawa (19���24 ��m), F. ptychocarpae (19���21 ��m), F. quinquenerviae (16���20 ��m), F. tumifaciens (21 ��m), and F. viridiflorae (18���20 ��m). In having spicules with manubrium and shaft forming 66 % of their length, and separated from the blade by an angle, F. magna differs from other described species in which the angle in the spicule is at about 50 %, or the spicule is arcuate., Published as part of Davies, Kerrie A., Giblin-Davis, Robin M., Ye, Weimin, Taylor, Gary S. & Thomas, Kelley, 2010, Nematodes from galls on Myrtaceae.

Female: terminalia as in Fig. 19; proctiger and subgenital plate elongate triangular from lateral aspect. Nymph. Unknown. Comments. A total of 140 individuals of other plant species, including Acacia longifolia and A. ulicifolia,, known hosts of A. acaciaedecurrentis (Froggatt), A. acaciaejuniperinae (Froggatt), A. conspicua (Tuthill) and A. frenchi (Froggatt) (Hollis 2004), were sampled in the immediate vicinity of the Pultenaea glabra population, but failed to yield any specimens of A. keithi. Therefore, although nymphs were not detected on P. glabra, there was little possibility that the specimens were from plant species other than this host at this location (Moir, unpublished data). Acizzia keithi sp. n. can be distinguished from all other species of Acizzia by the following suite of characters: antenna short, 1.0���1.2 times width of head (Fig. 11); genal processes short, 0.23��� 32 times length of vertex, with broad, blunt apices (Fig. 11); both sexes with characteristically mottled wings (Figs 12���16); male proctiger with thin, erect apical node and broadly-triangular lateral (posterior) lobes without terminal distal appendages (Fig. 17); apical segment of aedeagus thin, with little-expanded apex (Fig. 17); hind margin of parameres with inconspicuous basal node (Fig. 17); inner face of parameres with short rod-shaped setae in a medial field, and a short blunt, triangular node at basal third (Fig. 18); female terminalia long, proctiger and subgenital plate elongate triangular from lateral aspect (Fig. 19). Etymology. Named in honour of Dr David Keith, who suggested Pultenaea glabra as a good candidate to search for co-threatened insects, and provided financial, logistical and intellectual support to ensure this sampling was possible. This ultimately led to the discovery of the new Acizzia species. Host-plant association. Pultenaea is a new generic host record for Acizzia, indeed for any Psylloidea. The genus Pultenaea is endemic to Australia with 116 species (Orthia et al. 2005). It is mainly confined to shrublands or woodlands of south-western and eastern Australia, and is absent from arid or tropical regions (Orthia et al. 2005). The recorded host species, Pultenaea glabra, is an erect shrub to 3 m and is often associated with swamps or damp depressions in highland country (700���2200 m above sea level) (de Kok & West 2002). Pultenaea glabra is nationally listed as ���vulnerable��� and the key threatening processes are inappropriate fire regime, dieback disease (caused by Phytophthora cinnamomi), and habitat clearing (Fraser et al. 2004). It has a disjunct distribution along the east coast of Australia with the largest populations in the central and northern tablelands of New South Wales, but restricted populations also occur in the Dandenong Range of Victoria, and a single population has been recorded from the central coast of Queensland (CHAH 1995-2002; de Kok & West 2002; Fraser et al. 2004). Therefore, it is possible that additional populations of Acizzia keithi will be discovered with further sampling of these disjunct host populations, although we point out that a search of other entomological collections (e.g., NSW Department of Primary Industries, Australian National Insect Collection, Australian Museum, Western Australian Museum, etc) failed to yield additional specimens from other localities. Alternatively, the insect assemblage may change across the range of P. glabra, and A. keithi may only occur in the one locality (see Andrew & Hughes 2005 for examples of assemblages of Hemiptera changing along such a latitudinal gradient). Other host associations recorded on Pultenaea glabra include seed predators within the beetle family Bruchidae (Auld 1991), and other sapfeeders, lacebugs within the genus Radinacantha (Moir, in press), although no host-specific association has been documented to date., Published as part of Taylor, Gary S. & Moir, Melinda L., 2009, In threat of co-extinction: two new species of Acizzia Heslop-Harrison (Hemiptera: Psyllidae) from vulnerable species of Acacia and Pultenaea, pp. 20-32 in Zootaxa 2249 on pages 27-29, DOI: 10.5281/zenodo.190755, {"references":["Hollis, D.

Acizzia veski is the first species of Acizzia to be described from Western Australia, and is considered endemic to that State. Only three other species have been recorded from Western Australia; A. acaciaedecurrentis (on A. cyclops: Van Der Berg 1980), A. acaciaebaileyanae and A. uncatoides (Hollis 2004). However, these species of Acizzia may be native to eastern Australia, and introduced in Western Australia, as they have been in other regions of the world (see Hollis 2004). Acizzia veski sp. n. can be distinguished from all other described species of Acizzia by the following suite of characters: antenna long, 2.3���2.6 times width of head (Fig. 1); genal processes moderate in length, 0.55��� 0.66 times length of vertex, with broadly rounded apices (Fig. 1); both sexes with characteristically mottled wings (Figs 2���6); male proctiger with thin, reclinate apical node and broadly-rounded lateral (posterior) lobes each with a thin terminal distal appendage (Fig. 7); apical segment of aedeagus with an asymmetric bulbous apex with an anterior hook (Fig. 7); inner face of parameres with rod-shaped setae (Fig. 8); female terminalia short, proctiger broadly rhomboid, and subgenital plate broadly triangular from lateral aspect (Fig. 9). Etymology. Named in honour of Dr Peter Vesk, who has provided financial, logistical and intellectual support for the investigation into co-extinction of Australian insects on plants that resulted in the discovery of this new species. Host-plant association. The plant genus Acacia is host to a number of described species and many undescribed species of Acizzia (Yen 2002). The genus Acacia is widely distributed with over 1350 species world-wide, however, recent work suggests that Acacia comprises several genera (Maslin et al. 2003; Orchard & Maslin 2003). Within Australia there are 948 species of Acacia in the subgenus Phyllodineae distributed in all states and territories and adapted to many different habitats (e.g., see http://www.anbg.gov.au/cpbr/ taxonomy/acacia-conserved- 2004.html). Acacia veronica is a small, often spindly, tree (1.5��� 7 m) restricted mainly to watercourses in the Stirling Ranges of Western Australia, with smaller individuals growing at higher altitudes, and is often associated with marri (Corymbia calophylla) woodlands. It is listed for ���Priority 3 ��� conservation because of its restricted distribution, however, key threatening processes most likely include climate change (Barrett et al. 2008), inappropriate fire regime and habitat clearing. The closest relatives of Acacia veronica appear to be eastern state species (Maslin 1989; Maslin pers. comm. 2008). One of us (MLM) searched for known populations of A. veronica to sample for insects, which resulted in five populations of the plant rediscovered, four previously recorded populations found to be extinct, and a newly discovered population located. However, of the six populations of A. veronica sampled, only one yielded A. veski, suggesting that although the host has a low ���priority 3 ��� conservation status, the psyllid is critically endangered (Moir et al., in press). No other host associations have been previously recorded, however, a diverse assemblage of insects was collected from A. veronica during sampling, including at least one weevil and chrysomelid beetle that may also be restricted to A. veronica (Moir, unpublished data)., Published as part of Taylor, Gary S. & Moir, Melinda L., 2009, In threat of co-extinction: two new species of Acizzia Heslop-Harrison (Hemiptera: Psyllidae) from vulnerable species of Acacia and Pultenaea, pp. 20-32 in Zootaxa 2249 on pages 21-26, DOI: 10.5281/zenodo.190755, {"references":["Van Der Berg, M.
