From Latin convector, noun in apposition, masculine = the fellow traveller, passenger, referring to its broad adventitious distribution along with its hosts. Distribution. Australia (Northern Territory); adventive in Brunei, Cambodia, India (Odisha), Laos, Malaysia (Sabah), Singapore, Thailand and the United States of America (Florida). Host plants. Acacia auriculiformis A.Cunn. ex Benth. and A. mangium Willd. (Fabaceae, Caesalpinioideae, mimosoid clade). Acacia auriculiformis, northern black wattle or ear-pod wattle, occurs in Australia, Papua New Guinea and Indonesia. Its distribution in Australia comprises the north of the Northern Territory including several off-shore islands as well as the Cape York Peninsula and the Torres Strait Islands, Queensland (Boland et al. 1990). In Papua New Guinea it occurs in the Central and Western Provinces, and extends into Irian Jaya (Papua Barat) and the Kai Islands of Indonesia. Acacia auriculiformis is naturalised widely in Africa, the Americas, Asia and Oceania (Vélez-Gavilán 2016). Acacia mangium, brown salwood or black wattle, has a similar distribution. It originates from Australia (northeastern Queensland), the Western Province of Papua New Guinea, Irian Jaya and the eastern Maluku Islands (Francis 2003). It has been planted throughout the tropics and is naturalised in many areas (CABI 2021). Comments. Acizzia convector sp. nov. is well characterised by its fore wing pattern and structure of the male and female terminalia in the adults as well as the chaetotaxy in the immatures. It resembles Acizzia beieri Loginova and A. jucunda Tuthill in the male proctiger with a long apical portion and a spine-like process adjacent to the posterior lobe, as well as the paramere with an anterior tooth on the fore margin. It differs from the former in the presence of a dark fore wing pattern and from the latter in two metabasitarsal spurs and the female terminalia bearing hooked long setae posteriorly., Published as part of Taylor, Gary S., Halbert, Susan E., Tripathy, Ashirwad & Burckhardt, Daniel, 2023, A new Australian species of invasive psyllid, Acizzia convector Burckhardt & Taylor, sp. nov.

Open C shape when relaxed by heat with most curvature in posterior half (Fig. 2B, H); maximum body diameter at mid-body length or at vulva; body tapers gradually posterior to anus to a tip that is almost hemispherical. Cuticle obscurely annulated, Cephalic region not offset, domed shape; circum-oral area flat; stylet slender, weakly sclerotised with tiny round basal knobs ~1µm wide; cone ~ 40% of length. Orifice of dorsal pharyngeal gland often obscure, less than height of a stylet knob posterior to knobs. Anterior fusiform part of digestive tract little expanded, occupying 46 (33-73)% of body diameter, length 4.2 (3.5–5.2) times diameter. Pharyngeal glands extending over intestine, occupying 53 (32–84)% body diameter, distance from head to posterior end of glands being 23 (19–26%) of total body length. Secretory/excretory pore opens near distal end of pharyngeal glands, opposite or posterior to gland nucleus; duct obscure; secretory/excretory cell not seen. Hemizonid immediately anterior to pore (Fig. 2B). Uterus packed with sperm in inseminated females; vagina perpendicular to body axis; reproductive tract extending to nerve ring. Vulva a transverse slit, vulval lips small but clearly raised ~ 1 µm, no vulval plate present. Anus an obscure pore.

Cuticular annules ~1µm wide; strong longitudinal striae in sub-cuticle apparent with light microscope; lateral fields faint, lines not discernible. Cephalic region occupying 80–90% anterior body diameter, clearly offset (Fig. 2F), ~ 1.5–3 µm high; circumoral area flat or raised, with lightly sclerotised framework; sturdy stylet with cone 40% of length, knobs round, 2 µm wide. Orifice of dorsal pharyngeal gland ~ 1 µm behind knobs. Anterior fusiform part of digestive tract occupying 67 (37–82)% of body diameter, length 2.1 (1.5–2.7) times diameter. Pharyngeal glands extending over intestine, occupying 72 (67–78)% of body diameter, distance from head to posterior end of glands being 27 (23– 31)% of total body length. Secretory/excretory pore opens posterior to nucleus of pharyngeal gland; duct non-refractile; secretory/ excretory cell not seen. Hemizonid extending over two annules, immediately or up to 6 annules anterior to pore. Reproductive tract with single testis, usually extending part-way along pharyngeal gland and may reach nerve ring, flexed in some specimens; testis, seminal vesicle and vas deferens not clearly differentiated. Bursa smooth; not prominent; arises 20 – 30% along length of body; apparently terminates just anterior to tail tip (Fig. 2C). Spicules paired, stocky, angular at ~40% length; relatively strongly sclerotised; manubrium similar to or wider than shaft, not offset; blade narrows gradually to bluntly rounded tip with concavity on distal edge; spicular nerve opening terminal (Fig. 2N). Inconspicuous muscles associated with cloaca. Tail arcuate, ventrally concave, subconoid; length 1.2–1.9 times diameter at cloaca; broadly rounded tip (Fig. 2J). Diagnosis and relationships. Fergusobia robustae n. sp. is morphologically characterized by the combination of a small, C-shaped parthenogenetic female with a short cylindroid tail with a broadly rounded tip; an arcuate to C-shaped, relatively broad infective female with a tail tip that is almost hemispherical; and an arcuate male with a strong angular spicule and a bursa arising at 30–40% of body length. Morphologically, F. robustae n. sp. is similar to F. brittenae, F. cosmophyllae, F. floribundae, and F. minimus, and all were collected from TLBGs. Fergusobia floribundae was collected from Angophora, but the other close species were collected from host plants classified as Eucalyptus subgenus Symphyomyrtus, as was E. robusta. While third instar larvae of flies associated with F. floribundae lack a dorsal shield, those associated with F. robustae n. sp. and the other species mentioned above have a dorsal shield with teeth. Molecular sequences for F. robustae n. sp. are not available, but morphological differences between them and nematodes from similar gall forms, related host plants and flies with similar dorsal shields suggest that they are separate species. They are separated from F. brittenae in lacking the enormous secretory/excretory cell present in the latter, and by the form of the lateral fields. In F. brittenae, the fields comprise a ribbon of broken striae, but in F. robustae n. sp. they comprise two separated bands of striae. The parthenogenetic female of F. cosmophyllae (354–406 µm) is larger than that of F. robustae n. sp. (249–358 µm). Further, spicule length of F. robustae n. sp. (17–21 µm) is larger than in F. cosmophyllae (12–15 µm). Fergusobia robustae n. sp. was collected from E. robusta, from Section Latoangulatae, i.e., its host was genetically dissimilar to that of the morphometrically similar F. minimus, collected from E. tereticornis, from Section Exsertaria. The morphometrics of the two Fergusobia spp. generally overlap, but the structure of the excretory system appears to differ between them, with F. robustae n. sp. lacking the large cells surrounding the duct that occur in F. minimus. The morphology of the infective female differs, with that of F. robustae n. sp. having a more anterior vulva (V 71 –78 vs 80–82% in F. minimus), more slender bodies (diameter 21–29 vs 35–44 µm respectively), and a larger stylet (6.5–9 vs 4–5.5 µm long respectively). Spicule morphology differs between the two species, being angular at 40% of length in F. robustae n. sp. vs 50% in F. minimus. Fergusobia robustae n. sp. and F. colbrani are similar, but collected from hosts of different genera (Eucalyptus vs Angophora) and from different gall forms (TLBG vs spheroid leaf galls). The parthenogenetic female of F. robustae n. sp. cannot be clearly separated from that of F. colbrani, but is more curved in shape when heat-killed, and has a smaller tail volume. In shape, the parthenogenetic female of F. robustae n. sp. is similar to F. brevicauda, F. brittenae, F. cajuputiae, F. curriei, F. cosmophyllae, F. delegatensae, F. diversifoliae, F. fasciculosae, F. floribundae, F. gomphocephalae, F. indica, F. leucoxylonae, F. magna, F. microcarpae, F. minimus, F. morrisae, F. nervosae, F. pimpamensis, F. planchonianae, F. porosae, F. ptychocarpae, F. tumifaciens, F. viminalisae, and F. viridiflorae (Cshape). However, it differs from F. armillarisae, F. camaldulensae, F. dealbatae, F. decorae, F. eugenioidae, F. janetae n. sp., F. leptospermum, F. leucadendrae, F. linariifoliae, F. obliquae n. sp., F. pruinosa e n. sp., F. rileyi, F. rosettae, F, schmidti, and F. sporangae, which have straighter bodies. In length (249–358 µm), the parthenogenetic female of F. robustae n. sp. is smaller than that of F. indica (525–626 µm), F. janetae n. sp. (514–723 µm), and F. magna (418–689 µm), and tends to be smaller than that of F. delegatensae (345–427 µm) and F. floribundae (352– 466 µm). In having cuticle which does not swell when fixed with hot formalin, the female differs from F. jambophila, F. linariifoliae and F. pohutukawa, in which it does. The stylet (6.5–9 µm) of the parthenogenetic female is shorter than in F. camaldulensae (11–13 µm), F. leucoxylonae (9–11 µm) and F. schmidti (11–14 µm). In having enormous oesophageal glands (b’ 1.7–2.7), the female is similar to F. quinquenerviae but lacks the extra lobe or flex found in glands of the latter. In having a body that narrows gradually behind the vulva, is curved and cylindroid in shape, with a bluntly to broadly rounded tail tip, the parthenogenetic female of F. robustae n. sp. differs from that of F. brevicauda, F. cajuputiae, F. curriei, F. dealbatae, F. fisheri, F. gomphocephalae, F. microcarpae, F. nervosae, F. obliquae n. sp., F. porosae, F. pohutukawa, and F. tumifaciens (tail more slender, shape arcuate to straight; or smaller in volume); from F. fasciculosae (tail broader, c’= 1 (0.8–1.3) vs 1.5 (1.1–2.1) in F. robustae n. sp.), and F. philippinensis (truncate tip). In length (12.5–27 µm, mean 18 µm), the tail of female F. robustae n. sp. is usually shorter than in F. tolgaensis (mean 22 µm, range 18–25 µm). The parthenogenetic female lacks the broad opening of the stylet aperture present in F. sporangae. The female is separated from F. juliae in lacking a plate of cuticle that surrounds the vulva in the latter. The female of F. robustae n. sp. is separated from F. diversifolia, F. pauciflorae n. sp. and F. viminalisae on the form of the vulva—being raised or protruding in F. robustae n. sp. vs flat or depressed in the latter species. The circum-oral area of the parthenogenetic female of F. robustae n. sp. is flat, but peaked in F. viminalisae, and the hemizonid is immediately anterior to the pore vs 2–4 annules anterior to it in the latter females. The hemizonid is immediately anterior to the pore in F. robustae n. sp., but 4–5 annules anterior in F. pimpamensis. Using morphological characters only, the parthenogenetic female of F. robustae n. sp. cannot be separated from F. morrisae, F. planchonianae, F. ptychocarpae, or F. viridiflorae. The infective female of F. robustae n. sp. is similar in shape to those of F. fasciculosae, F. gomphocephalae and F. nervosae (open C-shape). It differs from F. eugenioidae, F. juliae, F. morrisae, F. pruinosae n. sp., F. ptychocarpae, F. tumifaciens, and F. viminalisae (J-shape); F. janetae n. sp., F. linariifoliae, F. porosae and F. rileyi (straight); F. armillarisae, F. brevicauda, F. camaldulensae, F. colbrani, F. cosmophyllae, F. cajuputiae, F. decorae, F. fisheri, F. leucoxylonae, F. microcarpae, and F. quinquenerviae (arcuate); and F. magna (less slender; a = 12.2 (10.0–13.3) vs 15.9 (13.8–17.7)). In length (412–521 µm), it is larger than the infective female of F. armillarisae (279–291 µm), F. brevicauda (370 µm), F. cajuputiae (239–309 µm), F. colbrani (369–405 µm), F. dealbatae (307–347 µm), F. decorae (207–256 µm), F. fasciculosae (268–332 µm), F. fisheri (241–395 µm), F. gomphocephalae (222–298 µm), F. leptospermum (376–382 µm), F. leucadendrae (270–291 µm), F. leucoxylonae (252–358 µm), F. linariifoliae (347–384 µm), F. microcarpae (302–341 µm), F. morrisae (322–395 µm), F. nervosae (282 µm), F. philippinensis (290-370 µm), F. planchonianae (303–339 µm), F. porosae (277–300 µm), F. quinquenerviae (259–325 µm), F. rosettae (249–267 µm), F. schmidti (252–395 µm), F. sporangae (289–353 µm), F. tolgaensis (223–272 µm), and F. viridiflorae (321 µm). The infective female of F. robustae n. sp. has a tail 25– 54 µm long, with an almost hemispherical tip, differing from F. magna in which the tail is longer (78–131 µm), from F. pauciflorae n. sp. which has a narrower tip, from F. pruinosae n. sp. which has a notched tip, and from F. obliquae n. sp. which has a sub-cylindroid tail. The female of F. robustae n. sp. lacks the post-anal intestinal sac that is present in F. delegatensae and F. planchonianae. The infective female has a larger stylet than that of F. floribundae and F. minimus (respectively, 7–9 vs 5–8 and 4–5.5 µm), and the stylet tends to be smaller than in F. diversifoliae (9–11 µm). The female differs from F. curriei and F. pimpamensis in tending to have a more anterior vulval opening (V% = 71–78 vs 76–82 and 76–85). The infective female of F. robustae n. sp. is separated from F. brittenae and F. diversifoliae on the position of the hemizonid: 3–4 annules anterior to the excretory pore vs 5 in F. brittenae and 9–11 in F. diversifoliae. In shape (arcuate to J-shaped), the male of F. robustae n. sp. is similar to those of F. brittenae, F. curriei, and F. fasciculosae, and differs from F. pimpamensis (J or C-shape), F. juliae, F. magna, F. planchonianae, F. ptychocarpae, and F. viridiflorae (with strongly curved posterior). With a body length of 348–448 µm, the male is smaller than that of F. magna (446–588 µm) and F. janetae n. sp. (639–750 µm), and larger than that of F. decorae (205–287 µm), F. fasciculosae (274–336 µm), F. gomphocephalae (228–283 µm), F. leucadendrae (254–350 µm), F. leucoxylonae (251–293 µm), F. nervosae (277–312 µm), F. porosae (270–326 µm), F. quinquenerviae (256–329 µm), F. rosettae (246–319 µm), and F. tolgaensis (268–349 µm). In length (6.5–9 µm), the stylet of the male is shorter than in F. camaldulensae (10–13 µm), F. leucoxylonae (10–13 µm), F. pohutukawa (10–11 µm), and F. rileyi (11–13 µm). The male of F. robustae n. sp. has a flattened circum-oral area, differing from that of F. jambophila, F. rosettae, F. sporangae, and F. tolgaensis, in which it is raised. The shape of the tail (arcuate, conoid, with a broadly rounded tip) differs from that of F. philippinensis (truncate tip) and from F. leucadendrae (bluntly rounded tip). The tail of male F. robustae n. sp. tends to be shorter than that of F. dealbatae (23–36 vs 32–50 µm long), and the ratio c’ differs (1.5 (1.2–1.9) vs 2.2 (2–2.7)). Spicule length (17–21 µm) is larger than in F. leucadendrae, F. porosae, and F. viminalisae (respectively, 14–17, 11–16, and 10–15 µm); an

Inconspicuous muscles associated with cloaca. Tail arcuate, ventrally concave, conoid; length 2–2.5 times diameter at cloaca; bluntly rounded tip. Diagnosis and relationships. Fergusobia obliquae n. sp. is morphologically characterized by the combination of a relatively broad, arcuate parthenogenetic female having a small but strongly sclerotised stylet, and a short conoid tail with a bluntly rounded tip; an arcuate infective female with an almost hemispherical tail tip; and a Cshaped male with an arcuate to angular spicule which is not heavily sclerotised and bursa arising 50–80% of body length. Morphologically, F. obliquae n. sp. is similar to F. robustae n. sp., F. pruinosae n. sp., and F. morrisae. It was collected from unilocular LPGs from the host plant E. obliqua (subgenus Eucalyptus, section Eucalyptus), and its associated third instar fly larva lacks a dorsal shield. The species with morphological similarity are from host plants of the subgenus Symphyomyrtus, and were collected from TLBGs or FBGs. Nothing is known of the shield form of the third instar larvae associated with F. pruinosae n. sp., but the fly larva associated with F. robustae n. sp. and F. morrisae had shields with teeth. While DNA sequences are not available for F. obliquae n. sp., the data on host plant associations, gall forms and shield forms of morphologically similar Fergusobia species supports its status as a distinct species. The parthenogenetic female of F. obliquae n. sp. (arcuate shape) differs from that of F. brevicauda, F. brittenae, F. cosmophyllae, F. diversifoliae, F. fasciculosae, F. floribundae, F. gomphocephalae, F. indica, F. leucoxylonae, F. magna, F. microcarpae, F. minimus, F. morrisae, F. pimpamensis, F. planchonianae, F. porosae, F. ptychocarpae, F. schmidti, F. tumifaciens, F. viminalisae, and F. viridiflorae (C-shape). In size (length 294–370 µm), the female of F. obliquae n. sp. is smaller than that of F. indica (525–626 µm), F. janetae n. sp. (514–723 µm) and F. magna (418–689 µm); and larger than that of F. cajuputiae (221–273 µm), F. fasciculosae (237–285 µm) and F. rosettae (228–269 µm). The female tends to be larger than F. leucadendrae (L = 205–303 µm) and F. tumifaciens (L = 224–307 µm). Having a flat circum-oral area separates the parthenogenetic female of F. obliquae n. sp. and those of F. camaldulensae, F. eugenioidae, F. jambophila, and F. tolgaensae, in which it is raised. In addition, the cephalic region is like a flattened dome in the female of F. obliquae n. sp., but in F. dealbatae and F. pruinosae it has straight sides. The stylet (10–12 µm) of the parthenogenetic female is longer than in that of F. curriei (5–8 µm), F. juliae (5–7 µm) and F. minimus (4–8 µm). In having enormous oesophageal glands, the parthenogenetic female of F. obliquae n. sp. is similar to the female of F. quinquenerviae but lacks the extra lobe or flex found in glands of the latter. In having a body that narrows sharply behind the vulva to form a small conoid tail with a broadly rounded tip, the parthenogenetic female is similar to that of F. fisheri, but tends to differ in tail length (20 (15–33) vs 14 (13–16) µm in F. fisheri). The parthenogenetic female also differs from that of F. pohutukawa (conoid tail, with a narrowly rounded tip); F. janetae n. sp., F. indica, F. magna and F. rileyi (longer and more slender tails); and F. armillarisae, F. decorae, F. floribundae, F. leptospermum, F. minimus, F. nervosae, F. pauciflorae n. sp., F. philippinensis, F. sporangae and F. tolgaensis (sub-cylindroid tails). The parthenogenetic female of F. obliquae n. sp. is separated from that of both F. colbrani and F. leucadendrae in having a tail tip that is more narrowly rounded. The female of F. obliquae n. sp. lacks the extensile uterus of F. linariifoliae; and differs from that of F. robustae n. sp. in having a less curved body shape, a broader tail, and flat vs raised vulval lips. The infective female of F. obliquae n. sp. differs in shape (arcuate) from that of F. dealbatae, F. diversifoliae, F. fasciculosae, F. gomphocephalae, F. leucadendrae, F. nervosae, F. pimpamensis, F. philippinensis, F. sporangae, and F. viminalisae (open C-shape); and F. floribundae and F. morrisae (J shape). In length (341–355 µm), the infective female is smaller than that of F. brittenae (375–550 µm), F. cosmophyllae (374–448 µm), F. curriei (417– 489 µm), F. delegatensae (375–452 µm), F. diversifoliae (357–473 µm), F. eugenioidae (438 µm), F. floribundae (357–450 µm), F. juliae (396–550 µm), F. leptospermum (376–382 µm), F. magna (537–633 µm), F. minimus (419–458 µm), F. pimpamensis (369–443 µm), F. ptychocarpae (387–471 µm), F. rileyi (378–433 µm), and F. tumifaciens (354–445 µm); and larger than that of F. armillarisae (279–291 µm), F. cajuputiae (239–309 µm), F. decorae (207–256 µm), F. quinquenerviae (259–325 µm), and F. tolgaensis (223–272 µm). The infective female of F. obliquae n. sp. has a sub-cylindroid tail with a broadly rounded tip, separating it from that of F. camaldulensae, F. curriei, F. delegatensae, F. fisheri, F. floribundae, F. leucoxylonae, F. microcarpae, F. pimpamensis, F. planchonianae, F. robustae n. sp., F. rosettae, and F. schmidti (hemispherical tip); F. pruinosae n. sp. (with notched tip); and F. porosae (bluntly rounded tip). The infective female of F. obliquae n. sp. may have a longer tail than that of F. viridiflorae (n=1) (23 vs 27–30 µm). Similarly, using Siddiqi’s (1994) description, the infective female of F. obliquae n. sp. may be less curved when heat fixed than that of F. brevicauda, and the ratio c’ is smaller in F. brevicauda (1.6–1.8 vs 0.9–1.1), i.e., the tail is relatively broader. The infective female of F. obliquae n. sp. has a relatively narrower tail than that of F. colbrani (c’ 1.6–1.8 vs 0.8–1.2), and a more cylindroid tail than occurs in that of F. linariifolia. It also lacks the raised circum-oral area of the infective female of F. linariifolia. In having an open C-shaped body, the male of F. obliquae n. sp. differs from that of F. brittenae, F. curriei, and F. fasciculosae (J-shape); F. armillarisae, F. colbrani, F. cosmophyllae, F. decorae, F. eugenioidae, F. leucoxylonae, F. linariifoliae, F. microcarpae, F. pauciflorae n. sp., F. rileyi, and F. viminalisae (arcuate); and F. diversifoliae, F. juliae, F. magna, F. planchonianae, F. ptychocarpae, and F. viridiflorae (with strongly curved posterior). In size (length 355–448 µm), the male is smaller than F. janetae n. sp. (639–750 µm) and usually smaller than F. magna (446–588 µm), and larger than F. decorae (205–287 µm), F. gomphocephalae (228–283 µm), F. leucadendrae (254–350 µm), F. leucoxylonae (251–293 µm), F. nervosae (277–312 µm), F. porosae (270–326 µm), F. quinquenerviae (256–329 µm), F. rosettae (246–319 µm), and F. tolgaensis (268–349 µm). The length of the tail in the male of F. obliquae n. sp. is longer than in F. tumifaciens (32–46 vs 18–25 µm). The shape of the tail (arcuate, conoid, with a bluntly rounded tip) differs from that of F. philippinensis (truncate tip) and F. rileyi (slender, straight, with bluntly rounded tip). In having an angular spicule, the male of F. obliquae n. sp. differs from that of F. jambophila and F. pimpamensis, with an arcuate spicule. The spicule form in F. obliquae n. sp. is more slender than in the male of F. pruinosae n. sp., which has a stocky, stout spicule. In the male of F. obliquae n. sp., the bursa arises at 50–80% of body length, separating it from F. brevicauda, F. cosmophyllae, F. decorae, F. fisheri, F. minimus, F. nervosae, F. porosae, F. robustae, F. rosettae, F. sporangae, F. schmidti, and F. tumifaciens, in which the bursa is shorter. Fergusobia obliquae n. sp. is also separated from F. leptospermum, F. linariifoliae, F. pohutukawa, F. rileyi, and F. viridiflorae, in which the bursa is longer. In the male of F. obliquae n. sp. the bursa is smooth, but it is crenate in F. delegatensae. Morphologically, it is difficult to separate males of F. obliquae n. sp. and F. camaldulensae, but it lacks the distinctly peaked head capsule of F. camaldulensae and tends to have a smaller stylet (8.5–11 (mean 9) µm in males of F. obliquae n. sp. vs 10–13 (mean 12) in F. camaldulensae). The head capsule of male F. obliquae n. sp. is slightly raised vs flat in male F. morrisae, but otherwise it is difficult to separate them. Etymology. Named after Eucalyptus obliqua, the plant species from which the nematodes were collected.

Orifice of dorsal pharyngeal gland often obscure, ~1 µm posterior to stylet knobs. Anterior fusiform part of digestive tract little expanded, occupying 41–58% of body diameter, length 3.6 (2.7–4.5) times diameter. Pharyngeal glands relatively small, extending over intestine, occupying 59 (56–65)% body diameter, distance from head to posterior end of glands being 32 (26–38)% of total body length. Position of secretory/excretory pore opening variable, from close to nerve ring to posterior to nucleus of pharyngeal glands; duct obscure. Hemizonid just anterior to pore.

Inconspicuous muscles associated with cloaca. Tail arcuate, ventrally concave, conoid; length 1–2.5 times diameter at cloaca; broadly rounded tip (Fig. 4L). Diagnosis and relationships. Fergusobia pauciflorae n. sp. is morphologically characterized by the combination of a medium sized, arcuate, parthenogenetic female with a small stylet, and a conoid tail with a bluntly rounded tip; a small, open C to J-shaped infective female with a broadly rounded to almost hemispherical tail tip; and a straight to arcuate male with a stout, angular spicule and bursa at ~70% of body length. Morphologically, F. pauciflorae n. sp. is similar to F. brittenae, F. fasciculosae, F. minimus, F. morrisae, F. planchonianae, F. pruinosae n. sp., F. ptychocarpae, F. robustae n. sp., and F. sporangae. It was collected from FBGs on E. pauciflora (Eucalyptus, section Cineraceae), while the other nematodes named above were respectively collected from TLBGs, style galls, FBGs, ‘leafy’ LBGs, FBGs, FBGs, FBGs, and UABGs. All these FBGers and the TLBGers and UABGers came from host plants of the subgenus Symphyomyrtus, with F. ptychocarpae collected from Corymbia, i.e., from hosts that are clearly genetically different from that of F. pauciflorae n. sp. Only the host plant E. planchoniana is also from subgenus Eucalyptus. The third instar fly larvae associated with F. pauciflorae n. sp. had dorsal shields of the ‘bars of spicules’ form, differing from all but those with F. planchonianae. This non-morphological evidence supports the status of F. pauciflorae n. sp. as a true species. Morphologically, it differs from F. planchonianae in that the respective parthenogenetic females have differing shapes for the head capsule, and F. pauciflorae n. sp. has a longer tail (24 (14–32) vs 14 (11–16) µm). Infective females of F. pauciflorae n. sp. lack the post-anal sac of the intestine that is present in F. planchonianae . Males of F. pauciflorae n. sp. have a broader tail tip than F. planchonianae, and the form of the bursa differs, being smooth in the former but longer and with a crenate edge in the anterior part in the latter. The parthenogenetic female of F. pauciflorae n. sp. (C-shape) differs from that of F. armillarisae, F. decorae and F. obliquae n. sp. (arcuate to open C-shaped); and from F. janetae n. sp., F. linariifolia and F. rileyi (straight or arcuate). In length (309–393 µm), the female is larger than that of F. decorae (205–302 µm), F. fasciculosae (237– 285 µm), F. fisheri (228–305 µm), F. leucadendrae (205–303 µm), F. nervosae (245–309 µm), F. rosettae (228–269 µm), and F. tumifaciens (224–307 µm); and smaller than F. indica (525–626 µm), F. magna (418–689 µm) and F. janetae n. sp. ( 514–723 µm). In having a non-extensile uterus, the female differs from F. armillarisae, F. brevicauda, F. camaldulensae, F. jambophila, F. linariifolia, F. magna, F. rileyi, and F. tolgaensis, in which it is extensile. In having cuticle which does not swell upon fixation; the parthenogenetic female of F. pauciflorae n. sp. differs from that of F. armillarisae, F. decorae, F. pohutukawa, and F. viridiflorae in which it does. Having a flat circum-oral area separates the parthenogenetic female of F. pauciflorae n. sp. and those of F. camaldulensae and F. jambophila, in which it is raised. The stylet (9–11 µm) is longer than in F. curriei (5–8 µm), F. floribundae (6–7 µm), F. juliae (5–7 µm), and F. minimus (4–8 µm), and tends to be larger than in F. philippinensis (7.5–9 µm) and F. pimpamensis (7–9 µm). In having large oesophageal glands, the parthenogenetic female of F. pauciflorae n. sp. is similar to that of F. quinquenerviae but lacks the extra lobe or flex found in glands of the latter. In having a body that narrows gradually behind the vulva, is curved and conoid in shape, with a bluntly rounded tail tip, the female differs from F. pohutukawa (straighter, with a narrowly rounded tip); F. indica, F. janetae n. sp., F. magna and F. rileyi (more slender, arcuate to straight); F. porosae (tail with smaller volume); F. leucoxylonae and F. obliquae (sub-triangular tail); F. brevicauda, F. cajuputiae, F. colbrani, F. curriei, F. fasciculosae, F. fisheri, F. gomphocephalae, F. juliae, F. leucadendrae, F. linariifolia, F. magna, F. microcarpae, F. quinquenerviae, F. rosettae, F. schmidti, F. sporangae, F. tumifaciens, F. viminalisae, and F. viridiflorae (broader, usually shorter tails); and F. planchonianae (with a shorter tail). The parthenogenetic female of F. pauciflorae n. sp. has the hemizonid opening immediately adjacent to the secretory/excretory pore or 2 annules anterior to it, separating it from F. brittenae, F. cosmophyllae, F. dealbatae, F. delegatensae, F. diversifoliae, and F. pruinosa (respectively, 8–9, 4–5, 4–6, 5, 8, and 5–6 annules anterior to the pore). The morphometrics of the parthenogenetic female of F. pauciflorae n. sp. overlap with those of F. eugenioidae, F. morrisae, F. pimpamensis, F. leucoxylonae, F. leptospermum, and F. robustae n. sp. The female can be separated from F. eugenioidae by the position of the secretory/excretory pore (80–105 vs 64–85 µm posterior to the anterior end in the latter); from F. morrisae by the shape of the cephalic capsule (flat vs peaked); from F. robustae n. sp. by the form of the vulval lips (flat vs raised); and from F. leptospermum in intestinal structure (lacking vs with a clear lining); and from F. pimpamensis by body diameter (31 (25–36 µm) vs 41 (36–46 µm)). Morphologically, it is not possible to separate this stage from that of F. ptychocarpae. The body of the infective female of F. pauciflorae n. sp. (open C to J) differs in shape from that of F. armillarisae, F. camaldulensae, F. colbrani. F. cosmophyllae, F. dealbatae, F. decorae, F. diversifoliae, F. fasciculosae, F. gomphocephalae, F. leucadendrae, F. linariifolia, F. nervosae, F. obliquae n. sp., F. pimpamensis, F. philippinensis, F. sporangae, F. tolgaensis, and F. viminalisae (straight to arcuate). In length (309–393 µm), the infective female is smaller than that of F. curriei, F. eugenioidae, F. janetae n. sp., F. juliae, F. magna, and F. minimus; tends to be smaller than that of F. brittenae (375–550 µm), F. cosmophyllae (374–448 µm), and F. ptychocarpae (387–471 µm); and is larger than that of F. armillarisae (279–291 µm), F. cajuputiae (239–309 µm), F. decorae (207–256 µm), F. gomphocephalae (222–291 µm), F. leucadendrae (227–291 µm), F. nervosae (282 µm), F. quinquenerviae (259–325 µm), F. porosae (277–300 µm), and F. tolgaensis (223–272 µm). The stylet (8– 10 µm) is longer than in F. colbrani (8.5 µm) and F. minimus (4–5.5 µm), and smaller than that of F. leptospermum (11 µm). The infective female has a shorter tail (20–32 µm) than that of F. janetae n. sp. (91 µm), F. leptospermum (34–38 µm), F. magna (78–131 µm) and F. rileyi (40–50 µm). The female has a sub-cylindroid tail with a broadly rounded tip, separating them from the infective female of F. porosae (tail tip bluntly rounded); from F. gomphocephalae and F. pruinosae n. sp. (notched tip); from F. philippinensis (truncate tip); and from F. curriei, F. delegatensis, F. fisheri, F. floribundae, F. leucoxylonae, F. microcarpae, F. planchonianae, F. robustae n. sp., F. rosettae, F. schmidti, and F. pimpamensis (broad, hemispherical tip). The sub-cylindroid tail form also separates the infective female of F. pauciflorae n. sp. from that of F. brevicauda and F. viridiflorae (tail more cylindroid), and from F. tumifaciens which has a relatively broader tail (c’ 1.2–2.3 vs 0.7–1.2 in F. tumifaciens). Infective females of F. pauciflorae n. sp. and F. morrisae cannot be separated morphologically. In shape (straight to arcuate), the male of F. pauciflorae n. sp. differs from that of F. brittenae, F. curriei, and F. fasciculosae (J-shape), F. pimpamensis (J or C-shape), F. diversifoliae, F. juliae, F. magna, F. planchonianae, F. ptychocarpae, and F. viridiflorae (with strongly curved posterior). In having a flat circum-oral area, the male is separated from that of F. camaldulensae, F. jambophila, and F. tolgaensis, in which it is raised. The length of the tail in the male of F. pauciflorae n. sp. (23–46 µm) is shorter than in F. janetae n. sp. (82–111 µm), F. magna (54– 87 µm), F. pohutukawa (50–61 µm), and F. rileyi (58–70 µm), and tends to be shorter than that of F. leptospermum (43–57 µm). The shape of the tail (arcuate with a broadly rounded tip) differs from that of F. philippinensis (truncate tip), F. rileyi (slender, straight, with bluntly rounded tip) and from F. leucadendrae (bluntly rounded tip). In having an angular spicule, F. pauciflorae n. sp. differs from F. armillarisae and F. rosettae, in which it is arcuate. The spicule is stout in form, differing from those in F. obliquae n. sp., F. pruinosae n. sp., and F. janetae n. sp., in which they are slimmer. In F. pauciflorae n. sp., the manubrium of the spicule is not offset, but it is offset in F. cajuputiae. In the male of F. pauciflorae n. sp., the bursa arises at ~ 70% of body length, separating it from that of F. brevicauda, F. colbrani, F. cosmophyllae, F. dealbatae, F. decorae, F. eugenioidae, F. fisheri, F. floribundae, F. gomphocephalae, F. jambophila, F. juliae, F. microcarpa, F. minimus, F. nervosae, F. schmidti, F. porosae, F. quinquenerviae, F. robustae n. sp., F. rosettae, F. schmidti, F. sporangae, F. tolgaensis, F. tumifaciens, and F. viminalisae, in which the bursa is shorter; and F. janetae n. sp., F. leptospermum, F. linariifoliae, F. pohutukawa, F. rileyi, and F. viridiflorae in which it is longer. The bursa of F. pauciflorae n. sp. is smooth, but it is crenate in F. delegatensae. Morphometrically, males of F. pauciflorae n. sp. and F. morrisae overlap, but in F. pauciflorae n. sp. the secretory/excretory pore does not open onto an area of raised cuticle as in F. morrisae.

Tail straight to ventrally arcuate, sub-conoid, ~3���5 times as long as diameter at cloaca, narrowing gradually to bluntly rounded or angular tip (Fig. 1J). Diagnosis and relationships. Fergusobia janetae n. sp. is morphologically characterized by the combination of a large, almost straight, spindle-shaped parthenogenetic female with an extensile uterus and a narrow conoid tail; an arcuate, relatively broad, infective female with a conoid tail having a narrowly rounded tip; and an open Cshaped male with an arcuate to angular spicule and bursa arising near the level of the stylet knobs. Morphologically, F. janetae n. sp. is most similar to F. magna Siddiqi 1986 sensu Davies 2010 (in Davies et al. 2010b), F. indica (Jairajpuri, 1962) Siddiqi, 1986 and F. rileyi, and also has similarities with F. linariifolia Davies 2014 (in Davies et al. 2014e) and F. pohutukawa Davies 2007 (in Taylor et al. 2007). Its status as a distinct species is corroborated by molecular data from sequencing of the relatively conserved 18S and 28S D2/D3 expansion segment. The parthenogenetic female of F. janetae n. sp. (a straight or arcuate spindle-shape when heat-fixed, with a long slender tail) differs from all described species of Fergusobia, except F. magna. Body length of the parthenogenetic female of F. janetae n. sp. overlaps with that of F. magna and F. indica (respectively, 514���723 vs 418���780 and 525���626 ��m) and is larger than all other described species of Fergusobia. However, its straight to arcuate body separates female F. janetae n. sp. from F. magna which has a C-shaped parthenogenetic female. The presence of an extensile uterus in the parthenogenetic female of F. janetae n. sp. separates it from F. indica and also from F. cajuputiae Davies & Giblin-Davis, 2004, F. colbrani Davies 2014 (in Davies et al. 2014a), F. dealbatae Davies & Giblin-Davis, 2004, F. delegatensae Davies 2013 (in Davies et al. 2013b), F. eugenioidae Davies 2012 (in Davies et al. 2012b), F. fisheri Davies & Lloyd, 1996, F. leucadendrae Davies & Giblin-Davis, 2004, F. nervosa Davies & Giblin-Davis, 2004, F. philippinensis Siddiqi, 1994, F. schmidti Davies 2014 (in Davies et al. 2014c), F. quinquenerviae Davies & Giblin-Davis, 2004, F. rosettae Davies 2014 (in Davies et al. 2014d), F. rileyi Davies 2012 (in Davies et al. 2012a), F. sporangae Davies 2014 (in Davies et al. 2014d), F. tolgaensis Davies 2014 (in Davies et al. 2014d), F. tumifaciens (Currie 1937) Wachek 1955 sensu Davies 2014 (in Davies et al. 2014b), and F. decorae Davies 2014 (in Davies et al. 2014e), which lack extensile uteri. In having cuticle that does not swell upon fixation; it differs from F. linariifoliae and F. pohutukawa, and also from F. jambophila Siddiqi 1986, in which it does. Fergusobia janetae n. sp. is separated from F. rileyi by both body length and in having a longer tail (90 vs 40���50 ��m). The only infective female of F. janetae n. sp. available for examination was moulting, and information about it is therefore limited. Its body length and stylet length are unlikely to accurately reflect that of mature individuals, i.e., cannot be used here as characters. Its arcuate shape differs from that of F. diversifoliae, F. fasciculosae Davies 2012 (in Davies et al. 2012b), F. gomphocephalae Davies 2014 (in Davies et al. 2014c), F. leucadendrae, F. nervosae, F. pimpamensis Davies 2013 (Davies et al. 2013b), F. philippinensis, F. rosettae, F. sporangae, F. tolgaensis Davies 2014 (in Davies et al. 2014c), and F. viminalisae Davies 2014 (in Davies et al. 2014b) (open Cshape), and from F. eugenioidae, F. juliae Davies 2012 (in Davies et al. 2012b), F. morrisae Davies 2012 (in Davies et al. 2012b), F. pruinosae n. sp., F. ptychocarpae Davies 2008 (in Taylor & Davies 2008), F. tumifaciens, and F. viminalisae (J-shaped). It has a straight slender sub-conoid tail with a bluntly rounded tip, separating it from F. brittenae Davies 2010 (in Taylor & Davies 2010), F. cajuputiae, F. curriei Fisher & Nickle 1968, F. leptospermum Davies 2017 (in Davies et al. 2017), F. leucadendrae, F. minimus Lisnawita (in Davies et al., 2013b), F. nervosae, F. pauciflorae n. sp., F. quinquenerviae, F. tolgaensis (with broadly rounded tips); F. eugenioidae, F. juliae, F. linariifoliae, F. morrisae, F. porosae Davies 2013 (in Davies et al. 2013a), F. pruinosae n. sp., F. ptychocarpae, F. tumifaciens, F. viminalisae, F. viridiflorae Davies & Giblin-Davis 2004 (with J���shaped tails); F. armillarisae Davies 2014 (in Davies et al. 2014), F. brevicauda Siddiqi 1994, F. camaldulensae, F. colbrani, F. cosmophyllae Davies 2013 (in Davies et al. 2013b), F. dealbatae, F. decorae, F. delegatensae, F. diversifoliae Davies 2013 (in Davies et al. 2013b), F. fasciculosae, F. fisheri, F. floribundae Davies 2013 (in Davies et al. 2013b), F. gomphocephalae, F. leucoxylonae Davies 2014 (in Davies et al. 2014c), F. microcarpae Davies 2013 (in Davies et al. 2013a), F. obliquae n. sp., F. pimpamensis, F. planchonianae Davies 2014 (in Davies et al. 2014b), F. robustae n. sp., F. rosettae, F. schmidti, F. sporangae (with sub-hemispherical tips); and from F. philippinensis (with a truncate tip). The infective female of F. janetae n. sp. has a more posterior vulva than that of F. magna (V% 65���72 vs 51���62). In length (639���750 ��m), the male of F. janetae n. sp. is larger than all described species of Fergusobia. The shape of the tail (slender, arcuate with a bluntly rounded tip, long) is similar to that of F. magna and F. rileyi, but differs in being longer (82���111 vs 54���87 and 58���70 ��m, respectively) and is slimmer than in F. magna (respectively, c��� ratio 3.3���4.8 vs 2.0���3.3). In length (9���11 ��m), the stylet is similar to that of most described species, but longer than in F. minimus (4���7 ��m). Spicule length (23���27 ��m) is smaller than in F. magna (30���36 ��m); but overlaps with or is longer than in other described species of Fergusobia. The shape of the spicules in F. janetae n. sp. (more or less angular) differs from those of F. jambophila, F. pimpamensis, F. rosettae, and F. decorae, in which it is clearly arcuate. In the male of F. janetae n. sp., the bursa extends over>90% of the body length, longer than in most Fergusobia spp., except for F. leptospermum (99%), F. linariifolia (90%), F. pohutukawa (99%), F. rileyi (90���95%) and F. viridiflorae (90%).

Structure. Measurements as in Tables 4���8. Body narrow, elongate (Figs 71���74). Head (Figs 75���76); vertex with prominent medial suture, deeply sunk in vicinity of fovea; genal processes short, 0.33���0.42 times as long as vertex; antenna short, 0.78���0.89 times width of head, with a single subapical rhinarium on each of segments 4, 6, 8 and 9; segment 10 with a long bluntly rounded seta and a short bluntly rounded seta. Fore wing (Figs 77���78) 4.51��� 5.36 times as long as head width, 2.70���3.17 times as long as wide, elongate with slightly pointed apex; vein Rs straight, slightly upturned distally, terminating well short of wing apex, considerably shorter than vein M, RsM: 0.73���0.82; medial cell smaller than cubital cell; veins M 1 + 2 and M 3 + 4 short, broadly diverging with corresponding low m 1 cell value: 1.28���1.53; veins Cu 1 a long, arched and Cu 1 b long, each widely divergent with corresponding low cu 1 cell value: 1.23���1.60; metatibia 1.07���1.13 times as long as width of head, considerably longer than metafemur, with 2 inner and 1 outer small, sclerotised apical spurs.

Comments. Myotrioza insularis sp. nov. can be distinguished by the following unique combination of characters: habitus as in Figs 71���74, antenna with normal arrangement of rhinaria, fore wing elongate with rounded apex, Rs considerably shorter than vein M (Figs 77���78), female proctiger short with field of weakly hooked setae, rounded profile without terminal upward inflection, valvula ventralis curved, ventral profile of female subgenital plate curved (Fig. 90), male proctiger conoid with lateral lobe, aedeagus short, paramere broadly ovate with rounded apex (Figs 85���86). Myotrioza insularis sp. nov. is most closely related to M. clementsiana sp. nov. (COI sequence divergence 7.4���8.1 %) (Table 1). They differ from all other species of Myotrioza gen. nov. by their elongate habitus and general pale yellow brown colouration with abdominal membrane colouration green. M. insularis sp. nov. differs from M. clementsiana sp. nov. in its larger body size, it occurs on M. insulare rather than M. platycarpum and has a coastal rather than an inland, eremean distribution. Within M. insularis sp. nov., sequence divergence of Kangaroo Island material from the proximal localities on Fleurieu, Yorke and Eyre Peninsulas on the South Australian mainland may be explained by genetic divergence by distance, separated by biogeographic barriers and consequential disjunct host populations (Fig. 1). Etymology. Named after L. insularis, referring to an island. Host-plant association and distribution. (Tables 2���3). Myotrioza insularis sp. nov. is recorded from Myoporum insulare R.Br. (Boobialla) on Kangaroo Island, southern Yorke Peninsula and southern Eyre Peninsula, and on an ornamental tree in suburban Adelaide on mainland South Australia. It is one of 10 species of Myotrioza gen. nov. and 24 species of Triozidae recorded for South Australia. It is considered endemic to that state, although it is likely to occupy a broad distribution given that its host is widely distributed in coastal southern Australia. It is one of 2 species of Myotrioza gen. nov., namely M. insularis sp. nov. and M. markmitchelli sp. nov. from M. insulare. Myoporum insulare is a shrub or small tree to 6 m high. It occurs commonly in sandy coastal heath in WA, SA, NSW, Vic, Tas (Chinnock 2014). Its record from Beyeria lechenaulti is considered doubtful, being more likely to be vagrant from nearby plants., Published as part of Taylor, Gary S., Fagan-Jeffries, Erinn P. & Austin, Andy D., 2016, A new genus and twenty new species of Australian jumping plant-lice (Psylloidea: Triozidae) from Eremophila and Myoporum (Scrophulariaceae: Myoporeae), pp. 1-84 in Zootaxa 4073 (1) on pages 45-49, DOI: 10.11646/zootaxa.4073.1.1, http://zenodo.org/record/270709, {"references":["Taylor, G.

Male: [specimens in ethanol] Pale yellow brown: vertex with indistinct pale orange brown marking in vicinity of fovea; eyes greyish brown; antennal segments 8���10 progressively dark brown; mesopraescutum with a pair of pale orange brown anterior submedial markings; mesoscutum with a narrow medial and two pairs of pale orange brown submedial markings; fore wings with brown infuscation; hind wings clear; fore wing veins equally pigmented brown; legs pale yellow-brown; abdominal tergites 1���5 with greyish infuscation; abdominal membrane colouration pale green; proctiger, subgenital plate and parameres yellow-brown; basal portion of proctiger and apices of parameres black. Female: [specimens in ethanol] as for male except generally darker with more prominent markings; head and thorax with pale green suffusion; abdominal membrane colouration darker green; abdominal tergites and sternites with brown transverse bands, proctiger and subgenital plate pale yellow-brown with a brown to dark brown marking anteriolaterally and apices dark brown to black. Structure. Measurements as in Tables 4���8. Body short, compact (Figs 189���192). Head (Figs 193���194); vertex with weak medial suture, little sunk in vicinity of fovea; genal processes short, 0.24���0.32 times as long as vertex; antenna very short, 0.52���0.67 times width of head, with a single subapical rhinarium on each of segments 4, 6, 8 and 9; segment 10 with a very short bluntly rounded seta and a minute bluntly rounded seta. Fore wing (Figs 195��� 196) 3.35���3.85 times as long as head width, 2.45 ���3.00 times as long as wide, short, broad with rounded apex; vein Rs straight, slightly upturned distally, terminating well short of wing apex, little shorter than vein M, RsM: 0.73��� 0.80; medial cell short, a little shorter than cubital cell; vein Rs short, straight, slightly upturned distally, terminating well short of wing apex; vein M longer than Rs; medial and cubital cells subequal; veins M 1 + 2 and M 3 + 4 short, broadly diverging with corresponding low m 1 cell value: 1.32���1.59; veins Cu 1 a short, arched and Cu 1 b short, each widely divergent with corresponding low cu 1 cell value: 0.73���0.97; metatibia 0.57���0.70 times as long as width of head, similar length to metafemur, without sclerotised apical spurs. Male terminalia (Figs 213���214); proctiger distinctly triangular, narrow basally, with expanded lateral lobes bearing a prominent row of long equidistant setae on dorsoposterior margin; subgenital plate broadly rounded; parameres (Fig. 214) very long, narrow, acicular, evenly tapering to incurved sclerotised apices; distal portion of aedeagus long, with asymmetrical apical expansion (Fig. 213). Female terminalia (Fig. 220): proctiger long, elongate triangular, posterior margin with a subterminal lobe from lateral aspect and with sclerotised apex; subgenital plate elongate triangular with tapering sclerotised apex; distal portion of proctiger with a few long pale setae and subgenital plate with sparse short setae. Comments. Myotrioza scopariae sp. nov. can be distinguished by the following unique combination of characters: habitus as in Figs 189���192, antenna with normal arrangement of rhinaria, fore wing broad with rounded apex, Rs little shorter than vein M (Figs 195���196), female proctiger with sparse setae, dorsoposterior margin with weak subapical lobe and terminal pointed inflection, valvula ventralis elongate, curved, subgenital plate pointed, ventral profile of female subgenital plate curved (Fig. 220), male proctiger triangular with long setae along dorsoposterior margin, aedeagus elongate, paramere elongate, pointed without anterior subapical lobe (Figs 213��� 214). For diagnosis from closely related species, see Comments for M. interstantis sp. nov. Etymology. Named after Eremophila scoparia, the host species. Host-plant association and distribution. (Tables 2���3). Myotrioza scopariae sp. nov. is recorded from Eremophila scoparia at Credo Station near Coolgardie and near Norseman, Western Australia, and in the Gawler Ranges in South Australia. As these are widely separated localities it is likely to occupy the vast majority of its hosts range in eremean southern Australia. It is likely to occupy a broad distribution given that it occurs on multiple hosts that are widely distributed in southern Australia. It is one of 11 species of Myotrioza gen. nov. and 17 species of Triozidae recorded for Western Australia and one of 10 species of Myotrioza gen. nov. and 24 species of Triozidae recorded for South Australia. It is one of 4 species of Myotrioza, namely M. darwinensis sp. nov., M. eremophili sp. n, M. oppositifoliae sp. nov. and M. scopariae sp. nov. from E. oppositifolia; and one of 3, namely M. eremophili sp. nov., M. gawlerensis sp. nov. and M. scopariae sp. nov. from E. scoparia. For distribution of M. oppositifolia, refer to M. darwinensis sp. nov. and for E. scoparia refer to M. eremophili sp. nov. Its record from Casuarina pauper is considered doubtful, being more likely to be collected from nearby plants., Published as part of Taylor, Gary S., Fagan-Jeffries, Erinn P. & Austin, Andy D., 2016, A new genus and twenty new species of Australian jumping plant-lice (Psylloidea: Triozidae) from Eremophila and Myoporum (Scrophulariaceae: Myoporeae), pp. 1-84 in Zootaxa 4073 (1) on pages 72-73, DOI: 10.11646/zootaxa.4073.1.1, http://zenodo.org/record/270709
