This species has been collected from several localities in Tasmania (Fig. 56). Biology. Aulacus bashfordi has been reared from eucalyptus infested with Epithora dorsalis (Macleay) (Cerambycidae) or emerged from eucalyptus infested with Epithora dorsalis and Coptocercus rubripres (Cerambycidae). Comments. Aulacus bashfordi is in a group together with A. aquilus, A. froggatti and A. pallidicaudis, all of which have the mesosoma rounded antero-laterally in lateral view, metasoma ovate, and lack an ovipositor guide on the hind coxae. Aulacus bashfordi and A. froggatti both lack the lateral medial carina above the toruli that is present in the other two species. Aulacus bashfordi and A. froggatti can be separated by both sculpturing and colour differences. Aulacus bashfordi has a largely black body and rugose face whereas A. froggatti is a largely brown species and has a punctate-reticulate face (see key for additional colour differences)., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 20-22, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367

This species is named after the Frederick Parkhurst Dodd, entomologist and collector. Distribution. This species is known from two widely separated localities in Queensland (Fig. 58). Biology. Nothing is known of the biology of this species. Comments. Although A. doddi keys out with A. quickei sp., the two species are readily separated by the characters in the key. Aulacus doddi is readily distinguished from all other Australian species by the distinctive cream band dorso-laterally on metasomal T2 (Figs 17A, B). The specimen from Brisbane, Queensland, has somewhat smaller eyes (about 15% less in length) when compared with the specimens from Kuranda, Queensland. This difference is possibly intra-specific variation but as further specimens are collected, it may prove to belong to a separate species. Also, the various cream coloured areas of the Brisbane specimen are distinctly cream whereas this colouration has darkened in the other specimens. This is probably an artifact, possibly due to the age of the specimens., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 35-37, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367

Aulacus albimanus is known from two widely separated localities, Mackay, Queensland and Uralla, NSW (Fig. 55). Biology. The male specimen from Uralla, NSW is labelled as a parasite of Coptocercus rubripes (Boisduval) (Coleoptera: Cerambycidae: Phoracanthini). Comments. Kieffer (1911) originally described A. nigriventris as a variety of A. albimanus, although they were later separated into two species (Smith 2001). Although the whereabouts of the holotype of A. nigriventris is in question, we believe that the male specimen in the BMNH is the holotype as it is clearly labelled in Kieffer's handwriting as " Aulacinus albimanus var. nigriventris ". There is also a separate typed label "Determined by Dr. Kieffer". The type specimens of Aulacus albimanus and A. nigriventris are similar in both general colouration and sculpturing, differing only in the colouration of the scape and pedicel which are orange in the former species and black in the latter species. Given this is the only distinguishing feature between the two specimenss, we hereby synonymise the two names. Aulacus albimanus keys out with A. burnsi, but the face is rugose (rugulose in A. burnsi), ovipositor guide somewhat caudal (medial in A. burnsi), and body black except femora, tibiae and posterior T1 orange (body black except propleuron and ventral half of pronotum orange in A. burnsi)., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 10-11, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367, {"references":["Kieffer, J. - J.

Etymology. This species is named after the type locality, Kiwarrak State Forest, south of Taree, NSW. Distribution. This species is known only from the type locality (Fig. 61). Biology. All specimens emerged from the dead branch of grey myrtle, Backhousia myrtifolia (Myrtaceae) infested with Pseudanilara and Chrysobothris (Buprestidae). Comments. Aulacus kiwarrakensis is identifiable by the combination of characters in the key, viz., mesosoma angular in lateral view, metasoma ovate, brown spot apically on fore wing, hind wing venation incomplete. All of these characters are shared with both A. leai and A. walkeri, but A. walkeri can be readily separated from the other two species because it has a much longer hind tarsal claw, 3.0�� length of tarsomere 5. Aulacus kiwarrakensis also has a rugose face but differs from A. leai, which has a punctate-rugose face.

Biology. Nothing is known of the biology of this species. Comments. Aulacus froggatti is in a group together with A. aquilus, A. bashfordi and A. pallidicaudis, all of which have the mesosoma rounded antero-laterally in lateral view, metasoma ovate, and lack an ovipositor guide on the hind coxae. It can be readily distinguished from A. bashfordi, both of which lack a lateral medial carina above the toruli, by both sculpturing and colour differences. Aulacus froggatti is a largely brown species and has a punctate-reticulate face whereas Aulacus bashfordi has a largely black body and rugose face (see key for additional colour differences).

Townes 1950: 113) Diagnosis of Aulacus based on Australian species. Head usually without occipital carina (very rarely present laterally, if so, weak (narrow)); frons with or without a transverse carina above antennal sockets; 14 antennomeres in female, 13 antennomeres in male; scape usually strongly convex in lateral view, much thicker than pedicel and flagellomeres; antennal insertions low on face, near lower margin of eyes; eyes circular or subcircular, remote from the mandibles; pronotum without angular process; metapostnotum present between propodeum and metanotum as a distinct sclerotisation; propodeum pyramidal, metasoma inserted high on the apex (e.g., Fig. 16G); first metasomal tergite (T1) and second tergite (T2) fused dorsally, forming a petiole (e.g., Figs 19H, 38H); hind coxa with (e.g., Figs 2F, 30F) or without a groove (e.g., Fig. 15F) or notch on inner ventral surface, the apposed grooves or notches forming an ovipositor guide; hind trochanter with a transverse trochanteral groove (e.g., Fig. 5D); prefemur (trochantellus) present; each tarsal claw with one basal tooth (sometimes difficult to see); fore wings not plicate at rest; fore wing vein 2-Rs+M generally long, second discal cell elongate, vein 2m-cu present, vein 2r-m often absent, largely spectral when present, vein 3r-m present, often largely spectral (see Fig. 1); ovipositor exserted, protruding well beyond apex of metasoma. Comments. Aulacus was first proposed as a genus by Jurine (1801) but was a nomen nudum because no species were included. In 1807, Jurine rectified this by describing Aulacus striatus. Early authors, however, did not define the generic limits of Aulacus, so a number of genera were erected without due consideration of interspecific variation. This resulted in a proliferation of new genera: Disaulacinus Kieffer, Disphaeron Dahlbom and Micraulacinus Kieffer from Australia, Neuraulacinus Kieffer from Australia and South America, Parafoenus Kieffer from South America, and Pycnaulacus Cushman from the USA. By 1912, Kieffer had recognised some 41 species in six genera as well as the subgenus Aulacinus Westwood. Of these, 17 species were Australian. Although Kieffer (1902) had synonymised Pammegischia Provancher with Aulacus, the mainly North American Pammegischia were not transferred to Aulacus until much later (Townes 1938). In his 1939 catalog, Hedicke synonymised Disphaeron and included a number of additional species in the other genera. Townes (1950) evaluated various characters, particularly wing venation, and in the process defined the generic limits of Aulacus, leading him to synonymise Aulacinus, Micraulacinus, Neuraulacinus, Parafoenus, and Pycnaulacus with Aulacus. However, Townes erroneously synonymised Disaulacinus with Aulacostethus Philippi (now Pristaulacus Kieffer). Disaulacinus was later synonymised with Aulacus by Crosskey (1953). Since Crosskey (1953), the classification has remained stable. Smith (2001) provided a world catalog of Aulacidae, including 18 Australian species. Jennings & Austin (2004a, b) added six new Aulacus species from South Australia and Western Australia (see also checklist of Australian species in Jennings 2010 & Turrisi 2017). Based on morphological analyses, Turrisi et al. (2009) found Aulacus to be paraphyletic. However, this needs to be confirmed by a comprehensive global phylogenetic analysis. As there have not been any further attempts to examine species relationships, here we continue to place the Australian aulacid taxa with simple hind tarsal claws (i.e. not pectinate) in Aulacus (see Jennings et al. 2004a)., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 6-7, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367, {"references":["Jurine, L.

MALE. Unknown. Etymology. We have named this new species from confusio, Latin for confused, referring to the misidentification of the specimen in OUMNH. Distribution. This species is known from the type locality Port Phillip, Victoria (Fig. 58). Biology. Nothing is known of the biology of this species. Comments. The specimen in OUMNH has a locality label of Port Phillip [Victoria, Australia] and a separate identification label “ A. signatus Shk. ” It is not known who placed the identification label on the pin, but it is clearly a very old label. Pristaulacus signatus (Shuckard, 1841) was originally described (as Aulacus signatus) from Ceylon [Sri Lanka] (see also Smith 2001, p. 297). However, this specimen clearly belongs to Aulacus as it has, inter alia, non-pectinate hind claws. Two species, A. confusus and A. mareebaensis, both share the following: mesoscutum angular in lateral view, medial carina above the toruli lacking, metasoma ovate, ovipositor guide on hind coxa oblique and medial, and fore wing with brown infuscation apically on the marginal and third submarginal cells. They can be readily distinguished by the ovipositor being longer than the body in A. confusus and ovipositor shorter than the body in A. mareebaensis (see key for further details).

The holotype and most of the paratypes were collected from Tamborine Mountain, south-east Queensland (Fig. 60). Biology. Nothing is known of the biology of this species. Comments. Aulacus hackeri keys out with A. neboissi, both species having the mesoscutum angular in lateral view, metanotum clavate, brown infuscation apically on the fore wing (although less distinct or sometimes absent on the former species), and a transverse ovipositor guide on the hind coxa. The two species, however, differ in a number of characters: ovipositor guide medial, frons with lateral medial carina above toruli, and largely blackbrown colouration in A. hacker, whereas in A. neboissi, the ovipositor guide is distal, the frons lacks a lateral medial carina above the toruli, and the head is black, and the meso- and metasoma orange. The specimen from Brisbane lacks the brown infuscation apically on the marginal and third submarginal cells of fore wings and for this reason has not been included in the type series., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 48-50, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367

Distribution. This species is known only from the holotype locality (Fig. 56). Biology. Nothing is known of the biology of this species. Comments. Turrisi et al. (2009) suggested that amongst several diagnostic characters, Aulacus (worldwide) lack an occipital carina, which is present in Pristaulacus. However, two species from Australia, A. bamagensis and A. grossi (coded correctly in Turrisi et al. (2009) as having an occipital carina) have a weak (narrow) occipital carina laterally which is absent medially. Aulacus grossi is a small species (body 4.5 mm and ovipositor 4.2 mm in length) with the mesosoma and metasoma about equal in length. It can readily be distinguished from A. bamagensis, which has a length of 7.5 mm, excluding the ovipositor which is 3.0 mm in length, and the mesosoma is 1.77× the length of the metasoma. There are also numerous sculpturing and colour differences.

Similar to female except: length 5.3 (5.1���5.5) mm; last few metasomal segments with variable amounts of dark brown; genitalia black; digitus longer than penis valves and parameres (Fig. 23H). PUPA. Pupal case pale brown, testaceous, ovoid, 6.5 mm long�� 2.7 mm wide. LARVA. The larval skin is badly preserved. Head 2.5 mm broad; pronotum heavily sclerotised, dark brown; mandibles black, chisel-like, lacking teeth; clypeus with several stout setae. Distribution. The holotype was collected from an unknown location in NSW, with a number of paratypes collected from Petrie, Queensland (Fig. 60). Biology. This species is apparently a parasitoid of cerambycid larvae, but one label in ASCU in W.W. Froggatt's handwriting indicates that it may have come from either cerambycid or buprestid larvae. The larva and pupa were apparently bred from longicorn larvae (the label on the specimens is in W. W. Frogatt���s handwriting and were collected on the same date as the holotype adult). This is also the only Australian species where the larval and pupal stages are known. Comments. Aulacus fuscicornis is similar to A. rieki because both species have the mesoscutum rounded antero-dorsally in lateral view, fore wing without a brown spot apically, hind wing venation complete, metasoma ovate, and frons without a lateral medial carina above the toruli. However, they differ in a number of characters. Aulacus fuscicornis has a face that is rugose-reticulate and without punctures, head and mesosoma black, and metasoma orange except for variable amounts of black on T1, whereas A. rieki has a punctate-rugose face and body dark brown-black. The male is similar to the female but is smaller and has extra brown colouration on the last few metasomal segments., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 44-46, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367, {"references":["Hedicke, H.

This species is so named because of the distinctive colouration of the mesothorax, being pale orange in the anterior half and largely dark brown in the posterior half. Distribution. This species is known from several localities in Queensland and NSW over a distance of some 1,600 km (Fig. 56). Biology. The specimen from near Taree, NSW, emerged from a dead branch of Backhousia sciadophora (Myrtaceae). Comments. Aulacus bicolor is one of a number of species with the mesoscutum angular in lateral view, but is the only one of these species with a clavate metasoma. Aulacus bicolor also has the face punctate-reticulate and fore wing vein 2-Rs+M very long. The distinctive colouration of the mesothorax of this species distinguishes it from other Australian Aulacus species.

Aulacus belairensis Jennings, Austin & Stevens, 2004 Aulacus belairensis Jennings et al. 2004b: 14; Jennings 2010 [on-line checklist]. Comments. This species was described recently by Jennings et al. (2004b) from Belair, South Australia. In addition to the description provided in Jennings et al. (2004b), the ovipositor guide is distal, transverse, distal fringe with long setae, and no setae in the groove. Aulacus belairensis keys out with A. longiventris and A. houstoni. The three species can be readily separated by the lateral medial carina above the toruli, which is present in A. longiventris and A. houstoni but absent in A. belairensis. They can also be separated by the position of the ovipositor guide on the hind coxae (transverse and distal in A. belairensis, transverse, medial and broad in A. houstoni, and transverse and somewhat caudad in A. longiventris). There are also colouration differences (see key above)., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on page 22, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367, {"references":["Jennings, J.

Remarks. Aulacidae comprises two genera, Aulacus and Pristaulacus (see, for example, Smith 2001, Turrisi et al. 2009). For a recent synopsis of the systematics of the Aulacidae and taxonomic history, see Smith (2001), Jennings et al. (2004a, b), and Turrisi et al. (2009). Aulacus was recently redefined by Turrisi et al. (2009) within a cladistic framework. Aulacus can be distinguished from Pristaulacus by the following combination of characters: occipital carina absent (present in Pristaulacus); frons sculptured above antennal sockets (not sculptured in Pristaulacus); tarsal claws with one weak basal process, lacking tooth-like processes along inner margin (with three to four tooth-like processes along inner margin in Pristaulacus, i.e. pectinate); petiole (metasomal T1+T2) at most as long as wide in Pristaulacus (slender, at least 2.5�� as long as wide in Aulacus) (Turrisi 2007; Turrisi et al. 2009; Watanabe et al. 2013). Aulacidae currently comprises 264 extant species��� Aulacus with 83 species and Pristaulacus with 181 species (Turrisi 2017; Smith 2018). Turrisi (2017) recently analysed the distribution of the two genera and found that the family is represented in all zoogeographic regions except Antactica, with most species occurring in the Australian and Neotropical regions. Prior to this paper, 38% of the world Aulacus species were known from Australasia (Turrisi 2017), but the proportion of Australasian species is now 64%. Most Australian Aulacus are from the higher rainfall, forested areas of the east coast of mainland Australia and Tasmania, with just three species recorded from south-west Western Australia and four from South Australia (Jennings et al. 2004a, b). To date, no Aulacus have been collected from the Northern Territory., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 5-6, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367, {"references":["Latreille, P.

Etymology. The name for this species, aquilus, is from the Latin meaning 'dark coloured, swarthy, or blackish', and indicates the generally dark colour of this species. Distribution. Aulacus aquilus is known from several localities in southeastern Queensland and a single locality Oraparinna Creek, Flinders Ranges, in South Australia. Although the five specimens in MVMA are possibly from Victoria, we cannot be certain of this, and they have not been plotted on Fig. 55. Biology. Nothing is known of the biology of this species except for several specimens in MVMA "bred from sticks containing larvae of beetles". Comments. Aulacus aquilus is in a group together with A. bashfordi, A. froggatti and A. pallidicaudis, all of which have the mesosoma rounded antero-laterally in lateral view, metasoma ovate, and lack an ovipositor guide on the hind coxae. Aulacus aquilus and A. pallidicaudus both have a lateral medial carina above the toruli which is absent in the other two species. Aulacus aquilus and A. pallidicaudus can be readily separated by the sculpturing on the face (rugose in A. aquilus and rugulose-reticulate in A. pallidicaudus)., Published as part of Jennings, John T., Parslow, Ben A. & Austin, Andrew D., 2018, Systematics of the parasitoid wasp genus Aulacus Jurine (Hymenoptera: Evanioidea: Aulacidae) from Australia, pp. 1-113 in Zootaxa 4538 (1) on pages 14-15, DOI: 10.11646/zootaxa.4538.1.1, http://zenodo.org/record/3771367

Similar to female except scape dark brown; length 11.3 (10.0–12.5) mm. Etymology. This species is named for Richard (Dick) Bashford, forest entomologist. Distribution. This species has been collected from several localities in Tasmania (Fig. 56). Biology. Aulacus bashfordi has been reared from eucalyptus infested with Epithora dorsalis (Macleay) (Cerambycidae) or emerged from eucalyptus infested with Epithora dorsalis and Coptocercus rubripres (Cerambycidae). Comments. Aulacus bashfordi is in a group together with A. aquilus, A. froggatti and A. pallidicaudis, all of which have the mesosoma rounded antero-laterally in lateral view, metasoma ovate, and lack an ovipositor guide on the hind coxae. Aulacus bashfordi and A. froggatti both lack the lateral medial carina above the toruli that is present in the other two species. Aulacus bashfordi and A. froggatti can be separated by both sculpturing and colour differences. Aulacus bashfordi has a largely black body and rugose face whereas A. froggatti is a largely brown species and has a punctate-reticulate face (see key for additional colour differences).
