Introduction

This species is known from a number of localities in the Wet Tropics of North Queensland. Löcker (2014) recognised four different colour forms of L. praetextata as well as some variation in the structures of the male genitalia which were not correlated well with the colour variants. This variation was discussed in detail by Löcker (2014) on pp 29–30.
Löcker (2014) investigated the identity of the type series and determined that the specimens in NRS and MTKD which were labelled as the types of both Australoma praetextata and A. praetextata var. obscura did not match the descriptions given by Jacobi (1928) of those two taxa nor did the locality data associated with the specimens correspond with those published by Jacobi (1928). She subsequently found specimens in MTKD which were labelled as Leptochlamys apicalis and Leptochlamys apicalis var. obscura (R. Emmrich, pers. comm. 2004). These specimens matched the description and locality data for L. praetextata and P. praetextata var. obscura as published by Jacobi (1928) and were recognised by Löcker (2014) as the valid type series for those taxa. Löcker (2014) could find no record of publication of the names Leptochlamys apicalis nor Leptochlamys apicalis var. obscura and believed these names to be manuscript names only. The specimens in NRS and MTKD which were labelled as the types of A. praetextata and A. praetextata var. obscura were included in the type series of Leptolamia jacobii Löcker by Löcker (2014).

Diagnosis

Kopf, Brust und Beine gelbbraun, Stirn ohne die Kiele, Clipeus, Mesonotum, Mesopleurite und Hinterleib dunkel kastanienbraun. Deckflügel pechschwarz, bisweilen im Corium aufgehellt, Apicalteil hyalin mit feinem schwarzem Saume; Flügel dunkel rauchgrau. Stirn nicht »beträchtlich breiter als lang«, sondern wenigstens doppelt so lang wie breit, im übrigen der Diagnose und Abbildung Kirkaldy's ('07, p. 113) gleich, Deckflügel schmal, nach dem fast halbkreisförmig abgerundeten Apikalteile hin verbreitert; Costalrand dicht hinter der Basis aus-, dann und vor dem Stigma etwas eingebogen. Long. 5 mm. (Jacobi 1928).

Colour. Vertex light or mid brown with light brown to yellow carinae. Pronotum light brown or yellow; mesonotum dark brown (rarely light brown). Forewing varying in colour. Legs whitish or light brown, femora sometimes darker. Abdominal sternites mid brown. Morphology. Body length: ♂ 4.0–4.6 mm, ♀ 4.3–4.6 mm. Head: Vertex 1.5–2.0× wider than long; at level of basal emargination 1.1–1.4× wider than at subapical carina; apical carina v-shaped, subapical carina u- or v-shaped; median carina of vertex absent or incomplete (covering 1∕4–1∕2 of basal compartment of vertex); basal compartment 1.7–3.0× longer than apical compartment. Frons 1.1–1.5× longer than wide; frons just not or only just visible in dorsal view. Position of maximum width of frons more or less around centre of frontoclypeal suture to distinctly dorsad of frontoclypeal suture. Frontoclypeal suture semicircular, bent upwards. Rostrum reaching or surpassing hind coxae; apical segment of rostrum almost as long or distinctly shorter than subapical segment. Thorax: Pronotum moderately to distinctly wider than head (including eyes). Hind margin of pronotum obtusely or acutely angled or rectangular. Forewing 3.0–3.4× longer than wide; forewing with slightly developed basal emargination; costa with about 21–36 tubercles, tubercles concolorous with veins; Sc+R+M near basal cell fused, forming a long (more than half of length of basal cell) common stem Sc+R+M; fork of ScRA+RP moderately to distinctly basad, at same level or slightly distad of fork CuA1+CuA2; position of r-m distad of fork MA+MP; transverse veinlet M3+4 to Cu1a inserting at M3+4 basad of r-m; position of icu at CuAat same level as apex of clavus; position of icu at CuP more or less at same level or slightly distant of apex of clavus; RP apically trifid; MA apically bifid or trifid; additional subapical cell between branches of MA present in some specimens; nodus of y-vein slightly basad of centre of clavus; vein delimiting subapical cell C4 basad or distad of vein delimiting C5; 9 or 10 apical cells. Hind leg: 1st tarsomere with 6 (rarely 5 or 7) apical teeth; 2nd tarsomere with 6 (rarely 5) apical teeth. Male genitalia: Anal tube asymmetrical (rarely symmetrical) in caudal view; lateral lobe slightly bifurcate in lateral view. Ventromedian process of pygofer triangular or trapezoid, uniformly coloured. Aedeagus: Phallotheca left laterally with long, slightly curved spine (a) that can be bifurcate; dorsally with very long, curved spine (b) and short, outwardly directed spine (c); right laterally with sheet-like ridge, bearing upwardly directed spine (d); ventrally or ventrolaterally with upwardly directed spine (e). Flagellum without sclerotised spines (Löcker 2014).
