C04982023B29FF8FFE7EFB9FFC8A9E10.taxon	description	The extended description of the genus is given below. Head. Head wide with small but distinct ocelli, gena wide. Frons without silvery stripes, i. e. unicolourous. Head setae uneven: oc seta long, vti long and thick, vte minute, 2 latero-clinate ors and 4 pairs of ifr present. Vibrissa strong and long, pm setae weak, no strong genal seta. Thorax. In dorsal view, very wide dorsal to mid coxae. Posterior part of mesothorax and whole metathorax are with a deep, subcylindrical vertical emargination (Papp 1979: fig. 9), which embraces mid and hind femora when at rest. Thoracic chaetotaxy: 1 ppnt, 2 np, and 1 pair each of prsut, sa, small pa and dc setae. 1 pair of thin kepst. Scutellum very short (about 3 times broader than long), with 2 pairs of strong sc setae. Acrostichals short and numerous. All species are wingless, and only A. australis and A. flavipes have halteres, those are small. Legs. Short and more or less thickened. Mid tibia with a strong va, no mid ventral seta. Antero-dorsal and postero-dorsal setae are paired at basal 1 / 3 and at about apical 4 / 5. Hind tibia without dorsal preapical seta. Abdomen. Barrel-shaped, in males only slightly shorter than head and thorax combined. Preabdominal tergites and sternites extremely strongly developed (sclerotised) and meet laterally. Both males and females with 5 visible preabdominal segments (tergites and sternites). Tergites covered by dense thin, and moderately long microchaetae. Articulation of abdomen to thorax is comparatively broad. Male genitalia (Figs 1 – 15). See in the above key. Female genitalia. Tergites 6 – 9 wholly membranous. Epiproct weakly sclerotised with a pair of dorsal setulae (Figs 16, 18). Cerci longer with longer setae (Figs 16 – 18); its apical seta about 0.05 mm. Hypoproct U-shaped, very thin. Sclerotised duct of paired spermathecae comparatively short, duct of single spermatheca also comparatively long. Spermathecae better sclerotised and with a large bulb on initial section of duct (Figs 19 – 20).	en	Papp, László (2021): New Species Of Apterobiroina L.

Although, it seems less probable that among these apterous flies, the Tasmanian female is conspecific with that one from New South Wales. I cannot make a distinction of this specimen to the paratype. Consequently, I designated it also as a paratype.	en	Papp, László (2021): New Species Of Apterobiroina L. Papp And Bentrovata Richards (Diptera, Sphaeroceridae) From Australia.

Proboscis comparatively very large. Scape’s seta minute. Arista emerges from dorsal middle surface of flagellomere. Thorax. Yellow, some parts of pleura ochre. Scutellum twice broader than long. Legs. Predominantly yellow, only mid part of femora light brown. Mid femur with an anterior subapical thorn. Mid tibia with ad-pd setae at 3 / 10 and 4 / 5 and a short, more anterior seta at 29 / 40. Ventroapical seta of mid tibia 0.14 mm long. Abdomen. At broadest 0.87 mm. Sternite 2 (Fig. 43) consists of a pair of small medial and a pair of larger lateral sclerites. Length of tergites 2 – 5 (mm): 0.30, 0.39, 0.34, 0.21. Male genitalia. Contours of sternite 5 is the same as Richards’s fig. 91. Dorsal part of synsternite short (Fig. 46). Ventro-medial process of synsternite with a pair of brushes of 20 black, blunt pegs caudally (Figs 44 – 45). Epandrium deformed on Fig. 92 of RICHARDS (1973) (depressed), consequently much broader than in its original form / state. Hypandrium fused to epandrium, with a medium-long medial apodeme. Pseudocerci small but distinct (Fig. 47). Surstylus short and rounded, with an extremely long, thick, black thorn (Figs 49 – 50). Distiphallus (Fig. 48) short, with broad apex. Basiphallus comparatively large (Fig. 48). Postgonite long and slender, S-formed, with proclinate, sharp apex (Fig. 48). Phallapodeme very long (broken on the Fig. 93 of RICHARDS 1973). Female genitalia (Figs 51 – 53). Length of tergite 4: 0.25 mm, that of tergite 5: 0.16 mm. Tergite 7 so short that it looks like a piece of transverse, thread-like dirt. Cercus minute, with very short setulae (Figs 51 – 52); epiproct membranous, without setulae; hypoproct rather narrow. Spermathecae (Fig. 53) longish, pear-shaped, neck without any warts.	en	Papp, László (2021): New Species Of Apterobiroina L. Papp And Bentrovata Richards (Diptera, Sphaeroceridae) From Australia.
