The types of this species are from Perth, Kings Park (W.A.).
Head. 2 pairs of long ifr setae plus a short more anterior one on the right side. pvt negligible, occe and occi minute (0.03 mm or shorter). 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 View Figs 43–53 ) 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 View Figs 43–53 ). Ventro-medial process of synsternite with a pair of brushes of 20 black, blunt pegs caudally ( Figs 44–45 View Figs 43–53 ). 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 View Figs 43–53 ). Surstylus short and rounded, with an extremely long, thick, black thorn ( Figs 49–50 View Figs 43–53 ). Distiphallus ( Fig. 48 View Figs 43–53 ) short, with broad apex. Basiphallus comparatively large ( Fig. 48 View Figs 43–53 ). Postgonite long and slender, S-formed, with proclinate, sharp apex ( Fig. 48 View Figs 43–53 ). Phallapodeme very long (broken on the Fig. 93 of RICHARDS 1973).
Female genitalia ( Figs 51–53 View Figs 43–53 ). 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 View Figs 43–53 ); epiproct membranous, without setulae; hypoproct rather narrow. Spermathecae ( Fig. 53 View Figs 43–53 ) longish, pear-shaped, neck without any warts.
