Clypeus swollen, with thick pale pruinescence and long white hairs. Occiput with long white hairs except dorsal margin admixed with brown to black hairs. Posterior eye margin slightly sinuous. Antennae blackish brown; scape and pedicel with thin pale pruinescence and black hairs, ventral hairs of scape slightly longer, hairs on pedicel short. Scape 3.5× as long as wide, and 3.0× as long as pedicel, uniform from base to apex. Pedicel 1.1× as long as wide. Flagellum 4.6× as long as wide, 1.1× as long as scape+pedicel (1.5× as long as scape), conical and slightly laterally compressed, one-segmented with apical style ( Fig. 7c ). Palp thin and long, extending beyond oral cavity, black with blackish brown hairs, two-segmented, with palpal pit. Mouthparts slender, 3.0× as long as eye length (2.0× as long as head length), labella thin and filiform ( Fig. 7f ). Thorax. Integumental colour of scutum and scutellum mostly black with sparse grey pruinescence, pruinescence more dense around margins. Scutum and scutellum with admixed long white scales and white and blackish brown hairs. Three notopleural setae present. Postalar callus and posterior margin of scutellum with strong hairs. Notopleural setae and strong hairs on postalar callus and scutellum pale yellow. Scutum with two rows of distinct short, thick spines and some adjacent, separate spines. Pleura and coxae black with thick grey pruinescence, anepisternum and dorsal half of katepisternum with long white hairs, metepisternum with dense long white scales, and mediotergite with dense white hairs and setae, anepimeron, meron and laterotergite bare. Legs. Legs mostly dark brown, except hind femur basal half and fore and mid tibiae yellow. Femora and tibiae mostly covered with brownish-yellow scales, except femora and posterior face of fore and mid tibiae admixed with white scales. Other hairs and bristles on legs short and blackish brown to black. Fore tibia 2.2× longer than fore basitarsus, mid tibia 2.0× longer than mid basitarsus, hind tibia 1.9× longer than hind basitarsus. Figure 7.

Scale bars = 1 mm (a, b, d–h); = 0.1 mm (c). Figure 8. Thevenetimyia furvicostata ( Roberts, 1929 ) ♀: (a) dorsal; (b) lateral; (c) head, dorsal; (d) head, lateral; (e) wing; (f) head, frontal; (g) head, profile. Scale bars = 1 mm. Figure 9. Thevenetimyia furvicostata ( Roberts, 1929 ) Genitalia (a–e (♂); f, g (♀)): (a) genital capsule, dorsal; (b) genital capsule, ventral; (c) genital capsule, lateral; (d) epandrium, dorsal; (e) epandrium, lateral; (f) sternite 8, ventral; (g) genitalia and spermathecae. Scale bars = 0.1 mm. Wings. Wing membrane dark brown anterior 1/3, and posterior hyaline. Cell br with base 0.4 slightly infuscated, dark area along vein M , and covered crossvein r-m , a small hyaline area in posterior margin of cell r 2+3 between crossvein r-m and vein R 4+5 branching. Cell r 5 widely open; cell br much longer than cell bm , crossvein r-m arising a little over half way from the base of cell dm ; crossvein m-m long, and 2.0× as long as crossvein r-m ; cell cup open ( Fig. 7d ). Costa with two rows of short, thick spines. Haltere stem yellow, knob blackish brown. Abdomen. Integumental colour of tergites black with thin pale pruinescence, except lateral margin dark yellow. Tergites mostly covered with black scales and short black hairs. Tergite 1 covered with long white scales and hairs. Tergites 2 to 5 admixed with white scales laterally, and black scales on dorsal area. Sternites with dark brown integumental colour except posterior margins yellow, with thick grey pruinescence and white hairs. Genitalia. Epandrium wide and short, posterior margin slightly convex ( Fig. 9d ). Hypandrium present, constricted in the middle. Gonocoxal apex slightly narrower than the base in dorsal view, ejaculatory apodeme relatively small ( Figs 9a, b ); gonocoxal apodeme strong and incurved; lateral ejaculatory process strong, 2.0× longer than wide, apex not expanded; inner apex of gonocoxite rounded, elongate and broad; outer apex of gonocoxite rounded; dorsal bridge with long lateral hollow ( Fig. 9c ); gonostylus slender and pointed dorsally, 3.0× longer than wide. Female . Body length 8.0–12.0 mm, wing length 7.0– 9.5 mm , from Roberts (1929) . Very similar to male, except frons 2.5× as wide as ocellar tubercle, with short black hairs on dorsal half ( Fig. 8c ). Costa without small spines ( Fig. 8e ). Posterior margin of tergite 7 with slender dorsal median apodeme. Tergite 7 with ventral spines. Tergite 8 with a row of sparse hairs, 12 acanthophorite spines present, lateral spines long, spines in middle short, apex of spines expanded. Furca broad and connected at apex. Sperm pump strong and nearly as long as furca, not clothed in longitudinal muscle or lateral papillae; distal spermathecal duct short but strong; spermatheca elongate, cylindrical ( Fig. 9g ). Remarks . Thevenetimyia furvicostata ( Roberts, 1929 ) is redescribed and the images of external and internal characters are provided for the male. The allotype of Thevenetimyia furvicostata labelled: “ ♀ , QLD, Stanthorpe, Queensland , 27th January 1927 .” ( Roberts, 1929 ), is not in QM and is probably lost. Although Robert (1929) did not indicate where he deposit the paratype , PFMR found a specimen in NHMUK with the same label data. Despite this specimen has not a paratype label, it is probably the paratype originally designated by Roberts (1929) . Distribution . QLD.
