Description:
Male.
Frons brown, midline length about equal to maximum breadth, microtrichia absent, with only 7 hairs toward each side, 2 below antial bristles and none in middle. Bristle sockets surrounded by pale spots. Supraantennal bristles well below antials, which are a little lower on frons than anterolaterals. Likewise mediolaterals are a little lower than preocellars. No bristles on cheeks and a pair on each jowl. Antenna dusky yellow to increasingly brown towards base of arista, which is brown, and with pedicel and postpedicel as in Fig. 3 View Figs 1–3 . Palps with brown basal segments and yellow second segments, and each of latter bears 5 apical bristles and numerous fine hairs along its lower edge. Labrum brown basally, but pale yellow distally and only about 0.8× as broad as a postpedicel. Labella pale. Thorax brown, being darkest on top. Notopleuron with 3 bristles, front one being clearly longer and more robust than two behind. Scutellum with single pair of strong bristles. Abdominal tergites brown, with fine hairs which are a little longer on T6 ( Fig. 1 View Figs 1–3 ). Venter brownish grey on sides, but more greyish yellow below, and with only a few hairs on segment 5, but several longer hairs on segment 6. Hypopygium very pale to pale yellow in parts and as in Fig. 1 View Figs 1–3 . Legs yellow apart from brown patch on mid coxa, tip of hind femur and most of hind tibia. Front tibia with neardorsal spine in basal third followed by row of weakly differentiated hairs. All tarsal segments with posterodorsal hair palisade and segment 5 a little longer than 4. Mid tibia with 2 longitudinal hair palisades, anterodorsal one being sharply deflected onto anterior face just beyond anterodorsal bristle of basal pair of bristles. Base of hind femur as in Fig. 2 View Figs 1–3 . Hind tibia with anterior bristle in basal quarter and a series of transverse dorsal combs between two hair palisades. Wing 4.2–4.3 mm long. Costal index 0.45. Costal ratios 5.5:1.0:1.0. Costal cilia 0.16–0.17 mm long. Vein Sc weak and fading well before reaching vein 1. Strong hair at base of vein 3. With 5 axillary bristles, all but most basal being clearly longer than costal cilia. All veins brown. Membrane brownish grey (clearly evident to naked eye when viewed against a white background).
