The description by Lundbeck (1922) is supplemented by Figs 1–8 View FIGURES 1–2 View FIGURES 3–6 View FIGURES 7–8 and comments below. Male frons as Fig. 7 View FIGURES 7–8 , but in addition there are four differentiated robust hairs either side of the SAs. The postpedicel (third antennal segment) has numerous SPS vesicles whose diameters range between those of the hair sockets to those of the SAs sockets. Labella of both sexes with fewer than twenty scattered spinules below each. Notopleuron with three bristles and male with a fully exposed orifice of the notopleural gland duct (N in Fig. 2 View FIGURES 1–2 ). Right posterolateral lobe of male epandrium strongly extended rearwards and lobes at rear of hypandrium greatly reduced ( Fig. 8 View FIGURES 7–8 ). Female abdomen with orifice of common duct of paired dorsal glands between tergites 5 and 6 ( Fig. 6 View FIGURES 3–6 ). Paired lobes at rear of segment 8 of venter heavily pigmented ( Fig. 5 View FIGURES 3–6 ). Furca (internalised sternite 9) an irregular hoop with an associated vaginal sclerite ( Figs 4–5 View FIGURES 3–6 ). Hairs below basal half of hind femur not differentiated from adjacent hairs of anterior face. Spinules of apical combs of hind tibiae all simple. Wings ( Fig. 1 View FIGURES 1–2 ) with outer half of costa a little thickened; no hair at base of vein 3; costal cilia relatively short; Sc strong and fusing with R1; at least the first three thin veins (veins 4–6) brown; several axillary bristles; membrane with well developed, dense, microsetae.
