Description

Male. Body length 3.4–4.6 mm. Anepisternal disc present. First flagellomere orbicular. Bristles brown.Arista pubescent. Vibrissa relatively long and curved. Ocellar bristle minute. Two dorsocentral bristles. Gena shallow and not sharply angled. Face and buccal cavity pilose and meeting at an angle. Head mostly yellow; antenna (excluding arista) light yellow with dark inner-basal spot; back of head with one pair of brown stripes radiating from foramen; upper half of gena and anterodorsal half of occiput white and silvery tomentose; gena with central rusty spot; posterior half of occiput (excluding venter) brown; frons with pilose anteromedial and anterolateral patches. Scutum yellowish-orange with one pair of brown stripes uniting at anterior margin and with three pairs of brownish lateral spots. Scutellum yellowish-orange with lateral margin brown. Laterotergites yellowish-orange. Pleuron yellow with anterodorsal corner of anepisternum dark brown, posterior and dorsal margins of anepisternum rusty, and anepimeron brown. Legs yellow with fore tibia and tarsi dark brown, and fore femur with thin oblique innerdistal spot. Fore tarsi compressed laterally. Abdomen dark brown with tergites 1 and 2 orange-brown. M 1+2 ratio 5.0. Wing lightly clouded. Halter white.

Female. As described for male except as follows: notal stripes wider and background of postsutural scutum orange; tergites 1 and 2 yellow laterally; terminalia yellow.

Male terminalia ( Figs 38–40 View Figures 38–46 ). Epandrium relatively small. Cerci thin and deeply emarginate. Surstylus small and rounded with apex slightly truncated and outer face setulose; inner-distal margin with numerous tubercle-like bristles. Hypandrium+pregonite with two thin divergent lobes (anterior lobe with two stout apical bristles and posterior lobe setulose distally). One rib of distiphallus thin, pointed and bent backwards, and one rib wide and elaborate apically with posteriorly-directed subapical lobe.

Female terminalia. Not dissected.

Etymology. The specific name notes the resemblance to the similarly-coloured H. hypoleuca   , while indicating that the fore tarsi are brown (- brunnea), not white (- leuca)—the best character to use when separating the two species.
