Hemipenthes hamifera Loew

( Figs. 4 , 29–34 )

Anthrax hamifera Loew, 1854: 2 . Type locality: “Sibirien” [= Russia (ES or WS)].

Diagnosis. Cell bm with a gray spot apically, infuscate part extending from cell m1 into cell m2. Gonocoxa more or less narrowing backward, with a large V-shaped middle incision apically. Epiphallus nearly quadrate, but slightly narrowing near base; distiphallus subtriangular in dorsal view.

Description. Male. Body length 8–11 mm, wing length 9–12 mm.

Head black with gray pollen; ocellar tubercle reddish brown. Hairs on head black or yellow; frons with recumbent yellow hairs and erect long black hairs; face with dense black and yellow hairs; occiput with sparse yellow hairs and a row of erect yellow hairs on the edge; ocellar tubercle with four long black hairs. Antenna black except first flagellomere brown; scape long cylindrical, two times longer than wide, with long black bristle-like hairs; pedicel nearly as long as wide, with sparse black hairs; first flagellomere onion-shaped, brownish, bare. Antennal ratio: 2:1:3. Proboscis dark brown with black hairs; palpus dark brown with black hairs.

Thorax black with brown pollen. Hairs on thorax mostly white, bristles black or yellow; postpronotal lobe with white and yellow long hairs, mesonotum with row of yellow long hairs at anterior margin and three long black lateral bristles near base of wing, postalar callus with three yellow bristles. Scutellum with yellow or black sparse long hairs. Legs brown with yellow scales and gray pollen. Hairs on legs mostly black, bristles black. Femora with long black hairs; fore tibia with some short yellow hairs; fore tarsus with some short yellow hairs, mid and hind tarsi with short black hairs. Mid femur with three av apically; hind femur with three av apically. Mid tibia with 6–8 ad, 7–8 pd, 6–8 av and 6–8 pv; hind tibia with 9–12 ad, 7–10 pd, 7–10 av and 6–9 pv. Femora and tibiae with yellow scales except fore tibia. Wing ( Fig. 4 ) half infuscate; hyaline part including entire cell r4, most part of cells m1, m2 and cu-a1, part of cells r2+3, r5, dm, cup, and a, and little part of cell r1; cell bm with a gray spot apically, infuscate part of cell r2+3 extended to cell r4, infuscate part extending from cell m1 into cell m2. Halteres brown, except knob pale.

Abdomen black with brown pollen. Hairs on abdomen white, black and yellow; dorsum with long dense black hairs laterally except tergites 1 and 4 with white hairs laterally; dorsum with black and yellow recumbent hairs except tergite 1 bare and tergites 4 and 6 with white and yellow recumbent hairs, tergites 5–7 with a small mid-posterior area bare; tergites 9–10 with white and black hairs. Sternites with yellow recumbent hairs and erect black hairs.

Male genitalia ( Figs. 29–34 ). Epandrium subquadrate, distinctly longer than high, and with distinct lateral extension at base in lateral view, epandrium twice higher than wide in posterior view; gonocoxa narrowing posteriorly, with a large V-shaped middle incision apically and apicolateral lobes somewhat acute apically in ventral view; gonostylus with a basal process, its acute tip strongly curved in lateral view; epiphallus nearly quadrate, but slightly narrowing near base, with a clear W-shaped line apically, distiphallus subtriangular in dorsal view, distiphallus narrowing apically.

Female. Body length 10–12 mm, wing length 10–12 mm. Similar to male, but infuscate part of cell r2+3 extended to cell r4, and infuscate part of cell m2 little bigger, scutellum with yellow hairs, abdominal tergites 2 and 3 with yellow hairs.
