Hemipenthes neimengguensis View in CoL sp. nov.
( Figs. 7 View FIGURES 1 – 10 , 47–52 View FIGURES 47 – 52 )
Diagnosis. Hyaline part of cell r1 nearly semicircular; hyaline apical part of cell a small, subtriangular. Epandrium slightly longer than high in posterior view; epiphallus distinctly curved at middle, distiphallus narrow and long, subtriangular in dorsal view.
Description. Male. Body length 7–10 mm, wing length 7–11 mm.
Head black with gray pollen; ocellar tubercle reddish brown. Hairs on head black or yellow; frons with recumbent yellow hairs and erect black hairs; face with dense black and yellow hairs; occiput with sparse black and yellow hairs, and a row of erect blackish hairs on the edge; ocellar tubercle with seven black long hairs. Antenna yellowish brown; scape long cylindrical, three times longer than wide, with rows of long black hairs on both sides; pedicel nearly as long as wide, with sparse black hairs; first flagellomere onion-shaped, brownish, bare. Antennal ratio: 7:2:11. Proboscis dark brown with yellow and black hairs; palpus yellowish brown with black hairs.
Thorax black with brown pollen. Hairs on thorax yellowish and black, bristles on thorax black; hairs on postpronotal lobe mostly yellowish, mesonotum with row of long, yellow hairs along anterior margin and two long black lateral bristles near base of wing; laterotergite with a pile of yellowish hairs; postalar callus with three yellow bristles. Scutellum with yellow or black sparse long hairs. Legs black except tibiae yellow. Hairs on legs mostly black, bristles black. Femora with long black hairs; tibiae with short black hairs; tarsi with some short black hairs. Mid femur with three av apically; hind femur with three av apically. Mid tibia with seven ad, eight pd, seven av and 12 pv; hind tibia with 15 ad, 12 pd, eight av and 10 pv. Mid and hind tibiae with yellow scales. Wing ( Fig. 7 View FIGURES 1 – 10 ) half infuscate; hyaline part including entire cells r4 and m1, most part of cells r2+3, r5, m2, dm, and cu-a1, and little part of cells cup, a and r1; hyaline part of cell r1 nearly semicircular; hyaline apical part of cell a very small, subtriangular. Halteres black; knob pale.
Abdomen black with brown pollen. Hairs on abdomen yellowish and black; dorsum with long dense yellowish hairs laterally except tergites 1, 4, and 7; dorsum with black recumbent hairs, tergites 4 and 6 with a small mid-posterior area bare; tergites 9–10 with yellowish hairs. Sternites with yellow recumbent hairs and black erect hairs.
Male genitalia ( Figs. 47–52 View FIGURES 47 – 52 ). Epandrium subquadrate, nearly twice longer than high, and with distinct lateral extension at base in lateral view, epandrium slightly wider than high in posterior view; gonocoxa more or less narrowing backward, with a rather narrow middle incision apically and apicolateral lobes somewhat acute apically in ventral view; gonostylus without basal process, its apex acute and with a small V-shaped incision in lateral view; epiphallus distinctly curved at middle, with a clear curve line apically, distiphallus narrow and long, subtriangular in dorsal view, distiphallus distinctly narrowing apically in lateral view.
Female. Unknown.
Type material. Holotype male, CHINA: Inner Mongolia, Azuoqi, 7. VII. 2007, Gang Yao. Paratypes 4 males, the same as holotype; 2 males, CHINA: Inner Mongolia, Azuoqi, 8. VII. 2007, Gang Yao.
Distribution. China (Inner Mongolia).
Etymology. The species is named after the type locality Inner Mongolia.
Remarks. The new species is similar to H. mesasiatica (Zaitzev) , but it can be separated from the latter by the hyaline part of cell cu-a1 smaller and the epiphallus distinctly curved at middle with a clear curve line in dorsal view. In H. mesasiatica , the hyaline apical part of cell cu-a1 is rather large, more than half of the infuscate part, and the epiphallus is slightly curved at middle with a clear almost straight line in dorsal view ( Zaitzev, 1962).
