(Figs. 8–14)
Description. Male. Body length 6.2 mm. Head: Eye sparsely covered with moderate hairs, the upper and inner facets not enlarged; frons as wide as anterior ocellus; frontal vitta black, obliterated at middle part; frontal setae 13 pairs, extending to both sides of anterior ocellus, upper 8 to 9 pairs short, about equal to eye hairs, without orbital setae; frontoorbital plate, parafacial and gena with gray pruinosity; parafacial about equal or narrower than the width of flagellomere 1; antenna black, flagellomere 1 about 2.5 times as long as broad; arista long haired, the longest aristal hairs about 1.5 times as long as width of flagellomere 1; lower facial margin with the anterior margin of frons in the same vertical plane; genal height about 1 / 5 of eye height; genal and postgenal hairs entirely black; proboscis short, prementum with gray pruinosity and fine hairs, prementum about 2.5 times as long as broad; palpus black, long and thin, longer than prementum; labella large.
Thorax. Black in ground color with sparse greenish gray pruinosity; scutum with four black indistinct vittae; scutellum black; acr 0+ 1, dc 2 + 4, ial 0+ 2, pra strong, about 2.0 times as long as posterior notopleural seta; notopleuron with hairs; lateral margin and lower surface of scutellum, basisternum of prosternum, meron and katepimeron bare; both anterior and posterior spiracles dark brown; katepisternal setae 1 + 2.
Wing. Slightly hyaline, veins dark brown, basicosta dark brown, subcostal sclerite brown; costal spine short; dorsal and ventral surfaces of radial node bare, distal part of R 4 + 5 and M straight, area around crossveins r-m and dm-cu not clouded; calypters brownish, halter yellow.
Legs. Entirely black; fore tibia without mid p; mid femur without row of distinct av, with a row of pv in basal half; mid tibia with 3 p, without ad and pv; hind femur with a row of sparse av, a row of short pv on distal half, 4 thick; hind tibia with 4 av and 2 ad, 1 pd on distal 1 / 5, without apical pv; tarsi longer than tibia, first tarsomere of hind leg equal to the length of remaining tarsi; claws and pulvilli small.
Abdomen. Ground color black, rounded in dorsal view, with thin greenish gray pruinosity, slightly shiny, syntergite 1 + 2 and tergite 3 each with a slender but distinct black median vitta, stripe on tergite 4 indistinct, tergite 5 without median vitta; all tergites without versicolor patches; sternite 1 bare; lateral lobe of sternite 5 long, about 3 / 8 length of sternite 5; cerci rounded in dorsal view, the inner projection longer than the outer one, basal part of surstylus narrow, becoming enlarged toward distal part.
Female. Body length 6.8 mm; frons about 1 / 3 of head width, frontal vitta about 4.0 times as wide as fronto-orbital plate; frontal triangle reaching the middle part of frons; with a pair of orbital setae, curved outward; frontal setae 6 pairs, pv on basal half of hind femur shorter than in male; distal half of sternite 8 and tergites 6 to 8 all divided into two parts. The other characters are the same as in male.
Type material. Holotype, male, CHINA: Hanmi, 9530 E, 2920 N, 2150–3200 m, Mêdog, Tibet, 9. viii. 2003 (Ming-fu Wang) (IESNU).
Paratype, CHINA: 1 female, same data as holotype.
Remarks. This new species resembles P. hirtiorbitalis and P. xixianga Xue, 1996 (Ma et al. 2002), but it is distinguished from it in having frontal setae 13 pairs, extending to both sides of anterior ocellus, upper 8 to 9 pairs short, about equal to eye hairs, without orbital setae; legs entirely black; hind tibia with 4 av and 2 ad. Furthermore, it also resembles P. hirtiorbitalis sp. nov., and yet it is distinguished from it by frons about equal to the width of anterior ocellus; palpus black; mid tibia with 3 p; abdomen without versicolor patches.
Etymology. This specific name is formed from the Latin words, nigr -, black, fusc-, fuscous and coxa-, coax, referring to legs entirely black.
Distribution. China.
