Description
Male. Body length 6.5–7.8 mm. Body color black and body hairs slightly flat. Head: eye covered with sporadic short hairs; frons about 2.0 times as wide as anterior ocellus; frontal vitta black, wider than one fronto-orbital plate; without interfrontal seta, frontal setae 10–12, the upper pairs reclinate, without orbital seta; and with 4 pairs of ocellar setae, all longer than frontal setae, fronto-orbital plate and parafacial black; antenna black, parafacial as wide as 1st flagellomere; 1st flagellomere about 2.0 times as long as wide, the distance between its lower margin and epistoma equal to the width of antenna; arista ciliated, the longest seta about 2/5 width of 1st flagellomere; facial carina narrow and distinct, frontal angle protruding in profile, vibrissal angle situated in front of frontal angle in profile; gena black, with 2–3 rows of upcurved subvibrissal setulae, genal height about 2/9 of eye height, beard and postgena setae all black, dorsal area of occiput with hairs; proboscis thin and long, prementum with grey pruinosity, about 5.0 times as long as broad; palpus black, about 3/4 length of prementum, labella enlarged apically.
Thorax. Ground color black, with sparse grey pruinosity and olive green metallic luster; presutural area of scutum with four grey median vittae, and with 2 rows of presutural acr, postsutural acr 1, dc 2+3, ia 0+2, without pra; notopleuron with hairs; lateral and ventral margins of scutellum, basisternum of prosternum, anepimeron, meron and katepimeron all bare; katepisternal setae 1+2.
Wing. Light brown, wing base and veins brown; basicosta black, costal spine not developed, R4+5 and M veins parallel, more or less separated distally; calypters light brown, their margins brown; halter black.
Legs. Entirely black; fore tibia with 3 pv in the middle; mid femur with straight av in distal half, and stronger in distal half, also with a row of pv, stronger towards apical part; mid tibia without ad, 4–5 pd, 3–4 pv; hind femur with a complete row of long av, setae in pv row longer towards apical part, hind tibia with a complete row of about 9–10 av, ad row with 10–12 setae, and with 3–5 thick pd, 2–3 pv, with a finger-like apical ventral projection that is lacking large setae, only with some hairs apically; claws of fore and mid legs short, only about 1/3 length of pulvilli, claws of hind legs slightly longer than pulvilli, each tarsus longer than tibia.
Abdomen. Black, tapered, with brownish-grey pruinosity, also with olive green metallic luster, tergite 9 with fringe-like setae, all tergites with indistinct lateral patch, abdominal sternite 1 with dense and long hairs; outboard processes of cerci very large and deeply emarginated in posterior view; processes on inner margin of surstylus pointed in the middle in lateral view.

Type material
Holotype, male, P.R. CHINA: Xinjiang, East Kunlun, Kaerdong Wave, 4100 m, 28.vi.1984 (Xue-zhong Zhang).
The specimen is deposited in Institute of Entomology, Shenyang Normal University, Shenyang, China.
Remarks
This species resembles Drymeia naticerca, but it differs from it in frons about 2.0 times as wide as anterior ocellus; frontal setae 10–12, the upper pairs inclined towards the top; hind tibia with a finger-like apical ventral projection but without setae on the projection.
Etymology
The species name is from the Latin words nud- meaning bare and apica meaning apical part, referring to male hind tibia with a finger-like apical ventral projection and without setae on the projection.
