Wing subhyaline, tinged with light brown; pterostigma brown; cell m1 sessile, cell m1 and cell d narrow; apices of R5 not curving up (Fig. 36 View Figures 34–36 ). Halter pale yellowish brown.

Abdomen (Fig. 34 View Figures 34–36 ). Mainly yellow. Abdominal tergites each with three brown spots, lateral spots rather narrow and fused with each other; tergite 1 without spot, median spot on tergites 2 and 3 roughly rectangular, on tergites 4-8 subtriangular. Abdomen with yellow and brown hairs.

Hypopygium (Figs 37-42 View Figures 37–42 ) mainly dark yellow. Tergite 9 medially produced, with notch, lateral side with a pointed projection with spines (Fig. 42 View Figures 37–42 ). Sternite 8 depressed at posterior margin, medially with a sickle-shaped, fleshy appendage bearing long apical hairs (Figs 37 View Figures 37–42 , 39 View Figures 37–42 ). Sternite 9 with a subtriangular appendage (Figs 37 View Figures 37–42 , 39 View Figures 37–42 ). Outer gonostylus fleshy, small, anteriorly slightly expanded, apically pointed (Fig. 38 View Figures 37–42 ). Inner gonostylus with concavity at base; beak sharp, posterior margin with a small protuberance with five bristles (Figs 40 View Figures 37–42 , 41 View Figures 37–42 ).

Distribution.

China (Xizang).

Remarks.

This new species is similar to N. korpa Alexander, 1967 from India (Sikkim), but the latter differs in the following characters: posterior vertex with three brown spots at narrowest point; projections of tergite 9 smaller, but lateral projections without spines; outer gonostylus unusually long, basally expanded.
