Halter dark brown. Abdomen brown with gray-brown pollen except brownish lateral margin; hairs and bristles black. Genitalia ( Figs. 14–15 ): epandrium with one long pale hair on short lateral tubercle; surstylus with dorsal lobe thick, rounded apically, middle lobe long and thick with apical tubercle, ventral lobe slender with long apical hairs; cercus without distinct basal tubercle, but with pale short hairs; hypandrium short and wide, symmetrical in ventral vision, bifurcated, with narrow base and wide apical portion; aedeagus slender with spine-like processes at middle. FEMALE. Unknown. Type material. Holotype male, Guangdong: Nanling, 23. VIII. 2005 , Junhua Zhang. Distribution. Guangdong. Etymology. The specific epithet derives from the collector Junhua Zhang (Beijing). Comments. The species is somewhat similar to N. horvati Wang et Yang in having the bifurcated hypandrium bearing narrow base and wide apical portion, but it may be separated by the hind tibia having two ad and 5–6 pd, and the hind tarsomere 1 with two v at base. In N. horvati , the hind tibia has one ad and 3–4 pd, and the hind tarsomere 1 has one v at base ( Wang and Yang, 2004 ).
