Diagnosis.

The genus can be easily identified by the wing patterning, which is dark centrally, with radiating hyaline stripes from the costal margin around to the posterior margin, and the posterior wing margin undulating between veins. Face yellow, with a pale brown subbasal and/or median band or spot and a pale brown groove near ventral margin; facial keel sometimes distinct or absent. Frons wider than long, with a pair of narrow brownish median stripes, parallel on anterior 1/2 and widened on posterior 1/2; two fronto-orbital setae, each with a blackish brown basal spot, two basal spots conjoined and forming a narrow stripe (not conjoined in N. tengchongica and N. decora ); ocellar triangle grayish black. Antennal 1st flagellomere tapering (round in N. parva and N. decora ); arista white or black, pubescent; ocellar seta strong, longer than anterior fronto-orbital seta. Mesonotum with 1+3 dorsocentral setae and 1+3 acrostichal setae (including prescutellar) in 1-2 rows, each dorsocentral and acrostichal seta situated on a brown basal spot. 1 strong anepisternal seta, and second anepisternal seta down-sloping and located near the middle of the anepisternum; 2 strong katepisternal setae. Scutellum slightly convex with dense microtrichia. Fore femur without ctenidium; hind femur with 1-3 strong anteroventral setae (absent in N. decora , 4 in N. huzhengkuni sp. nov.). Wing mostly brown with hyaline or white spots and radiating stripes from costal margin around to posterior margin; posterior wing margin undulating between veins; cells r2+3 and r4+5 wide apically; a short apical section of R2+3 bent forwards and apical section of M1 obviously arched. Abdominal tergites with grayish white, brown or fulvous spots and long setae on posterior margin. Male genitalia: epandrium with rows of dorsal setulae and setae in posterior view and surstylus consisting of one (in N. parva and N. decora ) or two processes (except for unknown male of N. aberrans and no male genitalic illustration of N. fulgens ). If the surstylus is comprised of two processes which are separated by a deep trench generally, then there are many setae and setulae on the anterior process.
