Diagnosis.

Male genitalia: median apical incision shallow, U-shaped, less than half of sternite 9 length; terminal process blunt in lateral view; distal part of gonocoxites 10 short and stout, with tiny hairs.

Measurements.

Forewing length 2.0-2.8 mm, width 1.0-1.3 mm. Hindwing length 1.5-1.7 mm, width 0.5-0.7 mm.

Description.

Male: Head (Fig. 7a, b). Brown. Frons without projections. Compound eyes large. Antennae brown, 28-segmented, 1.2-1.5 mm in length. Scape and pedicel broad and blunt. Basal flagellomeres wider than long, distal flagellomeres gradually tapering toward apex, apical flagellomere almost as long as wide. Apices of flagellomeres covered with scattered scale-like hairs and two whorls of setae. Maxillary and labial palps brown. Thorax. Yellowish brown. Meso- and metanotum dorsal dark spots. Legs yellowish brown, except the brown coxae.

Wing. Wing membrane light greyish brown, almost hyaline. Male terminalia (Fig. 8a-g). Sternite 9 higher than wide in lateral view; anterior margin straight laterally; ventral apodeme along anterior margin not interrupted; lateral process rounded and blunt; terminal process short and acute in lateral view, rounded and blunt in caudal view; median apical incision shallow and U-shaped, and its depth less than half the length of the sternite 9. Gonocoxites 10 long and slender, bent downwards near apex, distal portion serrated and covered with many tiny setae. Gonapophyses 10 as a pair of long, slender rods.

Distribution.

China (Tibet, Yunnan).

Etymology.

The species name Coniopteryx tenuisetosa “thin-haired” is a composed adjective of Latin derivation, referring to the thin setae on the distal portion of gonocoxites 10.

Remarks.

The new species is similar to Coniopteryx (Coniopteryx) aspoecki Kis, 1967, but the two species differ in configuration of the male genitalia. In particular, Coniopteryx (Coniopteryx) tenuisetosa is characterized by a short, not prominent terminal process of sternite 9 in lateral view, while it is prominent and arched in C. aspoecki . Moreover, in the new species, the distal portion of gonocoxites 10 is relatively robust and serrated, while in C. aspoecki it is thin, apically tapered and smooth.
