Other material.

1 male, China: Yunnan (Province): Ruili (County): Mengxiu (Township), [25.0667°N, 98.4167°E], 2.v.1981, leg. Chikun Yang (CAU). 1 male, China: Yunnan (Province): Puer (City): Simao (District), [22.7860°N, 100.9798°E], 7.vi.1981, leg. Chikun Yang (CAU). 3 males, China: Yunnan (Province): Ruili (County): Mengxiu (Township): Tuanjiezhai (Village), [24.0917°N, 97.8460°E], 30.iii.2019, leg. Yaru Zhao (CAU).

Diagnosis.

Male genitalia: median apical incision V-shaped. Its depth is more than the half of the length of sternum 9. Terminal process long and acute in lateral view. Distal part of gonocoxites 10 bent upwards perpendicularly.

Measurements.

Forewing length 2.2-2.4 mm, width 0.8-1.1 mm. Hindwing length 1.5-1.8 mm, width 0.7-0.8 mm.

Description.

Male: Head (Fig. 9a, b ). Yellowish brown. Frons without projections. Compound eyes large. Antennae brown, 27-28-segmented, 1.2 mm in length. Scape and pedicel long and narrow. Basal flagellomeres two times wider than long, apical flagellomeres tapered. Flagellomeres scattered with scale-like setae at apex and two circles of hair-like sensilla; setae present on most segments except basal ones. Maxillary and labial palps yellowish brown.

Thorax. Brown. Meso- and metanotum with dorsal dark spots. Legs yellowish brown except the brown coxae.

Wing. Wing membrane light greyish brown, almost hyaline. Male terminalia (Fig. 10a-h ). Sternite 9 slightly higher than wide in lateral view; anterior margin arched in lateral view; apodeme along anterior margin wide, but interrupted or very thin ventrally; lateral process rounded and blunt; terminal process slender and acute in lateral view; median apical incision V-shaped with two short appendages in the middle. Gonocoxites 9 long and sinuated, distal section directed forwards perpendicularly and serrated. Gonocoxites 10 long and slender, bent upward distally, ventral process small. Gonapophyses 10 as a pair of long, slender rods.

Distribution.

China (Yunnan).

Etymology.

The species name is a Latin adjective referring to the minute serrations on the distal portion of gonocoxite 9.

Remarks.

The genitalia of the new species suggest a close relationship with Coniopteryx (Coniopteryx) wuyishana Yang & Liu, 1999. However, the two species differ in the shape of the sternite 9. The new species is characterized by having a V-shaped median apical incision while it is U-shaped in C. (C.) wuyishana . Moreover, in Coniopteryx (Coniopteryx) serrata the anterior margin of sternite 9 stretches forwards laterally and the apodeme along the anterior margin is very thin and interrupted ventrally. In contrast, C. (C.) wuyishana is characterized by a straight anterior margin of sternite 9, and a ventrally complete anterior apodeme of sternite 9.
