15. Conicera convallis sp. nov. ( Figs. 14A–E )

Description. Male. Body ( Fig. 14A ) length. 1.06 mm. Frons dark brown. Supra-antennal setae present. Lower fronto-orbital setae absent. Lower interfrontal setae shorter than upper interfrontal setae and the distance between each other equaled to that between upper interfrontal setae. First flagellomere brown, 0.15 mm long, with an aspect ratio of 1.91:1; arista 0.27 mm long, 1.84 times as long as that of first flagellomere. Palpus dark brown, with 6 short setae apically.

Thorax brown. Mid and hind legs brown, fore leg yellow. Fore tibia with 12 small near-dorsal setulae, the uppermost being longer than the rest. Mid femur without sense-organ. Wing length 1.18 mm. Costal index 0.40, costal ratio 1.60:1, costal setulae length 0.05 mm. Rs with basisetula. Veins brown, except A 1 +CuA 2 whitish gray. Membrane hyaline. Halter brown.

Abdominal tergites brown. Terminalia ( Figs. 14D–E ) brown. Left and right surstyli triangular, reversely symmetric. Left surstylus ( Figs. 14B, D ) with a shorter posterior edge, dorso-apical corner with 14 inner teeth. Right surstylus ( Figs. 14C, E ) with a longer dorsal edge, ventro-apical corner with 14 inner teeth.

Female. Unknown.

Etymology. The specific epithet is derived from the Latin word convallis (valley), indicating the habitat of the species. Chawaron, where the specimen was collected, means "hot canyon" in Tibetan.

Specimen examined. Holotype, ♂, Xizang, Linzhi, Chawalong , 20-Aug-2020, Guangchun Liu.

Distribution. China (Xizang).

Remarks. In the keys of Disney (1990) and Michailovskaya (2000), the species will not run out to any species properly. This species is a little similar to C. chayuensis sp. nov., but it is different from the latter by blunt dorso-apical corner of left surstylus and triangular right surstylus.
