29. Conicera obtusidentis sp. nov. ( Figs. 23A–C , 30D )

Description. Male. Body length 1.1–1.4mm. Frons dark brown. Supra-antennal setae present. Lower interfrontal setae shorter, 1/2 length of upper interfrontal setae and the distance between each other equaled to that between upper interfrontal setae. Lower fronto-orbital setae short, slightly shorter than upper fronto-orbital setae. First flagellomere dark brown, 0.23 mm long, with an aspect ratio of 2.1:1; arista 0.32 mm long, 1.39 times length of first flagellomere. Palpus dark brown, with 7 short setae apically.

Thorax dark brown. Mid and hind legs dark brown, fore leg yellowish brown. Fore tibia with 11 small near-dorsal setulae, the uppermost being longer than the rest. Mid femur without sense-organ. Wing ( Fig. 30D ) length 1.43 mm. Costal index 0.36, costal ratio 1.5:1, costal setulae length 0.055 –0.070 mm. Rs with basisetula. Veins brown, except A 1 +CuA 2 whitish gray. Membrane hyaline. Halter dark brown.

Abdominal tergites brown. Terminalia ( Fig. 23A ) brown. Left surstylus ( Fig. 23B ) with 9 blunt and with a basidorsal process. Right surstylus ( Fig. 23C ) with 7 blunt inner teeth on dorsal edge and with a basidorsal process.

Female. Unknown.

Etymology. The specific epithet is derived from the Latin words obtusus (blunt) and dentis (tooth), indicating the characters of the inner teeth in dorsal edge of surstyli.

Specimens examined. Holotype, ♂, Qinghai, Datong, 7-July-2004, Hong Fang, Hongtao Han . Paratype, 1 ♂, Qinghai, Huzhu, 29-Jul-2004, Hong Fang .

Distribution. China (Qinghai).

Remarks. This species is similar to C. schnittmanni Schmitz, 1926 , but it is different from the latter by thick and blunt inner teeth of surstyli, the long basidorsal process and its more inner teeth. This species differs from C. floricola Schmitz,1938 , by thick and apical-blunt inner teeth and fewer number on each surstylus.
