27. Conicera grandicaudata sp. nov. ( Figs. 22A–C, G–H , 30B)

Description. Male. Body length 1.4–1.5 mm. Frons dark brown. Supra-antennal setae present. Lower interfrontal setae short, 1/2 length of upper interfrontal setae and the distance between each other shorter than that between upper interfrontal setae. Lower fronto-orbital setae short, 1/2 length of upper fronto-orbital setae. First flagellomere dark brown, 0.20–0.21 mm long, with an aspect ratio of 1.83–1.90:1; arista 0.38–0.39 mm long, 1.80–1.86 times length of first flagellomere. Palpus dark brown, with 7 short setae apically.

Thorax dark brown. Mid and hind legs brown, fore leg yellowish brown. Fore tibia with 8 small near-dorsal setulae, the uppermost being longer than the rest. Mid femur without sense-organ. Wing ( Fig. 30B ) length 1.42 mm. Costal index 0.40–0.42, costal ratio 1.78–2.36:1, costal setulae length 0.062 –0.078 mm. Rs with basisetula. Veins brown, except A 1 +CuA 2 whitish gray. Membrane hyaline. Halter dark brown.

Abdominal tergites brown. Terminalia ( Fig. 22A ) brown, large, 0.40–0.45 mm long. Left surstylus ( Figs. 22B, G ) with 14–16 pointed teeth on dorsal edge and with basidorsal process. Right surstylus ( Figs. 22C, H ) with 14–18 pointed inner teeth on dorsal edge, and with a basidorsal process.

Female. Unknown.

Etymology. The specific epithet is derived from the Latin words grandis (large) and caudatus (tail), indicating the characters of terminalia.

Specimens examined. Holotype, ♂, Ningxia, Mt. Liupan, 15-Jul-2005, Hong Fang . Paratypes, 10 ♂, same data as for holotype ; 1 ♂, Ningxia, Mt. Liupan , 5-Jul-2008, Lixin Su .

Distribution. China (Ningxia).

Remarks. This species is similar to C. schnittmanni Schmitz, 1926 , it is distinguished from the latter by larger size of terminalia and more inner teeth of surstyli. It also differs from C. floricola Schmitz, 1938 by shorter basidorsal process and more inner teeth of right surstylus.
