33. Conicera tibialis Schmitz ( Figs. 26A–D , 30G )

Conicera tibialis Schmitz, 1925: 119 (♂, Slovakia: Nagy-salló ).

Description. Male. Body length 1.1–1.7 mm. Frons dark brown. Supra-antennal setae present. Lower fronto-orbital setae absent. Lower interfrontal setae 1/2 length of upper interfrontal setae, and the distance between each other a little shorter than that between upper interfrontal setae. First flagellomere brown, 0.31 mm long, with an aspect ratio of 3:1; arista 0.31 mm long, equaled to that of first flagellomere. Palpus yellowish brown, with 6 short setae apically.

Thorax brown. Mid and hind legs brown, fore leg light brown. Fore tibia with 11 small near-dorsal setulae, the uppermost being longer than the rest. Mid femur ( Fig. 26D ) with a large drop-shaped pit and a short apical process. Wing ( Fig. 30G ) length 0.94 mm. Costal index 0.40, costal ratio 2.14:1, costal setulae length 0.055 –0.060 mm. Rs without basisetula. Halter brown.

Abdominal tergites dark brown. Terminalia ( Figs. 26A–C ) brown. Left surstylus ( Fig. 26B ) with a basidorsal process. Right surstylus ( Fig. 26C ) with arc-shaped apical edge, with inner teeth and a membranous basidorsal process.

Female. Unknown.

Distribution. China (Jilin, Liaoning, Zhejiang, Yunnan), Israel, Russia (Far East), Europe, North America.

Remarks. This species is recorded for the first time from China. It is similar to C. similis ( Haliday, 1833) , it is different from the latter by a large drop-shaped sensory pit which is about 1/2 width of mid femur. In the key of Disney (1990), the species runs to couplets 6, to C. flavipalpus Beyer, 1958 , it is differs by large drop-shaped pit, smaller aspect of first flagellomere (1.92: 1), presence of lower fronto-orbital setae and brown palpus; while C. flavipalpus Beyer without sensory pit on mid femur, larger aspect of first flagellomere (4.75: 1), absence of lower fronto-orbital setae and yellow palpus.
