Hyphaenia volkovitshi Lopatin , new species

( Figs 11–13 View FIGURES 11–13 )

Holotype male, China, Yunnan, env. of Lijang, Tiger Leaping Gorge , 2000m, N 27°04'53" E 100°04'31", 25.05.2002, A. Konstantinov & M. Volkovitsh leg. ( IZAS). GoogleMaps

Body length 5.3 mm, width 1.8 mm. Most of body, ventral portion of head, gena, pronotum, pro- and mesosterna, and legs yellow. Antenna black, antennomere two entirely and antennomere one ventrally reddish yellow, apical parts of tibiae and tarsi dark.

Frons with deep, transverse depression. Frontal ridge short and wide. Antennal calli transverse, convex. Antenna ( Fig. 11 View FIGURES 11–13 ) long, covered with erected hair starting with antennomere three. Hairs on outer side of antennomeres long, nearly as long as width of antennomeres. Antennomere two short, not longer than its width. Antennomeres four to nine oblique at apices. Antennomere four with two impressions on outer surface. Antennomere five constricted in middle, widening apically. Proportion of antennomeres as follows: 11:2:10:15:13:12:11:10:10:10:11.

Pronotum 1.4 times wider than long. Sides strongly converging from anterior one third posteriorly and weakly anteriorly. Surface with large depressions on sides divided by wide interspace. Lateral margin narrowly explanate. Anterior setiferous pore situated slightly below anterior corner, posterior setiferous pore situated on top of posterolateral corner.

Elytra 4 times longer than pronotum and 2.2 times longer than wide at humeral calli. Elytral surface weakly shiny, covered with dense small punctures, weakening at posterior one third. First protarsomere elongate, as wide as cross-section of profemoral apex. Aedeagus as in Figs 12, 13 View FIGURES 11–13 .

Comments: Hyphaenia volkovitshi is similar to H. bicolor Medvedev from Thailand, but can be easily differentiated by the shape of the antenna and the aedeagus.

Etymology: This species is named after the collector, M. Volkovitsh.
