( Figs 28, 29 )

Holotype, male. China, Yunnan, Xiaguan-Dacang , 19 km, 08.VI.2002, 1900 m, river side, N 25°28'53" E 100°15'42" A. Konstantinov & M. Volkovitsh leg ( IZAS) . Paratypes 22 specimens. China, Yunnan, Tiger Leaping Gorge , 2000 m, N 27°04'53" E 100°04'31", 25. V .2002; Dali-Lijiang , 40 km, 2500 m, 24. V .2002, N 26°04'54" E 100°09'39"; Xiaguan-Kunming Rd. 150 km, 1600 m, N 24°59'06" E 101°43'43", 10. VI .2002, A. Konstantinov & M. Volkovitsh leg. (18 USNM, 4 ZMAS).

Body length 4.0 mm, width 2.0 mm. Body bluish-green with metallic lustre. Labrum and antennae, except antennomere one, black. Antennomere one with greenish luster. Legs blackish-green. Abdomen, except ventrite one, orange-yellow.

Antennal calli convex, delimited by deep furrows. Frontal ridge strongly convex, widening triangularly ventrally. Frons and vertex smooth and shiny. Labrum large, convex, with groups of long setae on sides. Antennae shorter than body. Antennomeres two as long as three, antennomere four slightly shorter than two and three together.

Pronotum 1.34 times wider than long with sides evenly rounded and maximum width in middle. Disc with two shallow, round impressions covered with sparse and small punctures. Lateral explanation wide on anterior and posterior corners, well visible from above.

Elytra three times as long as pronotum and 1.5 times as wide as long. Maximum width posterior of middle. Elytral punctures small. Distance between punctures as long as diameter of puncture in basal part, apically punctures much smaller. Aedeagus as in Figs 28, 29 .

Comments: Calomicrus yunnanus is close to C. parvicollis (Weise) from which it can be separated by the shape of the sides of the pronotum being more convex and the shape of the aedeagus. The apical part of the aedeagus is strongly converging posteriorly with a small notch at the tip. The apical part of the aedeagus of C. parvicollis is widened abruptly, flattened and lacks notches at the tip.

Etymology: The species name refers to the type locality.
