Holotype, ♂ ( MYNU), Shuikou-si Temple, Mt. Simianshan, Jiangjin District , Chongqing, 28°39′10.81″N, 106°21′21.39″E, 930 m, 11.V.2014, Jian-Yue Qiu & Hao Xu leg. GoogleMaps

Diagnosis. – A well distinguished species with metallic green head and pronotum, long antennae that greatly exceeding posterior angles of pronotum about the last three antennomeres, and yellow elytra. This new species is similar to C.platiai Schimmel &Tarnawskifrom Hubei, but it clearly differs from the latter by the sparser punctures on the pronotum disc, the yellow elytra, the shape of antennomeres, as well as the posterior angles of pronotum.

Description (based on male holotype)

Dimension. –Body length 8.3 mm.

Shape and coloration. – Shiny; head, pronotum, scape and pedicel, all margins and preapical portions of elytra, scutellar shield, as well as the entire ventral surface bright and metallic bluish green; the rest antennomeres black, with dark bluish reflection; legs dark brown dorsally. Body covered with whitish yellow short pubescence.

Head. – Frons slightly depressed apically; punctures umbilicate, almost contiguous. Antennae greatly exceeding posterior angles of pronotum about the last three antennomeres, serrated from antennomere 3 on; scape elongate oval, pedicel small, globous, antennomere 3elongate triangular, about 1.8 times longer than wide, antennomere 4-10 triangular, gradually slenderer, with the apical portion of serrated parts gradually tapered, the last antennomere elongate, apex rounded.

Pronotum. – Elongate, depressed along midline, about 1.1 times longer than width, widest at posterior angles; sides subparallel, slightly convex, posterior angles divergent, apices truncated; punctures umbilicate, intervals of punctures in middle about diameter of one puncture; punctures larger and denser laterally, sometimes almost contiguous.

Scutellar shield. – Covered with dense pubescence, tongue-shaped, with dense small punctures.

Elytra. – Elongate, about 2.7 times longer thanwidth, widestnear base; apical portion gradually narrowed, apices acute, not connected; surface of elytra wrinkled, striae formed by lines of round punctures, each puncture connected by grooved line; interstriae sparsely punctuated, usually only with 2 -3 punctures among the nearest four strial punctures.

Aedeagus (Fig. 19). – Typical of this genus.

Female and larva. – Unknown.

Etymology. – The specific epithet is dedicated to Dr. Jian-Yue Qiu (MYNU, China), one of the collectors of the holotype.

Distribution. – China (Chongqing).
