Fig. 3 .

MATERIAL. Holotype, ♂: Malaysia W, Kelantan, 40 km N of Gua Musang, Gunung Benangkat Kampong Riek , 1100 m, 15.V. 2017, leg. Petr Cechovsky ( NME).

DESCRIPTION. Metallic green with entirely black antennae.

Body elongate ovate, 1.7 times Clypeus triangular with straight anterior margin, finely and densely punctate, microsculptured, frons and vertex practically impunctate, with deep longitudinal groove in middle. Antennae reach middle of elytra, proportions of segments are as 10-6-11-10-12-15-14- 14-14 (2 apical antennal segments absent). Prothorax 1.6 times as wide as long, broadest before base, with lateral margins not explanate, with moderately dense punctures and rather large smooth interspaces. Elytra 1.25 times as long as wide, with moderately strong and uniform punctures, including sides and apices, interspaces larger than punctures, flat or feebly convex. Propleurae shining, with a few punctures. All femora not toothed, posterior femora without brush. Aedeagus ( Fig. 3 ) distinctly widened to triangular apex. Length 4.2 mm.

DIAGNOSIS. This species belongs to species group 5 [ Medvedev, 2003] and might be placed near C. nigricollis Jacoby, 1884 and C. cechovskyi L. Medvedev, 2016 (all three species have entirely black antennae), but differs, except details of sculpture of head and prothorax, with form of aedeagus, very distinctly widened to apex, while both other species have parallel-sided aedeagus.

DERIVATIO NOMINIS. A name is connected with region of species distribution.
