Description.

Body elliptic, moderately convex. Antennal calli, temples, median depression on vertex, mandibles, pronotum and hypomera very dark brown, almost black with slight bronze shine; elytra, scutellum and most of ventral surface brown, with faint dark blue metallic shine on elytra and scutellum; most of frons and clypeus brown with slight bronze metallic shine; labrum, antennae and legs testaceous, with base of tibiae and femora infuscate; palpi and apex of eleventh antennomere ochre. Length: 5.2 mm; width: 2.7 mm (range of male specimens: 4.5–5.4 mm long, 2.4–2.9 mm wide).

Frons with few small punctures anteriorly and supraocular sulci prolonged medially to middle of dorsal edge of supraantennal calli; clypeus with few small punctures basally and anterior border moderately emarginate medially. Eyes large, widely separate on frons by 1.8 × their transverse diameter. Relative proportions of antennomeres: 2.2-1.0 - 1.9 - 2.1 - 2.6 - 2.3-2.7 - 2.4 - 2.4 - 2.3 - 2.9. Prosternal process about 0.75 × as wide as transverse diameter of procoxae. Elytra about 1.25 × as long as ensemble width at base, widest behind humeri; surface finely alutaceous, shinier than pronotum, with relatively large punctures, smaller than intervals, rather confused anteriorly on disc. Basitarsomeres enlarged, as wide as third tarsomere, shorter than second and third tarsomeres combined in pro- and mesotarsi, and as long as these in metatarsi. Median apodeme of first abdominal ventrite about half as long as ventrite, arched, narrower than mesosternal process; all ventrites with fine microreticulation, sparse fine punctures and long fine, posteriorly adpressed pale yellow setae. Penis (Fig. 7 m ) slender, regularly curved ventrally, with sides nearly parallel in ventral view; apex elongate, arched, projecting short blunt tip at middle; gonopore relatively small, elongate elliptical, with distal end separated from apex of penis by distance longer than maximum width of gonopore; dorsal flap subrectangular, longer than wide, covering slightly more than half of gonopore. — Females. Spermatheca (Fig. 1 d ) with cornu shorter than nodulus, bent more or less at right angle relative to nodulus; nodulus bulbous basally, with short protruding insertion of spermathecal gland submedially, opposite to cornu; spermathecal duct thin, inserted laterally near base of nodulus, oriented opposite to cornu and recurved parallel and about as long or slightly longer than nodulus before gradual enlargement with one complete, elongate coil.

Diagnosis.

This species can be distinguished from other species with body proportion> 1.8, subparallel and completely glabrous brown elytra, testaceous legs and antennae and prosternum narrower than procoxae, by punctures on disc of elytra generally smaller than intervals and by the relatively even surface of anterior lateral declivity of elytra in females, compared to the females of C. laevigata sp. nov., which have slight rugosities. The penises of these two species show marked differences too.

Derivatio nominis.

This species is dedicated with affection to Prof. Marek Wanat (Uniwersytet Wrocławski, Wrocław, Poland) for confiding us his excellent collection of New Caledonian Eumolpinae for study. This resource has been the key to most recent advances in the systematics of this group.

Distribution.

All the specimens of this species were collected near the summit of Mont Do, a high peak (1003 m a. s. l.) in an isolated ultramafic island northwest of the Massif du Sud (Fig. 8 e ).
