Description.

Body elongate elliptic, moderately convex. Dorsum, venter, coxae and mandibles very deep brown, with faint bronze reflections dorsally; labrum, antennae and legs testaceous, with base of tibiae and apical antennomeres except apex of eleventh antennomere infuscate; palpi ochre. Length: 4.1 mm; width: 2.2 mm.

Frons with sparse small punctures and supraocular sulci prolonged medially to half of dorsal edge of small supraantennal calli; clypeus with sparse small punctures except near anterior angles, sides parallel and anterior border moderately emarginate. Eyes large, separate on frons by 2.6 × their transverse diameter. Relative proportions of antennomeres: 2.0-1.0 - 1.4 - 1. 7-2.0 - 1.8 - 2.2 - 2.1 - 2.1 - 2.0 - 2.7. Narrow explanate lateral margin of pronotum with tiny punctures on inner border; surface of pronotum coarsely microreticulate as on frons with relatively dense punctures, as large as intervals, interspersed with some micropunctures; sides of disc and lateral declivities wrinkled by shallow longitudinal or slightly oblique furrows connecting punctures. Prosternal process nearly as wide as transverse diameter of procoxae. Elytra about 1.2 × as long as ensemble width at base, widest behind humeri; surface microreticulate, cells slightly larger than on pronotum, entirely glabrous except for very few short setae near sutural angles, with relatively large punctures, bigger than intervals on disc, tending to relatively regular geminate rows on first three rows; last two intervals convex in apical 2 / 3, other intervals weakly convex in apical third, and inner intervals in lateral declivities with transverse rugae. Epipleura notably enlarged preapically before apical constriction, with tiny setae in apical border. Basitarsomeres narrower than third tarsomere and shorter than second and third tarsomeres combined in all tarsi. First abdominal ventrite longer at middle than four other ventrites combined, with median apodeme less than half as long as ventrite, arched, narrower than mesosternal process; all ventrites with fine microreticulation, relatively dense fine punctures and short fine, posteriorly adpressed pale yellow setae. Spermatheca (Fig. 1 s View Figure 1 ) hook-shaped, 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 inserted laterally near base of nodulus, oriented opposite to cornu for short distance, recurved parallel and as long as nodulus, forming one complete, elongate coil. — Males. Unknown.

Diagnosis.

This species has punctures as big as intervals and tendency to gemination on disc of elytra, and epipleura strongly enlarged preapically with setose apex, traits only shared with C. striata (Jolivet, Verma & Mille) and C. subgeminata sp. nov. But they can be distinguished by the corrugation of pronotum and elytra of C. corrugata sp. nov., as well as the presence of extended punctation on frontoclypeus, nearly absent in C. subgeminata , and the apex of elytra with very few setae, compared with C. striata , showing abundant pubescence.

Derivatio nominis.

The name of the species refers to the wrinkled appearance of sides of pronotum and rugose sides of elytra, using the participle (f.), corrūgāta, of the verb corrūgō, to wrinkle.

Distribution.

At present, the species is known from a single female collected at moderate elevation (400 m a. s. l.) in Pic d’Amoa, being one of the species with a northernmost distribution in the island of Grande Terre (Fig. 8 b View Figure 8 ).
