Description.

Body elongate elliptic, moderately convex. Mandibles, head, pronotum, scutellum, elytra and ventral surfaces dark chocolate brown, with pronotum darker, almost black; labrum, femora and tibiae dark testaceous, and antennae and tarsi testaceous; palpi ochre. Length: 4.5 mm; width: 2.6 mm.

Frons unpunctured with supraocular sulci prolonged medially beyond middle of dorsal edge of supraantennal calli; clypeus with few small punctures basally and anterior border moderately emarginate. Eyes large, separate on frons by 2.2 × their transverse diameter. Relative proportions of antennomeres: 2.2-1.0 - 1.5 - 1.8 - 2.1 - 1.9 - 2.4 - 2.3 - 2.3 - 2.2 - 2.6. Posterior border of pronotum with seam of few tiny punctures laterally on furrow. Prosternal process as wide as transverse diameter of procoxae. Elytra about 1.3 × as long as ensemble width at base, widest behind humeri; surface finely alutaceous, slightly shinier than pronotum, with relatively large punctures, as big as intervals, rather confused elsewhere on disc. Basitarsomeres shorter than second and third tarsomeres combined in pro- and mesotarsi, and as long as these in metatarsi. First abdominal ventrite slightly longer at middle than ventrites 2–4 combined with median apodeme nearly half as long as ventrite, subtrapezoidal, much narrower than mesosternal process; all ventrites with fine microreticulation, sparse fine punctures and long fine, posteriorly adpressed pale yellow setae. Spermatheca (Fig. 1 g View Figure 1 ) 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 relatively thick, inserted laterally near, but not at base of nodulus, oriented opposite to cornu and recurved oblique at acute angle relative to nodulus and longer than nodulus before enlarged elongate coil. — Males. Unknown.

Diagnosis.

This species belongs to the C. thyiana group, recognizable, among others, by the broad prosternal process, as wide or wider than transverse diameter of procoxae in females, and specifically to the subgroup lacking tiny setae apically on epipleura that, apart from C. ovata sp. nov., it includes the much larger C. holosericea sp. nov. and C. thyiana (Jolivet, Verma & Mille) .

Derivatio nominis.

Name derived from the Latin adjective (f.), ōvāta, derived from ōvum (= egg), meaning egg-shaped, ovate.

Distribution.

The only specimen available for study of this species was collected at moderate elevation (650 m a. s. l.) in Aoupinié (Fig. 8 d View Figure 8 ).
