Description

SIZE. Habitus (Fig. 9A), length 0.66 mm.

PRONOTUM. Length 0.17 mm, width 0.25 mm, glabrous with six basal foveae the two inner pairs united to give the appearance of two large foveae, the outer foveae detached, small; lateral margins rounded almost parallel in basal third, narrowly bordered to rectangular hind angles, not continued along the posterior border which has a sinuous emargination before the scutellum (Fig. 9B).

ELYTRA. Length 0.45 mm, width 0.35 mm, glabrous.

Remarks

The glabrous and strongly foveate pronotum is shared with C. glabratum sp. nov. and C. semicalvum sp. nov. both also from Madagascar, but C. franzi sp. nov. may be distinguished from them by the presence of the two small ancilliary foveae between the large foveae and the pronotal lateral margins.
