Supplementary description

The following description amplifies the type description of Darby (2013), in particular by adding more details of the meso- and metaventral characters in order to conform with the requirements of the present paper.

SIZE. Habitus ( Fig. 16 A ), length 0.79 mm.

COLOUR. Yellow brown, very shining, antennae and legs dusky yellow.

HEAD. With a shallow median fovea between the eyes, antennomeres III–XI length 0.39 mm, III–IX 0.20 mm, X–XI 0.19 mm.

PRONOTUM. Length 0.18 mm, width 0.26 mm, with two foveae on each side tending to form a single fovea of distorted shape; lateral margins sharply angled, parallel before hind angles which are slightly acute, narrowly bordered, the border not continuing along the posterior margin, the emargination in front of the scutellum sinuous ( Fig. 16 B ).

ELYTRA. 0.52–54 mm long, 0.37–0.40 mm wide, sparsely and shallowly foveolate particularly along sides of the scutellum and suture, tapering strongly to apex.

MESOVENTRITE. Mid-keel very short, anteriorly with two rounded corners either side of the median process of the collar, posteriorly with two pointed corners not reaching the mesocoxae, strongly raised to point before meeting keel, keel parallel-sided terminating in a rounded end between the mesocoxae; humeri with small teeth and hind margin sloping posteriad ( Fig. 16 C ).

METAVENTRITE. Glabrous, disc simple, posterior margins of mesocoxae with slight serrations near interruption in borders.

WINGS. Male macropterous, female micropterous/apterous.

GENITALIA. Male aedeagus as Fig. 6 Fa–b. Female spermatheca globular.

Remarks

Distinguished from C. bifoveolatum sp. nov. the only other Madagascan species with a pubescent pronotum by its larger size, much sparser and shorter pronotal pubescence and pronotum with angular lateral margins.
