Supplementary description
The following description amplifies the type description of Darby (2019), in particular by adding more details of the meso- and metaventral characters, in order to conform with the entries in the present paper.
SIZE. Habitus ( Fig. 49A View Fig ), length 0.61 mm.
COLOUR. Pronotum and head almost black, elytra dark brown, shining, pubescence, antennae and legs yellow.
HEAD. With a row of indistinctly formed foveolae on a level with the top of the eyes; antennomeres III–XI, length 0.25 mm; mentum and submentum with ± circular foveolae (not always clearly defined) as Fig. 4A. View Fig
PRONOTUM. Length 0.19 mm, width 0.29 mm, foveolate throughout, two short carinae at the base very faint, apparently the result of the fusion of several foveolae; side margins angled medially, posterior margin with sinuous emargination in front of the scutellum ( Fig. 49B View Fig ).
ELYTRA. Length 0.43 mm, width 0.40 mm, smooth, evenly rounded, broadest at middle, pubescence as pronotum.
MESOVENTRITE. Collar with large medial patches without reticulation, medial extension narrow, sides slightly concave broadening posteriorly; mid-keel sides slightly concave, hind corners not reaching mesocoxal borders; keel tapering to parallel-sided between mesocoxae; mesoventral lateral margins serrate in posterior half; humeri sharply toothed ( Fig. 49C View Fig ).
METAVENTRITE. With scattered pubescence, length 0.18 mm, disc simple, width across spines 0.12 mm; mesocoxal posterior borders serrate.
Remarks
Only likely to be confused with C. marshallae in the other four Malaysian species in this group but lacking the pair of linear depressions at the pronotal base in that species
