Diagnosis
The pronotal foveae distinguish this species from all others on Sarawak. From C. foveolatum Johnson, 1982 from New Zealand, which has similar large foveae on the pronotum, it may be distinguished by the more sinuate margins of the pronotum, the lack of a deep medial fovea on the forehead between the eyes and the wider keel between the mesocoxae.
Etymology
Refers to the large foveae on the pronotum.

Description
SIZE. Habitus ( Fig. 6D View Fig ), length 0.89 mm.
COLOUR. Dark brown, antennae, legs and pubescence yellow.
HEAD. Distance across eyes 0.23 mm; antennomeres III–XI, length 0.39 mm; mentum parallel sided the lateral margins with slight insinuation, submentum with 4 long setae.
PRONOTUM. Length 0.22 mm, width 0.32 mm, with scattered pubescence and a row of foveae along the posterior margin, the four medial ones tending to form two large ones, side margins sinuate before the acute hind angles ( Fig. 7E View Fig ).
ELYTRA. Length 0.49 mm, width 0.55 mm, pubescent, shallowly foveolate, sides evenly rounded, broadest just before middle. Mesoventrum without pubescence, humeri with sharply projecting angles, lateral margins almost straight before turning to meet mesocoxae, each with ¾ serrations, keel parallel sided in posterior half widening slightly between the mesocoxae ( Fig. 8E View Fig ).
