MATERIAL. Holotype, ♂ “ Philippines, Luzon : Lagunas, Los Banos, vegetation debris near small river, 28.XI.1995, J. Kodada & B. Rigova lgt.” ( MHNG) . Paratypes: 1♀ “ Philippines, Luzon : Lagunas, Los Banos, vegetation debris near small river, 28.XI.1995, J. Kodada & B. Rigova lgt.” ( MHNG) ; 1♂ (teneral) “ Philippines, Luzon , Los Banos, small river, 28.XI.1995, J. Kodada & B. Rigova lgt.” (cMG) .
DESCRIPTION (holotype). Length 2.0 mm. Colouration dark brown, legs and antennae light brown. Integument slightly shining, body with short, light-coloured hairs.
Head transverse, with a wide base, ratio of its length (from posterior margin of head to anterior margin of clypeus) to maximum width about 19:28. Neck constriction prominent. Eyes large, convex. Temples well-developed, round, eye dimeter in dorsal view markedly longer than temple length, but less than 1.5 times as long as temple length. Head about as wide across eyes as across temples ( Fig. 3 View Figs 1–4 ). Head surface with delicate, fine and dense punctation. Diameter of punctures about 2.5 times as small as eye facet. Distances between punctures about equal to their diameter, interspaces smooth, slightly shining. Antennae rather short ( Fig. 3 View Figs 1–4 ), antennal segments 1–3 elongate; segments 4–5 and 7 slightly elongate; segments 6 and 8–10 about as long as wide; segment 11 elongate, conical (structure of segments 9–11 from male paratype). Last 3 segments more massive than others and form loose club.
Pronotum widest about 2/3 its length from base, then narrowed. Lateral margin smoothly rounded ( Fig. 3 View Figs 1–4 ). Ratio of pronotum length to its maximum width about 23:31. Surface of pronotum with delicate, fine and dense punctation; punctation similar to that on head. Pronotal disc with 2 pairs of prominent, symmetrical depression and 1 unpaired oval depression along midline near apex. Base of pronotal disc with narrow, crescent-shaped depressions barely separated by medial ridge. Central part of disc with rather deep, oval depressions fused across midline to single butterfly-shaped depression ( Fig. 3 View Figs 1–4 ).
Ratio of length of elytra to their combined width about 35:39. Scutellum with shallow, round depressions ( Fig. 3 View Figs 1–4 ). Elytra with rather delicate, fine and dense punctation. Diameter of punctures about equal to that of eye facet. Distances between punctures significantly smaller than their diameter, interspaces smooth, slightly shining.
Abdomen delicately shagreened.
Aedeagus of characteristic structure ( Figs 10–11 View Figs 5–14 ).
Female. Sexual dimorphism absent, female morphologically similar to male. Spermatheca failed to isolate and its structure is unknown.
COMPARATIVE REMARKS. The new species is similar and closely related to C. notumus sp.n. and C. vilisus sp.n. (see descriptions above). It differs from both species in having a significantly larger body size and a larger punctation on the body surface and can be clearly distinguished by the structure of the aedeagus ( Figs 5–6, 8–11 View Figs 5–14 ).
DISTRIBUTION. Philippines.
ETYMOLOGY. From Latin “plenus ” (full, dense) referring to a relatively large body size.
