Holotype.
Philippines: 1 male, Puerto Princesa, Palawan Is, sea level, secondary growth forest, IV 47.
Paratype.
1 female, Philippines, Puerto Princesa, Palawan Baker.
Diagnosis.
This species is similar to C. uncinacanthus , C. protuberans , C. tenuous , and C. seleuyensis by the strongly convex, yellow elytra having no spots. But unlike these species, its body is small, the anterior and apex of the penis is tubular with irregular dense tiny teeth. In C. uncinacanthus , the apex of the penis is hatchet-shaped and bears large teeth; in C. protuberans , the apex of the penis is curved and membranous, with many small teeth; in C. tenuous , the apex of the penis is straight and membranous, with many asymmetrical large teeth.
Description.
TL: 2.33-2.40 mm, TW: 2.26-2.28 mm, TH: 1.11-1.21 mm, TL/TW: 1.03-1.05; PL/PW: 0.37-0.47; EL/EW: 0.94-0.97 HW/PW: 0.53-0.55; PW/TW: 0.58-0.59; HW/TW: 0.31-0.32; Eye W/HW: 0.33-0.41.

Pronotum 0.59 times elytral width (PW/TW = 1:1.7), moderately transverse, punctures uniform (Fig. 2a, c View Figure 2 ). Elytra with humeral angles, punctures uniform and dense (Fig. 2a-c View Figure 2 ). Male genitalia (Fig. 2t-w View Figure 2 ): penis guide wide at base in lateral view and uniformly narrowing to pointed apex; parameres obviously longer than penis guide, uniformly slender with densely distributed long setae apically (Fig. 2t, u View Figure 2 ); penis tubular, extremely long, curved; flabellate part of penis capsule broad, anterior and apex of penis with irregular tiny dense teeth, and apex of penis nest-shaped (Fig. 2v, w View Figure 2 ).
