Diagnosis.
This species is similar to C. protuberans , C. tenuous , and C. seleuyensis in general appearance (e.g., the elytra yellow without any spots and broad), but can be distinguished from them by the anterior part and apex of penis hatchet-shaped with irregularly serrated coupled teeth. In C. protuberans , the penis is long and slender, with a large penis capsule and apex of penis is curved, with many small teeth. In C. tenuous , penis is very long and slender and apex of penis has many large teeth. In C. seleuyensis , penis is longer than in other species and apex of penis is partly membranous, with many small teeth.

Eyes oval, widest interocular distance 0.54 times head width (eye W/HW = 1:1.87). Frons broad with irregular transparent spots, punctures uniform and dense (Fig. 1c, d View Figure 1 ).
Pronotum 0.55 times elytral width (PW/TW = 1: 1.83), moderately transverse, with irregular transparent spots, punctures uniform and dense (Fig. 1c View Figure 1 ). Elytra with transparent humeral angles, punctures uniform and dense (Fig. 1a-c View Figure 1 ). Male genitalia (Fig. 1t-w View Figure 1 ): penis guide in lateral view wide at base and uniformly narrowing to pointed apex; parameres distinctly longer than penis guide, uniformly slender with densely distributed long setae apically (Fig. 1t, u View Figure 1 ); penis tubular, extremely long, curved; flabellate part of penis capsule very broad, anterior part and apex of penis hatchet-shaped with irregularly serrated coupled teeth (Fig. 1v, w View Figure 1 ).
