Diagnosis. This species differs from other congeners by the following combination of characters: pronotum and elytra different in color; pronotal disc reddish yellow, with a blackish longitudinal maculation, sometimes with black spots on each side of the maculation; pro- and mesotarsal segments II and III of males moderately dilated; apical margin of tegmen usually subtruncate, rarely widely rounded in ventral view; lateral margins of median lobe subparallel; apical margin of median lobe widely rounded in ventral view; apex of long, slender gonocoxites deeply incised at apex.

Similar Species. This species is similar to C. costaricensis , C. maculatus , and C. epakros , but can be separated by possessing two antennal sensillae and the distinct shapes of male and female genitalia (see also of C. costaricensis , C. maculatus , and C. epakros ).

Redescription. Length 1.74–2.20 (2.09) mm, width 1.46–1.99 (1.71) mm, depth 0.88–1.14 mm (1.00) (n = 10). Male. Body ( Fig. 1F, H–I ) oval; dorsal disc of head (except apical paler area) and antennal club reddish yellow to dark reddish brown; antennal segments I–VIII reddish yellow; mouthparts, antennal segments I–VIII, abdominal tergites, and venter reddish yellow; pronotum reddish yellow with reddish yellow to dark reddish brown longitudinal maculation at midline, often with oval spot on each side of the longitudinal maculation; scutellum reddish yellow to dark reddish brown; elytra reddish brown to dark reddish brown, usually darker laterally than middle; venter reddish yellow to reddish brown, rarely prosternum, mesoventrite, and base of each femur darker. Head: Dorsal disc possessing sparse, minute punctures; interspaces reticulate. Labrum feebly notched at middle. Antenna ( Fig. 6G ) with club long and large, ACL/ASI-VIII = 0.84 (n = 1); antennal segment XI with 2 oval antennal sensillae; approximate ratio of each segment (n = 1) 4.27: 2.87: 2.44: 1.89: 1.87: 1.33: 1.00: 1.29: 4.44: 4.05: 5.80. Pronotum: 2.85–3.32 (3.13) times as wide as long (n = 10); disc possessing sparse minute punctures; interspaces reticulate. Scutellum: Disc possessing sparse minute punctures; interspaces reticulate. Elytra: 0.90–1.00 (0.95) times as long as wide (n = 10), 3.05–4.00 (3.56) times as long as pronotum (n = 10), widest at basal 1/3; each elytron with 9 regular rows of punctures about as large as eye facet; interstices with sparse, minute punctures. Venter: Prosternum feebly convex along midline. Metaventrite strongly convex. Abdominal sternite III without subcoxal lines. Legs: Slender; pro- and mesotarsal segments I to III moderately dilated; tarsal claws simple. Genitalia: Tegmen ( Fig. 6A, C, E ) constricted at mid-length, then moderately convergent apically in ventral view; TL/TW = 2.00 (n = 1); apical and lateral margins of tegmen strongly undulating in ventral view; apical margin of tegmen truncate ( Fig. 6A ), shallowly emarginate at middle ( Fig. 6C ) or widely rounded ( Fig. 6E ) in ventral view; median lobe ( Fig. 6B, D, F ) subparallel-sided at basal 1/2 or 2/3, then strongly converging anteriorly in ventral view; apical margin of median lobe widely rounded in ventral view; sclerites of internal sac as in Fig. 6B . Female. Pro- and mesotarsal segments I–III more weakly dilated than those of males. Ovipositor ( Fig. 6H ) with deeply incised apices of long, slender gonocoxites.

Variability. This species is widely distributed and many variations in body size and shape, pronotal maculation, and shape of male genitalia exist. The typical form ( Fig. 1F, H ) (specimens from Guatemala) has a large body without blackish spots on each side of longitudinal maculation of the pronotum, the elytra are subparallel-sided, and the apical margin of the tegmen ( Fig. 6A ) is subtruncate. Specimens from Peru and Bolivia ( Fig. 1I ) also have large bodies and blackish spots on each side of the longitudinal maculae of the pronota. The elytra are subparallel-sided, and the apical margin of the tegmen ( Fig. 6E ) is widely rounded. Specimens from Costa Rica and Panama also have blackish spots on each side of longitudinal pronotal macula (rarely absent). Some specimens from Costa Rica are smaller and more rounded, and coloration of these specimens is paler than the typical form.

Distribution. Guatemala, Honduras, Costa Rica, Panama, Ecuador, Peru, and Bolivia (Map 2).
