Fig. 77
); apex of elytron narrowly yellow; venter with prosternum, epipleuron yellowish brown, meso- and metasternum brown, remainder of ventral surface and legs yellow; abdomen brownish yellow. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures smaller than on pronotum, separated by less than a diameter to 3 times a diameter, becoming gradually larger toward lateral margin; prosternal punctures coarse, sparse, mesosternal punctures large, separated by less than a diameter, nearly contiguous, metasternal punctures large, separated by two or three times a diameter medially, fine and sparse in lateral 1/3; basal abdominal ventrite with fine, indistinct punctures, ventrites 2–4 finely punctured, punctures separated by about a diameter, ventrite 5 with dense, fine punctation. Head with frons slightly narrowed between eyes, medially depressed, 1.5 times width of eye, apex faintly curved medially, lateral 1/8 slightly retracted, angle acute (
Fig. 78
); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process 2/3 distance to apex of prosternum, curved laterally. Epipleuron moderately descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 2/3 distance to rear margin of ventrite. Genitalia short, penis guide nearly as long as paramere, oval, anterior 1/3 abruptly narrowed to sharply rounded apex; paramere long, slender, weakly widened in middle, apex rounded (
Fig. 79, 80
); penis long, slender, apical 1/4 attenuate; penis capsule with inner arm long, slender, apically tapered to abruptly rounded apex, outer arm elongate, wide, apex broadly rounded (

Remarks.
This mostly black species is similar to
C
.
latoya
in external appearance and male genitalia. It differs from that species by a reduced yellow pronotal area, the apex of each elytron narrowly yellow, and the penis guide about as long as the paramere.
