The species resembles C. illigeri, but the malar space is shorter (Fig. 138), the punctation of T2 is denser and the metascutellum is more raised in profile. Also the black spots of S2 are posteriorly more oblique in the female (Fig. 110). The head and mesosoma are mainly blue or greenish, but the mesoscutum and anterior margin of the pronotum are red or golden red in the female and golden green to greenish in the male. The mesoscutum is usually darkened medially in the male. The metasoma is mainly red in the female and golden greenish in the male with a greenish, bluish or black apical rim. T2 often has a black patch dorsally in the female.
