Identification
Cyrtolobus are distinguished from other Nearctic by pronotal features including the presence of a distinct carina and specific patterns of lobing or curvature. Within the tribe Smiliini, Cyrtolobus differs from closely related genera such as Telamona and Archasia in details of pronotal shape and the extent of projection. Species-level identification requires examination of pronotal contours, carinal development, and male genitalia. The genus is not known to exhibit the extreme -mimicry seen in some other smiliine genera like Cyphonia.
