Remarks: The two species C. modiglianii and C. subcircularis share the features of a four-segmented antennal club and an oval to elliptical petiole with other members of the C. inflata -group, but do not have a swollen propodeum and a circular-shaped metapleural gland opening. The metapleural gland opening is comma-shaped in C. subcircularis (Fig. 7D).
