Diagnosis. Santschi (1926). - "I restore this subgenus, which Emery had suppressed, by restricting it to the third species group of Myrmamblys of Emery, and for which C. moeschi Forel is the type. Thus subgenus differs from the other groups by its strongly constricted mesosoma, which brings it closer to the subgenus Karavaievia Emery; it is distinguished from this latter subgenus by its eyes, which are situated more posteriorly, very near the posterolateral angles of the head. Because of this, C. hypoclinoides Wheeler, having its eyes in the posterior third of the head, must be classified as a member of Karavaievia.
