Colletes ravulus NOSKIEWICZ 1936

Colletes ravulus NOSKIEWICZ 1936 - NOSKIEWICZ 1936: 335-337.

The specimens assigned to C. edentulus in KUHLMANN (2009) all belong to C. ravulus as understood here.

Description of female: Colletes ravulus and C. tuberculatus differ only in the sculpture of the clypeus and in the punctation of the terga. In C. ravulus , the distance between the punctures of the clypeus is slightly broader (Fig. 3) than in C. tuberculatus (Fig. 1), but the sculpture is otherwise identical. In C. ravulus , the punctation on the disc of T1 is much denser and the punctures are slightly smaller (Fig. 6) than in C. tuberculatus (Fig. 4). In both species the punctation becomes much smaller and denser apically, but more so in C. ravulus (Fig. 6).
