The aurita species-group

(Figs. 1 a, 1d, 1g)

Diagnosis. The aurita species-group can be distinguished by the combination of the following characters: 1) occipital carina flange-like only basally (Fig. 1 a); 2) propodeal spiracle not joining the pleural carina by a short carina (Fig. 1 d); 3) first tergite with lateromedian carinae anteriorly not highly elevated (Fig. 1 g); and 4) triangular crests at anterior edge of mesoscutum highly elevated.

Remarks. The species of the group are widely distributed in the Neotropical region (Fig. 8) and some are abundant in rainforest habitats. The group was revised previously by Townes (1969).
