Augochloropsis peruviana Celis & Melo, 2022: 30 . Holotype female, Peru: San Martin, San Antonio de Cumbaza (MUSM, examined).

Comments: The male described here was collected in San Roque de Cumbaza, in Peru, a locality situated about 750 m above sea level and only 4 km from the type locality in San Antonio de Cumbaza. The specimen is partially damaged, lacking the left flagellum apically to the F1. After its photodocumentation, the posterior portion of the metasoma was dissected for the study of the genitalia and sterna.

In addition to the details described below, we also noted some form of sclerotization in part of the ventral bristles of the gonostylus (this can be seen as darkened portions of the bristles in Fig. 4B View Figure 4 ). Such characteristic is not exhibited by males of the other subgenera. Considering that only a section of the bristles is darkened, we are not sure whether they represent an artifact produced during genitalia preparation or an inherent feature of this group. We hope that this can be clarified with the discovery of other males of A. ( Glyptochlora ).
