Genus Nannotrigona Cockerell

The genus Nannotrigona Cockerell comprises 14 species found from northern Mexico to southern Peru, Bolivia, Paraguay, and southeastern Brazil. The genus is one of the more distinctive of New World Meliponini owing to the combination of a shining, mediolongitudinal depression anteriorly on the mesoscutellum ( Figs. 122, 123 ), a strong preoccipital carina, and a dense, coarse, cribriform punctation on the mesoscutellum ( Figs. 122, 123 ), and often on the head and mesoscutum as well. Within the genus there are two distinctive groups (Rasmussen & Gonzalez, 2017), here treated as subgenera.
