Genus Geotrigona Moure

The genus Geotrigona Moure includes 22 species of small, robust, short-legged, typically black or dark brown species of stingless bees occurring from southern Mexico to northern Argentina ( Michener, 2007; Gonzalez & Engel, 2012). As the name implies, where known species nest in the cavities in the ground. Gonzalez & Engel (2012) provided a key to the species. Here the genus is organized into two subgenera.
