Dicroaspis

An endemic Afrotropical genus with just two named species, Bolton (1981b) suggested that even these might be variations of the same form. The biology of this genus remains to a great extent unknown, although collection data suggests that these ants live in the leaf litter of rainforests. (Garcia, Wiesel and Fischer 2013)
