A key to the subgenera of the stingless bee genus Melipona (Hymenoptera: Apidae)

The infrageneric classification of the stingless bee genus Melipona Illiger (Apinae: Meliponini) has historically consisted of four subgenera. Here a slightly expanded subgeneric system is presented in the context of a key to subgenera, with two new subgenera established: Meliponotes subgen. n. and Mouremelia subgen. n.
