The neotropical stingless bee genus Nannotrigona Cockerell (Hymenoptera: Apidae: Meliponini): An illustrated key, notes on the types, and designation of lectotypes
Аннотация:We provide comparative comments on the morphology and provenance of the primary types of the species in the stingless bee genus Nannotrigona Cockerell. We offer an illustrated key to workers of all presently known species and designate lectotypes for the following species to stabilize their names: N. dutrae (Friese), N. mellaria (Smith), N. punctata (Smith), and N. schultezi (Friese). The type of Melipona minuta Lepeletier de Saint Fargeau could not be located and it remains an incertae sedis, but a possible member of Nannotrigona. A distinctive new species from western Ecuador, Nannotrigona camargoi n. sp. (type locality Ecuador, Pichincha) is also described and figured.
