ZooBank: urn:lsid:zoobank.org:act:8D632CB5-27FB-4BAC-AA9C-4A6495D278F0

TYPE SPECIES: Trigona schultei Friese, 1901 .

DIAGNOSIS: This subgenus is equivalent to the dutrae -species group of Rasmussen & Gonzalez (2017) and consists of small bees, with head widths less than 1.6 mm

(versus larger than this in the nominate subgenus). Unlike typical species of Nannotrigona , the species of the new subgenus have the mesoscutum sparsely punctate and the integument shining between the punctures ( Fig. 123 ). This sculpturing contrasts with the denser, coarser, cribriform punctation of the mesoscutellum. In the nominate subgenus the punctation of the mesoscutum and mesoscutellum are both dense, coarse, and cribriform Fig. 122 ).

ETYMOLOGY: The new subgeneric name is a combination of the Greek líspos (λῐ́σπος, meaning, “polished”) and the generic name Trigona . The gender of the name is feminine.

INCLUDED SPECIES: Aside from the type species, the subgenus includes Nannotrigona (Lispotrigona) dutrae (Friese) .
