RESUMO

ABSTRACT A new stingless bee genus, Plectoplebeia gen. nov., is proposed to accommodate a peculiar Neotropical species currently placed in Plebeia Schwarz, 1938. The brief, but convoluted taxonomic history of its type species, Trigona nigrifacies Friese, 1900, is documented, with Trigona (Plebeia ) intermedia Wille, 1960 being placed as its junior synonym. Plectoplebeia gen. nov. resembles an enlarged species of Plebeia , differing by its larger body size, wider distance between the clypeus and the eye, presence of a shallow depression on the frons above the antennal sockets, coarser punctures on the head and mesosoma, a shorter, convex scutellum, an elongate propodeum and metapostnotum, long wings, with a higher number of hamuli, and by an elongate metasoma, with an unusually long first tergum. The single included species, Plectoplebeia nigrifacies comb. nov., is known only from the Bolivian Yungas, an ecoregion extending from west-central Bolivia to southeastern Peru.
