The Neotropical stingless bees genus Dolichotrigona Moure, 1950, is revised. Seven new species are described: D. mendersoni sp. nov. (Brazil: AM, AC, RO), D. clavicornis sp. nov. (Brazil: AC), D. rondoni sp. nov. (Brazil: RO), D. tavaresi sp. nov. (Brazil: AM, AC), D. browni sp. nov. (Brazil: RO, AC, MT; Peru, Equador, Bolivia), D. moratoi sp. nov. (Brazil, AM, AC) and D. chachapoya sp. nov. (Peru). The holotype of Trigona martinezi Brèthes, 1920, and the lectotype of Melipona longitarsis Ducke, 1916 - herein designated -, were examined and redescribed. Trigona schulthessi Friese, 1900, was interpreted based on the literature. Identification key for species and illustrations of the main diagnostic characters are presented.
