Abstract
ABSTRACT A distinctive new species of the Neotropical stingless bee genus Paratrigona Schwarz from northeastern Brazil, previously considered as a variation within P. lineata by Camargo and Moure (1994), is described and illustrated. Paratrigona intermedia Oliveira, Madella-Auricchio & Freitas sp. nov. belongs to the lineata group. It is easily distinguished from its congeners by the pattern of body pubescence, especially by the absence of erect setae on the mesoscutum and disc of the mesoscutellum, and the presence of erect setae on the apical border of the mesoscutellum (dorsal and ventral surfaces) and sparse short erect setae on the upper 2/3 of the mesepisternum. The lectotype designation for Melipona lineata Lepeletier, 1836 is provided along with notes on its morphology and the concept of Paratrigona lineata is changed to differentiate it from the new species described here. Paratrigona lineata (Lepeletier, 1836), P. glabella Camargo & Moure, 1994 and P. incerta Camargo & Moure, 1994 are illustrated to facilitate comparisons with the new species. An updated key to the lineata species group, including the new species, is also provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:3FA139B8-1FDA-459A-8189-F3785AE25BF1 http://www.zoobank.org/urn:lsid:zoobank.org:act:9D6A8CD7-D8F6-44B2-81CF-E12C01FA0DCD
