Megalopta atlantica Santos and Silveira, 2009:14 . Holotype male, Brazil: Minas Gerais, Ipanema (DZUP, examined).

Diagnosis

The male differs from M. guarani sp. n. and M. karitiana sp. n. by the medial protruding process of S4 digitiform in lateral view and by rugulosities present in central portion of basal area of metapostnotum; from M. mapinguari sp. n. by the mesosoma homogeneously black to brown and by medial protruding process of S4 lacking setae in the apex; from M. xavante sp. n. by the integument black and by presence of rugulosities in the basal area of metapostnotum. This latter character also distinguishes M. atlantica from M. purpurata .

Description

Male. (15) Scape with diameter gradually enlarging toward the apex. (16) Flagellum blackish brown, F1–F11 not differing in diameter, F2 about two-thirds of F 3 in length, F6–F11, in anterior view, with the anterior and posterior margins flat (Figures 9F, 10B), in posterior view with basal glabrous area at same level of remaining surface. (17) Metanotum with integument, in dorsal view, not hidden by short plumose pilosity (Figure 11E). (18) Basal area of metapostnotum blackish brown; its length half of that metanotum; with longitudinal rugulosities present in central area, the rugulosities oblique towards the sides (Figure 11E). (19) Metepisternum with sparse pilosity, integument visible through pilosity; posterior upper margin of metepisternum unmodified, lacking a velvety process. (20) 1st and 2nd tarsomeres of foreleg with longest simple setae shorter than the summed length of the three apical tarsomeres. (21) S3 with longitudinal sulcus, posterolateral margin notched. (22) S4 with medial protruding process, profile of process digitiform in lateral view; basal portion glabrous; posterolateral margin notched, notch not extending to basal half of sclerite.
