Holotype male, Brazil : Amazonas , Tefé (‘Ega’) (BMNH, not directly examined). Diagnosis The male differs from those of M. guarani sp. n. and M. karitiana sp. n. by the digitiform medial protruding process of S4, in lateral view; from M. mapinguari sp. n and M. xavante sp. n. by the mesosoma homogeneously blackish ( Figures 11F , 12C ); also distinguished from M. mapinguari by medial protruding process of S4 lacking setae in the apex; from M. atlantica by the absence of rugulosities in basal area of metapostnotum ( Figure 12C ). Description Male. (15) Scape missed. (16) Flagellum missed ( Figure 10A ). (17) Metanotum with integument, in dorsal view, not hidden by short plumose pilosity ( Figure 11F ). (18) Basal area of metapostnotum blackish; its length less than half of metanotum ( Moure 1958 ); smooth, without rugulosities ( Figure 12C ). (19) Metepisternum with sparse pilosity, integument visible through pilosity; posterior upper margin of metepisternum unmodified, lacking a velvety process. (20). 1st and 2nd tarsomere of foreleg unobserved. (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. Female. Unknown. Comments The type was not examined directly, but through photographs obtained from the British Museum ( BMNH ). Its inclusion in the byroni species group was based on the following features: body coloration without metallic green reflections and S 4 in basal area with a digitiform medial protruding process. Some characteristics of this species were extracted from Moure’ s (1958) redescription . Distribution BRAZIL . Amazonas: Tefé ( Figure 15D ).
