( Figures 4C, 12F, 16B)
Diagnosis The female differs from those of M. cupreaand M. sodalisby basal area of metapostnotum with mid depression restricted to anterior half, not extending to posterior margin ( Figure 4C) and the male, by basal area of metapostnotum with shorter and weakly impressed longitudinal rugulosities ( Figure 12F).
Description Female.(1) Mandible bidentate and with supplementary teeth. (2) Labral elevation with lateral surface slightly raised in relation to central portion, the surface slightly bilobated basally. (3) Clypeus with surface between punctures on basal and central area microreticulated. (4) Central portion of supraclypeal area with sparse punctation, punctures separated by ≥1 pd. (5) Antenna reddish brown. (6) Upper frons flat, not strongly declivous toward sulcus around median ocellus. (7) Ocellocular distance smaller than the F1 length. (8) Mesoscutum, adjacent to parapsidial line densely punctured, punctures contiguous, punctation becoming sparser towards mesoscutal lip (<1 pd). (9) Scutellum with posterior margin raised in relation to anterior margin of metanotum. (10) Metanotum with integument, in oblique view, not hidden by short plumose pilosity ( Figure 4C). (11) Basal area of metapostnotum metallic green with reddish brown tints; its length at least 0.6× that of metanotum; with mid depression restricted to anterior half, not extending to posterior margin, longitudinal rugulosities restricted to central area ( Figure 4C). (12) Mesepisternum with contiguous punctation. (13) Metepisternum with sparse pilosity, integument visible through pilosity; posterior upper margin of metepisternum unmodified, lacking a velvety process. (14) T1 with dorsal surface of disc densely punctured (<1 pd), posterior marginal zone microreticulated between punctures. Male.(15) Scape with diameter gradually enlarging toward the apex. (16) Flagellum reddish brown; F1–F11 not differing in diameter; F2 about as long as F3; F6–F11, in anterior view with the anterior and posterior margins depressed, 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 12F). (18) Basal area of metapostnotum with shorter and weakly impressed longitudinal rugulosities ( Figure 12F). (19) Metepisternum as in the female. (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 triangular in lateral view; basal portion glabrous; posterolateral margin notched, notch not extending to basal half of sclerite. Measurements Approximate body length: (13.3–14.0); maximum width of head: (4.0–4.8); intertegular distance: (4.4–4.8); length of forewing with the tegula: (13.3–14.0).

Etymology The specific epithet honours the ‘Munduruku’, the name for an ethnic group of natives used here as a noun in apposition. Historically a people with a warrior tradition, the Munduruku culturally dominated the region of the valley of the Tapajós River, Brazil. Today, the wars they wage are to guarantee the integrity of their territory, threatened by pressures from the illegal activities of gold-panning, hydroelectric projects, and the construction of a great waterway on the Tapajós river ( Ramos 2003).
