(16) Flagellum blackish; F1–F11 not differing in diameter; F2 about two-thirds of F 3 inlength ( Figure 9D); F6–F11, in anterior view, with the anterior and posterior margins flat, 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 pillosity ( Figure 11C). (18) Basal area of metapostnotum metallic green, its length 0.5× that of metanotum, longitudinal rugulosities present in the mid portion ( Figure 11C). (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 ( Figure 11B). (22) S4 with medial protruding process, profile of process digitiform in lateral view ( Figure 11B); basal portion glabrous; posterolateral margin notched, notch not extending to basal half of sclerite.   Measurements Approximate body length: (12.4); intertegular distance: (3.8); maximum width of head: (2.9); length of forewing with tegula: (10).   Female.Unknown.    Type material    Holotypemale( DZUP): BRAZIL. Acre: ‘Faz. Catuaba – UFAC\ armadilha luminosa\ capoeira’.    Comments The collecting date of the typespecimen is unknown. The species can be easily recognized by intense metallic green reflections, sometimes mixed with black tints in integument, except for predominantly blackish metasoma.    Distribution  BRAZIL. Acre: Rio Branco ( Figure 15D).    Etymology The specific epithet honours the ‘Mapinguari’, used here as a noun in apposition. The ‘Mapinguari’, a Brazilian folklore character, is popularly known as a monster that lives in the Amazon Rainforest. 2849237487 DZUP, UFAC Brazil Acre 49 624 1 Acre holotype
