Megalopta piraha sp. n.

( Figures 4B View Figure 4 , 5B, C, 5F View Figure 5 , 10D View Figure 10 , 12E View Figure 12 , 13E View Figure 13 , 15C View Figure 15 )

Diagnosis

It differs from M. yanomami sp. n. by the basal area of metapostnotum without defined external sulcus delimiting the longitudinal rugulosities, the integument light green ( Figure 4B View Figure 4 , 12E View Figure 12 ); the male is also distinguished by the scape enlarged gradually in direction to the apex ( Figure 13E View Figure 13 ) and by flagellomeres without depressed and glabrous area ( Figure 10D View Figure 10 ).

Description

Female. (1) Mandible bidentate and with supplementary teeth. (2) Labral elevation with the flattened surface. (3) Clypeus with surface between punctures on basal and central area microreticulate.(4) Central portion of supraclypeal area with dense punctation, punctures separated by <1 pd, punctation becoming sparser in the lower portion (≥ 1 pd). (5) Antenna reddish brown ( Figure 5B View Figure 5 ). (6) Upper frons flat, not strongly declivous toward sulcus around median ocellus. (7) Ocellocular distance smaller than the F1 length ( Figure 5B View Figure 5 ). (8) Mesoscutum adjacent to the parapsidial line densely punctured, punctures contiguous on remainder of disc. (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 5F View Figure 5 ). (11) Basal area of metapostnotum reddish brown with green metallic tints, its length up to 0.8× that of metanotum, centrally with a single weak longitudinal rugulosity and a few shorter and slightly impressed ones in central portion, lateral surface smooth ( Figures 4B View Figure 4 , 5F View Figure 5 ). (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 sparsely punctured (≥ 1 pd), posterior marginal zone microreticulate between punctures. Male. (15) Scape with diameter gradually enlarging toward the apex. (16) Flagellum pale yellow ( Figure 13E View Figure 13 ), F1– F11 not differing in diameter; F2 about as long as F3 ( Figure 13E View Figure 13 ); F6–F11, in anterior view with the anterior and posterior margin depressed ( Figure 10D View Figure 10 ), 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. (18) Basal area of metapostnotum as in the female ( Figure 12E View Figure 12 ). (19) Metepisternum as in the female. (20) 1st and 2nd tarsomeres of foreleg with longest simple setae shorter than summed length of the three apical tarsomeres. (21) S3 with longitudinal sulcus, the 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: (13.0–14.8); maximum width of head: (3.4–4.3); intertegular distance: (3.6–4.4) mm; length of forewing with the tegula: (11.7–13.2).

Etymology

The specific epithet honours the ‘Pirahã’ or ‘Mura-Pirahã’, the name for an ethnic group of South American natives, descendents of the ‘Mura’, used here as a noun in apposition. The Pirahã inhabit a tract of lands traversed by the Marmelos river and almost the entire length of the Maici river, located in the municipality of Humaitá, in Amazonas, northern Brazil ( Gonçalves 2000).
