( Figures 7-8 )

Diagnosis. Yellow marks limited to trochanters; clypeus with a narrow median longitudinal, smoothly rough, polished area delimited by coarse punctures, slightly depressed on males; tentorial pit at level of lower tangent of compound eyes, clypeus weakly protuberant; metapostnotum finely reticulate; metatibia with reduced carina (ca. 2 DO).

Male: Apical margin of T7 almost straight with a short median angular projection; apical margin of S5 broadly emarginate medially ( Figure 8 D-E).

Description. Holotype female ( Figure 7 ): body length 10.7; forewing length 6.9; clypeus approximately 1.5 times as wide as long; ocellocular distance 2.6 OD; ocelloccipital distance 2.5 OD.

Color. Integument evenly bright metallic green including lateral margins of labrum, base of mandible, and anterior inner third of tegula; mandible, labrum, and apical margin of clypeus brownish. Posterior third of pronotum and surface below pronotal lobe light brown. Tegula translucent light brown, veins brown and wing membrane weakly brownish. Legs brownish with strong metallic green reflections. Reddish-brown bands on preapical margins of T2 and T3, interrupted in middle. Pale-yellow stripe on apical margin of outer surface of trochanters.

Pubescence. Mostly whitish, yellowish on labrum, mandible, tarsi, and apex of metasoma. Disc of propodeum with long hairs, areas with short and dense hairs intermingled with long hairs more evenly distributed. T4 and T5 covered with short spatulate whitish setae.

Integumental surface. Punctation denser and conspicuous on lower half of head. Mesosoma with finer and sparser punctation leaving large, polished areas between the punctures, especially on mesoscutum and lower portion of mesepisternum. Metepisternum with a small, polished area near propodeal spiracle. Metapostnotum finely reticulate. Disc of T1-T3 with fine and sparse punctation.

Structure. Tentorial pit at the level of lower tangent of compound eyes, clypeus weakly protuberant in lateral view. Preoccipital carina well developed. Lateral areas of pronotum with strong carina forming lamella. Metatibia with reduced carina. Graduli present on T2 to T4.

Allotype male ( Figure 8 ). Similar to female except as follows: three translucent brown spots at base of labrum; yellow marks on disc of labrum, base of mandible, and a narrow horizontal stripe on apical margin of clypeus; small subtriangular spots on lower paraocular area, over lateral expansions of clypeus absence of spatulate setae on metasoma; lateral margins of T6 with long hairs as long as hairs of T7; apical margin of T7 with long and plumose hairs on sides delimiting a median tuft of shorter and blacker simple hairs; disc of clypeus with a median longitudinal depression delimited by coarse punctures; metatibia with vestigial carina; apical margin of T7 almost straight with a short median angular projection; preapical margin of S5 without acute processes, apical margin broadly emarginate medially; apical margin of S6 with two acute projections, medially with a "star-shaped" notch ( Figure 8F ); genital capsule as in figure 8G. Body length 9.7; forewing length 6.2; clypeus approximately 1.3 times as wide as long; ocellocular distance 2.5 OD; ocelloccipital distance 2 OD. Male terminal structures as in Figure 8 D-G.

Type material. HOLOTYPE ♀. COLOMBIA: Amaz. [Amazonas], Tarapaca , 14 - 30.ix.1976, M. Cooper, B.M. 1976-727 ( NHMUK) . ALLOTYPE ♂. PERU: Loreto, Pucallpa , 20.x.1961, J.M. Schunke, B.M. 1961-64 ( NHMUK). All specimens are in excellent conditions .

Distribution. Colombia (Amazonas); Peru (Pucallpa).

Etymology. The name of this species is a tribute to our esteemed colleague, in memoriam, Professor Dr. Jesus Santiago Moure (popularly known in the academic community as Padre Moure) due to his valuable contributions to the knowledge of bee taxonomy, especially from the Neotropics.
