Diagnosis.F2 longer than F3. Mesoscutal midlobe and mesoscutellum, including axillula, alveolate. Mesoscutal midlobe with a pair of reddish areas anteriorly. Axilla anteriorly (dorsally) areolate, without distinct longitudinal carinae. Petiole in females not extending beyond hind coxal apex. This species is similar to others with an areolate axillula and partially reddish mesoscutum. It differs from O. arimbomein lacking longitudinal axillular carinae ( Fig. 159), and differs from O. rikrain having a dark brown antennal flagellum ( Fig. 157).
Description. Female.Length 2.5–3.56 mm. Color:Head and mesosoma dark green to blue, with red to yellow luster. Pedicel brown; anellus brown; flagellum brown. Coxae brown; fore femur mostly brown, tips pale; mid and hind femora yellow. Fore wing hyaline; venation pale brown. Petiole green; gaster brown. Head:Head width:head height 1.2–1.3; face reticulate; longitudinal groove between eye and torulus absent; eyes bare; inter-ocular distance:eye height 1.3–1.8; malar space:eye height 0.6–0.9; supraclypeal area longer than broad, smooth to weakly sculptured; clypeus smooth to weakly sculptured. Flagellum length:head height 1.7; F2 3.4–4.0× as long as broad, 1.3–1.9× as long as F3; following funiculars subequal in width, progressively shorter. FIGURES 155–162. Orasema pirca. ♀: 155.Habitus. 156.Head. 157.Antenna, with F2 and F6–F7 inset. 158.Mesosoma, dorsal view. 159.Axillula. 160. Stigma and postmarginal vein (holotype). FIGURES 161–162. Orasema pirca. ♀: 161.Propodeum. 162.Petiole. Mesosoma:Mesosoma length:height 1.3–1.6; mesoscutal midlobe areolate, with minute setae; lateral lobe areolate to areolate-reticulate. Axilla areolate to areolate-reticulate; mesoscutellar disc areolate; frenal line irregularly foveate; frenum areolate; axillular groove anteriorly absent, broad and foveate posteriorly; axillula areolate. Propodeum with irregular median carina; propodeal disc areolate to areolate-reticulate; callus reticulate, with 3–5 setae. Mesepisternum reticulate to areolate-reticulate laterally, smooth ventrally, broadly rounded anterior to mid coxa. Upper mesepimeron smooth; lower mesepimeron areolate-reticulate; transepimeral sulcus distinct. Metepisternum laterally reticulate to areolate-reticulate. Hind coxa 1.7–2.3× as long as broad; hind femur 7.1–9.0× as long as broad. Fore wing 2.3–2.8× as long as broad, 3.7–4.2× as long as mesothorax; stigma with 4 widely separated sensilla forming an L-shape; Hind wing costal cell with 1 or 2 irregular rows of setae. Metasoma:Petiole 2.4–3.0× as long as broad, 0.7–0.9× as long as hind coxa, areolate to areolate-reticulate, anterior carina moderate. Antecostal sulcus with weak sculpture; acrosternite posteriorly angulate. Male. Unknown.
Distribution. Bolivia, Ecuador, Peru, Venezuela.
