Diagnosis
This is one of three species, including Atoposega striata and Atoposega rieki, with fine dense longitudinal carinae on the sides of metanotal tergum II that join posteromedially. It can be distinguished from those species by the lack of an elevated, medial metanotal ridge, and the scutellum roughly planar with the metanotum and separated from the metanotum by a deep notch in side view.
Female description
Body (Fig. 9): length 3.5–4.5 mm. Head: face (Fig. 3); scapal basin finely, cross-ridged medially without discrete, longitudinal medial ridge; frons with punctures contiguous; malar space 3.5 midocellus diameters long; head 0.8× as long as broad in front view; midocellus 2.0–2.3 midocellus diameters from ocular margin; hindocelli further apart than midocellar-hindocellar distance; hindocellus separated from ocular margin by 0.7 hindocellar diameter; clypeus slightly concave apicomedially, punctures small, irregular; subantennal distance 0.8–0.9 midocellus diameters: flagellomere I length 5× breadth; flagellomere II 0.9× as long as broad; flagellomere III 0.7× as long as broad; flagellomere XI 1.5× as long as broad. Mesosoma: pronotal, scutal and scutellar punctures 0.5–1.0 puncture diameter apart, finely, densely striate between punctures; pronotum and scutum subequal in length; scutal notauli deep for entire length of scutum; mesopleuron without depression from pronotal lobe to scrobe, punctures large, deep, contiguous; metanotum 0.7× as long as scutellum, medial enclosure with large irregular punctures, without medial ridge; scutellum and metanotum subplanar in lateral view; propodeal dorsal surface coarsely areolate, posterior surface with carina margined medial enclosure, with longitudinal medial ridge; metapleuron and propodeal side with fine dense cross-ridging; forefemur with contiguous, tiny punctures dorsally and ventrally; hindfemur with dense tiny punctures dorsally, ventrally punctures becoming larger and reticulate. Metasoma: tergum I medial half impunctate, lateral fourth densely longitudinally striate, tergum II medially with impunctate band extending half length of tergum, becoming densely finely punctate extending laterally and becoming finely longitudinally striate, striae joining posteriorly becoming U-shaped (Fig. 7); terga III and IV with dense tiny, contiguous striatiform punctures; sterna II-IV with small punctures separated by 0.5–1.0 puncture diameters. Color: head black; scape bicolored, red to light brown ventrally, blackish dorsally; pedicel and flagellomere I pale red to brown; flagellum blackish; thorax and legs red, becoming paler ventrally, including all or most of lateral propodeum and propodeal teeth, propodeum black dorsally and posteriorly, hindtibia blackish to dark brown, with pale joints; metasomal segments black, terga with metallic bluish green tints, sternum I may be brownish; wing membrane brown-tinted, unbanded.
Etymology
The name refers to the red coloration of the thorax.
