Diagnosis
This species is closest to Atoposega rufithorax based on dimensions of the flagellomeres, length of the subantennal distance and lack of a posterior propodeal enclosure. It can be distinguished from Atoposega rufithorax by the presence of an elevated, medial metanotal ridge, the scutellum elevated above metanotum and separated from the metanotum by a deep notch in side view, and clypeal apex truncate not broadly rounded as in Atoposega rufithorax.
Female description
Body (Fig. 10): length 3–5 mm. Head: face (Fig. 5); scapal basin coarsely, cross-ridged medially, with medial ridge; frons with punctures contiguous; malar space 3.5 midocellus diameters long; head 0.8× as long as wide in front view; midocellus 2.5 midocellus diameters from ocular margin; hindocelli further apart than midocellar-hindocellar distance; hindocellus separated from ocular margin by 0.8× hindocellar diameter; clypeus flat apicomedially, punctures small, irregular; subantennal distance 1.0–1.2 midocellus diameters: flagellomere I length 3.8× breadth; flagellomere II as 0.8× as long as broad; flagellomere III 0.6× as long as broad, flagellomere XI 1.6× as long as broad. Mesosoma: Pronotal, scutal and scutellar punctures 0.5–1.0 puncture diameter apart, finely, densely striate between punctures; pronotum as long as scutum in length; scutal notauli deeper posteriorly than anteriorly, extending entire length of scutum; mesopleuron without depression from pronotal lobe to scrobe, punctures large, deep, contiguous; metanotum 0.9× as long as scutellum, medial enclosure areolate, with strongly elevated medial ridge; propodeal dorsal surface coarsely areolate, posterior surface with medial enclosure with elevated marginal carina particularly well-developed dorsally, with longitudinal medial ridge and transverse ridges; metapleuron and propodeal side densely cross-ridged; forefemur and hindfemur densely punctate-reticulate ventrally. Metasoma: terga I and II polished and impunctate medially, lateral third with fine longitudinal scratches and punctures, punctures 1 puncture diameter apart, scratches merging posteriorly forming U-shape; terga III-IV with dense, contiguous tiny punctures; sterna II-IV with dense small punctures 0.5–1.0 puncture diameters apart, punctures smaller and somewhat denser on III-IV. 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, hindtibia black, with pale joints; propodeum black dorsally and posteriorly; metasomal segments black, terga with metallic green tints, sternum I may be brownish; wing membrane brown-tinted.
Etymology
The species name refers to the fine longitudinal scratches on the dorsum of the mesosoma.
