Diagnosis.

This species most closely resembles Atoposega lineata and Atoposega simulans based on the lack of fine dense U-shaped striae on metasomal tergum II. The banded wings resemble those of Atoposega rieki and Atoposega lineata . Atoposega thailandica can be distinguished from these species by the combination of flagellomere I 4 × as long as broad (versus 3 ×) and hindocellus separated by less than 1 diameter from the nearest eye margin.

Female description.

Body (Fig. 11): length 5-6 mm. Head: face (Fig. 6); scapal basin cross-ridged medially; frons with punctures contiguous; malar space 2.6 midocellus diameters long; head 0.9 × as long as wide; midocellus 2.2 midocellus diameters from ocular margin; hindocelli slightly further part than hindocelli and midocellus; hindocellus separated from ocular margin by 0.8 diameter; clypeus coarsely punctate and flattened apically; subantennal distance 0.9 midocellus diameters long; flagellomere I length 4 × breadth; flagellomere II 0.5 –0.6× as long as broad; flagellomere III 0.4 × as long as broad; flagellomere XI 1.8 × as long as broad. Mesosoma: pronotal, scutal and scutellar punctures large, contiguous, separated by longitudinal ridges; pronotum and scutum subequal in length; scutum with notauli deeper posteriorly than anteriorly; mesopleuron with large, contiguous punctures; metanotum 0.8 × as long as scutellum, medial enclosure coarsely areolate, with medial ridge; propodeal dorsal surface coarsely areolate, posterior surface with numerous cross-ridges on either side of longitudinal medial ridge; metapleuron and propodeal side coarsely cross-ridged; hindcoxa with two dorsal, longitudinal carinae, merging basally, elevated into basal tooth or angle; forefemur ventrally with tiny, contiguous punctures; hindfemur ventrally with longitudinal polished impunctate band. Metasoma: tergum highly polished, medial two-thirds impunctate, laterally with zone of small punctures, separated by 0.5-1.0 puncture diameters; tergum II medial third polished impunctate on anterior half of tergum, lateral third punctate, with punctures separated by 0.5-1.0 puncture diameters, becoming slightly striatiform laterally; terga III-IV with dense, small, contiguous punctures; sterna II-IV with punctures separated by 0.5-1.0 puncture diameter, punctures largest on II becoming progressively smaller on subsequent sterna. Color: head black; scape bicolored, red to light brown ventrally, blackish dorsally; pedicel and flagellomere I pale red to brown; flagellum blackish; mesosoma 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 brassy tints, sternum I may be brownish; wing membrane bicolored, membrane and setae dark brown tinted, with broad pale band across wing at stigma.
