Atoposega rieki (Krombein)

Atopogyne rieki Krombein 1957: 187. Holotype female; “Birmanie” (Myanmar) (PARIS).

Material examined.

Type unavailable for study; Myanmar.

Diagnosis.

Atoposega rieki most closely resembles Atoposega rufithorax and Atoposega striata based on the presence of fine dense longitudinal scratches on metasomal tergum II that join posteriorly, appearing broadly U-shaped. It can be distinguished from those species by the narrower subantennal distance, midocellus separated from the eye margin by less than two midocellar diameters, and banded wings.

Female description

(based on Krombein 1957). Body: length 6 mm. Head: face scapal basin transversely ridged medially; frons with punctures deep, contiguous; malar space 3.5 midocellus diameters long; head 0.9 × as long as wide; midocellus 1.3 midocellus diameters from ocular margin; ocelli arranged in isosceles triangle; hindocellus separated from ocular margin by 0.9 diameter; clypeus apicomedially indented; subantennal distance 0.7 midocellus diameters: flagellomere I length 3.7 × breadth; flagellomere II as long as broad. Mesosoma: pronotal, scutal and scutellar punctures 0.3-0.5 puncture diameter apart; pronotum 0.6 × as long as scutum, scutellum and metanotum combined; scutum with notauli well-developed anteriorly, broader posteriorly; mesopleuron with punctures contiguous to 0.5 puncture diameter apart; metanotum 0.9 × as long as scutellum; hindfemur minutely, finely rugulose ventrally. Metasoma: tergum I smooth, impunctate in medial half, lateral fourth finely, longitudinally carinate; tergum II with basal triangular, finely punctate area, laterally with dense, longitudinal carinae joined posteriorly into U-shape; terga III and IV finely, densely punctate; sterna II and III with large, dense punctures. Color: head black; antenna dark brown, except scape, pedicel and flagellomere I paler basally and apex of flagellomere I blackish; flagellomeres II-XI blackish; thorax red, except dorsal and posterior face of propodeum black; legs brown, except coxae, trochanters, femora and ibiae narrowly basally red, hindtibial apex and venter of hindfemur dark brown; metasoma shiny black, with faint green tints on terga I-II; wing membrane with alternating pale or brown bands.
