Atoposega simulans Kimsey Figure 4

Atoposega simulans Kimsey 1986: 153. Holotype female; Malaysia: Pasoh Forest Res., Negri Sembilan (AEI).

Material studied.

Malaysia: Negri Sembilan; Thailand: Loei Prov., Phu Ruea NP; Prachuap Khiri Khan Prov., Khan Sam Rui Yot NP; Chaiyaphum Prov., Tai Tome NP, Pha Bin Ngan NP; Ubon Ratchathani, Pha Taem NP; Khon Kaen Prov., Nam Pong NP; Phetchabun Prov., Khao Kho NP, Nam Nao NP; Sakon Nakhon Prov., Phu Pham NP; in the months of December, January and April-October; 22 females were examined including the holotype (BME, AEI).

Diagnosis.

This species most closely resembles Atoposega lineata based on dimensions of the flagellomere I, the lack of longitudinal striae on metasomal tergum II and the hindocellus separated from the nearest eye margin by more than one diameter. Atoposega simulans can be distinguished from Atoposega lineata by the lack of lateral longitudinal scratches on metasomal tergum I and evenly brown-tinted wings.

Female description.

Body: length 2.5-5.0 mm. Head: face (Fig. 4); scapal basin with dense, coarse cross-ridges medially; frons with punctures large, contiguous; malar space 3.0-3.5 midocellus diameters long; head width 1.2 –1.3× length; midocellus 2.5 midocellus diameters from ocular margin; ocelli arranged in broad triangle; hindocellus separated from ocular margin by 1.2 diameters in dorsal view; clypeus flattened apically; subantennal distance 1 midocellus diameter long; flagellomere I length 3 × breadth; flagellomere II 0.6 × as long as broad. Mesosoma: pronotal, scutal and scutellar punctures large, coarse and contiguous; pronotum half as long as combined lengths of scutum, scutellum and metanotum; scutum with notauli deeper posteriorly than anteriorly; mesopleuron with large, deep, contiguous punctures; metanotum 0.6 –0.8× as long as scutellum, medial enclosure areolate, with strong medial, longitudinal ridge; propodeal dorsal surface coarsely areolate, posterior surface with medial enclosure with medial, longitudinal ridge and coarse cross-ridging laterally; metapleuron and propodeal side with coarse cross-ridging; forefemur with tiny, contiguous punctures dorsally, ventrally punctures 2-3 puncture diameters apart; hindfemur with tiny, contiguous punctures dorsally, ventrally punctures separated by 0.5-1.0 puncture diameters, with broad, longitudinal impunctate, polished band medially; metapleuron and propodeal side coarsely cross-ridged. 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; sternum II with tiny, widely separated punctures 5-10 puncture diameters apart; sterna III-IV punctures tiny, dense and contiguous to 0.5 puncture diameters apart. Color: head black; scape light brown; pedicel and flagellomere I whitish, except apex of flagellomere I blackish; flagellomeres II-XI blackish; thorax red, except dorsal and posterior face of propodeum black; legs and coxae red, except foretarsomeres, hindtibal apex and venter of hindfemur dark brown; metasoma shiny black, with faint green tints on terga I-II; wing membrane brown-tinted, with dark bands across wing at medial vein and apex of Rs alternating with pale bands.
