Head, antennae, and rostrum black; pronotum blackish brown with reddish orange stripe along lateral margins; connexivum completely reddish orange; scutellum concolorous with pronotum disk; corium black with basal third reddish orange; costal margin extending along connexivum and membrane black ( Fig 7A). Legs blackish brown. Venter blackish brown, with reddish orange stripe along lateral margins.

Head wider than long, mandibular plates longer than clypeus, rounded anteriorly and meeting in front of clypeus ( Fig 9J). Eyes globular, pedunculate. Ocelli well developed, closer to the eyes than to each other; interocellar distance 1.75 times distance of between eyes and ocelli ( Fig 9J). Labium four segmented, reaching anterior margin of meso coxae. First segment extending beyond head.

Remarks. This species was described from Laos and is known only from its type locality. Lis [ 24] mentioned that this species is present in India without any further information. In their world catalogue, Rolston et. al., [ 42] also mentioned China and Vietnam. Later, Kocorek [ 43] reported this species for the first time from Thailand. The specimens used here were donated by Marcos Roca-Cusachs, which were collected from the Laos and are identical to the holotype, as observed from images ( Fig 7A and 7F).
