Parapsidal furrow conspicuous only at third posterior part. Notauli convergent posterad. Mesoscutum 1.1 length pronotal disc. Scutellum coriaceous-punctate, 0.95 length pronotal disc, almost flat in profile, posterior margin almost straight medially, scutellar pit almost circular, narrowed, distant each other 12.3 its own diameter. Dorsal axillar surface with fovea subrectangular. Metanotum with median region high, coriaceous-puncticulate, as high as scutellum in profile, with fovea oval laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.96 length propodeal disc, complete posterad; discal carina 0.40 length propodeal disc, parallel to median carina, converging posterad, straight; space between median and discal carina confused-rugulose. Mesopleuron with subtegular furrow oval; mesepimeral suture almost inconspicuous posterad; mesopleural epicoxal lobe inconspicuous. Propleuron with sequence of foveae from anterior margin of prosternum until cervical collar absent. Prosternum with median excavation complete, median suture present. Mesopectus with posterior depression composed by two large foveae almost fused; median suture evident.

Distribution. Australia (South Australia, Queensland, New South Wales).

Remarks. This species has features common to most species of the genus, such as, the eyes large, the median clypeal lobe angulate with median carina extending to the frons, the vertex crest straight. However this species has the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the ocelli small, the posterior ocelli distant to each other, the vertex crest with very long setae, the Rs b of forewing clearly angulate, the 1R1 cell of forewing slightly dilated medially, the C cell of forewing evident along almost its entire length.
