Malar space conspicuous, 0.33 mandibular base. Antenna 1.81 mm; first five antennomeres in ratio of about 13:11:13:13:13; flagellomere 1 1.44 longer than wide, flagellar pubescence dense, with few outstanding erect setae. Region between torulus and eye straight. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.14 LH.

Ocelli small, DAO 0.08 WF, ocellar triangle not compact, distance between posterior ocelli 3.25 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, long setae, 0.22 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina arched, low.

Mesosoma (Fig. 80). Pronotal disc coriaceous-punctate, 0.3 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow conspicuous only at third posterior part. Notauli convergent posterad. Mesoscutum 1.17 length pronotal disc. Scutellum coriaceouspunctate, 1.1 length pronotal disc, almost flat in profile, posterior margin almost straight medially, scutellar pit elliptical, narrowed, distant each other 10.0 its own diameter. Dorsal axillar surface with fovea oval. Metanotum with median region almost flat, 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 0.88 length propodeal disc, incomplete posterad; discal carina 0.14 length propodeal disc, parallel to median carina, straight; 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.

Wings. Macropterous. Forewing ( Fig. 125 ) with 1M cell subpentagonal; 1M and 1R1 cells not aligned basally; C cell widening distally;1R1 cell present, distinctly longer than 2R1 cell, wider medially; Rs b convex; 2R1 cell 0.15 LFW; distal margin of Rs c convex; r-rs vein inclined; R1 b arching distally; Cu b absent; Rs+M vein 1.45 Rs a; M vein 1.38 Rs a; Rs a subperpendicular to anterior margin of forewing; stigma rectangular; distal stigmal margin truncate. Hind wing with five distal hamuli, last hamulus adjacent each other.

Legs. Profemur swollen, 0.55 as wide as long. Metacoxa with median region 0.6 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.22 as wide as long, except first two tergites, ventral carina of petiole present.

MALE. Unknown.

Distribution. Australia (New South Wales, Australian Capital Territory, Western Australia).

Variation. Body length 6.20–6.67 mm; LFW 4.29–4.77 mm; notauli slightly convergent posterad; Rs b slightly convex; discal carina of propodeal disc diagonally inclined.

Remarks. This species has features common to most species of the genus by having the eyes large, the median clypeal lobe angulate and with median carina extending to frons, the vertex crest straight. However this species has some peculiar characteristics such as the body robust, the pronotal disc short but very wide a strong and clear narrowing of C cell of forewing, slighty conspicuous in apical region.
