Head ( Fig. 31). Head as long as wide, globoid in profile; gena weakly concave in profile. Mandible with base wider than apex, two lowermost teeth larger than upper ones, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe truncate, median concavity of median clypeal lobe present, 0.11 LH, well marked off from frons, median carina present, 0.1 LH. Malar space conspicuous, 0.5 mandibular base. Antenna 2.0 mm; first five antennomeres in ratio of about 12:12:12:12:12; flagellomere 1 1.33 longer than wide, flagellar pubescence dense, with many outstanding erect setae. Region between torulus and eye slightly concave. Area between the anterior margin of eyes and demarkation of median clypeal lobe 0.16 LH. Eye not protuberant, 0.48 LH, with sparse hairs, lower margin without strong depression. Frons coriaceous-punctate. WH 1.0 LH. WF 0.77 WH. WF 1.31 HE. OOL 1.14 WOT. VOL 0.46 HE. Distance from posterior ocellus to vertex crest 0.33 DAO. Ocelli small, DAO 0.08 WF, ocellar triangle not compact, distance between posterior ocelli 3.5 DAO, anterior ocellus not surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, short setae, 0.20 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina arched, low.

Mesosoma (Fig. 76). Pronotal disc coriaceous-punctate, 0.44 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 1.1 length pronotal disc. Scutellum coriaceous-punctate, 1.0 length pronotal disc, almost flat in profile, posterior margin almost straight medially, scutellar pit elliptical, narrowed, distant each other 12.0 its own diameter. Dorsal axillar surface with fovea almost circular. 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 0.85 length propodeal disc, incomplete posterad; discal carina 0.40 length propodeal disc, converging posterad, straight; space between median and discal carina confused-rugulose. Mesopleuron with subtegular furrow oval; mesepimeral suture wholly conspicuous, 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 not evident.

Wings. Macropterous. Forewing ( Fig. 121) with 1M cell subpentagonal; 1M and 1R1 cells not aligned basally; C cell widening distally;1R1 cell present, distinctly longer than 2R1 cell, evenly wide; 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 1.1 Rs a; M vein 1.29 Rs a; Rs a subperpendicular to anterior margin of forewing; stigma rectangular; distal stigmal margin truncate. Hind wing with four distal hamuli, last hamulus discontinuous each other.

Legs. Profemur swollen, 0.52 as wide as long. Metacoxa with median region 0.6 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.34 as wide as long.

Distribution. Australia (South Australia, Western Australia, New South Wales, Tasmania).

Variation. Body length 4.70–6.21 mm; LFW 3.33–4.76 mm; median clypeal lobe subangulate, almost rounded and almost without projection.

Remarks. This species is very different of the others by having the median clypeal lobe broad, subangulate, bifurcating anterad and the distal region of Rs c of forewing strongly convex.
