( Figs 30, 75, 120)

Description. FEMALE (holotype). Body length 6.9 mm. LFW 4.1 mm.

Coloration. Head dark castaneous almost black; scape, pedicel, flagellum dark castaneous and mandible dark castaneous; palpi light castaneous; mesosoma dark castaneous almost black; tegula castaneous; wing venation dark castaneous; coxae dark castaneous; trochanters castaneous; femora castaneous; tarsi light castaneous; metasoma dark castaneous.

Head ( Fig. 30). Head wider than long, globoid in profile; gena weakly concave in profile. Mandible evenly wide, teeth sub-equal, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe angulate, median concavity of median clypeal lobe absent, 0.03 LH, well marked off from frons, median carina present, 0.23 LH. Malar space conspicuous, 0.5 mandibular base. Antenna 2.05 mm; first five antennomeres in ratio of about 12:14:12:12:12; flagellomere 1 1.1 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 0.17 LH. Eye not protuberant, 0.58 LH, with sparse hairs, located more laterally, lower margin without strong depression. Frons coriaceous-punctate. WH 1.36 LH. WF 0.63 WH. WF 1.36 HE. OOL 0.67 WOT. VOL 0.22 HE. Distance from posterior ocellus to vertex crest 0.2 DAO. Ocelli large, DAO 0.13 WF, ocellar triangle not compact, distance between posterior ocelli 1.9 DAO, anterior ocellus surpassing imaginary top eye line, posterior ocellus reaching vertex. Vertex concave, long setae, 0.32 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina, angulate, low.

Mesosoma (Fig. 75). Pronotal disc coriaceous-punctate, 0.37 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, 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.

Wings. Macropterous. Forewing ( Fig. 120) 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 0.83 Rs a; M vein 1.28 Rs a; Rs a subperpendicular to anterior margin of forewing; stigma rectangular; distal stigmal margin truncate. Hind wing with five distal hamuli, last hamulus discontinuous each other.

Legs. Profemur swollen, 0.49 as wide as long. Metacoxa with median region 0.64 as wide as long. Metacoxal projection in dorsal region conspicuous, apex rounded.

Metasoma. 0.35 as wide as long.

MALE. Unknown.

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.
