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

Head ( Fig. 28 View FIGURES 27–38 ). Head wider than long, subtriangular in profile; gena weakly concave in profile. Mandible with base wider than apex, lowermost tooth larger than upper ones, lower tooth curved inward, lower margin strongly setose. Clypeus coriaceous-punctate, median clypeal lobe subangulate, median concavity of median clypeal lobe absent, 0.09 LH, well marked off from frons, median carina present, 0.1 LH. Malar space conspicuous, 0.21 mandibular base. Antenna 1.76 mm; first five antennomeres in ratio of about 11:11:11:11:11; flagellomere 1 1.57 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 0.12 LH. Eye posterior ocellus to vertex crest 0.33 DAO. Ocelli small, DAO 0.08 WF, ocellar triangle not compact, distance between posterior ocelli 4.5 DAO, anterior ocellus surpassing imaginary top eye line, posterior ocellus almost reaching vertex. Vertex straight, long setae, 0.41 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected postero-laterad. Hipostomal carina, angulate, low.

Mesosoma ( Fig. 73 View FIGURES 66–74 ). Pronotal disc coriaceous-punctate, 0.5 as long as wide, anterior corner rounded, posterior margin concave medially, pronotal disc without short longitudinal furrow. Parapsidal furrow wholly conspicuous. Notauli convergent posterad. Mesoscutum 0.41 length pronotal disc. Scutellum coriaceous-punctate, 0.91 length pronotal disc, almost flat in profile, scutellar pit elliptical, narrowed, distant each other 11.7 its own diameter. Dorsal axillar surface with fovea oval. Metanotum with median region almost flat, lower than scutellum in profile, with fovea oval laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.82 length propodeal disc, incomplete posterad; discal carina 0.40 length propodeal disc, converging posterad, straight; space between median and discal carina confused-rugulose. Lateral of propodeum predominantly coriaceous, anterior region with pits equally deep, oval, coriaceous, evenly narrow posterad, 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 heart-shaped; median suture not evident.

Wings. Macropterous. Forewing ( Fig. 118 View FIGURES 113–122 ) 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 0.17 LFW; distal margin of Rs c angulate; r-rs vein almost vertical; R1 b arching distally; Cu b absent; Rs+M vein 1.4 Rs a; M vein 1.0 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, 0.53 as wide as long. Metacoxa with median region 0.73 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened.

Metasoma. 0.24 as wide as long.

MALE. Unknown.

Distribution. Australia (South Australia).

Variation. Body length 4.46–6.90 mm; LFW 2.39–4.28 mm; median clypeal lobe slightly projected; discal carina of propodeal disc as long as half length of propodeal disc; veins of forewing dark castaneous.

Remarks. This species is similar to E. inggarda sp. nov. by having the area between the anterior margin of eyes and demarkation of median clypeal lobe short, the eyes large, median clypeal lobe angulate, the vertex crest straight, the discal carina of propodeal disc as long as half length of propodeal disc, the C cell of forewing conspicuous apically. However this species has the head subrectangular in profile, the concavity of gena shallow, whereas E. inggarda sp. nov. have the head subtriangular in profile, the concavity of gena strongly concave.
