Vertex straight, long setae, 0.29 LH, temple profile approximately parallel in dorsal view, with corner angulate, not projected postero-laterad. Hipostomal carina straight, low.

Mesosoma (Fig. 63). Pronotal disc coriaceous-punctate, 0.4 as long as wide, anterior corner rounded, posterior punctate, 0.65 length pronotal disc, almost flat in profile, posterior margin convex 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, foveolate, lower than scutellum in profile, with fovea oval laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.95 length propodeal disc, complete posterad; discal carina 0.67 length propodeal disc, straight, followed by depressed narrow area, foveolate; space between median and discal carina confused-rugulose. Mesopleuron with subtegular furrow elliptical; 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 absent. Mesopectus with posterior depression heart-shaped; median suture evident.

Wings. Macropterous. Forewing ( Fig. 108 View FIGURES 103–112 ) 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 straight; 2R1 cell 0.15 LFW; distal margin of Rs c convex; r-rs vein strongly inclined; Costal cell widening distally; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 1.75 Rs a; M vein 1.67 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, 0.48 as wide as long. Metacoxa with median region 0.85 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened.

Metasoma. 3.0 as wide as long, ventral carina of petiole present.

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

Variation. Body length 4.86–7.14 mm; LFW 3.76–4.54 mm; discal carina less than half length of propodeal disc; color of posterior tergites of metasoma castaneous to dark castaneous; Cu b of forewing present, but almost vestigial.

Remarks. This species is similar to E. barada sp. nov. by having the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the head with large eyes and subtriangular in profile. However this species has the median carina of clypeus extending to the frons, the median clypeal lobe angulate, the gena strongly concave in profile, whereas E. barada sp. nov. has the median clypeal lobe truncate without median carina, the gena weakly concave in profile.
