Vertex straight, long setae, 0.21 LH, temple profile slightly convergent in dorsal view, with corner convex, not projected posterolaterad. Hipostomal carina arched, low.

Mesosoma (Fig. 61). Pronotal collar regular-sized. Pronotal disc coriaceous-punctate, long, 0.5 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 0.90 length pronotal disc. Scutellum coriaceous-punctate, 0.81 length pronotal disc, almost flat in profile, posterior margin almost straight medially, scutellar pit elliptical, narrowed, distant each other 9.0 its own diameter. 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 0.75 length propodeal disc, incomplete posterad; discal carina 0.20 length propodeal disc, parallel to median carina, straight; space between median and discal carina imbricate and confused-rugulose. Mesopleuron with subtegular furrow elliptical; 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 evident.

Wings. Macropterous. Forewing ( Fig. 106) with 1M cell subpentagonal; 1M and 1R1 cells not aligned basally; C cell evenly narrow; 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 entirely on anterior margin of forewing; Cu b absent;

Legs. Profemur very swollen, 0.68 as wide as long. Metacoxa with median region 0.7 as wide as long. Metacoxal projection in dorsal region conspicuous, apex sharpened.

Metasoma. 5.0 as wide as long, ventral carina of petiole present.

MALE. Unknown.

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

Variation. Body length 4.52–8.57 mm; LFW 4.04–5.00 mm; clypeus and pronotal disc short to moderately long.

Remarks. This species is similar to E. baada   sp. nov. by having the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the clypeus with median clypeal lobe truncate and without median carina. However this species has the vertex crest slightly concave, the head nearly subtriangular in profile, the eyes large, the pronotal disc without anterior median pit, apical margin of pronotal disc nearly straight, whereas E. baada   sp. nov. has the vertex crest slightly convex, the head not subtriangular in profile, the eyes smaller, the pronotal disc with anterior median pit, the apical margin of pronotal disc convex.
