Scutellum polished, 0.7 length pronotal disc, almost flat in profile, posterior margin almost straight medially, scutellar pit elliptical, narrowed, distant each other 10.5 its own diameter. Polished and shining inside. Metanotum with median region almost flat, coriaceous-puncticulate, lower than scutellum in profile, with fovea oval laterally. Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.49 length propodeal disc, incomplete posterad; discal carina 0.23 length propodeal disc, parallel to median carina, straight; space between median and discal carina 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. 105) with 1M cell subpentagonal; 1M and 1R1 cells aligned basally; C cell widening distally; 1R1 cell present, slightly longer than 2R1 cell, evenly wide; Rs b straight; 2R1 cell 0.16 LFW; distal margin of Rs c angulate; r-rs vein inclined; R1 b arching distally; Cu b absent; Rs+M vein 1.3 Rs a; M vein 1.11 Rs a; Rs a slightly inclined toward tegula; stigma rectangular; distal stigmal margin truncate.

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

Variation. Body length 7.14–9.04 mm; LFW 4.76–5.24 mm; pronotal disc ill-defined to well-defined; parapsidal furrow inconspicuous; median carina slightly longer than half length of pronotal disc to complete (when it reaches the propodeal declivity).

Remarks. This species is similar to E. ceciliae Terayama   by having the body robust, the clypeus projected without median carina and the Rs b of forewing almost straight. However this species has the clypeus broadly truncate, the eyes not protuberant, the vertex crest straight, the pronotal disc with anterior median pit, whereas has the clypeus truncate, the eyes protuberant, the vertex crest strongly concave, the pronotal disc without anterior median pit.
