Propodeal disc wider than long; anterior margin without foveolate or transverse furrow; median carina 0.97 length propodeal disc, complete posterad; discal carina 0.75 length propodeal disc, surpassing half length of propodeal disc, converging posterad, straight; space between median and discal carina confused-rugulose. Mesopleuron with subtegular furrow oval; 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 heart-shaped; median suture evident.

Wings. Macropterous. Forewing ( Fig. 109 ) with 1M cell subrectangular; 1M and 1R1 cells aligned basally; C cell widening distally; 1R1 cell present, distinctly longer than 2R1 cell, wider medially; Rs b convex; 2R1 cell 0.13 LFW; distal margin of Rs c convex; r-rs vein inclined; R1 b entirely on anterior margin of forewing; Cu b absent; Rs+M vein 0.85 Rs a; M vein 1.0 Rs a; Rs a subperpendicular to anterior margin of forewing; stigma rectangular; distal stigmal margin truncate.

Distribution. Australia (Australian Capital Territory, Queensland).

Variation. Body length 4.76–7.85 mm; LFW 4.04–4.29 mm; setae of body dense to very dense; clypeus slightly projected; discal carina of propodeal disc with posterior region straight.

Remarks. This species is similar to E. barada sp. nov. by having the head subtriangular in profile, the eyes large, the clypeus with median clypeal lobe with median carina present. However this species has the area between the anterior margin of eyes and demarkation of median clypeal lobe short, the gena not clearly concave in profile and the discal carina of propodeal disc almost as long as median carina, whereas E. barada sp. nov. has the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the gena clearly concave in profile and the discal carina of propodeal disc almost absent.
