Distribution. Australia (Tasmania).

Variation. Body length 4.04–5.24 mm; LFW 3.23–3.61 mm; pronotal disc short; lateral region of median carina of propodeal disc slightly depressed; median carina of propodeal disc short.

Remarks. This species is similar to E. djagaraga   sp. nov. by having the body texture coriaceous, the median clypeal lobe angulate, median carina of propodeal disc long, strongly high and discal carina of propodeal disc short. However this species has the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the eyes small, the ocelli small, the space between top of eye and vertex crest long, the Rs b of forewing approximately straight, whereas E. djagaraga   sp. nov. has the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the eyes large, the ocelli large, the space between top of eye and vertex crest not too long, the Rs b of forewing slightly angulate medially.
