Distribution. Australia (Tasmania, New South Wales).

Variation. Body length 4.29–5.48 mm; LFW 3.90–4.30 mm; median clypeal lobe slightly projected, vertex crest almost straight.

Remarks. This species is similar to E. insulana by having the median clypeal lobe angulate, the discal carina and median carina of propodeal disc present, the hind wing with four distal hamuli, the posterior margin of hypopygium angulate and the lateral stalk of hypopygium conspicuous, but it differs from it by having the apical margin of digitus spinose, the posterior margin of hypopygium with teeth wide and one distant from the other, whereas E. insulana has the apical margin of digitus not spinose, the posterior margin of hypopygium very close to each other.

It is also similar to E. antakirinja sp. nov. because both species have the eyes small, the ocelli large, the median carina of median clypeal lobe strongly elevated, the median carina of propodeal disc long, the posterior margin of hypopygium angulate and the genitalia with paramere doble. However this species has the vertex crest of head slightly convex, the region between the anterior margin of eye and antennal torulus straight, the area between the anterior margin of eyes and demarkation of median clypeal lobe short, the Rs c of forewing convex, the lateral stalk of hypopigium long, the parameres of genitalia long, whereas E. antakirinja sp. nov. has the vertex crest of head straight, the region between the anterior margin of eye and antennal torulus concave, the area between the anterior margin of eyes and demarkation of median clypeal lobe long, the Rs c of forewing angulate medially, the lateral stalk of hypopigium very short, almost inconspicuous and the parameres of genitalia short.
