Readily distinguished from E. australis by its covering of short whitish hairs. Its elongated sclerotized ovipositor is very different in structure from the short spurred ovipositor of E. australis.
This species was discovered in SA by Alex Stolarski and I in November 2002 on Googs Track in the western EP Region. Remarkably, the two (female) individuals found were on the same host plant species as used by E. australis and only 11.6 and 14.8 km away, respectively, from where that was collected.
It is known in WA from a matching specimen in the collection of M. Powell, taken on the Hyden- Norseman road in 1986 (M. Hanlon, pers. com., Dec 2022).
Both individuals were collected by sweeping tussocks of Sandhill Sword-sedge (Lepidosperma hispidulum), which is considered likely to be its larval host also.
