Australian Elasmus

Can anyone suggest a family for these wasps. Pictures sent to me from a friend. My guess is Eupelmidae? The following link is from his website, David Rentz.

The wasps hatched from the cocoons along with some moths.

They look like our european Elasmus sp (Eulophidae). You had a female there and here is a male.
Among other features, the hind tibia with short bristles forming distinct diamond-shaped structure is caracteristic.
As far as I know, Elasmus in the only henus in Elasmini. But???

I think Bilule is correct about Elasmus being the only genus in the group (once considered a family, then a subfamily of Eulophidae, and now possibly a tribe within the Eulophinae). They are known to be Lepidoptera parasitoids. The other distinctive characters are GREATLY enlarged hind coxae, long narrow wings (anterior and posterior edges almost parallel) with a very long marginal vein, and the scutellum with a laminar projection.
