As far as I can see there is no supernumerary crossvein in cell dm and therefore it can't be Eloeophila sp.
I support paqui's suggestion. In fact I'm almost completely convinced it's Limnophila schranki.
The species name in Janet's link is in my opinion also doubtful. At least I don't see any clear evidence of an extra crossvein.

I'm all ears! Or eyes. ;) I'm desperately trying to understand where this supernumeray crossvein should be, not having experience in this I'm trying to learn. The best I can do is google to see if I can find it, what I found is difficult to understand.. this is a 2009 document.
The wing venation is rather uniform within the genus, yet variable in detail even within a species. Some species differ in the position of the supernumerary m-cu in respect to the extent of Rs or the tip of A2 and the comparative length of fork M1-M2 and its petiole (M1 2), but these differences may have little taxonomic value.

As usual, the structure of the male terminalia is essential for distinguishing the species, yet identification may be difficult due to the uniformity of some structures and variability of others.
does make this seem impossible from a single pic.
I found references with Eloeophila as being included under Limnophila in many places! That is, Limnophila (Eloeophila).
Wiki has a page of images, with both these species showing the wings, how accurate they are I don't know but most are from the Commanster site and I'm not sure how accurate they are.

Does anyone know of a (preferably internet) source for all Limoniidae?
