Mystery Cranefly

I've another problem specimen with odd wing venation.  win length is only 4.8mm. I've really no idea with this  as it is a female so I can't even compare genitalia pics.

Re: Mystery Cranefly

Hi Steve. This is a challenge !!!  The bit of wing venation I can see looks like Limoniinae.  The process of metamorphosis has gone wrong and so in place of the adult genitalia are what seem to be the remnants of the larval structures.  This could possibly be Antocha vitripennis, the adults of which have very large 'squared' anal angles.  This should be clearer when you view the specimen.  The colour of this species is very variable.  It is fairly local, by streams.
