Hydrellia

Hi,

Can anyone help with this Hydrellia I collected from a mountain in Wales in July? Of the many specimens collected that day all but this were H. maura.

Photos of the dissected genitalia are below. Apologies for the state of the preparation.

I observed the following features:
- Palps yellow
- Antennae all dark
- front coxae fully dusted
- 1 strong PS-DC
- 5 pairs of facial bristles   

However, the aedeagus doesn't seem to fit with any of the possibilities with  this set of characters in Martin Drake's test key.

Thanks for any help.

Sam
