Prionocera turcica, or just Prionocera species?

I have found something like this before, but never achieved a definite ID.
This one has a visible wedge-shaped dark stripe on the head - previous ones were a bit questionable in this respect. But I can't remember what are the key features. It looks good compared with images on Craneflies of the World.

The first photo is rubbish, but then I was balanced on the edge of a swampy pond. It just gives the jizz.

Re: Prionocera turcica, or just Prionocera species?

As usual, the male genitalia are the best diagnostic features for this genus.  I would put it down as a female Prionocera sp, but it is most likely to be P. turcica.  The rostrum is said to be all black in P. pubescens (a hairy fly) and with yellow present in P. turcica.  The end photo shows a rostrum which is black dorsally, but yellow ventrally.  I'm not sure about P. subserricornis.

Thanks John.
I do seem to have come across several likely candidates recently for this species, but I never actually recognise them at the time. I leave the identification bit until later.  That makes it awkward.
And they have all been female anyway.
Some things are not meant to be!
