I'm guessing this may be the female of M.praefica - same place as the male cf. praefica I posted yesterday?

5/8/2009; Glamorgan, S Wales, dune scrub.

Thanks

same fly, different view.

---

Looks very dexiine to me (thin body & long legs) - and I think I can see 4 pairs of scutellar bristles and a projecting mouth edge. Other than that I am a bit confused so I'll leave this to Theo :) Nice fly though - they have lots of interesting things in the South Wales dunes, I hear :)

Thanks Chris, we await Theo, then...

I'm not convinced of either,


First of all, it is a male (pulvilli !)
Secondly the wing venation is not very Dexiinae.

So my guess would be Leskiini, which can be very Dexiinae. I see reddish sidemarkings in the first pic on tergites.

Could it be Bithia spreta ?


Theo

This is all getting very interesting (I didn't realise venation could be used to tell the tribe - must look into this). Anyway, here's another shot, it may add something.

Tim

any more lateral shot would help, no matter how blurry, but I'm still with Bithia


Theo

---

Sorry that's the most lateral view I got.

Tim

Interesting - Bithia spreta is quite rare here and I got one a few days ago but it didn't look very like this photo. Mine was much greyer and had very noticeable dusted, orange side patches.

---

I agree it is very dark for Bithia spreta, maybe another BIthia but you don't have that many, do you ?

It can't be Eriothrix (like in prolixa), because of the bare eyes, the broader vertex and the lack of costal spine.

So I'm running out of options, other than Bithia.

Pity we can't see the setulae on veins


Theo

OK guys, my mistake,

I just noted the outward oriented orbital in the first pic:

Pelatachina tibialis.


The tibiae didn't seem reddish, that why I did not think of it sooner.

Well, fruitful errors and all that...thanks Theo.
