Tipula possibly lateralis

I am reliably informed that -

"It could be Tipula (Yamatotipula) lateralis or T. (Acutipula) vittata; both can have the abdomen of that colour, with sublateral dark stripes.  Of course, at whole animal view, these are very different in size, wing pattern and top of thorax stripe pattern.  Since the abdomen dark stripes are not intensely dark, I suspect it is lateralis but that is not a firm det.  The inner claspers are different but since the key features are obscured (as usual) the key does without that detail."

(from the genitalia drawings I would go for lateralis; but I am usually wrong)

Ignore this message (I cannot delete it). as I got the picture to upload

I found I have one voucher specimen of Tipula vittata and photographed its thorax to compare with a specimen of Tipula lateralis (I rechecked I got the pictures the right way around).

Finally got the upload to work, have to click on 'Image' to continue
