Could this be Dasyhelea bilineata? Caught indoors in Feb (Vienna).

I can not tell beyond genus Dasyhelea. D. bilineata has long third palpomere (visible here), antenna ratio very close to 1.0 (possibly larger here), legs usually with dark bands, scutellum with 10-12 bristles (possibly fewer here), wing length 1.6-1.8 mm (no scale bar here). |

Here some more aspects - the antennal ratio is now hard to show, so I left it out. Legs rather dark with yellow rings  Tip of last flagellomere with pin-like tip  Around 12 scutellar bristles  Wing length: obviously need a finer scale, maybe around1.8mm  Wing seems to have two radial cells (or is this open?)  So, I feel good with Subgenus Dasyhelea, and in particular D. bilineata, but the wing confuses me... Any more comments highly appreciated Edited by Carnifex on 25-02-2021 22:45 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.
