Not sure about Muscidae.

Thank you very much!

Trying to key this myself (as exercise), it was a bit of a puzzle. I at least added better pictures of the hind tibia and the scutellum. My key route:

Keyed to either subfamily Mydaeinae or tribe Phaoniini (cerci size needed). Keying Mydaeinae I would get to the genus of Hebecnema, which would not fit the chaetotaxy of the tibia (mid tibia should only have 2 pd, and 1-2 av). Keying Phaoniini, would match Helina genus.


I have tried many key routes (cubital node bare or not bare, with or without ventral pale hairs on the scutullem), but none of the species seem to match. Especially with the all dark legs:

[Hypopleuron beneath spiracle seemingly bare, key with hairs also does not keys to a valid species], radio cubital node seemingly bare (split just to be sure):

cubital node bare: hind tibia without clear pd, no strong presutural acrostichal bristles, 4 dc, sterno 2+2, [legs black, pre-alar seems to be missing, no strong av on hind femur -> not H. subvittata] -> stuck with the dark legs

cubital node not bare: scuttelum seemingly without erect pale hairs towards the tip, [frons around width of an eye, scuttelum with hairs on the lateral margins, pre-alar broken?] -> keys to H. ciliatocosta, but does not fit leg colour

[cubital node not bare + scuttelum pale hairs]: front tibia without a strong posterior setae, dark legs -> not H. cilipes or H. cinerella

I seemed to have missed the sternopleural coupled, which notices a weak seta beneath the stronger front seta. Which is relevant if the legs are black and antennae plumose

Sternopleurals 1:2 (sometimes with a second weak seta below the front seta, but then arista long plumose and legs black).


Which would match in this case, and would key out to "Helina deleta". The yellowish colored wing at the base, and No further abdomen spots, also matches this species.

Not one registered in NL yet, so still unlikely.

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
