Hello, is it possible to conclude group rosae / nigricornis here?

I base myself on criteria which seem visible to me, or which can be guessed from the photo despite the lack of definition: black pronotum including humerus, yellow legs, 2 pairs of dorso-central setae.

The third antennal section seems very little dark, but I understand that this is insufficient to exclude nigricornis.

Thank you

Luc

Nobody confirms? thanks in advance

Too few details visible to say which group of Chamaepsila...

---

Thanks for your answer

---

If necessary, I can show a more telling view of the pronotum (where I can count 2 pairs of dorsocentral setae) or a more telling view of the face

---

That being said it should indeed run to the pair of rosae and nigricornis (assuming the whole of the pleura is dark).

I tried to number what I see of the bristles, I hope I haven't misinterpreted. If this was the case, I thank you in advance for your indulgence!

Does this suggestion for numbering the bristles seem correct to you?
