Helina

Submitted by sifolinia on Mon, 21/06/2021 - 17:31

I've got a female Helina that's keying out confidently to the fratercula/consimilis/vicina couplets in the Fonseca RES key to Muscidae. It's clearly not fratercula, as the hind tibia have no posterodorsals (or scars) and it has only one anteroventral. However, the mid femur have three (slightly postero)ventral near the base, which would seem to rule out consimilis and vicina. I'm therefore at a bit of a loss.

I'm aware that there are several Helina spp. added since Fonseca, but I don't have details. Could this species be one of them? Or something new?

I'd value any information. Please let me know if photos will help, as I can sort them out.

Mike
