Yes, I'd go for a tachinid too - I have seen similar in samples but heaven knows what they are :D There seems to be a complex of species around that colour pattern.

As a guide it is clearly a calyptrate fly (house-fly type), the median vein is bent (typical of tachinids but not conclusive for any family), hypopleurals strong and strong bristles present ... so favours tachinids. It doesn't look like an anthomyid or rhinophorid or calliphorid or sarcophagid ... so again it must be a tachinid! :D

Attached I point out the place of HYPOPLEURAL bristles = Meral bristles, and the M vein with a strong bent to the wing margin.

I must add that MERAL bristles can EXIST in Muscids! But they are not well developed. Exceptions belonging to this are Eginia which it has strong meral bristles (not sure if there is in Peru...), and probably there will be much more in Peru. ;)

The presence of a strong and convex subscutellum points us to Tachinidae. Not visible in this photo.

When there are some bristles on meron for Muscidae (Eginiini indeed), they are well less developped than here and never arranged in a row like this. Others Muscidae can have some miscroscopic hairs on meron.
