Several other genera of tachinids are constantly being lumped with Archytas. In the Nearctic, these include Juriniopsis, Tachina, Epalpus, Peleteria/Deopalpus, and Pararchytas.

Juriniopsis has a more bristly abdomen (several pairs of median marginal bristles on tergites 3 and 4, Archytas has just one, so the abdomen appears to lack bristles).
Peleteria/Deopalpus have two distinct, black bristles originating near the bottom of the eye on the face, next to the vibrissa. In the Nearctic, they tend to be more grayish in color, with some species, especially in the west, with an extensively orange abdomen at least in Peleteria. None of the other genera in this comment have these bristles. Peleteria have palpi present (but thin and hard to see) while Deopalpus have the palpi entirely absent.
Tachina has a differently shaped antennae than Archytas. The last antennal segment in Archytas is kidney-shaped while in Tachina is short and round, often shorter than the second segment of the antennae. Tachina at least in North America tend to have the back of the head with yellow hairs but the rest of the body black. Archytas rarely if ever share this look.
Pararchytas is a less common (usually northern) genus that appears as a hybrid of Juriniopsis and Archytas in abdominal bristling. Pararchytas also has the wings yellowish with dark margins along the veins. The abdomen of Pararchytas differs from Juriniopsis by the presence of median discal bristles on tergite 3 and probably 4 (bristles originating on the center of the segment, not near the margins) and differs from Archytas by still having more median marginal bristles.
Epalpus has the abdomen reddish or dark with a light patch at the end. Possesses reduced palpi or palpi entirely absent.

This seems to be a comment on the difficulty of the identification of this group, not an error in the taxon that needs curation. Is there anything here that needs to be fixed by a curator?

@cmcheatle Yes, this is the case here. Should add a link to the forum post next time.
