nice addition!

Moved from Aphodiini.

Tried keying further in Gordon & Skelley 2007. Having tried quite a few different options in the key, the best match seemed to be Melinopterus prodromus - almost all characters in the description of this genus and species matched my specimen, with the notable and problematic exception that my specimen has definitely fimbriate pronotal margins, albeit shortly and sparsely so. The pronotum of this genus is described as "not laterally fimbriate." Nevertheless, other characters seemed to match very well, including the clypeus flattened and smooth, without ridges, with the anterior margin barely emarginate; pronotum black except for yellow lateral margins [and apical margin in my specimen], with coarse and fine punctures, the coarse punctures not present anteromedially, and with a complete basal line; elytra tan, pubescent especially apically, and fimbriate along the entire lateral margins, with some long setae near the humerus; venter dark, with somewhat long hairs; and apices of meso- and metatibiae fringed with unequal spinules. I also considered Phaeaphodius rectus for this specimen, but ruled it out because the description for clypeal sculpture did not match, nor did the pronotal sculpture match, nor was the basal segment of the metatarsus of this specimen as long as segments 2-4 combined [it was as long as 2-3 combined].
