Moved from Aphodiini.

 
Thanks for the ID, MJ.
In keeping with the learning/teaching function of this site could you offer some anatomical distinctions that went into your determination?

Moved
Moved from Aphodius.

Sure
Overall, I'd say Ataenius sp. - all black, pronotum with flared edges apically, hind tibia with first tarsomere very long, but I think I see distinct transverse carina on the hind tibia which says Aphodius sp. - will have to look into further. This should be easy to nail down - I'm guessing the fauna in NH is limited.

Do you have this speciman? - if so check the pygidium (pull down to expose the whole); evenly concave (Aphodius) or longitudinally divided (Ataenius).

 
Fauna limited
For certain. Only 19 Aphodius and four Ataenius species. I'll make a trip to my attic and see if I have any vouchers in my jumble of dried beetle corpses from that period. If so, I reckon I should soak the specimen before I try any pygidium deflections.

 
Yes,
it appears that I do have these beetles, but I'll need to re-photograph them and compare images to be sure.
