Rainbow dung beetle, Phanaeus vindex? - Phanaeus vindex

Rainbow dung beetle, Phanaeus vindex? - Phanaeus vindex
Billings, MT, Yellowstone County, Montana, USA
June 2, 2018
Finding live rainbow dung beetles in the wild in MT has been my "white whale" quest for some time. I knew they were here in MT but hadn't yet seen one in the wild. Unfortunately, this specimen, along with a couple of others, were dead, floating in a stock tank, when I found them. So the quest continues. I'm guessing Phanaeus vindex but would love confirmation as well as some help regarding sex. Is this beetle's horn considered "very short" as in females or just "short" as in minor males?

Thank you
Junsuk for your quick reply! I appreciate your help. Just out of curiosity, how big is the horn of a minor male? Is it similar to the female's or does it actually look more like the full-size male horn?
