Dark Demon

From Diablo Wiki

Dark Demons are demons. These odd, half-skeletal creatures are summoned from raw, red manhole-like openings in the ground by Dark Cultists.

They are quadrupedal, and look a bit like a dog crossed with a crocodile, then turned inside out. They are quick of foot, but appear to possess only melee attacks.
