Dermatobranchus dendronephthyphagus is a species of sea slug, a nudibranch, a marine gastropod mollusc in the family Arminidae.[1]
This species occurs in the Indo-Pacific region. It was described from Okinawa, Ryukyu Islands, Japan. A specimen from Eastern Australia identified as Dermatobranchus nigropunctatus is probably a misidentification of this species.[2]
