Dermatobranchus fasciatus can be distinguished from other arminaceans by two transverse brownish bands/patches and many small black/brown spots on the pale tan mantle. Let me quote Gosliner & Fahey (2011): "The bands of dark colour divide the dorsum into approximate thirds. The dorsal ridges are the same white as the ground colour and the depressions between the ridges are grey. The rhinophore stalk is white with some random dark spots and the club is dark brown to black with opaque white spots. The oral veil is opaque white with dark spots and a pink margin." It feeds on soft-corals.
Dermatobranchus fasciatus is as Dermatobranchus sp. 6 in IPN at page 310

Pretty similar are:
Dermatobranchus rodmani, which differs by a yellowish-pink marginal band with brown dots,
Dermatobranchus semilunus, which differs by the U-shaped brownish patch at the anterior third of the notum, and
Dermatobranchus tuberculatus, which lacks the prominent longitudinal ridges, and differs by rounded tubercles on the dorsal surface,
Dermatobranchus sp. 14 which differs by series of minute brownish spots on the longitudinal ridges.
