Dermatobranchus rodmani can be distinguished from other arminaceans by the yellowish-pink marginal band to the mantle and the oral veil with minute brown spots.There are one or two transverse brownish bands/patches on the pale tan mantle.
Let me quote Gosliner & Fahey (2011): "The ground colour of the notum, the oral veil, and the foot is pale pinkish white to tan. One or two transverse brown patches are present near the anterior and posterior thirds of the body. The notum and oral veil have a yellowish margin, which may contain fine punctations of brown. The rhinophores, including the base, lamellae, and apex, are brown with a few opaque white spots on their surface."
Dermatobranchus rodmani is Dermatobranchus sp. 16 in IPN at page 313:

Pretty similar are:
Dermatobranchus fasciatus, which lacks the 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 differs by rounded tubercles on the dorsal surface,
Dermatobranchus sp. 14 which differs by series of minute brownish spots on the longitudinal ridges.
