Diagnosis

Polyps remote from each other, arranged irregularly on the surface of the branch, in alcohol preserved material 5–10 mm high and 4 mm wide. Polyp body wall cylindrical in shape and with smooth surface. Sclerites are unordered in the tentacles, the body wall and the coenenchyme.

Polyp tentacles contain: (1) warty clubs, up to 0.28 mm long; (2) club-like spindles, up to 0.3 mm long; and (3) spindles up to 0.4 mm long. The polyp body wall contains (1) warty clubs, up to 0.28 mm long; (2) club-like spindles, up to 0.4 mm long; (3) capstans and ovals, up to 0.15 mm long; and (4) spindles up to 0.4 mm long. The outer layer of coenenchyme densely filled with capstans and ovals, up to 0.15 mm long, and may contain warty spindles up to 0.19 mm long.

Etymology

The specific epithet is for Simushir Island (Kurile Islands, Sea of Okhotsk), nearest to the locality where the holotype was found.
