Hiatavolva rugosa Cate & Azuma in Cate, 1973
Rugose ovulid

This species is found on the steep seaward reef slopes. They are similar to Aclyvolva lanceolata and A. sp., but the mantle papillae resemble the branching polyps of the gorgonian they live upon. Both the polyps and papillae are retracted in these photos, but they can be extended to look like small whitish flowers. Like A. lanceolata, this species lives on red whip-like gorgonians in the genus Ellisella.

A 14.1mm specimen is below.
