Dendropoma psarocephala Hadfield and Kay, 1972. Shell: small (maximum tube diameter 2.5 mm); tube deposited in a vertical helical coil but often conforming to the substrate. Aperture circular, flush with the substrate. With irregular axial riblets which may be developed as laminae on the inner surface of the shell. Dark purple. Operculum: convex, thick, ranging from buttonlike to domed in shape; composed of concentric layers of dark red, chitinous material; pedal surface rimmed by a dark glossy red annulus edged with white and with a white mamilla. Animal: head and foot black with superficial white spots; rolled edge of mantle collar with tiny black pigment spots. Mantle margin entire in both sexes.
These small vermetids are solitary but settle within one to two millimeters of each other on coralline-algal encrusted coral on fringing and patch reefs at Waikiki and in Kaneohe Bay, Oahu.
D. psarocephala was described from the Hawaiian Islands.
