Diagnosis. Shell angular, rhomboidal in shape. High conical spire, sutures incised. Aperture oval. Teleoconch sculptured with spiral cords, densely packed with small scales. On the body whorl, higher and lower spiral cords set alternately. Six to seven axial ribs per whorl. Umbilical area moderately narrow, fasciole imbricated, umbilical furrow closed. Colouration operculum deep red to violet. Associated with alcyonacean and scleractinian host species. Also recorded from zoantharians and coralliomorpharians (Miller, 1981).
