Distribution in Sri Lanka. Eastern coast of Sri Lanka.

Recorded depth range in Sri Lanka. 51 m (Anderson 1894).

Remarks. This species differs from other diadematoids found in Sri Lanka by having a very low test, conspicuously elongated, narrow genital plates, and spines in which the shaft is partially filled with a loose stereom meshwork.

Sarasin & Sarasin (1887), Döderlein (1888), and Anderson (1894) recorded this species from Trincomalee. One denuded specimen is housed at the Department of Aquaculture and Fisheries of the Wayamba University of Sri Lanka. This specimen was collected from off Trincomalee, but its depth is unknown.
