Remarks

First reported from Nouméa ( New Caledonia) by Bruce (1967b) and subsequently also in New Caledonia from Nouméa, Île Ouen, Baie du Prony, Île des Pins, and Lagoon Nord Ouest by Bruce (1991b). Previously reported from Madagascar, from Baie d’Ambaro ( Bruce 1977c) and also from Mitsio Island, by Bruce (1978a). The specimen from Pracel Bank at the depth of 55 m represents a new bathymetric record for this species, previously known only to 30 m ( Bruce 1991b). Unfortunately this identification cannot be considered absolutely certain as the specimen lacks a rostrum.

Distribution

Type locality: Chumbe Island, Zanzibar. Also known from Egypt, Israel, Jordan, Kenya, Zanzibar, Mozambique, Comoro Islands, Madagascar, Seychelles, Japan, Indonesia, Australia (Western Australia, Queensland), Caroline Islands, New Caledonia, and Hawaii .
