South Africa voucher material: ANSP 53046.
South Africa distribution: Known from a single specimen picked up on a beach at Durban (Fowler, 1934).
Remarks: The holotype was picked up on a beach near Vetches Pier, Durban, on 4 January 1923. The 12.6 cm TL female specimen was collected by H.W. Bell-Marley who sent it to H.W. Fowler who originally mistook it for Heteroscymnus longus Tanaka, 1912; a species referable to the genus Somniosus. Fowler (1934) later revised his original identification and described it as a new genus and species. The species appears to be wide-ranging in the Southern Hemisphere with the only six known specimens occurring in three widely dispersed locations in the southwestern Indian Ocean, southeastern Atlantic Ocean, and southeastern Pacific Ocean (Ebert, 2015).
Conservation status: LC (2019).
