Material examined

WALTERS SHOAL • 1 living specimen; summit area, south, stn WB05; 33°15.1S, 43°54.5′ E; depth 26–30 m; 1 May 2017; DNA tissue sample; MNHN-2013-67305 • 1 living specimen; summit area, north-west, stn WB09; 33°13.8S, 43°55.8′ E; depth 27–30 m; 4 May 2017; DNA tissue sample; MNHN-2013-67306 .

Distribution

A shallow-water species known from the south-eastern coast of South Africa and several islands in the south-eastern Atlantic. The present records from the summit area of Walters Shoal represent an eastern extension of the known range.

Remarks

Evidently a species prone to dispersal to isolated shallow-water localities by rafting on kelp holdfasts. Return eddies of the eastward flowing Agulhas Return Current may extend in the direction of Walters Shoal (Lutjeharms & Ansorge 2001), facilitating colonisation.
