Ebert et al . (2008) examined two specimens and four egg cases of this species at SAM ; none had accession numbers. South African distribution : Known from three records west of Cape Town (WC) in very deep water ( Compagno & Ebert, 2007 ). Remarks : This species was previously referred to as Amblyraja robertsi , but recent molecular and morphological data confirm this species is the wide-ranging A. hyperborea that has a circumglobal distribution ( Last et al ., 2016a ). Two males, an adolescent and an adult, and four egg cases for this species were also trawled from 1,150 m off Cape Town ( Ebert et al ., 2008 ). Conservation status : LC (2016).
