discussion

Remarks: Smith (1957 a) described a new genus (Neotriakis) for this species, but subsequent reviews determined it to be in the genus Eridacnis (Compagno, 1970, 1984 b, 1988 a; Bass et al., 1975 b). The species appears to be relatively common in KZN waters, but also occurs off Mozambique and Tanzania. Conservation status: LC (2019).
