Haliotis unilateralis Lamarck, 1822

Haliotis unilateralis Lamarck, 1822a: 217 , no. 11. Geiger, 1996: 341, figs 2, 4. Geiger & Poppe, 2000: 91, pl. 19. Pickery & Verbinnen, 2004: 21, figs 22–26. Owen, 2007a. Geiger & Owen, 2012: 136, pl. 72 (additional synonyms and references). Type loc.: ‘les mers de Timor et de la Nouvelle-Hollande’ [the seas of Timor and of Australia], evidently erroneous; neotype in MHNG (18020) designated by Geiger (1996: 345).

Haliotis barbouri Foster, 1946: 40 , pl. 23. Owen, 2006a: 183, 184, pl. 4. Deuss et al., 2013: 131, fig. m. Type loc.: ‘Praia de Copacabana’, Brazil [erroneous]; holotype in MCZ (152469).

Haliotis (Sulculus) unilateralis — Yaron, 1983b: 489.

Haliotis ovina (non Gmelin, 1791)— Steyn & Lussi, 2005: 10, no. 4.

Distribution. Red Sea and the western Indian Ocean ( Geiger & Owen 2012), south to central Zululand (Leadsman Shoal); local material 7–105 m, mostly <50 m (living 7–50 m).

Notes. Considerable confusion has surrounded the identity of small haliotids (max. dimension <40 mm) occurring in northern KwaZulu-Natal and southern Mozambique, but Owen (2007a) has provided good evidence to show that the material is referable to H. unilateralis . Haliotis ovina Gmelin, 1791 , under which name Steyn & Lussi (2005) recorded these specimens, is larger, more robust and distributed primarily in the central Indo-West Pacific ( Geiger & Owen 2012).
