Synaptocochlea concinna (Gould, 1845) —new record Stomatella concinna Gould, 1845: 26. Viader, 1937: 56. Johnson, 1964: 58, pl. 21, fig. 7. Type loc.: Sandwich Islands [Hawaii]; holotype in MCZ (169090), figured by Johnson (1964). Synaptocochlea concinna — Ladd, 1966: 41, pl. 5, figs 20–23. Cernohorsky, 1978: 36, pl. 9, fig. 10. Kay, 1979: 53, fig. 14 H, I. Fukuda, 1993: 26, pl. 7, fig. 83. Wilson, 1993: 69. Herbert, 1996: 417. Zuschin et al., 2009: 97, pl. 7, fig. 3. Gena concinna — Jay, 2014. Distribution. Indo-West Pacific to KwaZulu-Natal south coast (Aliwal Shoal); local material 5–50 m (living 15 m). Notes. Whether South African material is genuinely conspecific with the tropical S. concinna requires confirmation. Abbott (1958) suggested that concinna was no more than a subspecies of the Caribbean S. picta (d’Orbigny, 1847).
