The first record of the ammonite subfamily Stoliczkaiinae in and one of 12 species of the subfamily now recognized from northern KwaZulu-Natal dates from the work of Spath northern KwaZulu-Natal: (1921, p. 286), who recorded a fragment (SAM-PCZ19046, Neophlycticeras (Neophlycticeras) brottianum (d’Orbigny, formerly Spath’s no. 4939), from the south side of the 1841) Manuan Creek. The preservation is that of the Mzinene N. (Protissotia) itierianum (d’Orbigny, 1841) Formation on the Skoenberg, and although indeterminate to species level, the generic assignation is clear. In 1955, van Stoliczkaia (Stoliczkaia) clavigera Neumayr, 1875 Hoepen described an enigmatic ammonite from the north S. (Lamnayella) tetragona Neumayr, 1875 bank of the lower reaches of the Mzinene as Zuluscaphites S. (L.) crotaloides (Stoliczka, 1864) orycteropusi, and interpreted it as a scaphitid – a heteromorph ammonite of the family Scaphitidae. Wright (1957) placed S. (L.) sanctaecatherinae Wright & Kennedy, 1984 Zuluscaphites in the Scaphitdae with a query. It is, in fact a S.
