Glyphis fuscocrenulata E.A. Smith, 1906

fuscocrenulata E.A. Smith, 1906: 56-57, Pl VIII, fig. 6 [ Glyphis , Port Shepstone and Umkomaas, Natal: 16 ×11.25× 6 mm].

Material examined.

Syntype. South Africa • KwaZulu-Natal, Umkomaas; H.C. Burnup leg.; T524; NMSA-MOL 001270; Fig. 3 (14.13 ×9.65× 5 mm).

Current status.

Diodora fuscocrenulata (E. A. Smith, 1906); Herbert (2015).

Remarks.

The shell ( NMSA-MOL 001270) from Umkomaas and two of three shells ( NHMUK: 1906.6.23.15-17) from Port Shepstone in the Natural History Museum (London, UK) were not explicitly mentioned in the original description. The sentence "However, the specimen described appears to be fairly mature" ( Smith 1906: 57) implies that the description was based on one shell, which makes it holotype by monotypy (ICZN 73.1.2.). However, Smith was aware that the shell from Umkomaas belongs to the same species, as indicated in the description: "Hab. - Port Shepstone and Umkomaas, Natal" ( Smith 1906: 57), which suggests that the shell from Umkomaas is part of the type series (see the Example for ICZN 72.4.1.1). We have not made changes in nomenclature and treat all four shells as syntypes, thereby not restricting possibilities in the next taxonomic revision.
