Treatment

christiaensi Kilburn, 1978: 448, Plate 9c-e, 10 [ Puncturella (Vacerrena) , off Sordwana [sic] Bay, Zululand, 50 m, in shell grit (C.S.I.R. Department of Water Research): ~1.9 ×n/d× 1.5 mm, basal length 1.65 mm].

Material examined.

Holotype. South Africa • KwaZulu-Natal, off Sodwana Bay, depth 50 m, C.S.I.R. Water Res; shell grit; T2204; NMSA-MOL 0B230; Fig. 11 View Figure 11 (1.92 ×1.45× 1.41 mm; larger diameter (height) of aperture ("basal length") is 1.52 mm).

Paratypes. South Africa • 3 of 5; same data as holotype; T2205; NMSA-MOL 0A5084.

South Africa • 2; KwaZulu-Natal, off Kosi Bay, depth 50 m; C.S.I.R. Water Res; in shell drift; T2206; NMSA-MOL 0A5937.

Current status.

Vacerrena nana (H. Adams, 1872); Herbert (2015).

Remarks.

The shell of the holotype was damaged after the photos for the original description were made. The damage was first discovered in March 2012 by the first author and the part that was broken off was not located. Another set of dimensions (1.6 × 1.5 mm) is given in the figure captions for the plate 9(c-e) in the original description. We were unable to locate two out of five paratypes (T2205/ NMSA 0A5084). Genus Vacerrena is probably related to Cornisepta (Fig. 12 View Figure 12 ) and Profundisepta (Fig. 13 View Figure 13 ) but is not transferred here to Zeidorinae because it is not a taxonomic revision and there is no reference that can be cited to indicate that it should be in Zeidorinae .
