( Figures 61–63 )

2006 Minolia tabakotanii nov. spec.—Poppe et al.: p. 133, pl. 68, fig. 1. 2008d Minolia tabakotanii —Poppe & Tagaro: p. 224, pl. 57, fig. 2.

Material. Anda 1 (12); Anda 2 (14); Anda 3 (7); Anda 4 (26); Anda 5 (3); Anda 6 (2); AndaDeVos (4); AndaClif1 (3).

Characterization. Small turbiniform shell with rounded whorls, H 2.1 mm, W 1.8 mm); P smooth, globular, DN 0.10–0.11; P/T boundary at 1.2 whorls marked by indistinct rib; T reticulate ornamentation with axial lamellae and microscopic granules in interspaces; aperture circular; narrow umbilicus.

Distribution. Apart from the studied material, known only from the type locality offshore Mactan Island, Philippines from 200 m depth ( Poppe et al. 2006; Poppe & Tagaro 2008d).

Remarks. This species is assigned to Zetela on the basis of the similarity of its sculpture to that of the type species Z. textilis ( Murdoch & Suter, 1906) . It differs from that species by having a much smaller umbilicus and a more continuous peristome.
