- Seguenzia cf. keikoae Poppe, Tagaro & Dekker, 2006 (Figures 6–7) cf. 2006 Seguenzia keikoae nov. spec.—Poppe, Tagaro & Dekker: p. 27, pl. 5, fig. 3. cf. 2008 a Seguenzia keikoae —Poppe & Tagaro: p. 162, pl. 26, fig. 3. Material. Anda 2 (1); Anda 3 (1); Anda 4 (1); Anda 6 (1); AndaDeVos (2); AndaClif 3 (1); Roxas (6). Characterization. Seguenzia with numerous low, thin more or less regularly spaced sigmoid axial lirae; H 1.9 mm, W 1.7 mm; DN 0.12 mm; two strong spiral ribs on shoulder, five on base; columella denticulate; adult shell with closed umbilicus. Distribution. Apart from the studied material, Seguenzia keikoae Poppe, Tagaro & Dekker, 2006 has been reported from Bohol, off Pamilacan Island, Philippines, in a sample from between 196–216 m water depth. Remarks. The attribution to S. keikoae is uncertain despite the overall similar shell morphology because the adult specimens in our material have a closed umbilicus. Specimens shown by Poppe et al. (2006) have a slit-like umbilicus, but the latter specimens might be juveniles.
