Material. Anda 2 (1); Anda 3 (1); Anda 4 (1); Anda 6 (1); AndaDeVos (2); AndaClif3 (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.
