- Calliobasis lapulapui Poppe, Tagaro & Dekker, 2006 (Figures 18–19) 2006 Calliobasis lapulapui nov. spec.—Poppe et al.: p. 21, pl. 1, fig. 2. 2008 a Calliobasis lapulapui —Poppe & Tagaro: p. 160, pl. 25, fig. 1. Material. Anda 1 (72); Anda 2 (81); Anda 3 (44); Anda 4 (83); Anda 5 (1); Anda 6 (2); AndaDeVos (3); Roxas (1); Tiep 3 (3); Tiep 5 (5). Characterization. Conical shell with regularly-spaced, well-defined erect sigmoid axial ribs, H 2.5 mm, W 2.6 mm; P globular, 1.1 whorls, DN 0.10 mm; one or two spiral ribs on lower T whorls; body whorl with strong keel; base with nine spiral ribs; plane of aperture tilted downwards; outer lip with strong upper and lower retractions. Distribution. Apart from the studied material, Calliobasis lapulapui has been reported from the Dipolog Bay, Mindanao Island, Philippines, 172–175 m depth (Poppe et al. 2006). Remarks. The specimen shown in Poppe et al. (2006) does not have the elaborate outer lip organisation, but is likely not fully grown. It is smaller than the fossil material studied here (H 2.2 mm versus H 2.53 mm). The shape of the shell and the ornamentation are the same as in the fossils studied here. Subfamily Asthelysinae Marshall, 1991
