Calliotropis limbifera ( Schepman, 1908)

( Figures 33–34 )

1908 Solariellopsis limbifera nov. spec.—Schepman: p. 54–55, pl. IV, fig. 3. 1979 Calliotropis limbifera — Marshall: p. 526.

2007 Calliotropis limbifera —Vilvens: p. 50, figs 172–175.

Material. AndaDeVos (1 adult, damaged; 1 juvenile, damaged); AndaClif3 (1 juvenile, damaged).

Characterization. Shell broadly conical, keeled, H 3.1 mm, W 5.0 mm; P large, bulbous, weakly granulate, 1.1 whorls, DN 0.25 mm; P/T boundary weak rib; T microsculpture of discontinuous axial threads; reticulate ornamentation on first 2.5 T whorls; ornamentation changes to rows of knobs, rows of scales with axial lirae in between and a keel ornamented with axial ribs.

Distribution. Apart from the studied material the species is known from the Sulu Archipelago, Philippines, 522 m depth ( Schepman 1908) and the south-western Pacific, 315–415 m depth ( Vilvens 2007).
