Ringicula View in CoL spec 4

( Figure 34 View FIGURE 34 – 40. 34 )

Material. Roxas (3) RGM 961.850.

Characterization. Shell small, high-spired; H 2.75 mm, W 1.52 mm; protoconch slightly elevated, 1.2 whorl, DP 0.23 mm; nucleus small, DN 0.12 mm; teleoconch with distinct subsutural ridge and groove; additional sculpture of 12 distinct spiral grooves on the body whorl; aperture damaged in all specimens; parietal callus with lamella; columella with two folds.

Remarks. These specimens are difficult to assign to a species, because of their broken apertures. Their spires are more elevated than that of any of the other Ringicula species present in the studied material. They might belong to Ringicula doliaris Gould, 1860 , because some specimens attributed to this species have a similarly elevated spire, with similar sculpture, but these specimens attain a larger size of at least 4 mm.
