Diagnostic characters . Subrounded shell; segmented internal umbonal-ventral ridge ending in a rounded condyle; hook-like denticle on the ventral part of the umbonal reflection; median shallow radial depression bordered backward by a strong radial rib; finely granulose commarginal ribs on the anterior half, abruptly curved downward at the anterior one-fourth. Prodissoconch: shell type ST-2A; length about 270 µm; roundish outline; convex profile; P-1 not visible (but smaller than 100 µm); P-2 with regular low commarginal cordlets throughout and fine radials on the abapical stages; transition to the nepioconch rather well marked. Occurrence . Box-corer samples BC66 (3 specimens), BC72 (10); cores BC05 (5), BC21 (1), BC51 (1), BC72 (3). Maximum length: about 5 mm. Distribution and habitat . The species is reported to be widespread in the Atlantic (Lofoten to the Azores) and Mediterranean, being a wood-boring eurybathic element distributed from intertidal to bathyal depths (Nordsieck 1969; Di Geronimo & Panetta 1973; Di Geronimo et al. 2001; Oliver et al. 2016). It was regarded as accidental in VP (bathyal mud) biocoenosis (Pérès & Picard 1964). Fossil record.
