Oval-trigonal shell; rather pointed beaks; short, rounded posterior rostrum; hinge with a very small cardinal tooth in each valve; single thin radial ridge from the beaks to the postero-ventral margin; shallow radial depression posterior to the ridge, corresponding to an internal strong fold. Prodissoconch: shell type ST-2D; length about 130 µm; slightly inequilateral (longer anteriorly), ellipsoidal outline; convex profile; P-1 surface with arcuate wrinkles in the cicatrix area; P-2 almost absent; transition to the nepioconch rather well marked. Occurrence . Box-corer samples BC71 (3 specimens), BC72 (26); core BC72 (2). Maximum length: 7 mm. Distribution and habitat . The species is distributed from northern Norway to Morocco and the Mediterranean, in the 460–1350 m depth interval (Nordsieck 1969; Buhl-Mortensen & Høisaeter 1993; Poppe & Goto 1993; Oliver et al. 2016).
