Chrysallida hoeisaeteri sp.n. - Warén 1991:98

Chrysallida hoeisaeteri Warén - Høisaeter 2009

Type material: Holotype (2.00 mm) SMNH 4091

Type locality: Southwestern Norway, off Korsfjorden 60º08’N, 04º56’E, 270- 250 m.

Material seen: Norway – Nordland 2 spms; Troms, 8 shs.

Diagnosis: Shell: Strongly convex whorls with prosocline axial ribs and three spiral cords. Protoconch high with smooth surface, well defined transition from protoconch to teleoconch. Soft parts: Not known. Operculum: Not known.

Biology: Not known.

Distribution: Norway, known from a specimen from the shelf outside Korsfjorden (holotype). In my material three samples with respectively six, three and five somewhat worn shells might belong to this species. These are from the same three stations in the outer part of Andfjorden (Bleiksdjupet and the Steinavaer coral reef) as C. bjoernssoni is reported from above. (The two specimens from Nordland referred to above are questionable). Outside Norway only known from a few specimens from northern Iceland, and some shells from southeastern Iceland and eastern Greenland (Warén 1991).

Remarks: Belongs to a species complex together with C. eximia and C. bjoernssoni. Differs from C. eximia by fewer, stronger and more prosocline axial ribs, and from C. bjoernssoni by the likewise prosocline axial ribs, a more conical shape, and a protoconch without keel and well defined transition to teleoconch (Figure 24 right).
