Diagnostic characters
. Oval shell; rounded anterior side; long and truncate posterior rostrum; right valve hinge with a strong posterior lateral tooth; radial ridge from the beaks to the ventral angle of the rostrum; rather evenly spaced commarginal lamellae, vanishing on the umbonal area and over the rostrum. Prodissoconch: shell type ST- 2D; length about 130 µm; ellipsoidal outline; convex profile; P-1 surface finely granulated; P-1/P-2 boundary illdefined; rim-like P-2; transition to the nepioconch well marked.
Remarks
.
G.O. Sars (1878, p. 88)
erroneously considered the valid species
Neaera lamellosa
M. Sars
as conspecific with
Neaera jugosa
S. Wood. Actually
,
Cuspidaria jugosa
(Wood S.V., 1857)
, although subsequently put in synonymy of
C. lamellosa
by some authors (e.g.
Nordsieck 1969
), appears to be a different species, as Wood (1857: p. 272) described it as possessing “eight to ten rounded ridges, with depressions or sulci between them of about the same breadth”.
Occurrence
. Box-corer samples BC05 (2 specimens), BC66 (1), BC72 (6); core BC72 (2). Maximum length:
3.5 mm
.
Distribution and habitat
. The species is found at outer shelf depths in
Norway
waters, and at deeper settings (down to
1100 m
) along both the Atlantic margins; it is an infaunal burrower inhabiting soft bottoms (Dall 1889[b];
Thomsen & Vorren 1986
;
Buhl-Mortensen & Høisaeter 1993
;

et al.
