Original diagnosis.
“Testa turrito-fusoidea, apice acuta. Anfractus longitudinaliter pluricostati, superne subcarinato-granulosi, transversim dense et parvillime sulcati. Apertura subovata. Columella intorta.
Cauda elongata
.”
[Shell turrito-fusoid, apex acute. Multicostate in axial direction, at upper side subcarinate-granulose, transversally densely and finely sulcate. Aperture subovate. Columella twisted. Siphonal canal elongate] (
Sacco 1891a: 59
).
Revised diagnosis.
“Narrow shape, quite long; pointed spire; whorls numerous, adorned with narrow, subnodular folds near the lower suture and in the middle of the height of each whorl; last whorl equals one quarter of the total width, attenuated at the base on which the axial folds extend. Aperture narrow, fusoid, terminated in front by a fairly long, narrow and twisted canal, not very deeply cut at the base; inner lip, thickened inside; columella inflected in a S, very elongated, unusually angular along the canal, covered with a thin and rather wide margin; very protruding hull, limiting the increase of the indentation on the neck of the channel
” (
Cossmann 1896: 57
, translated from French).
Discussion.
Fedosov
et al.
(2020)
placed two extant genera in
Pellifroniinae
:
Pellifronia
Terryn & Holford, 2008
and
Bathyterebra
Fedosov, Malcolm, Terryn, Gorson, Modica, Holford & Puillandre, 2020
. All extant species of this subfamily live in bathyal depths. Whilst the shells of
Pellifronia
have a typical terebrid outline,
Bathyterebra
differs by its fusiform shape due to the relatively high last whorl with convex outline (
Fedosov
et al
. 2020: 365
). In addition, it has a weakly defined subsutural band. In these features,
Bathyterebra
is strikingly similar to the monotypic Miocene genus
Fusoterebra
Sacco, 1891a
. Currently, three living species are placed in
Bathyterebra
:
Bathyterebra benthalis
(
Dall, 1889
)
,
B. coriolisi
(
Aubry, 1999
)
and
B. zhongshaensis
Malcolm, Terryn &
Fedosov,
2020
in
Fedosov
et al.
(2020)
. Especially,
B. benthalis
and
B. zhongshaensis
are reminiscent of
Fusoterebra terebrina
Bellardi & Michelotti, 1840
, the
type
species of
Fusoterebra
.
All living species differ from species of
Fusoterebra
in the inflated last whorl compared to the spire whorls. Moreover, the last whorl is not evenly convex in
Fusoterebra terebrina
but shouldered at the subsutral row of tubercles and slightly angled at the base.
