Conus (Lautoconus) damianakisi (Psarras, Merle & Koskeridou, 2022)
Shell description
Large shells (SL max.: 80.02 mm), with
smooth, conical spire whorls and spiral cords. Spire whorls straight to
slightly convex, with slightly concave outline in early spire whorls, straight
to slightly convex in later spire whorls, with smooth to slightly elevated
interactions of spire whorls, creating smooth, low conical to convex outline.
Multiple spiral cords on top of spire whorls, with three to four on early spire
whorls, up to ten on late spire whorls. Shoulder rounded. Maximum diameter
below shoulder. Suture, channelled, not straight. Subsutural flexure moderately
deep to shallow, moderately curved, strongly to moderately asymmetrical (Fig.
40H). Last spire whorl conical, straight. Aperture narrow, fasciole small,
slightly twisted. Spiral grooves near anterior part of last whorl. (1).
Description of colour pattern
The colour pattern on the spire whorls
consists of thin flammulae, frequently very closely related to united,
resulting in wide, fluorescent and comma shaped flammulae (Fig. 15, see apical
views). The colour pattern of the last whorls consists of two levels of
pigmentation. The first one consists of wide, dim-fluorescent spiral bands,
interrupted by non-fluorescent, thin spiral, continuous bands or lines. The
second level consists of very closely related, fluorescent dashes to continuous
lines. The dashes tend to be on an axial synchronization with other spiral
dashes-lines. The width of the spiral bands varies, as well as the number of
interruptions of the spiral lines. Also, the length of the dashes varies as
well, from almost dot-shaped dashes to continuous spiral lines (Fig. 16) (1).
Etymology
Named after Astrinos Damianakis, a private collector from Panassos
village, who helped us during the material collection (1).
Remarks
The characters of the spire whorls and the
colour pattern variation differentiate this species from the rest of the
studied material. The specimens are similar in morphology (Table 8) to Conus
pseudo-textilis Grateloup, var. pliocenica Erünal-Erentöz,
1958. The studied species differs from the variety of Erünal- Erentöz in
the slightly concave sutural ramps. This difference is crucial, because the
concave sutural ramps is shared between the specimens of Erünal-Erentöz and
members of Monteiroconus, but not the members of Lautoconus (1).
Stratigraphic range
Tortonian of Greece (Heraklion Basin, Crete) (1).
