DIAGNOSIS. — Protoconch multispiral. Teleoconch squat to moderately elongate, obconic shells with broad and rounded shoulders. Spire whorls low to very low, smooth, convex. Subsutural flexure very shallow in small species - deep in larger species, moderately curved and moderately asymmetrical. Colour pattern consists mainly of spirally arranged spots and dashes in continuous spiral rows (Diagnosis followingTucker & Tenorio (2009) and
Harzhauser & Landau (2016)

REMARKS
Puillandre
et al.
(2014)
considered
Kalloconus
at subgenus level and found a monophyletic group. Today
Kalloconus
is restricted to the tropical East Atlantic (West Africa), but its fossil record demonstrates that it also had a European distribution during the Miocene in the Proto- Mediterranean and Paratethys.
Conus
(
Kalloconus
)
can be distinguished from
Conus
(
Monteiroconus
)
, mainly by the lack of spiral cords on the whorls and by its straight, lightly concave whorls.
