DIAGNOSIS. — Biconic shell.Scalariform spire,angular,carinate shoulder, which often bears tubercles, but no spiral sculpture (

Based on our material, we show that the subsutural flexures are variable from shallow (e.g.,
Conilithes brezinae
(
Hoernes & Auinger, 1879
))
to deep (e.g., mean SSFD of
Conilithes herodus
n. sp.
). In addition, early teleoconchs whorls can be devoid of beads (e.g.,
Conilithes striatulus
(
Brocchi, 1814
))
and rarely species display beads on their last whorls (e.g.,
Conilithes
sp.
). The stratigraphical range of the genus is Eocene to Pliocene of Europe (Proto-Mediterranean and Paratethys) and North America (
Harzhauser & Landau 2016
).
