Genus
Athleta
Conrad, 1853
Type
species.
Voluta rarispina
Lamarck, 1811
(Neogene, Europe) by subsequent designation (
Dall 1890
).
Comments.
1) Many authors consider the gender of
Athleta
to be feminine, but it is masculine. 2)
Darragh (1971)
synonymised a number of genera with
Athleta
,
among which were
Volutospina
Newton, 1906
,
Volutopupa
Dall, 1890
and
Volutocorbis
Dall, 1890
and recognised only two subgenera,
Athleta
(s.s.)
and
A. (Ternivoluta)
Martens, 1897. However, the difference between the two subgenera used by
Darragh (1971)
is solely based on the multispiral versus paucispiral protoconch, a developmental difference not now considered to be of taxonomic significance, as in the
Harpidae (
Merle & Pacaud 2003
)
or the
Muricidae (
Merle
et al.
2011
)
for example. The aim of this work is not to revise the genus
Athleta
and a cladistic analysis would be necessary for this revision. For instance, we prefer to continue to use provisionally
Volutopupa
(see
Pacaud & Pons 2013
),
Volutocorbis
and
Volutospina
as subgenera, because they are useful to characterize different Paleogene morphotypes.
