Synonymy.
See
Kaas et al. (2006)
.
Remarks.
Sirenko (2006)
did not include this species within the list of Magellanic
Polyplacophora
. However,
Schwabe et al. (2006)
named it as
Tonicia chilensis
for all individuals that presented the following characteristics: well-marked micro-granulations in all of the valves, granules that are marked towards the margins of the valves, characteristics that other species of the genus did not present, except
Tonicia lebruni
. Our specimens did present granules but disposed in an irregular form, and
Tonicia calbucencis
sometimes can present granules along the entirety of the margins (
Schwabe et al. 2006
).
