Material examined.

40 spm (9 × 5 - 26 × 13 mm).

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).
