Tonicia lebruni (Rochebrune, 1884) Fig. 3D

Material examined.

117 spm (12 × 6 - 32 × 16 mm).

Synonymy.

See Kaas et al. (2006).

Remarks.

Frequently, it was considered a synonym for the species Tonicia calbucensis Plate, 1898, until Tonicia calbucensis was re-established as a valid species, based on six different characteristics between both species ( Schwabe et al. 2006, p. 15). Sirenko (2006) stated that this species incubates its eggs in the pallial cavity until juvenile, and consequently in this study, a sample from the winter season was found with juveniles in the pallial cavity.
