Anosycolus Fischer-Piete, Ch. P. Blanc, F. Blanc & F. Salvat 1993

Genus Anosycolus Fischer-Piete, Ch. P. Blanc, F. Blanc & F. Salvat, 1993 (Fig. 10A) Anosocolus Fischer-Piete, Ch. P. Blanc, F. Blanc & F. Salvat, 1993: 77. Tope species: Anosocolus anosocolus Fischer-Piete, Ch. P. Blanc, F. Blanc & F. Salvat, 1993 (by original designation). Remarks: Anosocolus is included in the Boucardicinae, owing to the presence of microtunnels on the last whorl of the type species. Boucardicus, in the present sense, is an extremely variable genus in terms of shell size, shell and aperture shape, and sculpture, and Anosocolus differs from some large, triangular Boucardicus species (e.g. Fig. 10B) only in minor characters, such as the keeled body whorl and closed umbilicus. Tis might suggest that Anosocolus and large-shelled Boucardicus are more closely related to each other than are large, triangular-shelled and small, ovoid Boucardicus species (e.g. Fig. 10D). Clearly, a genus-level revision of Boucardicus is needed in order to provide a phylogenetically meaningful subdivision of this mega-genus.
