Taxonomic Remarks
Aplus scacchianus (R. A. Philippi, 1844) is the species most similar to the new taxon described herein. Both possess shells with rounded whorls and numerous but relatively weak primary spiral cords compared with the other members of the genus. A. scacchianus differs by its smaller size (~9–15 mm vs. ~14–22 mm), a blunt and white coloured with orange dots protoconch tinged with orange dots, sculptured with weak spiral ribs, and its pattern in the teleoconch consisting of a yellowish background with discontinuous black spiral lines across the secondary cords, accompanied by black and white granules at the intersections of the spiral and axial sculpture. In contrast, A. dissimilis n. sp. typically possesses a very slender protoconch and a teleoconch with a monochromatic background featuring a white spiral band. However, A. scacchianus exhibits a wide chromatic variability, with specimens ranging from having a whitish background to very dark colouration. In the latter case, they may closely resemble small, thick specimens of A. dissimilis. In such cases, the shape and sculpture of the protoconch, in combination with the sculpture of the teleoconch, leave no doubt as to the correct identification.
