Consideraciones nomenclaturales sobre las especies del género Allognathus (Gastropoda: Pulmonata: Helicidae) y estudio anatómico de Allognathus hispanicus tanitianus

A nomenclatural revision of the species of the genus Allognathus Pilsbry, 1888, endemic of the Balearic Islands (Spain) is conducted in the present work. Particular mention is given to Allognathus (Allognathus) grateloupi, A. (Iberellus) hispanicus and A. (I.) hispanicus campanyonii. Furthermore, we include a redescription of the reproductive apparatus of A. (I.) hispanicus tanitianus (Forés & Vilella, 1993) as the original description does not represent accurately, in our opinion, the morphology of the reproductive apparatus.
