Type locality: France , Basses-Pyrénées , Défilé d’Escot , right side of Vallée d’Aspe. Holotype : RMNH 54882 . Distribution.— France , Basses-Pyrénées, Vallée d’Aspe. Description (after Gittenberger 1973 ).—Shell moderately slender fusiform, recalling a Chondrina species in general shape, with 7¼–8 weakly to moderately inflated whorls, sculptured with regularly placed, weak axial ribs. Body whorl obliquely flattened, not or only slightly narrowed, with an indistinct keel. No apparent indentation behind apertural lip. The palatal side of the aperture slightly leaning forward (in lateral view). Umbilicus obscured by the last part of the body whorl. Shell height, 5.8–6.9 mm , width, 2.2–2.6 mm . Apertural lip moderately to strongly thickened. The parietal edges of the aperture are connected by a thin callus. Angularis connected with spiralis. Subangularis weak. Often with an infraparietalis. Columellar lamellae reaching clearly beyond the columella, without reaching the edge of the aperture. Infracolumellaris slightly less prominent than columellaris. A basalis is often present, which can be as prominent as the infracolumellaris. Infrapalatalis and palatalis inferior neither indented nor interrupted; in some specimens the palatalis superior is weakly indented. All palatal folds reaching the edge of the aperture. Suprapalatalis present at the anterodorsal palatal centre. Genetic barcode.—GenBank accession numbers EU395325 – EU395326 . Notes. —On the basis of shell characters this species was regarded as a subspecies of A. secale by Gittenberger (1973) . Molecular studies indicate that it should be considered the sister-species of A. vergniesiana , despite the fact that the shells of both species are very different ( Kokshoorn 2008: 93 ). Additional research should make clear whether this result can be confirmed.
