Abida secale cadiensis Gittenberger, 1973 (pl. 6 figs D–L)

Abida secale cadiensis Gittenberger, 1973: 110 .

Type locality: Spain, Lérida, Martinet.

Holotype: National Museum of Natural History ( RMNH), Leiden 54782.

Distribution.—See fig. 2 .

Description (after Gittenberger 1973).—Shell cylindro-conical, with 7 3/4–8 1/2 weakly to moderately inflated whorls, sculpturedwith irregularly placed, weak axial striae, rather glossy. Body whorl obliquely flattened, not or only slightly narrowed, with a more or less distinct keel. Infrapalatalis accompanied by more or less prominent external indentation. Palatal side of the aperture slightly leaning forward (in lateral view). Umbilicus very narrowly open. Aperture not or hardly protruding. Shell height, 5.2–7.5 mm; width, 2.2–2.8 mm.

Apertural lip weakly thickened, continuous across the parietal side by a (very) strong callus. Angularis not connected with spiralis, ending approximately where a prominent parietalis begins. Subangularis obsolete, a minor knob attached to the angularis, or missing. Infraparietalis absent. Columellaris somewhat more prominent than infracolumellaris, both not reaching beyond the columella. Palatalis inferior and palatalis superior interrupted, reaching up to the edge of the aperture. Infrapalatalis short but prominent at the anterodorsal palatal center, not or only very weakly developed in the frontal part of the palatal folds. Suprapalatalis and occasionally a weak suturalis are present at the anterodorsal palatal center.

Genetic barcode.—GenBank accession numbers EU395374 – EU395377 , EU395383 – EU395384 .

Notes.— Abida s. cadiensis is clearly a high-altitude form, ‘derived’ from A. s. brongersmai, which looks very different at first sight. However, a series of intermediates is known from the northern side of the Sierra del Cadí, especially from the Comabona mtn (pl. 6 figs I–K).
