Abida secale cadica ( Westerlund, 1902) (pl. 6 figs A–C)

Pupa ( Torquilla ) cadica Westerlund, 1902: 39.

Type locality: Spain, Lérida, Collado de Tancalaporta, Sierra del Cadí.

Lectotype: Naturhistoriska Museet Göteborg 2261.

Distribution.—See fig. 2 .

Description (after Gittenberger 1973). —Shell fusiform, relatively short, with 7 3/4–8 1/2 weakly inflated whorls, sculptured with regularly placed, weak axial ribs. Body whorl obliquely flattened, slightly narrowed, with a very distinct keel. Infrapalatalis accompanied by a very clear external indentation just behind apertural lip. Palatal side of the aperture slightly leaning forward (in lateral view). Umbilicus very narrowly open. Aperture more or less clearly protruding. Shell height, 6.1–7.5 mm; width, 2.2–2.5 mm.

Apertural lip strongly thickened, continuous across the parietal side, broadly reflexed and protruding up to c. 0.2 mm. Angularis relatively wide near the aperture but rapidly decreasing in prominence inside, reaching beyond the frontal end of the parietalis, hardly separated from the spiralis. Subangularis and infraparietalis missing. Columellaris somewhat more prominent than infracolumellaris, but both not reaching beyond columella. Infrapalatalis, palatalis inferior and palatalis superior interrupted, reaching up to the edge of the aperture. Suprapalatalis and a weak suturalis present at anterodorsal palatal center.

Genetic barcode.—GenBank accession number EU395368 .

Notes.—Additional material of this subspecies collected by the authors ( RMNH 104126 /15) fits the original description by Gittenberger (1973), which was based on 3 specimens only. However, the size range (shell height and width) has been updated. Abida s. cadica may be considered ‘derived’ from A. s. brauniopsis .
