Abida secale brauniopsis Altimira, 1963 (pl. 5 figs A–G)

Abida secale brauniopsis Altimira, 1963: 19 .

Type locality: Spain, Lérida, Gosol, Sierra del Cadí.

Lectotype: National Museum of Natural History ( RMNH), Leiden 54780.

Distribution.—See fig. 2 .

Description (after Gittenberger 1973).—Shell slender, fusiform to cylindro-conical, with 8 3/4–9 3/4 weakly inflated whorls, sculpturedwith regularly placed, fine axial ribs. Body whorl obliquely flattened, narrowed, with a very distinct keel. Palatalis superior accompanied by a slight external indentation. Infrapalatalis with a prominent external indentation just behind apertural lip. Palatal side of aperture vertical (in lateral view). Umbilicus widely open. Shell height, 7.5–10.8 mm; width, 2.5–2.8 mm.

Aperture narrowed, with only slightly curved columellar and palatal sides and basally a sharp angle. Apertural lip strongly thickened, continuous across parietal side, broadly reflected and often protruding up to 1 mm. Angularis relatively high near the aperture but quickly decreasing in prominence, reaching beyond the front end of the parietalis, not or only weakly connected with the spiralis. Subangularis connected with angularis. Infraparietalis obsolete or lacking. Columellaris not reaching beyond the columella, clearly broader than the other lamellae at its frontal, abrupt ending. Infracolumellaris reaching further beyond the columella but never up to the apertural lip. Infrapalatalis, palatalis inferior and palatalis superior indented, reaching up to the edge of the aperture; some additional minor lamellae are occasionally present on the palatal apertural lip. At the anterodorsal palatal center a suturalis, a somewhat stronger, but equally long suprapalatalis and a shorter basalis are present.

Genetic barcode.—GenBank accession numbers EU395345 – EU395347 , EU395349 – EU395356 .

Notes.—In the Sierra del Cadí, south of the Comabona, populations of Abida secale are found that are intermediate between A. s. brauniopsis and A. s. brongersmai. In these populations the shells share the multitude of folds on the apertural lip with A. s. brongersmai, but the aperture is still narrowed, not roundish (pl. 5 figs C–E).
