Abida secale lilietensis ( Bofill, 1886) (pl. 3 figs A–H)

Pupa lilietensis Bofill, 1886: 155. Type locality:, Spain, Barcelona , La Pobla de Lillet. Lectotype: Museo de Zoologia,

Barcelona.

Distribution.—See fig. 2 .

Description.—Shell slender, more or less cylindro-conical to fusiform, with 1¼–1 3/4 protoconch whorls and an additional 7 7/8 to 8 5/8 whorls, sculptured with fine, regularly placed axial ribs. Body whorl obliquely flattened, slightly narrowed, with a very indistinct keel. Palatalis superior accompanied by a clear external indentation of the apertural lip. Palatal side of the aperture slightly leaning forward (in lateral view). Height, 8.2–10.9 mm; width, 2.4–3.1 mm. Greatest width at approximately half the height of the shell. Umbilicus narrowly open.

Apertural lip moderately to strongly thickened; its parietal edges connected by a very faint callus. Angularis and spiralis connected by a faint callus or not at all. Subangularis present, partly attached to angularis. Parietalis and often a faint to strong infraparietalis are present. Columellaris reaching slightly to clearly beyond the columella in front, front end not truncated. Infracolumellaris and columellaris equally well developed. Infrapalatalis, palatalis inferior and palatalis superior hardly to clearly incised or interrupted, reaching up to the edge of the aperture. At the anterodorsal palatal center, a suprapalatalis and often a suturalis are present.

Genetic barcode.—GenBank accession numbers EU395385 – EU395393 .

Notes.— Abida s. lilietensis is somewhat variable across its range, with forms that are intermediate to A. s. affinis. There can be variation in apertural shape and shell shape within a single population (i.e. pl. 3 figs E–F)
