Taxon classification Animalia Stylommatophora Orthalicidae

Genus Clathrorthalicus Strebel, 1909

Orthalicus (Clathrorthalicus) Strebel 1909: 150.

Type species.

Orthalicus wallisi Strebel, 1909, by original designation (Strebel 1909: 102).

Diagnosis.

Shell ovate-conic, thin, whorls slightly convex, apex rather blunt, height up to ca. 30-45 mm (study area), colour of early whorls uniformly pink, yellowish or greyish-brown, the last whorls with dark radial streaks interrupted by 2-3 light bands, typically on the penultimate whorl with a subsutural band on a lighter ground colour, protoconch pitted, teleoconch with growth striae and delicate spiral lines, aperture ovate, peristome expanded, parietal wall brown (modified after Schileyko 1999).

Distribution.

Colombia, Ecuador.

Habitat.

Probably living in trees, as far as known in cloud forests (Figs 85 E–F, 86 D–F).

Remarks.

This genus is scarcely represented in (historical) collections, and only recently some of its taxa were transferred to it and Strebel’s taxon given generic status (Breure and Ablett 2015). Further morphological and molecular studies should clarify its systematic position.
