Alcadia euglypta is a minute species of operculate land snail in the family Helicinidae. The species is endemic to eastern Cuba and was first described by Clench & Aguayo in 1950.[2]
Taxonomic placement
[edit]The ordinal and familial placement of A. euglypta follow the modern neritimorph classification summarised by Richling (2004).[3]
Description
[edit]Boss & Jacobson (1973) give the following diagnostic characters:[4]
- Shell depressed-trochiform, thin and translucent, glossy horn-coloured to pale straw.
- Height up to 3.5 mm; maximum diameter 5.5 mm.
- 5–5½ slightly convex whorls with fine incremental striae and faint spiral microsculpture; a weak peripheral angulation may be present.
- Spire low; apex obtuse.
- Aperture oblique, broadly semicircular; peristome thin, not markedly expanded.
- Columellar callus thin, not dentate; umbilicus covered.
- Operculum multispiral, calcareous.
Distribution and habitat
[edit]The type locality lies in the Sierra Maestra (then Oriente Province, now Santiago de Cuba/Granma provinces), eastern Cuba.[2] Subsequent records are confined to montane limestone outcrops in the same region.[4]
Conservation status
[edit]As of September 2025 the species has not been assessed by the IUCN Red List. Given its narrow range and the continuing loss of native forest in eastern Cuba, Boss & Jacobson (1973) considered the taxon “potentially vulnerable,” but no quantitative data exist.[4]
