Helicina guppyi is a species of tropical land snail with an operculum, a terrestrial gastropod mollusk in the family Helicinidae.

Shell description

The species is smaller and lower-spired than the other Dominican Helicina species, and always has a dull brown colour, a paler aperture and a hairy periostracum; ‘covered with a velvety epidermis’, weakly keeled, with a columellar denticle. [2] Its size is 5-8.5 mm. [2] [ clarification needed ]

Distribution

This species lives in Guadeloupe, Dominica and in Martinique. [2]

This is the most common of the helicinids in Dominica, but generally restricted to the leeward side of the island. [2]

Taxonomy

Robert John Lechmere Guppy (1868) [3] described two taxa from Dominica based on shell variation within this species; both names were preoccupied. [2] William Harper Pease (1871) [1] provided a substitute name in his treatment of Indo-Pacific species. [2] This species was placed in the subgenus Striatemoda by Horace Burrington Baker (1940) [4] based on Guppy’s (1868) comparison with the Puerto Rican Alcadia subfusca (Menke, 1828), and also on Pilsbry’s (1892) [5] erroneous placement of this species with the Hispaniolan Alcadia rufa (L. Pfeiffer, 1857). [2] There is expected the forthcoming revision of the Lesser Antillean Helicinidae by Ira Richling (from Kiel, Germany). [2]

Ecology

This species is usually collected on the trunks of trees, where it is well camouflaged on tree bark, or among detritus and leaves on the ground. [2]
