Amphibulima patula is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Amphibulimidae.

Subspecies

Subspecies of Amphibulima patula include:

Amphibulima patula patula (Bruguière, 1792)
Amphibulima patula dominicensis Pilsbry, 1899[2] - Pilsbry (1899) separated the Dominican specimens on the basis of the darker colour and by having a heavier sculptured shell.[3] Robinson et al. (2009)[3] have found living specimens that were either light beige-coloured with a somewhat orange-yellowish line along the foot (see photo on the left), or entirely dark brown coloured (see photo on the right).[3]

Distribution

The nominate taxon Amphibulima patula patula has been reported from Guadeloupe (probably now extinct) and Marie-Galante.[3] The type locality is Guadeloupe.

Amphibulima patula dominicensis is endemic to Dominica.[3]

Another variety has been reported from Saint Kitts and Saba.[3]

Description

Amphibulima patula has large foot, that is not completely retracted into the shell in living specimen.[2] But when the live animal is immersed into the preserving fluid, then it retracts completely within the shell.[2]

Adult snail is about 2.5 cm.[4] It is called a slug-like snail because the shell is relatively small in proportion to the body and with one large, ear-like whorl and two small whorls.[4] Color is yellowish brown.[4]

This species could be confused with the common amber snails (Succinea), especially the juveniles.[4] The Amphibulima has much coarser sculpture than the amber snails.[4]

The jaw and radula of Amphibulima patula dominicensis was described by Bland & Binney in 1874.[5]

Ecology

Amphibulima patula dominicensis is frequently found on banana and Citrus plants, where it may feed on the leaves.[3] They also eat leaves of Virginia pepperweed Lepidium virginicum and Cakile lanceolata.[2] They eat lettuce in captivity.[2]
