Distribution

[edit]

This species is endemic to the West Indian island of Dominica.[3]

The type locality is Long Dilton, Dominica.[1][3] The holotype is in National Museum of Natural History under number 535857.[3]

Shell description

[edit]

Amphicyclotulus dominicensis has spiral cords which are clearly visible and raised.[3]

There are only two species in the genus Amphicyclotulus in Dominica.[3] The other species is Amphicyclotulus amethystinus, which has either no spiral threads or ones that are only weakly present.[3]

Amphicyclotulus dominicensis is smaller than the Amphicyclotulus amethystinus.[3] Amphicyclotulus dominicensis is more coarsely sculptured and has a higher spire.[3] It has been found on the leeward and windward sides of the island of Dominica, at low elevations only.[3]
