Antillorbis is a genus of freshwater gastropods belonging to the family Planorbidae. [2] This genus is distributed throughout the tropics and subtropics of the Americas. [2]
Antillorbis species are small, between 2.5–5 mm (0.098–0.197 in) in shell width. Both species have a slight sculpture consisting of fine, spiraling lines, though this is much more common in A. aeruginosus. [3] The umbilicus is sunken, giving a concave appearance to the left and right side of the shell. The right side is less concave. [4] [5] Like the genus Drepanotrema , Antillorbis species have two flagella that attach to the base of the penis sheath. [3]
Antillorbis species are native to the Americas. A. aeruginosus can be found in North and Central America, while A. nordestensis may be found in South America. [2]
The species in this genus are as follows: [1] [2]
