Biology:Antillorbis
Antillorbis is a genus of freshwater gastropods belonging to the family Planorbidae.[1] This genus is distributed throughout the tropics and subtropics of the Americas.[1]
Description
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.[2] The umbilicus is sunken, giving a concave appearance to the left and right side of the shell. The right side is less concave.[3][4] Like the genus Drepanotrema, Antillorbis species have two flagella that attach to the base of the penis sheath.[2]
| A. aeruginosus | A. nordestense | |
|---|---|---|
| Sculpture | More prominent | Less prominent |
| Aperture | Rounder | Oval-shaped |
| Reproductive Tract | Longer | Shorter |
| Prostate Diverticules | More | Fewer |
Distribution
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.[1]
Species
The species in this genus are as follows:[5][1]
- Antillorbis aeruginosus (Morelet, 1851)
