Pomacea columellaris is a South American species of freshwater snail in the apple snail family, "Ampullariidae".
Taxonomy.
"Pomacea columellaris" was originally described as "Ampullaria columellaris" by Augustus Addison Gould in 1848, based on a holotype shell collected during the United States Exploring Expedition from 1838-1842. They were named for their notable columella, comparable to those of "Helix" land snails. In 1904, Dall proposed a section or subgenus of "Ampullaria" (later treated as synonymous with "Pomacea") called "Limnopomus", with "A. columellaris" as the type species. After 1991, "Limnopomus" was also considered synonymous with "Pomacea".
Shell description.
The species has a heavy, oval shell with a sharp spire. Its operculum is corneous and able to retract inside the shell's aperture. They lack an umbilicus and are often yellow in color.
Distribution.
"P. columellaris" is found in rivers in the highlands of Venezuela, Colombia, Ecuador (Pastaza Province), and Peru.
