Potamalpheops
Genus of crustaceans
From Wikipedia, the free encyclopedia
Potamalpheops is a genus of shrimp in the family Alpheidae. It was originally erected by Powell in 1979 to house species from Africa.[1] Later, Horton H. Hobbs, Jr. realised that the troglobitic shrimp he had described in 1973 from Oaxaca, Mexico as Alpheopsis stygicola, also belonged to the genus,[1] and in 1991, A. J. Bruce described a new species from Australia, further expanding the genus' geographical range.[2] It is now thought to represent a relict taxon from the Tethys Sea.[2]

An undescribed species from Taiwan thought to belong to this genus, dubbed the "purple zebra shrimp" or "purple crystal shrimp", is sometimes kept in aquaria.[11][12][13] Its mitogenome was studied in 2024. The following cladogram is based on this 2024 study:[14]
