Potamalpheops

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]
