Potamalpheops Tyrymembe
''Potamalpheops'' is a genus of Caridea, shrimp in the family (biology), family Alpheidae. It was originally erected by Powell in 1979 to house species from Africa. Later, Horton H. Hobbs, Jr. realised that the troglobite, troglobitic shrimp he had described in 1973 from Oaxaca, Mexico as ''Alpheopsis stygicola'', also belonged to the genus, and in 1991, A. J. Bruce described a new species from Australia, further expanding the genus' geographical range. It is now thought to represent a Relict (biology), relict taxon from the Tethys Sea. The following species are currently accepted as valid: *''Potamalpheops amnicus'' *''Potamalpheops darwiniensis'' *''Potamalpheops galle'' *''Potamalpheops hanleyi'' *''Potamalpheops haugi'' *''Potamalpheops johnsoni'' *''Potamalpheops kisi'' *''Potamalpheops miyai'' *''Potamalpheops monodi'' *''Potamalpheops nazgul'' *''Potamalpheops palawensis'' *''Potamalpheops pininsulae'' *''Potamalpheops pylorus'' *''Potamalpheops stygicola'' ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
