Biology:Potamalpheops

From HandWiki

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]

The following species are currently accepted as valid:[3]

  • Potamalpheops amnicus Yeo & Ng, 1997[4]
  • Potamalpheops darwiniensis Bruce, 1993
  • Potamalpheops galle Anker, 2005[5]
  • Potamalpheops hanleyi Bruce, 1991[2]
  • Potamalpheops haugi (Coutière, 1906)
  • Potamalpheops johnsoni Anker, 2003[6]
  • Potamalpheops kisi Marin, 2021[7]
  • Potamalpheops miyai Yeo & Ng, 1997[4]
  • Potamalpheops monodi (Sollaud, 1932)
  • Potamalpheops nazgul Christodoulou, Iliffe & De Grave, 2019[8]
  • Potamalpheops palawensis Cai & Anker, 2004
  • Potamalpheops pininsulae Bruce & Iliffe, 1992[9]
  • Potamalpheops pylorus Powell, 1979
  • Potamalpheops stygicola (Hobbs, 1973)[1]
  • Potamalpheops tigger Yeo & Ng, 1997[4]
  • Potamalpheops tyrymembe Soledade, Santos & Almeida, 2014
  • Potamalpheops yamakawai Yamashita, Komai & Koreeda, 2024[10]

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]
