Original description as Heterandria tuxtlaensis:


  • Mceachran, John D & T.J. Dewitt. 2008. "A new livebearing fish, Heterandria tuxtlaensis, from Lake Catemaco, Veracruz, Mexico (Cyprinodontiformes: Poeciliidae)". Zootaxa. (1824):45-54 (ffm00267) (abstract)

Conservation: Pseudoxiphophorus tuxtlaensis is not evaluated by the international union for the conservation of nature in the iucn red list of threatened species. Lake Catemaco remains in relatively good shape, and in spite of the exotic Oreochromis sp., the population of the different species appears to remain stable.
