Original description as Xiphophorus continens:


  • Rauchenberger, Mary & K.D. Kallman, D.C. Morizot. 1990. "Monophyly and geography of the Río Pánuco Basin swordtails (Genus Xiphophorus) with descriptions of four new species". American Museum Novitates. (2975):1-41 (ffm00052) (abstract)

Conservation: Xiphophorus continens is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (DD) data deficient (2019). Although the area of distribution of X. continens is preserved in relatively good condition, mainly by its remoteness, given its small extension it is prone to suffer alterations by further deforestation around the main spring — recently its eastern part has been deforested for agriculture, as well as the introduction of exotic species, common now in other areas of the Pánuco. In recent years, Poeciliopsis gracilis has been introduced to some areas of the Gallinas River, in my estimation causing a decrease in the numbers of Poecilia mexicana.
