Original description as Skiffia francesae:

ZooBank:B189E5B6-6EF6-40D8-AECA-09B433A065B0.

Conservation: Skiffia francesae is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (EW) extinct in the wild (2018). Reported extinct in 1978 by Burkhead (2012). The reasons of the demise of S. francesae are unknown, the last collection, that of the types, dates back to 1970. Kingston (1978:507 citing Michael L. Smith) mention that in May 1977 the numbers of S. francesae were reduced drastically, probably by competition with the introduced Xiphophorus maculatus, which at the time outnumbered S. francesae in 50:1. Rio Teuchitlan has suffered both pollution and introduction of a large number of exotic species, which include Coptodon rendalli, Oreochromis aureus, Poecilia mexicana, Pseudoxiphophorus bimaculatus, Xiphophorus helleri, X. maculatus.

The population from S. francesae at El Molino spring pond near the town of Cuyucapán is now extinct after a drought in 2010 dried up the whole habitat (Lyons et al., 2019:141).
