Skiffia is a genus of goodeid fish that contains four species, endemic to the Mesa Central area of Mexico.

They typically have a limited tolerance to environmental degradation, and so are susceptible to anthropogenic disturbance. The exception to this is Skiffia bilineata, which is comparatively more tolerant to eutrophication, turbidity and seasonal changes in environmental conditions [1]. All four Skiffia species face some conservation threat and have suffered local extinctions in more than 50% of areas studied where they were previously known to have existed [1]. Skiffia lermae and Skiffia bilineata are the most widely distributed of the genus, found over the states of Michoacán, Jalisco and Guanajuato. Skiffia multipunctata has a restricted distribution in Michoacán and Skiffia francesae has been declared extinct in the wild by the IUCN [2][1]. There is only one locality from which captive S. francesae stocks have been derived (Teuchitlán). Captive populations of S. francesae are maintained in a variety of locations by aquarium hobbyists, research institutes and zoos. The history of this particular species is unclear, but they are believed to have descended from one stock collected by Dr. R. Miller in 1976 [3]; it appears that no other stocks descended from independent samples from this region.

[edit] Species

There are four described species[4]:

  • Twoline skiffia, Skiffia bilineata (Bean, 1887[5].
  • Golden skiffia, Skiffia francesae Kingston, 1978[6].
  • Olive skiffia, Skiffia lermae Meek, 1902[7].
  • Spotted skiffia, Skiffia multipunctata Pellegrin, 1901[8].
