Goodeid Status

Table 1. Status and trends of Mexican Goodeidae in the wild as of 2017 as determined by John Lyons. “Government” refers to the legal classification by the Mexican Federal government (NOM 2002), and “Lyons” refers to my recommended designation based on IUCN (2001) terminology and criteria.

Priorities for Captive Maintenance of Mexican Goodeids

Extinct (no captive populations available):
Characodon garmani

Extinct in the Wild (captive populations available):
Skiffia francesae

Critically Endangered:
Allodontichthys polylepis (possibly extinct in the wild)
Allotoca goslinei (possibly extinct in the wild)
Allotoca maculata
Allotoca meeki
Allotoca zacapuensis
Ameca splendens
Ataeniobius toweri
Chapalichthys pardalis
Chapalichthys peraticus
Characodon audax*
Characodon lateralis*
Girardinichthys viviparus
Hubbsina (Girardinichthys) ireneae
Hubbsina (Girardinichthys) turneri (possibly extinct in the wild)
Neotoca (Skiffia) bilineata
Neophoorus (Allotoca) regalis
Xenoophorus captivus*
Zoogoneticus tequila

Allodontichthys hubbsi
Allotoca dugesii*
Skiffia lermae
Skiffia multipunctata*
Xenotoca eiseni*
Zoogoneticus purhepechus
Zoogoneticus quitzeoensis

Allotoca diazi
Girardinichthys multiradiatus

Allodontichthys tamazulae
Allodontichthys zonistius
Alloophorus robustus*
Allotoca catarinae*
Chapalichthys encaustus
Goodea gracilis (= G. atripinnis?)
Ilyodon cortesae
Ilyodon whitei* (inc. I. lennoni)
Xenotaenia resolanae
Xenotoca melanosoma

Relatively Secure:
Goodea atripinnis* (inc. G. luitpoldi)
Ilyodon furcidens* (inc. I. xantusi)
Xenotoca variata*
