Allodontichthys tamazulae Turner, 1946

Conservación: Allodontichthys tamazulae es evaluada por la Unión Internacional para la Conservación de la Naturaleza en la lista roja de especies amenazadas como (VU) Vulnerable (2018). Pollution from a sugar cane mill near the town of Tamazula has made a portion of the former range of the species in the lower Tamazula River uninhabitable since the 1970s (Lyons & Mercado-Silva, 2000). Additional pollution from waste water from the town of Tuxpán, and from sewage from a huge paper mill in Atenquique, wash-in of fertilizers and pesticides from ubiquitous sugar cane fields, in addition to sediment as a result of almost entire deforestation in the headwaters of the Río Atenquique (and other affluents of the Río Tuxpán), along with the Río Tuxpán itself for paper production leads to an ongoing decline in extent of occurrence, area of occupancy and quality of habitats (Köck, 2020). Recent surveys have encountered A. tamazulae at ten locations, several of which had moderately large numbers of fish, and populations appear to be stable (Lyons et al., 2019:125).
