José Alvarez del Villar |
b. 1903; d. 1986
Mexican ichthyologist born in Spain. As a member of the Mexican ‘Escuela
Nacional de Ciencias Biologicas’ that included Bibiano F. Osorio Tafall, he
explored the whole cave system for the area which now has about 30
localities containing Astyanax fasciatus. He described two new
populations,
in addition to the one in La Cueva Chica, giving them new specific names:
Anoptichthys antrobius for the La Cueva El Pachón population (Alvarez
1946) and A. hubbsi for the La Cueva de los Sabinos population
(Alvarez
1947). As more cave populations were discovered, it became evident that
this flow of specific names was leading nowhere and that all the
troglomorphic fish should be considered as a single species. |
