| Abstract | Gila eremica is described from drainage basins of the Sonora, Mitape, and upper Yaqui rivers of northwestern Sonora, Mexico. It differs from its nearest relative G. purpurea, with which it has been long confused, in having a larger mouth, a smaller distance between the origins of pectoral and pelvic fins, and a more slender caudal peduncle. Gila eremica and G. purpurea are allopatric in the Rio Yaqui basin. The new species differs from G. ditaenia, of the adjacent Rio de la Concepcion, in both meristic and morphometric features. Gila eremica, es descrita por primera vez en las cuencas de los rios Sonora, Matape y en la parte alta del Yaqui, en el noroeste de Sonora, Mexico. Esta especie, se caracteriza por tener una boca mas grande que su pariente mas cercano, G. purpurea, con quien ha sido largamente confundida, ademas de que la primera posee una distancia menor entre los origenes de la aleta pectoral y pelvica, y un pedunculo caudal mas delgado. Gila eremica y G. purpurea son alopatricas en la cuenca del Rio Yaqui. La especie nueva difiere tanto meristicamente como morfometricamente de G. ditaenia, encontrada en el cercano Rio de la Concepcion. |
