Abstract

Mitochondrial DNA sequence data from a segment of the cytochrome b (cytb) gene were used to infer geographic distributions of two unnamed putative species of eastern Pacific bonefishes, Albula sp. A and Albula sp. C, both members of the A. vulpes complex. The molecular data revealed that Albula sp. C, a lineage originally identified from Panama, is distributed north to the coastal waters of central Mexico and the southern Gulf of California (Sea of Cortez). Albula sp. A, originally identified from the central Gulf of California and distributed to California, USA, is shown here to range to Mazatlán, Sinaloa, in the southern gulf where it occurs sympatrically with Albula sp. C. The distributions of the two putative species inferred from the molecular data suggest that the single available name for eastern Pacific bonefishes, Albula esuncula (Garman, 1899), originally described from larvae (leptocephali) collected off Acapulco, Guerrero, should be assigned to Albula sp. C. Morphometric and meristic analyses of adults of A. esuncula and Albula sp. A revealed no external characters that could be used reliably to distinguish between the two species.

Se utilizaron datos de secuencias de ADN mitocondrial obtenidos de un segmento del gen citocromo b (cytb) para elucidar las distribuciones geográficas de dos especies putativas no nombradas de macabí del océano Pacifico Oriental, Albula sp. A y Albula sp. C, que son miembros del complejo de A. vulpes. Los datos moleculares demostraron que Albula sp. C, una línea genética identificada originalmente de Panamá, se distribuye hacia el norte hasta las aguas costeras de México central y sur del golfo de California (mar de Cortés). Se demuestra que Albula sp. A, encontrada originalmente en el golfo de California central y aguas costeras del estado de California, EUA, se distribuye hasta Mazatlán, Sinaloa, en el sur del golfo donde coincide con Albula sp. C. Con base en las distribuciones de las dos especies putativas de Albula se establece que Albula sp. C debe nombrarse A. esuncula, especie descrita originalmente de larvas leptocéfalas recolectadas en la región de Acapulco, Guerrero por Garman (1899) y único nombre disponible para los macabí del Pacifico Oriental. En relación a los análisis morfométricos y merísticos de adultos de A. esuncula y Albula sp. A, no se encontraron caracteres externos que podían ser utilizados para distinguir entre las dos especies.
