Resumen

En el golfo de Gabès (sur de Túnez, Mediterráneo central) se encuentran dos especies del género Squalus: el galludo Squalus blainvillei (Risso, 1827) y otra de morro más corto perteneciente al grupo Squalus megalops-cubensis. Los datos morfométricos y merísticos junto con el análisis genético (ADN Inter Simple Sequence Repeats markers y métodos moleculares Barcoding) apoyan la identificación de esta última especie como Squalus megalops (Macleay, 1881). Squalus megalops se encuentra en aguas australianas templadas y tropicales, y se piensa que habita también en el Atlántico este, en el océano Índico sur y en el Pacífico noroccidental, aunque estos registros deben ser confirmados. Nuestro estudio confirma su presencia en el mar Mediterráneo. La descripción tanto de S. blainvillei como de S. megalops está basada en especímenes capturados en aguas tunecinas.
