A biogeographical analysis of the polychaetes (Annelida: Polychaeta) from the gulf of Tehuantepec, México.
The biogeographic affinities of 84 species of annelid polychaetes collected in the continental shelf of the Gulf of Tehuantepec are surveyed in this study. Four predominant faunistic assemblages were found: Wide distribution (24,99%), Amphiamerican (21,42%), Pacific (42,84%) and Disjunct (10,91%); those were defined from the eleven most generalized groups found there (Cosmopolitan, Circumtropical, Amphiamerican extended, Amphiamerican warm waters, Northeastern Pacific, Eastern tropical Pacific, Indopacific, Transpacific, Amphiamerican-Eastern Atlantic, Amphiamerican-Western Pacific, Eastern Pacific-Eastern Atlantic). The distribution patterns as well as the migration hypotheses that might explain the present distribution are discussed, and comparisons are made with recent biogeographic studies in nearby areas in the eastern Pacific such as Panama, Colombia and western Mexico.

En este trabajo se analizan las afinidades biogeográficas de 84 especies de anélidos poliquetos recolectados en la plataforma continental del golfo de Tehuantepec. Se encontraron cuatro componentes faunísticos dominantes: Amplia distribución (24,99%), Anfiamericano (21,42%), Pacífico (42,84%) y Disyunto (10,91%) definidos a partir de once grupos principales (Cosmopolita, Circuntropical, Anfiamericano Extendido, Anfiamericano en aguas cálidas, Pacífico Nororiental, Pacífico Oriental Tropical, Indopacífico, Transpacífico, Anfiamericano-Atlántico Oriental, Anfiamericano-Pacífico Occidental y Pacífico Oriental-Atlántico Oriental). Se discuten los patrones de distribución y la hipótesis de migración que pudieran explicar la distribución de los anélidos poliquetos presentes en esa área, y se compara la distribución de los grupos principales con estudios de Áreas cercanas del Pacífico, como Panamá, Colombia y la costa oeste de México.
