Resumen
One hundred and forty six species of polychaetes belonging to 35 families were identified from material collected from 25 subtidal sample sites in the Gulf of Nicoya. One hundred and twenty five of these species were present in multireplicate collections taken seasonally at four stations with contrasting sedimentary environments. The three most commonly collected species at these four stations were the capitellids Mediomastus californiensis? and Notomastus luridus and the spionid Prionospio mulfibranchiata. These results indicate that the polychaete fauna of the Gulf of Nicoya has not been adequately characterized and may be of greater species richness than previously reported. Se identificó 146 especies de poliquetos de 35 familias en 25 estaciones submareales del Golfo de Nicoya; de ellas 125 aparecieron en muestreos multiples tomados estacionalmente en cuatro estaciones con diferentes tipos de sedimento. Las tres especies más comúnmente recolectadas en esas estaciones fueron los capitélidos Mediomastus californiensis? y Notomastus luridus y el espiónido Prionospio multibranchiata. Aparentemente la fauna de poliquetos del golfo no ha sido adecuadamente descrita y puede ser mucho más biodiversa de lo que se creía.
