English. The following studies comprise a systematic registry of monogeneous species, Dactylogyridae and Ancyrocephalinae, collected from the gills of fishes pertaining to the Pimelodidae, Poeciliidae, Cichlidae, and Characidae families found in many rivers of the Atlantic Coast of Nicaragua during 1999. Most of the monogeneans presented morphological similarities with respect to those previously described that were discovered in the southeast of Mexico. Some aspects concerning the geographical distribution of all the taxa that have been found are briefly discussed. From a geographical point of view, these discoveries support the idea that fish migration through Central America to Mexico has occurred simultaneously with their monogeneans.

El presente estudio comprende un registro sistemático de especies de monogéneos (Dactylogyridae, Ancyrocephalinae) colectados de las branquias de peces de las familias Pimelodidae, Poeciliidae, Cichlidae y Characidae, en algunos de los ríos de la Costa Atlántica de Nicaragua en 1999. La mayoría de los monógenos encontrados son morfológicamente similares respecto a aquellos previamente descritos en el sureste de México. Algunos aspectos sobre la distribución geográfica de todos los taxa encontrados se discuten brevemente. Desde el punto de vista zoogeográfico, estos hallazgos apoyan la idea de que la migración de los peces a través de América Central hacia México ha ocurrido simultáneamente con sus monógenos.
