Lepeophtheirus Frecuens New Species and New Record of Kroyerina Meridionalis Ramirez, 1975 and New Hosts Record for Lepeophtheirus Chilensis Wilson, 1905 (Copepoda: Siphonostomatoida) Parasitic on Fishes of Chile, South America
Abstract:Lepeophtheirus frecuens, a new species of parasitic copepod from Oplegnathus insignis (Kner) type host fish and other host fishes of the inshore waters of Antofagasta, Chile, is described and illustrated. The new species is separated from its short abdomen congeners by the first maxilla with the medial tine shorter than the lateral one and by a series of differences in its appendages, particularly the second antenna of the male.
New host species for Lepeophtheirus chilensis Wilson, 1905 are named. The range of Kroyerina meridionalis Ramirez, 1975 is extended from the Mar del Plata, South Atlantic to the South Pacific coast of Antofagasta, Chile. Some comments about the morphology and morphometric characters of these two species are made.
