Resumen El presente trabajo reporta, por primera vez para Peru y la region sudamericana, a la prasinofita Picocystis salinarum R. A. Lewin en las Salinas de Chilca (lagunas La Milagrosa y La Mellicera), Canete, Lima. Se realizaron colecciones de estos ecosistemas acuaticos costeros-someros en 2014 y 2015; la gradiente de salinidad estuvo en el rango de 120 a 172 ‰ y pH entre 8,06-8,41; adicionalmente se tienen otros registros que confirmarian que se trata de una microalga eurihalina. El aislamiento y cultivo de P. salinarum en medio f/2 fue clave para su identificacion taxonomica, puesto que esta microalga exhibio polimorfismo en condiciones deficit de nutrientes con variacion en su morfotipo esferico a trilobulado; este ultimo corresponde al fenotipo distintivo del genero. P. salinarum fue dominante en las Salinas de Chilca sugiriendo que posee mecanismos de resistencia al estres salino, ademas de la escasez de competidores y predadores herbivoros. Palabras clave: picoplancton, prasinofita, morfotipo trilobulado, cultivo. Abstract The present work reports, for the first time for Peru and the South American region, the prasinophyte Picocystis salinarum R. A. Lewin in Salinas de Chilca (La Milagrosa and La Mellicera lagoons), Canete, Lima. Collections of these coastal-shallow aquatic ecosystems were made in 2014 and 2015; the salinity gradient was in the range of 120 to 172 ‰ and pH between 8.06-8.41; in addition there are other records that would confirm that it is a euryhaline microalgae. The isolation and cultivation of P. salinarum in f/2 medium was key for its taxonomic identification, since this microalga exhibited polymorphism in nutrient deficit conditions with variation in its spherical morphotype to trilobed; the latter corresponding to the distinctive phenotype of the genus. P. salinarum was dominant in Salinas de Chilca, suggesting that it has mechanisms of resistance to saline stress, in addition to the shortage of competitors and herbivorous predators. Keywords: picoplankton, prasinophyte, trilobed morphotype, culture.
