    Se describe a Cryptobia neghmei sp.n., un protozoo sanguíneo de dos especies de lenguados, Paralichthys microps y P. adspersus, habitantes de la costa de Chile en el sur-este del océano Pacífico. Los protozoos flagelados son de forma elongada, delgados con dos flagelos y una membrana ondulante conspicua. Esta especie se distingue de aquellas descritas previamente en base a su forma y dimensiones inusuales. Los 97 lenguados revisados estaban infectados. Se observaron otros estados de desarrollo de protozoos kinetoplástidos en la sanguijuela Glyptonotobdella sp. que parasitaba a los lenguados y que probablemente sea el vector del protozoo

    Cryptobia neghmei sp.n. is described from the blood of two species of flounder, Paralichthys microps and P. adspersus, inhabiting the Chilean coast in the southern Pacific Ocean. Flagellates were elongate, slender, with two flagella and a conspicuous undulating membrane. It was distinguished from previously described species on the basis of its unusual shape and dimensions. All of 97 flounder were infected upon examination. Developmental stages of kinetoplastid protozoans, perhaps C. neghmei sp. n., were observed in some leeches Glyptonotobdella sp. that were found attached to flounder, which probably represent a mode for transmission among piscine hosts
