Fourteen species of Trichomycetes living in the guts of aquatic isnects are reported from two provinces of Argentina, Misiones and Tierra del Fuego. Twelve of the species belong to the Harpellales abd two are Amoebodiales. Five harpellid species are reported from Misiones in the extreme northeast of the country (Genistellospora homothallica, Harpella tica, Smittium culisetae , Smittium sp Stachylina sp) and seven are from Tierra del Fuego , the southern tip of South America (H. meridianalis, Glotzia sp., S. culicis , S. cellaspora, S. imitatum, Stachylina minima, Penella simulii) . Insect hosts all were inmature stages of Culicidae, Simulidae, Chironomidae, Ceratopogonidae (Insecta: Diptera), Ephemeroptera and Plecoptera . The lower diversity of Trichomycetes found at Misiones , which has a subtropical climate and rainforest vegetation, was due possibly to the warmer temperatures of the water (15- 24 ºC) , copared with the colder streams of Tierra del Fuego (9-15ºC) with forests and steppes as typical vegetation.
