Resumen:
Trichomycetes fungi live obligately associated with arthropod guts from all over the world. Fifteen species of Trichomycetes living in the guts of aquatic insects are reported from two provinces of Argentina at the two territorial extremes: Misiones in the Northeast, and Tierra del Fuego, the southernmost extreme of the country and of the world. Species belong mostly to the Harpellales, and they were identified from guts (hindguts and midguts) of immature stages of Culicidae, Simuliidae, Chironomidae, Ceratopogonidae (Insecta: Diptera), and Ephemeroptera and Plecoptera. Five species of Harpellales were obtained from Misiones and eight species from Tierra del Fuego. In Tierra del fuego, two of the species belong to the Order Amoebidiales. Most of the species of Trichomycetes reported here were also reported before for other hosts and regions of Argentina, however most are new records for the country and for South America. The lower diversity of Trichomycetes found at Misiones, which has a subtropical climate and rainforest vegetation, was possibly due to the warmer temperatures of the water (15--24 C), compared to the colder streams of Tierra del Fuego (9--15 C), with forests and steppes as typical vegetation.
