SYNOPSIS A case of infection by Helicosporidium parasiticum Keilin, 1921, in a hepialid caterpillar from Argentina is described. The pathogen produces deep proliferation starting from a cuticular callus, with numerous cysts occluded by multiple fibrous layers of connective tissue. Other cysts encapsulated in layers of lymphocytes and cysts in the lobes of the fat body are present in different parts of the body. Centers of melanization occur in most cysts. The pathway of infection, the reaction of the host and some structural features of the parasite are typical for fungus infections. Transfer of the genus Helicosporidium from Protozoa to primitive Ascomycetes, Saccharomycetaceae, is proposed.
