Original language description

Seven microsporidian species infecting caddis fly larvae, corresponding to conventional genera Episeptum, Pyrotheca and Cougourdella were studied using light and electron microscopy. Parts of their small subunit, ITS and large subunit ribosomal RNA geneswere sequenced and compared with sequences of rDNA obtained from syntype slides of Cougourdella polycentropi Weiser 1965 and Pyrotheca sp. from Hydropsyche pellucidula. All studied caddis fly microsporidia form a closely related group. Their developmental stages in trichopteran hosts are restricted to fat body cells and oenocytes and have isolated nuclei. In late merogony, uninucleate meronts and binucleate plasmodia are formed. In sporogony a sporogonial plasmodium with four nuclei gives rise by rosette-like budding to four sporoblasts within a non-persistent sporophorous vesicle. Sporoblasts mature into pyriform to lageniform spores. The shape and size of spores, the number of polar filament coils, the structure of the polaroplast an
