A cosmopolitan or sub-cosmopolitan species, widespread in the Northern Hemisphere, it is common in European localities where their hosts were available. It has been found attached to the peritrophic matrix of Simuliidae larvae in different Bulgarian localities. Our specimens have the typical characteristics of the species, distinguishable on the basis of trichospore morphometry (Fig. 14 ) and holdfast structure (Fig. 15 ) ( Leger and Duboscq 1929a ). The trichospores in our specimens measured 50-60 x 6-7 μm and were variable in shape, from nearly straight to allantoid or slightly coiled.
