Notes.

This species was found attached to the posterior hindgut or anal gills of larval Simuliidae hosts, where we also found P. chattoni . In Bulgaria, the species was quite common in the black fly hosts dissected. All the individuals had the typical characteristics of the species ( Dang and Lichtwardt 1979), with a holdfast placed on the incurved section of the thallus. This species is known from USA ( Dang and Lichtwardt 1979), Sweden ( Lichtwardt 1984), Armenia ( Nelder et al. 2005), Canada ( Strongman and White 2008), Spain (Valle and Santamaria 2009, Valle 2014b), Italy ( Valle et al. 2014). P. curvum is probably very common and cosmopolitan as their hosts, but their thalli can be easily overlooked when attached to or near to the anal gills.
