ABSTRACT. Description of Microtendipes morii sp.n., Polypedilum (Polypedilum) mercantourus sp.n. and Virgatanytarsus rossaroi sp.n. is provided based on material collected in the Tyrrhenian Sub-Region including the continental and insular Provinces. M. morii sp.n. and V. rossaroi sp.n. are described as male adult and pupal exuviae based on associated male adults and male pharate adults, while P. mercantourus sp.n., is described only as male adult. M. morii sp.n. is occurring in lotic pristine habitats delimited by the upper basin of cold mountain streams located in central and west Corsica. P. mercantourus sp.n. is only known from two small lakes located in the Maritime Alps (E-France). V. rossaroi sp.n. is currently known from the middle basin of several streams located in both French and Italian Maritime Alps. Taxonomic remarks and comments on the ecology and geographical distribution of the new species are given.
