| - The male adult and the pupal exuviae of Corynoneura tyrrhena sp. n. are described based on associated material of male adults, male pharate adults and pupal exuviae collected in pristine mountain springs and streams (altitude 1700-1350 m) delimited by the Restonica and Asco upper basin in Corsica. The new species is distinguished from other known Palaearctic Corynoneura species on the basis of the following characters: in the male adult (antenna 8-segmented; third segment of maxillary palp spherical; sternapodeme inverted U-shaped; phallapodeme scalpel-like with median projection and caudally attached on lateral sternapodeme; tergite IX bibbed; inner margin of gonocoxite distinctly truncate, superior volsella bearing a characteristic semi-circular notch, inferior volsella smooth; gonostylus long, gradually narrowed, bent and curved inwards, megaseta long and slender); in the pupal exuviae (L-setae on abdominal segments bristle-like; posterior transverse rows of spines present on: tergites II-VIII, sternites IV-VIII; rows of hooks present on: tergites II-VI, sternites IV-VII; anal lobe diamond-like, anterior side longer, fringe restricted to the posterior part). Worldwide there are currently about 97 valid species of Corynoneura including the present description. Consequently there are now about 45 known Corynoneura species from the Palaearctic Region, of which 12 from continental France and 8 from Corsica. On the basis of the shape pattern of the phallapodeme, the male adult of the new described species should temporarily belong to the celeripes subgroup. Geographical distribution of Corynoneura tyrrhena sp. n. is currently known from the upper basin of the Restonica and Asco Rivers in Corsica. This species is considered as a true Tyrrhenian faunal element, which evolved locally perhaps during the Palaeocene (Montian) or the late Miocene. Taxonomic remarks, discussion and comments on the ecology and geographical distribution of the new species are provided.
