New distributional data from France for two European endemic species, Seligeria carniolica and S. irrigata, are provided. The latter is new to France and this discovery significantly extends its current geographical range. The former is red-listed as an endangered endemic species in Europe and for a long time it was known only from some widely distributed isolated localities but nowadays it appears to be quite well represented in eastern France. The biogeography of these two species is discussed and S. carniolica, formerly considered as a boreal-montane suboceanic element, could be better designated as a Perialpine species with disjunct, highly isolated occurrences in northern Europe and in the Balkan Peninsula. Seligeria irrigata is primarily an Alpine species with some isolated localities in the Western Carpathians of Slovakia and in the Abruzzean Apennine Mountains in Italy.
