À propos de quelques Bibionidés boréo-alpins, dont Bibio brunnipes (Fabricius, 1794), espèce nouvelle pour la faune de France (Diptera, Bibionidae)

Note about some boreo-alpine March-flies, with special reference to Bibio brunnipes (Fabricius, 1794), new species for the fauna of France (Diptera, Bibionidae). The presence in France of the boreo-alpine species Bibio brunnipes (Fabricius, 1794) is ascertained for the first time from localities in department Hautes-Alpes, at altitudes of 2300-2480 m. A preceding record of the species from a low altitude locality is discarded, as it is based on a wrong identification. The presence of the species in Hungary, based on a wrong attribution of locality, is discarded. A new locality in the Alpes-de-Haute-Provence is given for the rarely observed B. lautaretensis Villeneuve, 1924. The situation in France of B. brunnipes, B. lautaretensis and a third boreo-alpine bibionid, Dilophus borealis Skartveit, 1993, is discussed.
