A species identification key is proposed. The genitalia, the habitus and genital segments of the abdomen of both sexes are represented. H. haunoldiana (Bernhauer) et H. perpusilla (Scheerpeltz) are reported from France for the first time. One species is rehabilitate: H. libitina (Mulsant & Rey). Four new species are described and illustrated: H. jarrigei n. sp., H. lecoqi n. sp., H. serrula n. sp. et H. fragilis corsicana n. subsp. The following synonyms are established : H. delicatula (Heer) = H. moraviae G. Benick, syn. junior; H. subtilissima (Kraatz) = H. pyrenaea (Scheerpeltz) syn. junior; H. tenuissima (Eppelsheim) = H. rhodani G. Benick syn. junior = H. tristicolor G. Benick syn. junior = (must be confirmed) H. paratenuissima (G. Benick) syn. junior.
