摘要：

A new species of Dichotrachelus is described from the Carnian Alps, Friuli-Venezia Giulia, north-eastern Italy (type locality: Moggio Udinese, Mount Sernio). The new species belongs to the D. luzei species group, previously known from Mt. Pasubio, Veneto, and Mt. Grintavec, Slovenia; its discovery in the Carnian Alps fills thus a broad gap in the distribution of this group. It is associated with Saxifraga caesia in limestone habitats; imagoes, apparently hatching in late summer, live in the small clumps of the host plants; some larvae were found among the roots. Additional specimens moderately distinct were found in the Julian Alps: taxonomic relationships between these and the type specimens of D. kahleni are discussed. (C) 2007 WILEY-VCH Verlag GmbH & Co.
