摘 要:European mountain systems have played a crucial role in shaping the distribution of species and of their genetic diversity during the Quaternary climatic changes,with the establishment of allopatric patterns across main mountain *** we investigated the evolutionary history of fea beetles of the Longitarsus candidulus species-group showing an uncommon disjunct biogeographic pattern across the Apennine and the *** applied a multilocus molecular approach and multispecies coalescent models to establish a phylogenetic and systematic framework for this morphologically homogeneous species-group and to estimate the time of main cladogenetic events underlying the origin of the Apennine-Pyrenees *** found strong support for the monophyly of the candidulus group with a sister relationship between Longitarsus laureolae and *** endemic to the Apennine and the Pyrenees mountains *** timing of speciation events in the candidulus species-group coincides with 2 major climatic transitions during the Early and Middle Pleistocene which resulted in signifcant environmental changes in Europe and suggest a scenario of allopatric isolation and divergence on distinct mountain *** split between the thermophilic species *** and the ancestor of the temperate species *** and *** is estimated at~3 Ma during the transition from Pliocene to Pleistocene and was probably triggered by their segregation in xerophilous and temperate *** speciation between *** and ***,estimated at~1 Ma during the Mid-Pleistocene Transition,can be explained by the establishment of unfavorable conditions in West Alps and Central Massif underlying the onset of the Apennine-Pyrenees disjunct ***,the strict association between members of the candidulus group and distinct Thymelaeaceae plants suggests further studies to address the hypothesis that speciation in these fea beetles might have been also associated with
