Pachybrachis holerorum (Coleoptera: Chrysomelidae: Cryptocephalinae), a new species from the Apennines, Italy, identified by integration of morphological and molecular data.

摘要: Pachybrachis holerorum n. sp. is described from the northern Apennines, Italy. The new species related to P. karamani (Weise, 1893), which it differs in shape of median lobe aedeagus and small differences chromatic pattern. close relationship with confirmed by molecular analyses performed on a fragment 829 nucleotides mitochondrial gene Cytochrome c oxidase subunit 1 ( cox1 ). general mixed Yule-coalescent model, developed for delimitation using single-locus data, was applied phylogeny order test hypothesis as separate species. Information host plants, acquired during specimen collection, gut content, targeting plastid large ribulose-bisphosphate carboxylase trnL (UAA) intron. Besides, lectotype designated.
