Molecular phylogeny of M acrolycus ( C oleoptera: L ycidae) with description of new species from C hina

M acrolycus is a genus of net‐winged beetles with 69 species distributed in the eastern P alearctic and northernmost part of the O riental region. The first molecular phylogeny of M acrolycus was produced using an rrn L  +  t RNA ‐ L eu  +  nad1 mt DNA fragment. The major lineages and species limits were identified with morphology and molecular data. We propose that C erceros is a subgenus of M acrolycus to enable identification of all adult specimens in the genus without DNA sequencing. Two species groups are proposed in M acrolycus s. str. and six in C erceros . Additionally, twelve M acrolycus species are newly described from C hina: M . aquilinus , M . baihualingensis , M . bicolor , M . guangxiensis , M . jianfenglingensis , M . kuatunensis , M . lizipingensis , M . parvus , M . phoeniceus , M . rhodoneurus , M . rosaceus and M . sichuanensis . M acrolycus holzschuhi is proposed to be a junior subjective synonym of M .  jeanvoinei . The highest diversity of M acrolycus is found in southern C hina. The species from the main islands of Japan are placed in two species groups: M .  excellens is a sister to remaining species of the M .  murzini group and the M .  flabellatus group is a monophylum of closely related species in a sister position to the M . bicolor group.
