文摘The halictid genus Lasioglossum,as one of the most species-rich bee groups with persistently contentious subgeneric boundaries,is one of the most challenging bee groups from a systematic standpoint.An enduring question is the relationship of La-sioglossum and Homalictus,whether all halictine bees with weakened distal wing ve-nation comprise one or multiple genera.Here,we analyzed the phylogenetic relation-ships among the subgroups within Lasioglossum s.l.based on thousands of single-copy orthologs and ultraconserved elements,which were extracted from 23 newly sequenced low-coverage whole genomes alongside a published genome(22 ingroups plus 2 out-groups).Both marker sets provided consistent results across maximum likelihood and coalescent-based species tree approaches.The phylogenetic and topology test results show that the Lasioglossum and Hemihalictus series are reciprocally monophyletic and Homa-lictus and Rostrohalictus are valid subgenera of Lasioglossum.Consequently,we lower Homalictus to subgenus status within Lasioglossum again,and we also raise Rostrohalic-tus to subgenus status from its prior synonymy with subgenus Hemihalictus.Lasioglossum przewalskyi is also transferred to the subgenus Hemihalictus.Ultimately,we redefine La-sioglossum to include all halictine bees with weakened distal wing venation.
