Testing the systematic status of Homalictus and Rostrohalictus with weakened cross‐vein groups within Halictini (Hymenoptera: Halictidae) using low‐coverage whole‐genome sequencing

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 Lasioglossum and Homalictus, whether all halictine bees with weakened distal wing venation comprise one or multiple genera. Here, we analyzed the phylogenetic relationships among the subgroups within...
