DNA was extracted from the head capsules and pronota of specimens using a Qiagen DNeasy Blood & Tissue Kit following the manufacturers protocols. Extractions were performed in a sterilized laminar flow hood to minimize contamination. After DNA extraction, voucher specimens were rearticulated and card-mounted. Unique identifiers were assigned to each voucher specimen for linking back to sequence data in the Sequence Read Archive. All voucher specimens are preserved in the Purdue Entomological Research Collection and the Museum and Institute of Zoology Polish Academy of Sciences. Extracts were sent to Daicel Arbor Biosciences for library preparation and targeted enrichment using a MyBaits probe kit designed to capture 618 protein-coding genetic loci. Libraries were sequenced on a NovaSeq 6000 system using 150 bp paired-end runs.
