DNA barcodes were obtained for the species delimitation and matching. A partial fragment of the mitochondrial cytochrome oxidase subunit I (COI) gene was amplified and sequenced for all species using the primers LCO1490-oono (5’-CWACAAAYCATARRGATA-TTGG-3’) and C1-N-2776 (5’-GGATAATCAGAATANCGNCGAGG-3’). For additional information on extraction, amplification and sequencing procedures, see Zhao and Li (2017). All sequences were analyzed using BLAST and are deposited in GenBank. The accession numbers are provided in Table 1.
