shows an additional molecular differentiation, as specimens from Jasper National Park, Alberta, Canada were found to belong to a separate barcode BIN (BOLD:ABA1601), and the remaining sequences, both from western and eastern parts of North America represent another barcode BIN (BOLD:AAV1805). The phylogenetic relationship between these clades is not resolved in the molecular tree and lowly supported (Bootstrap: 65) in our analysis.
