Supplementary Table S1. Collection data and GenBank accession numbers for taxa analyzed in gene junction portion of this study. No species names have been assigned to taxa in the subfamily Keratoisidinae, pending further taxonomic study. Specimen numbers beginning in “C0” are from the Museum and Art Gallery of the Northern Territories, Australia; remaining samples were collected by the authors. NAP = no PCR amplification product observed; √ = PCR amplification product observed but not sequenced.
