Abstract
While originally intending to explore the venom gland microbiome of the desert hairy scorpion Hadrurus arizonensis Ewing, 1928, nanopore sequencing serendipitously recovered complete mitochondrial genomes for this iconic arachnid. Phylogenetic analysis of these high-quality genomes places Hadrurus as sister to Uroctonus, in agreement with some phylogenomic hypotheses. Additionally, we reveal significant genetic variation among individuals from the same population, highlighting the potential of mitogenomics for population genetics and phylogeography. This study showcases the effectiveness and affordability of nanopore sequencing for research with non-model organisms, opening new avenues for investigating arachnid biodiversity, evolution, and biogeography.
