All specimens were examined with a Leica LABOPHOT-2 stereomicroscope. Illustrations of the male genitalia were prepared using a NIKON microscope with a drawing tube attachment. Images were taken with a Canon 70D DSLR attached to a Leica Z6 microscope. Individual source images were then stacked using Helicon Focus v. 6.22 software, with calibrated scale bars added using Syncroscopy Automontage v. 5.4. The maps (Figs
