SSAR 9th Edition Comments:
Gottscho (2015, Ph.D. dissertation, University of California at Riverside and San Diego State University), based on RADseq data, found that P. mearnsi samples were divided into northern and southern clades and populations, with P. slevini included within the southern population and sister to the remaining members of that population.

Range maps are based on curated specimens and provided gratis by CNAH.
