Abstract

Okanagana boweni sp. n. is described from the western margin of the Great Basin of North America. The new species is diagnosed from allopatric O. simulata Davis and sympatric O. utahensis Davis using morphological, bioacoustical, and molecular characters. The distribution of this new species coincides with the Walker Lane region that lies along the border of California and Nevada, USA. Based on geography, bioacoustics, morphology, and molecular phylogenetics, we hypothesize that O. boweni sp. n. is the allopatric sister species of O. simulata.
