Polyplax auricularis Kellogg & Ferris

Ex Peromyscus maniculatus (deer mouse): 1N, NC, Haywood Co., Purchase Knob, 20 Oct. 2002, K. Walters, L­3047; 1F, TN, Sevier Co., Walker Prong, 15 Jun. 1953, R. Traub & D. Pfitzer (Durden et al. 1997a); 1M, TN, Sevier Co., Brushy Mount, 7 Apr. 2002, K. Walters, L­3006.

This louse is a widespread ectoparasite of sigmodontine rodents (some species of Onychomys, Peromyscus and Reithrodontomys) in North and Central America (Durden & Musser 1994). Polyplax auricularis appears to be more common in northern latitudes or at higher elevations in southern latitudes.
