A new species of Nearctopsylla Rothschild 1915 (Siphonaptera: Hystrichopsyllidae) from the southern Appalachians.

Nearcyopsylla pfitzeri sp. n. is a parasite of the short-tailed shrew, Blarina brevicauda, in the Great Smoky Mountains. Only two females have been collected, but they are clearly distinct from both the more northern N. genalis and the more southern N. georgiana.
