Review of the Allonemobius fasciatus (Orthoptera: Gryllidae) Complex with the Description of Two New Species Separated by Electrophoresis, Songs, and Morphometrics

Abstract

The Allonemobius fasciatus (De Geer) complex, a group of closely related ground crickets, has proven recalcitrant to analysis by traditional methods of museum taxonomists. Here we formally describe two new species ( A. walkeri and A. fultoni ), reinstate the species status of A. socius (Scudder), and provide an electrophoretic key to the complex. In addition, we describe male calling song, habitat, life cycle, and geographic distribution of each species in the complex, and we compare the species morphometrically.
