We compare the phylogeographical structure among caves for co-occurring cave dwelling crickets (Ceuthophilus) in two subgenera Ceuthophilus (Ceuthophilus) (hereafter, called Ceuthophilus) and Ceuthophilus (Geotettix) (hereafter, called Geotettix). In our study area (central Texas), cave-inhabiting members of the subgenus Ceuthophilus are trogloxenes, roosting in the caves but foraging above ground and occasionally moving between caves, whereas members of the subgenus Geotettix are near-obligate cave dwellers, which forage inside the caves, and only rarely are found above ground. Differences in potential dispersal ability and ecology provide a framework for understanding their effects on the phylogeographical structure and isolation of populations of cave dwelling organisms.
