Abstract Because of taxonomic diversity, geographic isolation, and other considerations, subterranean groundwater amphipods would appear to make excellent candidates for biogeographic studies. Limted dispersal ability in combination with local endemism makes it likely that vicariance models will generally offer better explanations for present distribution patterns of subterranean amphipods than scenarios based on centers of origin and dispersal. Vicariance biogeography demands a knowledge of both phylogeny and area relationships, which are typically shown on biological area cladograms. To date most biogeographic studies on subterranean amphipods have been limited to cladograms of single taxonomic groups. Although useful in showing possible relationships between areas and nested subsets of taxa, these single taxon studies do not consider covariant patterns among different groups. However, in order to be fully effective, future biogeographic research will have to focus on analyses of congruence between biological area cladograms of amphipod taxa and other subterranean crustacean groups, such as isopods. To date many covariant distributions among groups of subterranean crustaceans have been recognized but not yet analyzed for congruence.
