Cave crickets and cave weta (orthoptera, rhaphidophoridae) from the southern end of the world: a molecular phylogeny test of biogeographical hypotheses
Abstract In this study we reconstructed the molecular phylogeny and attempted to infer historical biogeography of a sample of cricket species, most of them cave-dwelling, belonging to the subfamily Macropathinae (Orthoptera, Rhaphidophoridae) which shows a clear Gondwanan distribution. We sequenced...
