Five species of Dolichopoda cave crickets have been studied by means of mtDNA RFLPs. The phylogenetic relationships among them were previously inferred from two different molecular measures: allozyme polymorphisms and DNA-DNA hybridization. mtDNA data generate a phylogeny exactly matching those obtained from the other two genetic markers. This is not always the case for other organisms studied so far. This result is discussed in respect of the performance of the three molecular approaches and the population biology of these cave dwelling insects. A tentative calibration of mtDNA rate for Dolichopoda produces an estimate of about 2%/lineage/Myr. The comparison between mtDNA and scnDNA divergence estimates suggests that in these crickets changes accumulate approximately 2-3 times faster in mitochondrial than single copy nuclear sequences. © 1993 Academic Press.
