Allozymic variation in proteins encoded by 14 loci was analyzed in 3 cavernicolousMonolistra and in 2 marineSphaeroma species. Genetic distance data, high levels of heterozygosity and the divergence time calculations support the hypothesis thatMonolistra diverged from its Sphaeroma-like marine ancestor during the Messinian, in connection with the Mediterranean salinity critis.
