Mosla hangchouensis (MH) and M. japonica (MJ) are endangered species. The former is endemic to China, and the latter is endemic to Japan. The two countries share a closely related and widely distributed species, M. chinensis (MC). The genetic diversity of these three species evaluated using RAPD markers is very low. The average percentages of polymorphic bands were 4.0%, 6.3% and 7.8% for MC, MH and MJ respectively at population level. At species level, the percentages of polymorphic bands were 31.1% and 57.1% respectively for MC and MH. The molecular variance among populations accounted 86% for MC, and 74% for MH. Neighbor-Joining tree showed that MJ was intermediate between MC and MH.
