Allozyme variability in the androgenetic freshwater clams Corbicula leana from Japan and the exotic C. fluminea were investigated. A total of 462 individuals of C. leana from 19 localities throughout the distribution range of the species were monomorphic at three allozyme loci as well as in purple inner shell color. Corbicula fluminea from three localities, on the other hand, was variable in shell color; with white, purple, white with purple flash, or deep purple examples. The present results suggest that they may include several clonal lines with different shell colors and allozyme genotypes. We discuss possible diversification of freshwater clams among bisexual species and hermaphroditic clones through clonal capture, genome capture, or ploidy elevation.
