Abstract

The present study provides the first confirmed records of Corbicula fluminea and C. leana in Vietnam based on DNA sequence data. Additionally, C. blandiana, an endemic species to the Mekong River basin, was identified. The COI sequences of Corbicula fluminea and C. leana from Vietnam are either identical or differ by one or two nucleotide substitutions from those collected in Japan, China, and Myanmar. These new DNA sequence data support our earlier hypothesis that populations of C. leana and C. fluminea in Southeast and East Asia have served as sources for their worldwide expansion.
