DNA analysis of a non-native lineage of Sinanodonta woodiana species complex (Bivalvia: Unionidae) from Middle Asia supports the Chinese origin of the European invaders.

The Sinanodonta woodiana species complex includes several cryptic species-level phylogenetic lineages, the taxonomic placement of which is unclear. Here, we present the results of molecular analyses of a Sinanodonta sample from Middle Asia (Uzbekistan). The COI haplotype of the Uzbekistan lineage is similar to those of invasive Sinanodonta populations from Europe, Russia and Myanmar.
