The genetic structure of the marine flatwormStylochoplana pusilla(Rhabditophora: Polycladida) and its use of intertidal snails

Although marine phylogeographers have accumulated knowledge of the evolutionary history of various invertebrates, there is a large bias among the taxa regarding genetic data. The order Polycladida is a typical example for which little genetic information at population level is available. Here, we focused on the polyclad flatworm Stylochoplana pusilla , distributed in the Japanese Pacific coastal area. Stylochoplana pusilla is known to have...
