The Ryukyu Robin species complex, including the Larvivora komadori and Okinawa L. namiyei, is endemic to islands of Archipelago. Population genetic structure gene flow within this complex were investigated using 14 nuclear microsatellite markers. Distinct differentiation was detected between robins, further differentiated into four regional groups belonging Danjo Islands, Tokara Oh-shima with some adjacent islands, Tokuno-shima. Contemporary among these restricted overall, but outflow from Islands group other three exceptionally high. This asymmetric pattern may have been affected by differences in isolation distance, migratory habits, population size. long considered a single polytypic species; however, it has recently classified as two independent species, mainly owing deep mitochondrial DNA divergence them phenotypical re-examination. inferred loci strongly supports their independence. provides first case birds for which splitting sister both Archipelago supported all morphological, behavioral, ecological, evidence. Such recognition appears preferable avian conservation biogeography studies. Currently, includes an Endemic Bird Area Natural World Heritage sites, making reliable delimitation more important. Comprehensive investigation, together re-examination necessary, even closely resembling allopatric forms region.
