摘　　要：We present a molecular assessment of the widely-distributed ricefrog(Fejervarya limnocharis)which provides many newsamples that add to knowledge of their phylogeography within China and considersgenetic support forfive Chinese species withinthis complex.TwomtDNAfragments from 270 individuals and eight nuclearDNAloci(105 individuals)were sequenced from specimens sampled from across China.Data from nine specimens from China,Indonesia and Japan were also retrieved from previous studies.MtDNAwas informativeabout population divergence within China and indicated one major clade(with four subclades)from South China and the Zhoushan Archipelago,Zhejiang,China,and a second major clade(with eight subclades)from other parts of China.Recent demographic expansions(less than 50ka ago)were detected within three of these 12 subclades,potentially associa ted with lowered sea-levels after marine transgressions.Nota bly,most frogs from the previously unstudied Zhoushan Archipelago(eastern China)were found to be closely related to Japanese populations.BPPand STACEY species delimitation analyses of the multilocus data favoured five candidate species within the complex.Previous work had described Fejervaryamultistriata and F.kawamurai from the Chinese mainland although here we detected considerable genetic divergence within the latter and found that this may be indicative of two species.One of these corresponds to the Zhoushan Archipelago,Zhejiang,China and Japan,and the other from most parts of Chinese mainland.This study provides a large multilocus dataset that contributes to the systematics of this species complex.
