Abstract: 　Objective To analyze the taxonomic status of Paragonimus hokuoensis, P.paishuihoensis, P.menglaensis, P.bangkokensis and P.xiangshanensis in Genus Paragonimus Braun, 1899. Methods DNA sequences were obtained from the ITS2 and COⅠ genes and phylogenetic trees were built from these. Results There are some DNA sequence differences among P.paishuihoensis, P.menglaensis, P.bangkokensis and P.xiangshanensis, but the differences are small. P.hokuoensis and P.skrjabini are similar in DNA sequence. Conclusion P.paishuihoensis, P.menglaensis, P.bangkokensis and P.xiangshanensis are closer in the genetic relationship. Their taxonomic status lies between P.skrjabini and P.westermani. The genetic relationship between P.hokuoensis and P.skrjabini is very close.

Key words: Genus Paragonimus, DNA sequence, taxonomy
