摘      要：Sequences of the first internal transcribed spacer(ITS-1)and the D1-D3 domains of the largesubunit(LSU)of the ribosomal DNA(rDNA)were determined for multiple specimens of fouroperational taxonomic units(OTUs)of the monogenean,Pseudorhabdosynchous *** defined based on their collecting localities,host and/or morphological *** *** specimens of one group(OTUs 1 and 3)differed in their sequences of the ITS-1 and partialLSU rDNA when compared with specimens of a second group(OTUs 2 and 4)by 12% and 2%,*** of the phylogenetic analyses of the LSU rDNA sequence data showed total(100%)bootstrap support for the separation of *** into two distinct *** least 11 of the 18nucleotide differences in the LSU sequence between the two *** elades were derived(***)characters when the morphologically distinct species,*** and ***,were used as ***,there were several ftxed autapomorphic character states for each *** *** provides sufficient evidence to reject the null hypothesis that *** a single *** and morphometric differences between these two cladesprovided additional strong support for the separation of *** into two *** twoparasite species were found to co-exist in one of the two species of serranid fish(***)examined in the South China Sea(Guangdong Province,China).
