摘      要：A new Sillago species,Sillago parasihama sp.n.,is identified based on 127 specimens collected from the southern coast of *** compared the morphological characters between Sillago parasihama and all other 11 Sillago species with two posterior extensions on the swim *** new species is like *** in the countable characters and color pattern,but is different from the latter by the distinct swim *** swim bladder of *** is without lateral *** posterior sub-extensions of anterolateral extensions are unique with some dendritic or sometimes stunted blind tubule,which are unilateral and outward,ex-tending along the abdominal,and are about one-third to half of the body of swim bladder in *** the swim bladder of ***-hama with 8-10 lateral processes,the posterior sub-extensions of anterolateral extensions are kinky,long and complicated,extend-ing along the abdominal wall below the peritoneum to the base of posterior *** can be distinguished from other species in this group by color pattern,meristic,and morphometric ***,the results of genetic analysis using sequences of the mitochondrial cytochrome c oxidase subunit I(COI)fragment show significant interspecific-level genetic distances(0.159-0.231)between *** and 8 congeners in the group,which also support the validity of new *** also provide a distribution map and a key of the related species.
