摘　　要：Several specimens of the giant deep-sea isopod genus Bathynomus were collected by a deep-sea lander at a depth of 898 m near Hainan Island in the northern South China Sea.After careful examination,this material and the specimens collected from the Gulf of Aden,north-western Indian Ocean,previously reported as Bathynomus sp.,were identified to be the same as a new species to the genus.Bathynomus jamesi sp.nov.can be distinguished from the congeners by:the distal margin of pleotelson with 11 or 13 short straight spines and central spine not bifid;uropodal endopod and exopod with distolateral corner slightly pronounced;clypeus with lateral margins concave;and antennal flagellum extending when extended posteriorly reaches the pereonite 3.In addition,Bathynomus jamesi sp.nov.is also supported by molecular analyses based on mitochondrial COI and 16S rRNA gene sequences.The distribution range of the new species includes the western Pacific and north-western Indian Ocean.
