摘　　要：厦门颈褶吸虫 ,新种Tergestiaxiamenensissp .nov .发现于鲈鱼Lateolabraxjaponicus靠近肛门处的肠道 .它与本属较相似的种有尖颈褶吸虫T .acutaManter,1 947和Manter ( 1 947)所报道的T .pectinata (Linton ,1 90 5) .与尖颈褶吸虫相似的地方在于它们都具有 1 4枚围口叶 ,但后者虫体尾部较窄、子宫伸入到睾丸与体末端之间、虫卵较小 ( 0 .0 1 7～ 0 .0 1 9× 0 .0 0 9～ 0 .0 1 0 ) ;与T .pectinata的相似点在于子宫都不进入睾丸与体末端的空间 ,但后者的围口叶为 1 3枚 .The paper deals with a new species of Tergestia Stossich, 1899 (Digenea: Fellodistomidae)obtained from the intestine of Lateolabrax japonicus (Cuvier et Valenciennes).
