Scalithrium gen. n. (Cestoda, Tetraphyllidea) is proposed with Scalithrium minimum (Van Beneden, 1850) n. comb., parasite of Dasyatis pastinaca (Elasmobranchii, Dasyatidae) as type-species. The new genus Scalithrium (Tetraphyllidea, Phyllobothriidae, Rhinebothriinae) is erected for several species previously included in the genus Rhinebothrium. These species have a scolex with four bothridia, the distal surface of which is divided by transverse septa in a single row of loculi. Scalithrium minimum (Van Beneden, 1850) n. comb. is redescribed from specimens collected from the type-host Dasyatis pastinaca in Tunisia and becomes the type-species of the new genus. After Braun (1900) Echeneibothrium variabile Van Beneden, 1850 is considered as type-species of the genus Echeneibothrium. Species of Rhinebothriinae to be transferred into the genus Scalithrium are discussed and a key is proposed for the eight species.
提出了新属Scalithrium gen. n.（绦虫纲，四叶目），以微小Scalithrium minimum（范·贝内登，1850年）n. comb.为模式种，它是黄貂鱼Dasyatis pastinaca（板鳃亚纲，黄貂鱼科）的寄生虫。新属Scalithrium（四叶目，叶槽科，Rhinebothriinae亚科）是为以前归入Rhinebothrium属的几个物种而设立的。这些物种的头节有四个吸叶，其远端表面被横向隔膜分隔成单排小室。根据从突尼斯的模式宿主黄貂鱼Dasyatis pastinaca采集的标本对微小Scalithrium minimum（范·贝内登，1850年）n. comb.进行了重新描述，并成为新属的模式种。自布劳恩（1900年）之后，1850年的可变艾氏叶槽绦虫Echeneibothrium variabile被视为艾氏叶槽绦虫属的模式种。讨论了拟转入Scalithrium属的Rhinebothriinae亚科的物种，并为这八个物种提出了一个检索表。
