Anthobothrium laciniatum Linton, 1890 is redescribed based on specimens taken from the dusky shark Carcharhinus obscurus (Lesueur) collected from the Northwestern Atlantic Ocean, and a neotype is designated. A. laciniatum differs from A. cornucopia van Beneden, 1850, A. altavelae Euzet & Ben Hassine, 2002, A. lesteri Williams, Burt & Caira, 2004 and A. spinosum Subhapradha, 1955 in total length. It further differs from A. cornucopia, A. altavelae and A. spinosum in proglottid number, and differs from A. galeorhini Suriano, 2002, A. cornucopia, and A. spinosum in testis number. A. lyndoni n. sp. is described from the sandbar shark C. plumbeus (Nardo). This new species differs from A. laciniatum in ovarian width and from A. cornucopia, A. altavelae, A. galeorhini and A. spinosum in the total number of proglottids. It further differs from A. cornucopia, A. galeorhini, and A. spinosum in total length, and from A. cornucopia and A. galeorhini in the number of testes. A. lyndoni n. sp. differs from A. lesteri in bothridial muscle and ovarian morphology. Anthobothrium caseyi n. sp. is described from Prionace glauca (Linnaeus). This new species differs conspicuously from the other six species of Anthobothrium van Beneden, 1850 (sensu stricto) in the shape of its proglottid laciniations. The taxonomic status of 43 species that have been associated with Anthobothrium is addressed. Taxonomic actions regarding Anthobothrium during the past century have resulted in a polyphyletic taxon.
基于从西北大西洋捕获的暗体真鲨（Carcharhinus obscurus，莱叙厄尔）采集的标本，对1890年命名的有叶花槽绦虫（Anthobothrium laciniatum 林顿）进行了重新描述，并指定了一个新模标本。有叶花槽绦虫在体长方面与1850年命名的角花槽绦虫（A. cornucopia 范·贝内登）、2002年命名的高帆花槽绦虫（A. altavelae 厄泽特和本·哈西内）、2004年命名的莱斯特花槽绦虫（A. lesteri 威廉姆斯、伯特和凯拉）以及1955年命名的棘花槽绦虫（A. spinosum 苏布哈普拉达）不同。它在节片数量上与角花槽绦虫、高帆花槽绦虫和棘花槽绦虫进一步不同，在睾丸数量上与2002年命名的鼬鲨花槽绦虫（A. galeorhini 苏里亚诺）、角花槽绦虫和棘花槽绦虫不同。新种林登花槽绦虫（A. lyndoni n. sp.）是从铅灰真鲨（C. plumbeus，纳尔多）中描述的。这个新物种在卵巢宽度上与有叶花槽绦虫不同，在节片总数上与角花槽绦虫、高帆花槽绦虫、鼬鲨花槽绦虫和棘花槽绦虫不同。它在体长上与角花槽绦虫、鼬鲨花槽绦虫和棘花槽绦虫进一步不同，在睾丸数量上与角花槽绦虫和鼬鲨花槽绦虫不同。林登花槽绦虫在吸槽肌和卵巢形态上与莱斯特花槽绦虫不同。新种凯西花槽绦虫（A. caseyi n. sp.）是从灰鲭鲨（Prionace glauca，林奈）中描述的。这个新物种在节片裂片形状上与1850年命名的花槽绦虫属（Anthobothrium 范·贝内登，狭义）的其他六个物种明显不同。讨论了与花槽绦虫相关的43个物种的分类地位。过去一个世纪里关于花槽绦虫的分类学行为导致了一个多系分类单元。
