Based on previous molecular phylogenetic analyses, Bothriocestus n. gen. is erected to accommodate bothriocephalid tapeworms that have an elongate scolex, a well-developed apical disc, and a narrow neck region, parasitize freshwater fishes in the Holarctic, and were previously placed in the polyphyletic genus Bothriocephalus Rudolphi, 1808 (Cestoda: Bothriocephalidea). Bothriocestus claviceps (Goeze, 1782) n. comb., a parasite of eels (Anguilla spp.) in the Holarctic region, is designated as the type species. Another species of the new genus, Bothriocestus cuspidatus (Cooper, 1917) (syn. Bothriocephalus cuspidatusCooper, 1917) is redescribed from type and voucher specimens, and new material from the type host, the walleye, Sander vitreus (Mitchill, 1818) (Perciformes: Percidae), in Manitoba and Ontario (where the type locality is located) (Canada) and in New York state and Wisconsin. Bothriocestus cuspidatus of S. vitreus is characterized primarily by the possession of a narrow, long strobila (total length up to 18 cm) composed of distinctly craspedote, trapezoidal proglottids, with primary, secondary, and tertiary proglottids differing in size, and by an arrow-shaped (=cuspidatus) scolex that is distinctly broader than the first proglottids, widest near the base in lateral view and gradually becoming broader toward the anterior end in dorsoventral view. A “dwarf” form of B. cuspidatus (total length of 9–27 mm) from Johnny darter, Etheostoma nigrum Rafinesque, 1820, and tessellated darter, Etheostoma olmstedi Storer, 1842 (both Percidae: Etheostominae), is also characterized morphologically in the present paper.

根据之前的分子系统发育分析，Bothriocestus n。将军 是为了容纳双头动物绦虫而建立的，这种绦虫具有细长的头节、发育良好的顶盘和狭窄的颈部区域，寄生在全北区的淡水鱼中，并且之前被归入多系Bothriocephalus Rudolphi属，1808年（Cestoda：Bothriocephalidea）。Bothriocestus claviceps (Goeze, 1782) n. 梳状鳗鱼（Anguilla spp.）是全北区鳗鱼（Anguilla spp.）的一种寄生虫，被指定为模式种。新属的另一个物种，Bothriocetusus cuspidatus (Cooper, 1917)（同义词。Bothriocephalus cuspidatus Cooper, 1917）根据模式和凭证标本进行了重新描述，新材料来自模式寄主，白眼斑眼鱼，Sander vitreus（Mitchill, 1818）（鲈形目：鲈科），分布于马尼托巴省和安大略省（模式产地所在）（加拿大）以及纽约州和威斯康星州。玻璃体的Bothriocestus cuspidatus的主要特征是具有狭窄、长的节片（总长可达18厘米），由明显的钩状、梯形节片组成，初级、次级和第三级节片大小不同，并有一个箭头形（= cuspidatus）头节明显比第一节片宽，在侧视图中靠近基部最宽，并且在背腹视图中朝前端逐渐变宽。来自约翰尼鲈鱼Etheostoma nigrum Rafinesque, 1820 和棋盘状鲈鱼Etheostoma olmstedi Storer, 1842（均为鲈科：Etheostominae）的“矮化”形态的B. cuspidatus（总长 9-27 毫米）在形态学上也有特征目前的论文。
