Based on morphological and molecular data, a new species of tapeworm, Bothriocephalus kupermani n. sp., is described from pumpkinseed, Lepomis gibbosus (Linnaeus, 1758) (type host), and green sunfish, L. cyanellus Rafinesque, 1819 (Actinopterygii: Centrarchidae) in the United States. The new species differs from its North American congeners mainly in the shape of its scolex, which is almost rectangular in dorsoventral and lateral views (nearly parallel margins in the bothrial region), with shallow, wide bothria, and by an extensive field of vitelline follicles that are also variably present, albeit more sparsely, medially in the cortex of the ovarian and uterine areas. This tapeworm appears to be typically associated with Lepomis sunfishes. Examination of museum specimens of Bothriocephalus species from Lepomis spp. indicates that the tapeworm also parasitizes bluegill, Lepomis macrochirus, longear sunfish, Lepomis megalotis, and that previous records of Bothriocephalus cuspidatus and Bothriocephalus claviceps in these fishes are of the new species, B. kupermani.
基于形态学和分子数据，本文描述了一种新的阔节裂头绦虫，即库珀曼阔节裂头绦虫，该虫寄生在美国的南瓜子鲈（林奈，1758）（模式宿主）和绿太阳鱼（拉芬斯奎氏太阳鱼，1819）（硬骨鱼纲：太阳鱼科）中。新种与北美的同属种主要在头节的形状上有所不同，其头节在背腹和侧视图中几乎呈矩形（在两囊区边缘几乎平行），两囊浅而宽，卵黄滤泡广泛存在，在卵巢和子宫区域的皮质中也存在，但在中央部位较为稀疏。这种绦虫似乎通常与太阳鱼属的鱼类有关。对来自太阳鱼属的阔节裂头绦虫物种的博物馆标本的检查表明，该绦虫还寄生在蓝鳃太阳鱼、大口黑鲈、长耳太阳鱼中，以前在这些鱼类中记录的尖吻裂头绦虫和双腔裂头绦虫实际上都是新种，即库珀曼阔节裂头绦虫。
