In order to clarify the taxonomic status of the Taenia saginata-like tapeworm in East Asia, the morphological characteristics of the adult and cysticercus of classical T. saginata (American, Swiss and Poland strains) and the Taiwan Taenia were compared in the present study. The morphologic characteristics of these two parasites are very similar. The protoscolex of cysticercus of the Taiwan Taenia has a sunken rostellum while that of classical T. saginata has only an apical pit. In addition, the rostellum of the Taiwan Taenia cysticercus is usually surrounded by two rows of rudimentary hooklets. However, this structure is rarely found in classical T. saginata. Based on the results of molecular studies and morphological characteristics, the T. saginata-like tapeworm in East Asia represents a subspecies of T. saginata, named T. saginata asiatica.
为阐明东亚牛带绦虫样绦虫的分类地位，本研究比较了经典牛带绦虫（美国、瑞士和波兰株）及台湾带绦虫成虫和囊尾蚴的形态特征。这两种寄生虫的形态特征非常相似。台湾带绦虫囊尾蚴的原头节有一个凹陷的顶突，而经典牛带绦虫只有一个顶端凹陷。此外，台湾带绦虫囊尾蚴的顶突通常被两排小钩雏形所环绕。然而，这种结构在经典牛带绦虫中很少见。基于分子研究结果和形态特征，东亚牛带绦虫样绦虫代表牛带绦虫的一个亚种，命名为亚洲牛带绦虫。
