Among taeniid tapeworms infecting humans through pork or beef, Taenia solium Linnaeus 1758 and Taenia saginata Goeze 1782 have already been known. Based on the morphologic characteristics of adult and metacestodes of Asian Taenia saginata, the third kind of human taeniid tapeworm known to distribute in Asian countries, a new species name of Taenia asiatica is proposed. In addition to the known biology in their intermediate hosts, T. asiatica was different morphologically from Taenia saginata Goeze 1782 in having the unarmed rostellum on the scolex of adult, the large number of 'uterine twigs' and the existence of 'posterior protuberance'. These structures in the gravid proglottids were used as taxonomic keys in taeniid tapeworms for the first time. T. asiatica metacestode (Cysticercus viscerotropica) was different morphologically from T. saginata metacestode (Cysticercus bovis) in having wartlike formations on the external surface of the bladder wall.
在通过猪肉或牛肉感染人类的带绦虫中，1758年的猪带绦虫（Taenia solium Linnaeus）和1782年的牛带绦虫（Taenia saginata Goeze）早已为人所知。基于亚洲牛带绦虫成虫和中绦期的形态特征（这是已知分布于亚洲国家的第三种人体带绦虫），提出了亚洲带绦虫（Taenia asiatica）这一新的物种名称。除了在中间宿主体内已知的生物学特性外，亚洲带绦虫在形态上与1782年的牛带绦虫不同，其成虫头节上无顶突，有大量“子宫分支”以及存在“后突”。妊娠节片中的这些结构首次被用作带绦虫分类的关键特征。亚洲带绦虫中绦期（嗜内脏囊尾蚴，Cysticercus viscerotropica）在形态上与牛带绦虫中绦期（牛囊尾蚴，Cysticercus bovis）不同，其囊壁外表面有疣状结构。
