According to the latest taxonomy of Spirometra species, six species (lineages) have been tentatively classified as valid. These species are Spirometra erinaceieuropaei, S. folium, S. mansoni, undescribed Spirometra sp. 1, and S. decipiens complex 1 and 2. Among these species, the undescribed species was first discovered as plerocercoid larvae in wild boars in Japan and further studies have confirmed that this species is a new taxon belonging to the genus Spirometra. Here, we describe Spirometra asiana sp. nov., which is difficult to distinguish morphologically from known Spirometra species. However, it is genetically easily distinct from other Spirometra species, thus facilitating identification. We also emphasize that S. mansoni and S. asiana, but not S. erinaceieuropaei, are etiological agents that cause human sparganosis and/or spirometrosis in Asia.
根据裂头绦虫属物种的最新分类法，六个物种（谱系）已被暂定分类为有效物种。这些物种是猬迭宫绦虫、孟氏裂头绦虫、曼氏迭宫绦虫、未描述的裂头绦虫属物种1，以及迷惑迭宫绦虫复合体1和2。在这些物种中，未描述的物种最初是在日本野猪体内作为裂头蚴幼虫被发现的，进一步研究证实该物种是属于裂头绦虫属的一个新分类单元。在此，我们描述了亚洲裂头绦虫新种，它在形态上难以与已知的裂头绦虫属物种区分开来。然而，在基因上它很容易与其他裂头绦虫属物种区分，从而便于鉴定。我们还强调，曼氏迭宫绦虫和亚洲裂头绦虫，而非猬迭宫绦虫，是在亚洲导致人体裂头蚴病和/或裂头绦虫病的病原体。
