重新检查美国国家蜱收集中心的台湾革蜱杉本，1935标本，发现两种形态上不同的革蜱属物种在这个名称下被鉴定。其中之一与Sugimoto对D.台湾革蜱（Dermacentorbellulus，Schulze，1935）。后一种被最近的工作者认为是无效的。D. bellulus在这里被恢复为一个有效的种，它的所有阶段都被重新描述。D.并首次描述其未成熟期。D. bellulus与D.根据生殖器的形态、颜色、生殖器的结构、触须和角的大小以及基节I的距等特征，对台湾种与台湾种进行了比较。D. bellulus与D.根据盾板、头状基和口下齿列的形状，将其与taiwanensis区分开来。拉尔丹D. bellulus与D. taiwanensis的形态特征，以及耳突和第III节距腹侧的发育程度。D.在中国、日本、尼泊尔、台湾和越南都有记录;从野猪、熊、熊猫、狗和人身上收集到成虫;从啮齿动物、野兔、鼬獾和竹子身上发现了未成熟的阶段。D. taiwanensis在中国、台湾和越南都有发现;成年个体是从野猪身上采集的;未成熟的阶段是从啮齿动物、野兔、鼬科动物和家犬身上发现的。
Re-examination of Dermacentor taiwanensis Sugimoto, 1935 specimens in the United States National Tick Collection revealed that two morphologically distinct Dermacentor species were identified under this name. One of them corresponds to Sugimoto's description of D. taiwanensis, while another species is identical to Schulze's Dermacentor bellulus (Schulze, 1935). The latter species has not been considered valid by recent workers. D. bellulus is reinstated here as a valid species and all its stages are redescribed. The adults of D. taiwanensis are also redescribed, and its immature stages are described for the first time. Males and females of D. bellulus can be distinguished from those of D. taiwanensis by the shape of the conscutum and scutum, color pattern, genital structures, size of the palpi and cornua, and the spurs of coxa I. Nymphs of D. bellulus can be distinguished from those of D. taiwanensis by the shape of the scutum, basis capituli, and the hypostomal dentition. Larvae of D. bellulus can be differentiated from those of D. taiwanensis by the shape of the basis capituli, and the degree of development of the auriculae and spur on palpal segment III ventrally. D. bellulus has been recorded from China, Japan, Nepal, Taiwan, and Vietnam; adults have been collected from wild boars, bears, panda, dog, and human; the immature stages are known from rodents, hares, ferret-badger, and bamboo-partridge. D. taiwanensis is found in China, Taiwan, and Vietnam; adults have been collected from wild boars; the immature stages are known from rodents, hares, mustelids, and domestic dog.
