线粒体COI基因的一部分的DNA序列被用来澄清日本种Cercopithifilaria属之间的系统发育关系。对日本7个种的C. shohoi、C. multicauda、C. minuta、C. tumidicervicata和C. bulboidea），从长绒山羊（Capricornis crispus F. Bovidae）和梅花鹿Cervus nippon nippon F.鹿科）。球根拟步行虫与C. longa，这表明最近的主机转换之间的牛科动物和鹿科动物的主机C bulboidea谱系引起C longa。在系统发育树推断使用各种方法，形态上的祖先型，C bulboidea，出现作为一个衍生种。分析中发现多尾C是基础的。因此，看来C multicauda是七个物种中最原始的。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
DNA sequences from a portion of the mitochondrial COI gene were used to clarify phylogenetic relationships among Japanese species in the genus Cercopithifilaria. Sequences were determined from seven Japanese species, five (C shohoi, C multicauda, C minuta, C tumidicervicata and C. bulboidea) from the serow (Capricornis crispus F. Bovidae) and two (C longa and C crassa) from the sika deer (Cervus nippon nippon F. Cervidae). No base substitutions were observed between C bulboidea and C. longa, suggesting that recent host switching of a lineage of C bulboidea between bovid and cervid hosts gave rise to C longa. In phylogenetic trees inferred using a variety of methods, the morphologically ancestral type, C bulboidea, appeared as a derived species. C multicauda was found to be basal in the analyses. It seems therefore that C multicauda is the most primitive out of the seven species. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
