摘要： The taxonomic concept for the family Paruterinidae is controversial, especially concerning the position of the genus Cladotaenia, since the latter genus has been placed sometimes in other families, i.e. in the Taeniidae or in the distinct family Cladotaeniidae; finding a solution based on morphological data is difficult and molecular data on paruterinids and related groups are scarce. In this study, the complete mitochondrial (mt) genome sequence of the type-species of the type-genus of the Paruterinidae, Paruterina candelabraria, was determined and annotated. Gene arrangements are identical with those of Cladotaenia vulturi but differing from those of species of the family Taeniidae by the order change between tRNA-SerUCN and tRNA-LeuCUN. Phylogenetic tree was constructed by Bayesian Inference (BI) analysis using the concatenated amino acid sequences of 12 protein-coding genes. The analysis clearly shows that the Paruterinidae and Taeniidae are sister-groups, and Cladotaenia is a sister taxon of Paruterina. This supports the position of the genus Cladotaenia in the family Paruterinidae and reveals the necessity for sequencing additional taxa of the Paruterinidae for better understanding of phylogenetic relationships within the group.
