First mitogenome of moniezia sichuanensis from forest musk deer with comparative analyses within cyclophyllidea.

We characterised, for the first time, the whole mitogenome of a unique tapeworm, Moniezia sichuanensis (Cyclophyllidea, Anoplocephalidae) of forest musk deer (Moschus berezovskii). The total length of the circular mitogenome was 13,652 bp. It consisted of 12 protein-coding genes (PCGs), 22 transfer RNA genes, and two ribosomal RNA genes, which are typical of the mitogenomes of Moniezia. By comparing the available mitogenomes of PCGs for Cyclophyllidea in GenBank, nad6 and cox1 showed the highest and lowest evolutionary rates, respectively, and cox2 could be used as a potential DNA barcoding marker. The phylogenetic analyses of Cyclophyllidea confirmed the monophyly of the genus Moniezia and the family Anoplocephalidae; they then formed a clade with species of Hymenolepididae. Moreover, two novel gene arrangements of Cyclophyllidea were observed.
