A new species of the genus Metaphire (Oligochaeta, Megascolecidae) from northern China with data from the mitochondrial genome

This dataset contains the digitized treatments in Plazi based on the original journal article Liu, Qingyu, Zhao, Huifeng, Aspe, Nonillon M., Zhang, Yufeng, Zhang, Wenqi, Zhang, Zhenjiang, Dong, Yanjie (2026): A new species of the genus Metaphire (Oligochaeta, Megascolecidae) from northern China with data from the mitochondrial genome. ZooKeys 1278: 53-71, DOI: 10.3897/zookeys.1278.182854AbstractThis study describes a new species, Metaphire wenanensis Liu & Zhao, sp. nov. integrating morphological characters and molecular data. The new species is assigned to the M. houlleti group, and is characterized by three pairs of spermathecal pores at 6 / 7–8 / 9, and absence of genital markings both anterior and posterior to the clitellum. The spermathecae are connected to the body wall through a disc-shaped atrium, which is interposed between them and the body wall. The molecular phylogenetic position of M. wenanensis Liu & Zhao, sp. nov. within the M. houlleti group was analyzed using mitochondrial genome data. This marks the initial documentation of a new species within the family Megascolecidae in northern China since the last decades.
