The enchytraeid fauna (Enchytraeidae: Clitellata) of the Fanjing Mountain National Nature Reserve (China) with description of two new species

The first ever survey of the enchytraeid fauna in the Fanjing Mountain National Nature Reserve (Guizhou, China) yielded a total of eight species, two of them new to science: Xetadrilus prolixglandus sp. nov. and Hemienchytraeus tenuiculus sp. nov. One unidentified and possibly new species of Fridericia and five additional species, Achaeta brevivasa, Enchytraeus buchholzi, Fridericia loretensis, Henlea perpusilla and Hemienchytraeus stephensoni, are recorded and described, based on the collected material. The species records include morphological descriptions and molecular data (the mitochondrial cytochrome c oxidase subunit 1 (COI) gene, the nuclear ribosomal ITS region and the nuclear histone 3 (H3) gene).
