The re-description of Synoecnema hirsutum Timm, 1959 (Synoecneminae, Ungellidae, Drilonematoidea) from a pheretimoid earthworm in Vietnam with the analysis of its phylogenetic relationships

Synoecnema hirsutum Timm, 1959 (Ungellidae, Drilonematoidea), found in the body cavity of the phereti-moid earthworm at the border of Laos and Vietnam, was re-described and illustrated. The mitochondrial genome of S. hirsutum obtained with Illumina HiSeq sequencing is the first annotated mitochondrial genome as a representative of the superfamily Drilonematoidea. The phylogeny inferred from the analysis of 12 mitochondrial genes has shown some similarity of S. hirsutum with a cephalobid Acrobeloides varius.
