title: Phylogenetic analysis within Monhysteridae and Thoracostomopsidae based on rDNA sequences and two new species from the Yellow Sea, China
abstract: Phylogenetic relationships based on rDNA in nematodes are complex and remain understudied. During our taxonomic study on Changdao Island, three species— Thalassomonhystera tortospicula sp. nov. , Enoploides parakoreanus sp. nov. , and Enoplolaimus lenunculus Wieser, 1959—are described. Thalassomonhystera tortospicula sp. nov. is characterized by a medium-sized body, short outer labial and cephalic setae, amphidial fovea positioned at the buccal cavity, twisted spicules, gubernaculum with a dorso
