| Abstract: | Wakubitinema n. gen. (Nematoda: Seuratoidea: Quimperiidae: Quimperiinae) is erected for Wakubitinema toyamai n. sp. from the small intestine of Rana (Limnonectes) namiyei Stejneger, 1901, on Okinawa Island, Japan. Wakubitinema resembles Paraquimperia Baylis, 1934, and Desmognathinema Baker et al., 1987, but is readily distinguished from the former genus by the distinctly divided esophagus and the absence of cervical flanges and lateral alae, and from the latter genus by the postesophageal position of the excretory pore and cervical papillae and the presence of preanal unpaired papilla in males. Close morphological similarities between Wakubitinema and Paraquimperia may suggest that Wakubitinema has evolved from a quimperiid fish. |
