| Abstract: |
| A new species of free-living nematode, Pseudolella major sp. nov. is described from the intertidal mudfl ats of Ximen Island in the East China Sea. Pseudolella major sp. nov. is characterized as follows:body length~1300μm; short cephalic setae, 2-3μm long; amphidial fovea loop-shaped with elongated ventral branch; ventral branch 50-60μm long and extending past the base of buccal cavity; buccal cavity cylindrical with arching or spherical base; three heavy outwardly-curving odontia with blunt tips located at anterior of buccal cavity; pharynx short with posterior bulb; ventral gland cell elongate oval-shaped, located posterior to pharyngo-intestinal junction; excretory pore situated at the level of the middle of buccal cavity; tail conical to cylindrical; spicules arched, with double-cephalate proximal end; gubernaculum with a strong dorsal caudal apophysis. |
