| Abstract |
A new species of free-living marine nematode of the genus Paramonohystera was described from the intertidal beach, Weihai. Paramonohystera weihaiensis sp. nov. is characterized by cervical region with a circle of long setae; tail sexual dimorphism, male tail angled dorsally with sharp narrowed of the body at the cloaca, female tail ordinary conico-cylindrical; spicules slender, 2.5 abd long; gubernaculum plate, enlarged distal end with two teeth, without apophysis; precloacal supplements absent; Four caudal gland cells obviously extended to tail. The new species diff ers from the other fourteen known valid congeners by the combination of its characteristics: a circle of long cervical setae, tail sexual dimorphism, spicules slender, 2.5 abd long, gubernaculum plate with a distal pair of teeth. |
