Abstract

Two new species of free-living marine nematodes Paramarylynnia filicaudata sp. nov. and Paramarylynnia stenocervica sp. nov. from the Yellow Sea, China are described. Paramarylynnia filicaudata sp. nov. is characterized by a homogeneous cuticle with transverse rows of even dots; spicules boat-shaped, swollen in the middle and gradually tapering towards both ends; tail conical with a long filiform terminal portion and without subventral setae on the conical part. Paramarylynnia stenocervica sp. nov. is characterized by the marked narrower anterior part of the neck region; heterogeneous cuticle with transverse rows of punctations and the punctations of anterior contracted portion larger and more widely spaced than the remaining portion; spicules curved and cephalate proximally; gubernaculum boat-shaped, swollen in the middle and gradually tapering towards both ends, five small tubular precloacal supplements.
