One new genus, Paramphimonhystrella gen. nov., and three new species of free-living marine
nematodes in this genus, P. elegans sp. nov., P. minor sp. nov., and P. sinica sp. nov., are described and
illustrated from the Yellow Sea, China. Paramphimonhystrella gen. nov. differs from the similar genus
Amphimonhystrella by the elongated buccal cavity, cervical setae and large caudal glands.
Paramphimonhystrella elegans sp. nov. is characterized by ovoid amphids and spicules with a small
hook at distal end and cylindrical part of tail shorter than conical part. Paramphimonhystrella sinica sp.
nov. is characterized by circular amphids, wide buccal cavity, spicules with blunt tip, and cylindrical
part of tail longer than conical part. Paramphimonhystrella minor sp. nov. differs from the other two
species by its smaller body (shorter than 800 mm), circular amphids, and spicules with sharp tip. The
type species of this new genus is P. elegans gen. nov. and sp. nov. Types are deposited in the College of
Marine Life Sciences, Ocean University of China.
