A new free-living marine nematode species from marine sediments in the East China Sea, is described here as Perspiria boucheri sp. nov. The new species is characterized by amphideal fovea surrounded partially by body annulations; four cephalic setae stout; conical buccal cavity with a minute dorsal tooth and two ventrosublateral teeth; pharynx with a pyriform terminal bulb; tail elongated, conical with 3/4 posterior cylindrical portion which having distinct coarse annulations; spicules strongly curved with narrow ventral velum, handle-shaped proximally; gubernaculum canoe-shaped, without apophysis. The new species differs from the most similar species Perspiria striaticaudata (Timm, 1962) by strongly curved spicules with handle-shaped proximal end, gubernaculum without dorsal apophysis and relatively shorter tail. Updated key to all species of Perspiria is provided.

Two New Species

Two new free-living marine nematode species of the genus Paracomesoma and genus Metacomesoma belonging to family Comesomatidae are described from the sublittoral sediment of the East China Sea. Paracomesoma zhangi sp. nov. is characterized by cuticle with fine transverse rows of dots, without lateral differentiation; buccal cavity with three small teeth; cephalic setae 13.5 μm long; multispiral amphideal fovea with three turns; spicules slender and elongated with thick cuticularized proximal end; gubernaculum plate-like without apophysis; 26 minute precloacal supplements. Metacomesoma macramphida sp. nov. is characterized by very small buccal cavity without teeth; inner and outer labial sensilla papilliform; four cephalic setae 1.5 μm long; multispiral amphideal fovea large, with 4.5 turns; spicules slender and elongated, with cephalated proximal end and finger-shaped distal end; gubernaculum plate-like, without apophysis; precloacal supplements absent. An updated dichotomous key for the identification of the males of the species of Paracomesoma is provided.

Emended Diagnosis

Two new species of free-living nematodes discovered from the sediments in the East China Sea are described: Linhystera breviapophysis sp. nov. and L. longiapophysis sp. nov. Both species possess a dorso-caudally directed gubernacular apophysis, which makes them distinctly different from the two already known species of Linhystera. Linhystera breviapophysis is characterized by a gubernacular apophysis about 3.3 μm long, the presence of a crown of cervical setae and a filiform tail. Linhystera longiapophysis is characterized by a prominent gubernacular apophysis about 10 μm long, sparse cervical setae and a long filiform tail. An emended diagnosis of Linhystera and a pictorial dichotomous key to the species are given.

A New Species

Both sexes of a new species, Stylicletodes wellsi sp. nov. (Harpacticoida: Cletodidae), are described from material collected from sediments in the East China Sea. The new species belongs to a species group whose members are characterized by an anal operculum that has a backwardly directed, median linguiform process and fifth legs that display naked or sparsely pinnate armature elements in both sexes. Within this group, S. wellsi sp. nov. is morphologically closest to S. reductus Wells, 1965 but differs primarily from its European congener in the armature pattern of P4 (both rami) and the female P5. Distribution records of all species are summarized and an updated identification key to the seven valid species in the genus is presented. Taxonomic issues related to the type species S. longicaudatus (Brady, 1880) are briefly discussed.
