Three new species of free-living marine nematodes: Oncholaimus multisetosus sp. nov., Sabatieria stenocephalus sp. nov. and Setosabatieria coomansi sp. nov. from the Yellow Sea, China are described and illustrated. The male of Oncholaimus multisetosus sp. nov. is characterized by a tail sharply constricted at the junction of the conical and cylindrical sections; two circles of 12–15 pairs of circumcloacal setae each. In the female, the conical section of the tail gradually tapers in a cylindrical section. Sabatieria stenocephalus sp. nov. is characterized by the pronounced sharp-pointed anterior body, sclerotized tooth-like front edge of buccal cavity and 15 tubular-shaped precloacal supplements with the posterior five more closely spaced. Setosabatieriacoomansi sp. nov. can be separated from the other species of the genus by the number (6–8) of cervical setae per file, the number of precloacal supplements (15) and the absence of central strips in spicules and leaf-like extensions of the cuticle lateral to the cloaca. Types are deposited in the College of Marine Life Sciences, Ocean University of China.

Three New Species

Three new species of free-living marine nematodes Micoletzkyia longispicula sp. nov., Micoletzkyia filicaudata sp. nov. and Micoletzkyia nanhaiensis sp. nov. from the Yellow Sea and the South China Sea are described. Micoletzkyia longispicula sp. nov. is characterized by spicules elongated and straight, 7 a.b.d. long, pear-shaped proximally and pointed distally; gubernaculum conical, without apophysis, and tubular supplement headlike proximally. Micoletzkyia filicaudata sp. nov. is characterized by slender body with relatively long filiform tail (8.1 a.b.d.), spicules elongated and straight (4.4 a.b.d.), cephalate proximally and pointed distally, gubernaculum tubular, with dorsal apophysis. Micoletzkyia nanhaiensis sp. nov. is characterized by spicules slender and curved, 2.5 a.b.d. long, cephalous proximally and chapiter-shaped distally, and gubernaculum with relatively long dorsal apophysis. A key for all known species of Micoletzkyia is proposed.

Two New Species

Two new species of free-living marine nematodes of the genus Elzalia, Elzalia gerlachi sp. nov. and Elzalia striatitenuis sp. nov. from the Yellow Sea, China, are described and illustrated. Elzalia gerlachi sp. nov. is characterized by relatively large body length (1540–1740 μm in males; 1510–1780 μm in females), spicules 135–160 μm (3.33–3.90 anal body diameter) and complex gubernaculum. Elzalia striatitenuis sp. nov. is characterized by rather small body size (560–660 μm in males; 570–630 μm in females), short cephalic setae 2.5 μm long (21.4–31.3% of head diameter), spicules 65–85 μm (4.06–4.67 anal body diameter) and relatively simple gubernaculum. The two new species can be distinguished from other species of the genus by length and structure of spicules and gubernaculum. Pictorial and tabular keys to the genus are given.

The family Enchelidiidae is recovered as monophyletic and appears to be a more recently derived taxon within the superfamily Oncholaimoidea. It combines nematodes with buccal cavity with three unequal teeth, crenate pharynx, and absence of demanian system. Genus Thoonchus was erected for nematodes characterized by the large buccal cavity with heavily cuticularized walls and several rows of denticles, short and arcuate spicules and gubernaculums with expanded corpus. One new species is described here from the Sishili Bay, located in the northern Yellow Sea. Thoonchus covidus sp. nov. is characterized by the body length 3195‒4339 µm, outer labial and cephalic setae in one circle, pocket shaped amphid above the buccal cavity base, secretory-excretory pore at the base of cephalic setae, arched spicules, gubernaculum with thin proximal extension parallel to spicules, preanal supplement absent, three pairs of preanal papillae. It differs from other congeners by the position of secretory-excretory pore, absence of supplementary organ in males and presence of three pairs of precloacal papillae. Redescription of T. giganticus is also provided. After critical evaluation of the genus we recognize 4 valid species and provide a taxonomic key to species.

Two new species of free-living marine nematodes,Adoncholaimus daikokuensissp. nov. andA. pseudofervidussp. nov., from the coastal area of northern Japan, are described and illustrated.Adoncholaimus daikokuensissp. nov. is similar to five congeners,A. derjugini,A. punctatus,A. oxyuroides,A. squaluscomb. nov. andA. filicaudacomb. nov. in the absence of a gubernaculum, but differs in the absence of a ventral swelling on tail, spicule length and buccal cavity length.Adoncholaimus pseudofervidussp. nov. is similar toA. fervidusin having large body size, short tail, similar positions of the excretory pore and nerve ring, short spicules, arrangement of subventral setae in posterior region of body in males, and a single pair of terminal pores of the Demanian system surrounded by small gland cells in females.Adoncholaimus pseudofervidussp. nov. differs fromA. fervidusin having smaller, more anteriorly located amphids, longer buccal cavity, absence of gubernaculum in the male, and a different position of the terminal pores in the female. Partial sequences of the mitochondrial cytochromecoxidase subunit I gene (309-337 bp) of the new species are provided for identification based on the DNA barcoding method.Metoncholaimoidesis proposed as a junior synonym ofAdoncholaimus. The new diagnosis ofAdoncholaimusand a key to species are provided.Adoncholaimus squaluscomb. nov.,Adoncholaimus filicaudacomb. nov., andAdmirandus papillatuscomb. nov. are proposed.

Three new species of Cumacea belonging to the genus Bodotria were collected from the Yellow Sea in Korea. Among them, Bodotria (Bodotria) hwanghaensis sp. nov. and Bodotria (Bodotria) pseudomaculosa sp. nov. share the dorso-lateral carina on the carapace and uniarticulated uropod endopod with other Korean Bodotria species. In contrast, the last one, Bodotria (Atlantobodotria) incarinata sp. nov. lacks the dorso-lateral carina on the carapace and has a biarticulated uropod endopod. The new species B. (A.) incarinata sp. nov. can be distinguished from all other Bodotria species by the combination of carapace without dorso-lateral carina or ridge, dorso-median carina marked over whole length of carapace, antero-lateral corner of carapace rounded, antennal notch shallow, maxilliped 3 merus and carpus dilated, pereopod 1 carpus not dilated, and pereopod 2 basis with plumose seta. The new species B. (B.) hwanghaensis sp. nov. can be distinguished from all other Bodotria species by the combination of carapace almost ovoid in dorsal view, carapace lower edge of mid-lateral depression forming a faint ridge, pereopod 1 carpus not dilated, and pereopod 2 basis without plumose seta. The new species B. (B.) pseudomaculosa sp. nov. can be distinguished from all other Bodotria species by the combination of carapace surface covered with coarse squamosa-reticulate patterning formed by large, shallow pits, carapace lower edge of mid-lateral depression forming an angular ridge, pereopod 1 carpus little dilated, and pereopod 2 basis with plumose seta. We described with full illustrations, including mouthparts for the three new species. Also, a key to the Korean Bodotria species is provided.
