A New Species

A new species of the genus Austinogebia Ngoc-Ho, 2001, A. monospina n. sp., collected from the Bohai Sea and theYellow Sea, is described and illustrated. It is closely allied to A. spinifrons (Haswell, 1881) but differs markedly in the rostral ornamentation, with one infrarostral spine and the unarmed lower margin of antennal peduncle.

A new species of the upogebiid mud shrimp genusAustinogebiaNgoc-Ho, 2001,A. liuin. sp., collected from the Bohai Sea, is described and illustrated. It is closely similar toA. takaoensis(Sakai & Türkay, 1995) andA. spinifrons(Haswell, 1881) in the fixed finger of the male pereopod 1 bearing a large blunt tooth on the outer (or lateral) surface, but differs markedly from the latter two in the rostrum being 1.7 times as long as its basal width, and the lower margin of the antennal peduncle being unarmed, respectively.

Abstract A new species of the caridean family Thoridae, Lebbeus liui sp. nov., is described from the Bohai Sea, China. It belongs to the group characterized by the presence of epipods on the third maxilliped to third pereiopod. The new species is most similar to L. fasciatus and L. speciosus. It differs from the above two species by the number of the dorsal teeth and the spacing of those on the rostrum, and by the posterior median margin of the telson not produced into a triangular tooth.

A New Species

A new species of the genus Thalassironus de Man, 1889 was discovered during several surveys of the offshore marine ecosystem in Korea. This new species belonging to the family Ironidae, Thalassironus koreanus sp. nov., shares general morphological traits of the genus such as an optically smooth cuticle, buccal cavity consisting of two parts with three movable teeth and thick cuticularized walls, six rounded lips with ten cephalic setae, slit-like amphid and short conical tail with caudal glands present. The new species is most closely related to T. bohaiensis, first discovered in the Bohai Sea, in terms of body ratio (a, b, c, c’) and general morphology, but differs by its generally longer and larger body structures, cervical setae at the level of the buccal cavity, paired somatic setae distributed along the body, and longer/larger spicule. A description of Thalassironus koreanus sp. nov., diagnosis of the genus, emended pictorial key for the genus and discussion of important characteristics for the genus is provided.

A New Species

Onychostenhelia bispinosa sp. nov. is described from material collected from the Bohai Sea, China. It differs from the type and only known species of Onychostenhelia in the setal formula of the swimming legs, the form of the setae on the baseoendopod of P5 in both sexes, the female rostrum, the structure of the sexually dimorphic P4 exopod in the male, and size. Onychostenhelia, Cladorostrata and Delavalia belong to a core group within the Stenheliinae that exhibits an unusual morphology in the maxillule, the exopod and endopod being confluent at base but not actually fused to the supporting basis. Based on this circumstantial evidence it is postulated that in biramous limb patterning both exopodal and endopodal primordia are recruited from a common precursor and, consequently, patterns of axial diversification in crustacean limbs and the mechanisms of segmentation that establish them may have to be reinterpreted. Previously published evidence supporting the monophyly of the Stenheliinae is reviewed and a dichotomous key to the nine genera of the subfamily Stenheliinae provided.

A New Species

Increasing discoveries of new species of the genus Melanochlamys Cheeseman, 1881 in the recent years indicate that the biodiversity of this group remains underestimated. Recently, several aglajid sea slugs were collected from Laizhou Bay, Shandong Province, China. Morphological observation of their external and internal anatomy revealed that they represent an undescribed species of Melanochlamys. This new species, Melanochlamys aquilina sp. nov., is closely related to Melanochlamys fukudai Cooke, Hanson, Hirano, Ornelas-Gatdula, Gosliner, Chernyshev & Valdés, 2014 in body size and dark external coloration, but can be differentiated from the latter by features of both shell and male reproductive organ. Phylogenetic analyses of two mitochondrial (COI, 16S rRNA) and a nuclear (H3) genes using Bayesian inference, maximum likelihood, and species delimitation analysis also support the separation of Melanochlamys aquilina sp. nov. from its related congeners.

Two new species of the family Xyalidae from the Laizhou Bay of the Bohai Sea, China are described and illustrated herein. Daptonema papillifera sp. nov. is characterized by relatively small body size, L-shaped spicules with a large cephalate proximal end, triangular gubernaculum with a dorsal apophysis, 5–6 conjoint precloacal cuticularized spines and two ventral papillae located at the middle of the tail. Daptonema papillifera sp. nov. is easily distinguished from the other species in this genus by having 5–6 conjoint precloacal cuticularized spines and two ventral caudal papillae. Pseudosteineria anteramphida sp. nov. is characterized by eight groups of long subcephalic setae located posterior to amphideal fovea, curved slender spicules with cephalate proximal end and tapered distal end, tubular gubernaculum without apophysis, precloacal supplements absent, and a short precloacal seta present. In comparison with its most similar congeneric species, P. ventropapillata Tchesunov, 2000 the new species differs in having smaller body, not jointed cephalic setae, absence of precloacal supplements and absence of gubernacular apophysis.

The morphology and infraciliature of a new oligohymenophorean ciliate, Cinetochilum ovale n. sp., isolated from the littoral sediment of the Bohai Sea, northern China, were investigated using live observations and silver impregnations. This new species as follows: size about 20–30 × 15–25 µm in vivo, body oval in outline, with 12–13 bipolar somatic kineties; scutica consisting of two short rows of kinetosomes, positioned near the end of somatic kinety 1; the anterior-most row of its membranelle 1 is distinctly detached from the remaining two rows; three postoral kinetofragments and a cyrtos-like structure at the deep portion of the buccal cavity always present; one macronucleus and one micronucleus; single contractile vacuole terminally located. A key to all known Cinetochilum species is updated.
