A new species of Cerithium （Gastropoda： Cerithiidae） from the South China Sea

Specimens of a new species of Cerithiidae, Cerithium mangrovum n. sp., were collected during two surveys along the coasts of Hainan and Guangdong Province, China. Usually associated with potamidid snails, this species often occurs in large populations between the mid-high tidal zones in a range of habitats, including mangroves, grass beds, silt, mud, and coral reefs. C. mangrovum n. sp. has a slender and tapering shell and the straight-sided whorl bears three aligned beaded spiral cords. The thick outer lip has a wide posterior sinus. It morphologically resembles C. coralium Kiener, 1841. The shell of C. coralium is usually larger and wider and the spiral cords are not as beaded as in C, mangrovum n. sp. Its radula has a rachidian tooth with a shallow, wide, median basal projection while the rachidian tooth of C. mangrovum n. sp. has a moderately long, median basal projection.

Ataxonomic survey of benthic marine animals from coastal regions of Hainan Island, South China Sea, revealed specimens of a new species of Eunice (Polychaeta: Eunicida: Eunicidae), Eunice uschakovi n. sp., collected from the intertidal zone. The species belongs to the group of Eunice that has yellow tridentate subacicular hooks and branchiae scattered over an extensive region of the body. It resembles E. miurai and E. havaica in having both bidentate and tridentate falcigers, but can be readily distinguished by branchial features. Comparisons between E. uschakovi and the two related species are presented.

A new species of Lataxiena Jousseaume, 1883 (Gastropoda: Muricidae) from the East and South China Seas

A new muricid gastropod species,L ataxiena lutescena sp. nov.,is described and illustrated. The new species was recognized during reidentification of the Muricidae collection in the Marine Biological Museum,Chinese Academy of Sciences,Qingdao. The specimens of the new species were collected from the East and South China Seas off Fujian,Guangdong,and Hainan Provinces. Lataxiena lutescena sp. nov. is similar to Lataxiena blosvillei(Deshayes,1832) in general shape,but can be distinguished from the latter by the shell sculpture and radular characteristics. Lataxiena lutescena sp. nov. also resembles Lataxiena bombayana(Melvill,1893),but differs from that species in the shell shape and anal notches and in lacking short spines on the shell.     

A new species of Phyllochaetopterus Grube,1863(Polychaeta:Chaetopteridae) from Hainan Island,South China Sea

Phyllochaetopterus species are widely distributed on the coast of China.Here,Phyllochaetopterus hainanensis n.sp.,a new species collected from Hainan Island(China),is reported.It is characterized by having a V-shaped peristomium,two eyespots covered by a pair of large curved peristomial notopodia(cirri located beneath the palps),13-14 chaetigers in the anterior body region,with three enlarged modified chaetae on the fourth notopodium,and more than five chaetigers in the middle body region.The modified chaeta has a slightly inflated head with an obliquely truncate end.The new species resembles Phyllochaetopterus socialis Claparede,1869,but differs in the shape of peristomial notopodia and peristomium.Twelve species of Phyllochaetopterus have been described from the Pacific Ocean,including the new species described here.An identification key to the known Pacific species is provided together with a brief discussion of the taxonomic value of the eyespots for the genus.     

A new species ofSolieria from China

A morphological study of a marine red alga from China, previously identified by various authors as “Solieria mollis (Harv.) Kylin”, has been shown to be an undescribed species ofSolieria. The present new speciesSolieria tenuis is characterized by the slender branches, the unbranched and nonseptate connecting filament and the discoid holdfast surrounded by prop branches resembling proproots of land plants. Contribution No. 989 from the Institute of Oceanology, Academia Sinica.     

On a new species ofPavlova (Prymnesiophyceae) from China

Pavlova viridis sp. nov. is described on the basis of light and electron microscope observations. The material was collected from the coast of haiyang county of Shandong, China. It is characterized by 1) yellowish green to green chloroplast, 2) rudimentary short flagellum 0.3 μm long and hook-shaped, 3) long flagellum with small spherical knob-scales, 4) absence of pyrenoid and stigma, and 5) marine habitat. This new species andP. salina seem to be most closely related to each other but their colour, the insertion of their three appendages, the shape of their knob scales, and their cell periplasts are quite different from one another.

A new species of Parodontophora (Nematoda: Axonolaimidae) from the intertidal zone of the East China Sea

This study described a new species of free-living nematode discovered in the intertidal mudflat of Ximen Island,East China Sea.The new species,designated Parodontophora longiamphidata sp.nov.,was characterized by a cylindrical body with tapering extremeties;cuticle smooth without somatic setae;four short cephalic setae;cylindrical buccal cavity with six clawlike teeth at the top of stoma;pharynx cylindrical with widened base;amphidial fovea crook-shaped with elongated scalariform branch extending past level of base of pharynx and ventral gland;ventral gland cell long-oval shaped located posterior to pharyngo-intestinal junction;excretory pore at level of middle of buccal cavity;tail conico-cylindrical with enlarged tip;three caudal gland cells,male spicules arched with cephalic proximal end and tapered distal end;gubernaculum with dorso-caudal apophysis;female with two opposed outstretched ovaries;and vulva at slightly post-midpoint of body length.This new species was close to P.wuleidaowanensis Zhang,2005 and P.polita Gerlach,1955 in terms of long amphidial fovea branch.The newly found species was easily distinguishable from the two documented;its amphidial fovea branch(255–290 μm versus 72–106 and 125–150 μm) was obviously longer.Key to the Parodontophora species with a longer amphidial fovea branch was given.     

Two new species of the genus anthenoides (Echinodermata: Asteroidea) from southern China

Two new species of the genusAnthenoides from the southern China are described.A. laevigatus sp. nov. shows affinities withA. epixanthus. A. tenuis sp. nov. is related toA. cristatus (Sladen). Contribution No. 1472 from the Institute of Oceanology, Academia Sinica     

SCREENING OF AGGLUTININS IN MARINE ALGAE FROM FUJIAN COAST OF CHINA

Thirty-three species of marine algae belonging to Rhodophyta, Phaeophyta and Chlorophyta from the Fujian coast were examined for agglutinins with different animal and human erythrocytes. Protein extracts from 26 species were active against at least one type of the erythrocytes tested. There were 3 species (Grateloupia imbricata, lshigefoliacea and Entermorpha prolifera) whose extracts could agglutinate all the erythrocytes used. The lowest protein concentration required to produce erythrocyte agglutination varied remarkably, from 3.1μg/ml to 500μg/ml . The strongest activity was found in the agglutina-tion of rabbit erythrocytes by Gloiopeltis furcata extract. Inhibition assays performed with nine mono- and bisaccharides indicated that agglutinations of rabbit erythrocytes by extracts of 7 species were inhibited by one or more types of the sugars assayed. The agglutinating activity shown by extracts of most species wasnot affected when the test solution was heated to 90℃, but was lost at 95℃ - 100℃. A few extracts losttheir activity at 60 RS, 65 RS and 75 RS, respectively.     

Two new species of the genusDorylaimopsis Ditlevsen, 1918 (Nematoda: Adenophora,Comesomatidae) from the Bohai Sea,China

Two nematode species of the genusDorylaimopsis (Family Comesometidae) from the Bohai Sea are described.Dorylaimopsis rabalaisi n. sp. similar toD. punctata Ditlevsen, 1918 from which it can be separated by the small size, short and simple spicules without ventral apophyses or joint line.Dorylaimopsis turneri n. sp. differs from the closest speciesDorylaimopsis angelae (Inglis, 1967) by its higher values of de Man ratio ‘a’, much shorter spicules and higher ratio of gubernacular to spicules length. A key to species of the genus based on the key by Jensen (1979) is given. This project was supported by the National Science Foundation, No: 3860804
