Three new species of Batrachospermum Roth （Batrachospermaceae, Rhodophyta） in China

Three new species of Batrachospermum Roth (Batrachospermales, Rhodophyta) from China are described in this paper. B. yunnanense sp. nov. has long-cylindrical trichogynes with long stalks and is diagnostic of section Virescentia. Within this section, B. yunnanense is similar to B. helminthosum Bory emend. Sheath et al., but it is dioecious and has curved carpogonial branches, while the latter is monoecious and has straight carpogonial branches. It is also similar to B. transtaganum Reis, but it differs from the latter in long carpogonia,big carposporophytes and carposporangia. It is considered that B. nothocladoideum sp. nov. is assigned to section Contorta, subsection Kushiroense, because its carpogonial branches are twisted and gonimoblast filaments are loosely agglomerated. This new species similar to B. iriomotense Kumano, but with short fascicles, long-ovoid or subpyriform cells, numerous terminal hairs, long-ellipsoid trichogynes, big carposporophytes and small carposporangia. The plant is quite tough and cartilaginous and similar to Nothocladus in gross morphology, but its carposporophytes are compact instead of diffuse. This shows that it may be a transitional species between section Contorta and genus Nothocladus. So, B. transitorium sp. nov. should belong to section Contorta, subsection Kushiroense, because of its curved or twisted carpogonial branches and loosely agglomerated gonimoblast filaments, with globose or subglobose cells in fascicles similar to B. spermatiophorum Vis et Sheath, but no colourless spermatiophores. In terms of small and numerous carposporophytes, B. transitorium sp. nov. is similar to some species of section Batrachospermum. However, their other features are unique, indicating its transitional nature between section Contorta and Batrachospermum.     

Three new species of Batrachospermum Roth (Batrachosper-maceae,Rhodophyta) in China

1 INTRODUCTION The first published records of genus Batra-chospermum Roth in China are from Jao (1941), when eleven taxa were reported. Since then, Shi, Hu and Kumano (1993), Shi (1994a, 1994b), Hua and Shi (1996), Xie et al. (1999, 2003), Xie and Shi (2003) have described in more detail the species from China. To date, 23 taxa of Batrachospermum Roth in China have been reported, of which, B. yunnanense, B. nothocladoideum and B. transito-rium are new species of this genus, and are…     

Pseudosmittia aizaiensis,a new species of orthocladiinae (Diptera,Chironomidae) from human province of China

Male and female adult midges ofPseudosmittia aizaiensis sp.n. are described and illustrated with figures of morphological characters. The inferior volsella of gonocoxite with large lobes, the long but equal width gonostylus, and the small projection in basal part of outer margin are the characters that may separate this species from others. One larva of this genus is purely aquatic in habitat and is associated with Cricotopus bicinctus,Cardiocladius capucinus andPolypedilum sp. in the same algae debris (Spirogyra sp.) of the Dunghe River. Further, the larva's very short SI and SII bifids, its 5 pairs of lateral teeth on mentum and its absence of premandible brush are the characters that may also separate this species from any known species of this genus.     

Two new species of Ophidiasterid sea-stars from the vicinity of Diaoyudao,East China Sea

Two new species of the asteroid family Ophidiasteridae are described from two specimens collected by commercial fishery vessels of Qingdao from the vicinity of Diaoyudao (25°45′N, 123°15′E), East China Sea.Hacelia tuberculata sp. nov. shows affinities withH. tyloplax (H. L. Clark, 1914) andLinckia gracilis sp. nov. is related toL. laevigata (Linnaeus). Contribution No. 1163 from the Institute of Oceanology, Academia Sinica.     

A new species of ciliates,Hemiophrys polymicronuclei sp. nov. from Donghu Lake,Hubei province

A new species of ciliatesHemiophrys polymicronuclei sp. nov. from Donghu Lake is described. It is characterized by its colorless to yellowish, soft, flat and spindle-shaped body with four micronuclei. The right side of the body is a little more convex than the left side, and more transparent at both anterior and posterior ends. Its slit-like cytostome accounts for 1/4 of the body length on the left side without any trichocyst. There are two rows of trichites near the right anterior end, 6–8 straight bristles on the pellicle opposite the cytostome, 23–25 rows of kinetides on the right side of the body, two ellipsoid macronuclei and many contractile vacuoles in the cytoplasm.     

Muelleria pseudogibbula,a new species from a newly recorded genus (Bacillariophyceae) in China

The genus Muelleria is reported for the first time from China in this paper. The new diatom species M uelleria pseudogibbula sp. nov. was observed during a survey of diatoms from Zoigê Wetland, Sichuan Province, China. The morphological characters of this new species were documented by light and scanning electron microscope and compared with similar species. M. pseudogibbula is characterized by its lanceolate to linear-lanceolate valve outline with rounded apices, two longitudinal canals running parallel to each side of the raphe, proximal ends of the raphe deflected to the same directions and finishing before the first row of areolae, and curved distal raphe ends, forming two divergent branches.     

A new species of Cymbasoma Thompson, 1888(Copepoda: Monstrilloida) from the Fujian coast,China

A new monstrilloid copepod species,Cymbasoma cheni sp.nov.,from Meizhou Bay(an embayment in Fujian Province,southeastern China)is described and illustrated.The diagnostic character of the new species is the structure and armature of the fifth leg,which is represented by a single lobe armed with three naked setae subequal in length.The new species closely resembles Cymbasoma bowmani SuarezMorales and Gasca,1998 in the structure of the fifth legs,and the body proportions,including total body length,and relative lengths of the cephalothorax and the genital double somite.However,Cymbasoma cheni sp.nov.is distinguished by lack of cuticular ornamentation on the cephalothorax,the position of the oral papilla,and the structure of the fifth leg with three naked setae.Although the structure of the fifth legs is similar in Cymbasoma cheni sp.nov.and Cymbasoma quintanarooense(Suarez-Morales,1994),the new species can be easily distinguished from Cymbasoma quintanarooense by the relative length of the antennule,differences in the genital double-somite and the ovigerous spines,and the shape of ocelli.This is the sixth record of this genus from China seas.     

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     

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 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 of Eunice (Polychaeta: Eunicidae) from Hainan Island, South China Sea

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.
