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 rcoscalpellum liui sp. nov. is morphologically similar to A rcoscalpellum gryllum Zevina,but differs from the latter by the absence of longitudinal striae on the capitular plates and the presence of caudal appendages with few terminal setae.     

Galatheid squat lobster species from Chinese waters

Five galatheid squat lobster species belonging to four genera of two galatheid families are reported for the first time from Chinese waters, namely Lauriea simulata Macpherson and Robainas- Barcia, 2013, Phylladiorhynchus ikedai （Miyake and Baba, 1965）, Phylladiorhynchus integrirostris （Dana, 1852）, Babamunida sp., and Raymunida elegantissima （de Man, 1902）. The genera Lauriea Baba, 1971 and Babamunida Cabezas, Macpherson, and Machordom, 2008 have not previously been recorded from Chinese waters.     

A NEW SPECIES OF THE GENUS NEROCILA （ISOPODA： CYMOTHOIDAE） FROM THE EAST CHINA SEA

A new species of cymothoid Isopeda, Nerocila donghaiensis, collected from the body of a sciaenid fish, Johnius sp., is described in the present paper. The new species can be distinguished from the other species of genus Nerocila by its endoped of uropods with deep notch, sharply serrated on the lateral margin and strongly serrated on the medial margin; antennule with 1 st article swollen; dactyli of pereopods Ⅰ, Ⅱ, Ⅳ, Ⅴ swollen.     

Proteocephalus sinocyclocheili n. sp. (Cestoda: Proteocephalidae) in a fishSinocyclocheilus grahami tingi Fang from Yunnan, China

A new species ofProteocephalus from the fishSinocyclocheilus grahami tingi, a subspecies endemic to Fuxian Lake in Southwest China,is described. This is the first report of cestode from this host. The new species differs fromP. exiguus, P. Longicollis, P. parasiluri andP. torulosus, the only other species ofProteocephalus currently reported from China, by lacking an apical sucker, fromP. exiguus by having 45–108 rather than 24–54 testes per proglottis, and a maximum of 15 rather than 28 uterine diverticula; fromP.longicollis by having an average of 45–108 rather than 75–115 testes per proglottis and testes being in a single layer instead of 2 layers; and fromP. torulosus by having 45–108 instead of 150 testes per proglottis and testes being in 3–4 layers; and fromP. parasiluri by having 45–108 rather than 180 testes per proglottis. It resemblesP. percae, P. pollanicola, andP. thymalli in number of testes and uterine diverticula, but differs by lacking an apical sucker.Proteocephalus thymalli, like the new species, has a vagina that opens dorsally to the cirrus sac, butP. thymalli slao has postovarian testes, which the new species lacks. The possible significance of parasitological examinations of the other two subspecies ofS. grahami in two lakes close to Fuxian Lake is discussed in relation to host speciation and coevolution of the host-parasite system.     

Eualus heterodactylus sp. nov., a new hippolytid shrimp from Chinese coast of the Yellow Sea （Crustacea,Decapoda, Caridea）

A new species from the caridean family Hippolytidae, Eualus heterodactylus sp. nov. is described and illustrated based on the specimens collected from Chinese coast of the Yellow Sea. The new species is a part of an informal species group characterized by the possession of epipods on the anterior three pairs of pereopods, and is distinguished from other species of this group by the dactyli of the third to fifth pereopods possessing distinctly stair-like flexor margins in males.     

A Taxonomic Study of the Genus Tinocladia （Chordariales,Phaeophyta） in China Coasts I. Two new species, T. eudesmoides sp.nov, and T. zhangii sp.nov.

Two new species of the genusTinocladia Kylin (1940)T. eudesmoides Ding et Lu sp. nov. andTinocladia zhangii Ding et Lu sp. nov., are described.T. eudesmoides is mainly characterized by its longitudinally and transversely produced sub-cortical filaments from the medulla, its short uniseriate assimilating filaments, usually composed of 6–10 cells with slightly swollen and narrow ultimate cells, and its unilocular sporangia (60–115)×55–70μm, variable in size.T. zhangii is mainly characterized by its very solid frond, not rip apart by hands, its evident longer primary branches, its short and slender secondary branches, with very evident sub-cortical layer, and filaments divided repeatedly, and its large and small unilocular sporangia, with the latter borne on an evidently swollen pedicel.

Two New Species of the Genus finocladia Kylin （Chordaria-les, Phaeophyta） from Yellow Sea Coasts of China

Two new species of the genus Tinocladia Kylin, T. gracilis sp. nov. and T. microsporangii sp. nov,, are described. T. gracilis is characterized by its slender frond, variable size, infrequently branched medullary filaments, and short assimilating filaments with 2 - 7 cells. T. microsporangii is characterized by its medullary cells which are slightly larger than sub-cortical ones; narrow sub-cortical layer, usually consisting of 4- 6 cells and very small unilocular sporangia. The holotypes are deposited at the Herbarium of the Institute of Oceanology, Chinese Academy of Sciences, Qingdao, China.     

A new “tetrasporangial” species ofLiagora (Rhodophyta. Nemaliales) from Hawai’i

A new species ofLiagora, L. perennis sp. nov. from Hawai’i, is described. Unlike species of this genus in China, it is carpotetrasporangial, and at the place of expected carposporangia bears cruciately divided tetrasporangia, a detail which differentiates it from the usual species ofLiagora without tetraspores that have been reported in China. Notes are provided on otherLiagora species that have an impact on the taxonomy of species found in China. Dedicated to the memory of Zhang Junfu(C. F. Chang) whose studies on marine algae I respect highly, and whose good-humored friendship I treasure.     

Light and electron microscope observations onNephroselmis gaoae sp. nov. (Prasinophyceae)

Nephroselmis gaoae sp. nov. is described on the basis of light and electron microscope observations of cultured material originally collected and isolated from seawater of Jiaozhou Bay, Qingdao, China. The periplasts on the cell body and flagella are covered by five types of scales, two types on the flagella and three on the body. Among these, the morphology and the number of spines of large stellate body scales differ remarkably from those of previously described species ofNephroselmis. Apart from these, the unusual fine structure of the eyespot (stigma) is very characteristic. As in the other species ofNephroselmis, the eyespot lies immediately under the two-membraned chloroplast envelope; unlike the others, however, it is not composed of a number of osmiophilic globules, but consists of about 14 curved rod-shaped osmiophilic bodies arranged loosely and randomly. This feature distinguishes the present new species not only from the other species ofNephroselmis but also from the other motile algal species, the eyespots structure of which had been previously described. Contribution No. 2316 from the Institute of Oceanology, Chinese Academy of Sciences. This paper was presented at the XIVth International Seaweed Symposium held in Brittany, France, 1992.
