A new member of Sphenopsida,Neolobatannularia gen. nov. from Late Triassic of western Liaoning,China
WANG Junyou LI Tao LIU Zhiping GUO Bin KANG Ai NA Yuling LI Yunfeng WANG Hongshan BO Junchen SUN Chunlin 《世界地质(英文版)》2019,22(1)
A new genus Neolobatannularia Sun et Li gen. nov. with the type species Neolobatannularia liaoningensis Sun et Li sp. nov. from the Upper Triassic Yangcaogou Formation of Beipiao, Liaoning, China, is described in this paper. The new taxon is attributed to Equisetales of Sphenopsida based on its branch with internodes, node and leaves borne in whorls on nodes. It is a new member of the Mesozoic Sphenopsida. Although the new taxon shares some morphological characters with the genus Lobatannularia Kawasaki, a genus widely distributed in the Permian Cathaysia flora in East Asia, and the genus Lobatannulariopsis Yang from the Late Triassic of southwestern China, its unique branching pattern is markedly distinguished from the two known genera. Some Triassic known species of Lobatannularia may belong to the present new genus Neolobatannularia. 相似文献

A new species belonging to the genus Haloschizopera Lang,1944(Copepoda,Harpacticoida,Miraciidae,Diosaccinae)was identified based on the samples collected from the East China Sea,near the offshore of Zhejiang Province,East China.The new species is closely related to H.pygmaea Norman Sccot T.,1905 and shares a combination of the following features:A1 eight-segmented;A2 exp-2 with one distal seta,exp-3 with three setae;P1 endopodal segments subequal,enp-1 not exceeding exp-2;exp-3 of P3 with one inner seta,of P4 with two inner setae.The new species is characterized by the presence of one inner seta on P2 exp-3 of both sexes.It can also be distinguished from its congeners by the characters of female:P5 exopod subcircular,endopodal lobe extending beyond half-length of exopod;genital doublesomite ornamented with three dorsolateral rows of spinules on anterior part. 相似文献

Species,Thracia granubsa of the Family Thraciidae from the China Seas was first reported and described as new to science by Adams et Reeve (1850).
No other species was found there for more than 100 years until the author (1980) in his studies on Chinese bivalvia, discovered
the second new species,Trigonothracia jinxingae, described in this article.
This paper deals with 6 species, three of which are new to science, collected from the littoral and sublittoral zones of the
China Seas.
Type specimens are deposited in the Institute of Oceanology, Academia Sinica, Qingdao.

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. 相似文献

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. 相似文献

A new species of Liagora,L.perennis sp.nov.from Hawai’i,is described.Unlike dpecies of this genus in China,it is carpotetrasporangial,and at the place of expected carposporangia bears cruciately di-vided tetrasporangia,a detail which differentiates it from the usual species of Liagora without tetraspores that have been reported in China.Notes are provided on other Liagora species that have an impact on the taxonomy of species found in China. 相似文献

地理信息系统白20世纪60年代发展以来,已在世界范同内产生深远影响.我国地理信息系统自80年代起步,在80年代中后期地理信息系统高等教育开始起步,经历二十几年的发展,在2000年前后进入发展快车道.当前我国大陆地区开展GIS教育的高校已经从最初的几所高校扩展到百余所.尽管大陆地区地理信息系统本科阶段教育已基本普及,但各地地理信息系统教育发展并不平衡,尤其是硕士、博士学位点分布集中有限几个省市区中.因此,针对当前地理信息系统教育发展局面,对制约其发展的主要影响因素进行分析,并考虑在此情形下我国大陆地区地理信息系统教育的发展趋势,有助于明确影响地理信息系统教育发展的主要因素,更好地指导各省市区地理信息系统教育发展. 相似文献

Three new spades and a new variety of nannoplankton, Chrysochromulina papillata, Gaysochromulina chiton var. minuta, Paraphysomonas simplexocorbita and Paraphysomonas bisorbulina are reported in this paper. All were isolated from the preliminary culture samples of seawater collected from Jiaozhou Bay, Shandong, China. The three species occurred at Station 1(120° 14.56′ E, 36°4′N) in November 1984, the new variety at Station 2 (120° 16.35° E,36°4.5′N) in January, 1985. The morphological features, especially the structures of the scales of these new nannoplankton,. are described. The differences between the new species and the related ones are discussed; their movement and nutrition, and the temperature and salinity of their biotopes are also mentioned. 相似文献
