中国尾蛱蝶属系统发育分析——基于雄性外生殖器形态特征

在对中国尾蛱蝶属雄性外生殖器解剖研究的基础上,选取了23个雄性外生殖器解剖特征,利用Paup4.0b10系统发育分析软件,分析探讨了中国尾蛱蝶属系统发育关系。结果表明:中国尾蛱蝶属9个种分为2个支系,一支系由凤尾蛱蝶Polyura arja、窄斑凤尾蛱蝶P.athamas及黑凤尾蛱蝶P.schreiber3种组成,另一支系由二尾蛱蝶P.narcaea、沾襟尾蛱蝶P.posidonius、忘忧尾蛱蝶P.nepenthes、异纹尾蛱蝶P.mutata、大二尾蛱蝶P.eudamippus及针尾蛱蝶P.dolon6种组成。两大支系均以渐次方式演化;凤尾蛱蝶与窄斑凤尾蛱蝶、大二尾蛱蝶与针尾蛱蝶各自互为姊妹群关系。

对喜马拉雅和横断山地区特有的水龙骨科的宽带蕨属Platygyria Ching&S.K.Wu植物进行了形态学、分类学、生态和植物地理学的观察与分析,探讨了该属植物的系统位置、亲缘关系和生态适应性,推测宽带蕨属是随着喜马拉雅山脉的隆升,由瓦韦属Lepisorus（J.Sm.）Ching网眼瓦韦群植物适应高寒生态环境演化而来的新生类群。确定宽带蕨属有5种,即川西宽带蕨P.soulieana（Christ）X.C.Zhang&Q.R.Liu、多变宽带蕨P.variabilis Ching&S.K.Wu、耳基宽带     

Une nouvelle espèce de Podocnemis (Pleurodira, Podocnemididae) provenant du Néogène de la formation Solimões, Acre, Brésil

A Neogene turtle from Brasil is described. It represents the first find of a new species close to the extant Podocnemis sextuberculata. Both species constitute a new clade in the genus. The synapomorphies they share and the differences between them are given. P. negrii nov. sp. is the second fossil species of the genus, after P. bassleri from the Neogene of Peru, which constitutes another clade with the extant P. expansa. The relationships between these two clades and the other species of the genus are not determinate.     

中国新记录种黑毛地蜂记述（膜翅目：地花蜂科：毛地蜂亚科）

Species of the planktonic diatom genus Pseudo-nitzschia of the Pacific coasts of Mexico

Species of the diatom genus Pseudo-nitzschia are common in the marine phytoplankton world-wide. Some species of this genus have been proved to be source of domoic acid (DA), a powerful toxin causing Amnesic Shellfish Poisoning (ASP) in humans and probably mass mortality in sea birds and mammals. Net plankton samples obtained during several cruises and seasons from the Pacific coasts of Mexico: western coasts of Baja California, Gulf of California, coasts of the tropical Pacific of Mexico (including the Gulf of Tehuantepec), were analyzed to study the species of the diatom genus Pseudo-nitzschia. Four species ( P. australis, a presumed toxic species, P. fraudulenta, P. lineola, P. pungens) and one former species of the genus, Nitzschia americana were recorded and studied by light and electron microscopy. The most common species was P. pungens, widely distributed along the Pacific coasts of Mexico. All other species appeared occasionally and in low relative abundances. The probable misidentification of P. australis as P. seriata is discussed, as well as the presence of another potentially toxic species, P. delicatissima, in the Gulf of California. No case of toxicity (ASP) has been fully documented and therefore related to toxic Pseudo-nitzschia species in the Gulf of California. This revised version was published online in July 2006 with corrections to the Cover Date.

Description of three new species of Paractenopsyllus genus (Siphonaptera: Leptopsyllinae) from Madagascar

The males of three new and rare species of the Malagasy endemic genus Paractenopsyllus Wagner, 1938 are described. Paractenopsyllus beaucournui, P. oconnori and P. raxworthyi have been collected on endemic small mammals and the black rat. As for others species of the genus, biotopes are rain-forests of the central highlands or the northern mountains of Madagascar. Two of the described species were collected at elevations lower than typical for the genus and below the limits of the highland bioclimatic zone. Morphological affinities between these new species and those already described provide taxonomic framework for the genus. An updated identification key is provided for the diagnosis of all the 20 Malagasy species of Leptopsyllinae.

中国拟扁枝衣属的研究

拟扁枝衣属Pseudevernia隶属于子囊菌门Ascomycota,茶渍目Lecanorales,梅衣科Parmeliaceae。迄今已知6种,即粉芽拟扁枝衣P.soralifera、细拟扁枝衣P.cladonia、粗拟扁枝衣P.intensa、茶渍拟扁枝衣P.consocians、橄榄陶拟扁枝衣P.olivetorina及拟扁枝衣P.furfuracea。后三种地衣之界定是在形态特征相似但仍有区别的前提下,以其各自所含次生代谢产物之不同与地理分布区之差异为根据的。茶渍拟扁枝衣含有茶渍酸;裂芽发育良好而密度中等;裂片狭窄,为北美所特有。橄榄陶拟扁枝衣含橄榄陶酸;裂芽较稀少;裂片狭长;分布区以北欧为主,延伸至北非及西亚,如巴基斯坦。而拟扁枝衣则含袋衣酸;形态多变;分布区以南欧洲为主,遍布于整个欧洲,向南延伸至北非,向东延伸至亚洲,如蒙古等。本文首次报道了该属地衣在中国的分布。文中除了对拟扁枝衣进行形态、化学及分布类型的描述外,还配有该种的照片以及该属已知种的检索表。

The genus Plectranthus in India and its chemistry

Phytochemical constituents isolated from Indian species of the genus Plectranthus reported up to 2009 are compiled. In India, the genus Plectranthus is found in all the habitats and altitudes, particularly in the Himalaya, the Southern Ghats, and the Nilgiri region. P. amboinicus, P. barbatus, P. caninus, P. mollis, P. coetsa, and P. incanus are the most common species found in India. Phytochemical studies of the genus revealed that Indian Plectranthus species are rich in essential oil, and that the most abundant secondary metabolites are diterpenoids, i.e., labdanes, abietanes, and ent-kauranes, as well as triterpenoids.     

Ultrastructure and taxonomy of Paraphysomonas (Chrysophyceae) and related genera 2

This is the second of two accounts reporting on the occurrence and systematics of freshwater species of the colourless chrysophycean genus Paraphysomonas in the Cambridge area, using electron microscopy of whole mounts of both cells and scales and sections of scales. Twenty species are included here, eleven of which are new: P. cancellala, P. canistrum, P. homolepis, P. ignivoma, P. limbata, P. morchella, P. runcinifera, P. stelligera, P. stephanolepis, P. subquadrangularis and P. undulata. Five new subspecies are also established: P. circumvallata ssp. mediogranulata, P. poteriophora ssp. manubriata, P. punctata ssp. atrema , ssp. microlepis and ssp. simplicior. P. diademifera (Takahashi) comb. nov. [= Lepidochromonas diademifera (Takahashi) Kristiansen] has been included in Paraphysomonas since it has been found to be colourless and not pigmented as originally described and also to possess scales of a similar structure to those in other species of Paraphysomonas. One previously described species, P. inconspicua Takahashi, is here considered as a synonym of P. butcheri Pennick & Clarke. P. vacuolata Thomsen is removed from Paraphysomonas since it has been found to possess a chloroplast and will be included in a new genus in the third paper of this series. The 37 presently known species of Paraphysomonas have been arranged in 11 different groups according to similarities in scale structure. Consideration of the possible evolution of scale structure in Paraphysomonas and the possible interrelationships within the genus led to the conclusion that all species should be included in a single genus.     

中国西南特有翅茎草属的种间界定——基于形态学和分子系统学分析

翅茎草属(Pterygiella)是中国西南地区特有的半寄生植物.翅茎草属4种植物形态差异不显著,种的界定依据较模糊;此外,杜氏翅茎草2变种的划分依据也存在疑问.本研究选取了翅茎草属4种13个居群,通过数量性状的主成分分析和质量性状的非加权组平均法聚类分析;结合叶绿体4个片段(即atpB-rbcL、trnD-trnT、trnS-trnG和sbA-trnH)和核基因组的ITS片段研究,对该属下的种类划分作了重新界定.研究表明:翅茎草属应包括3种,即翅茎草、杜氏翅茎草和圆茎翅茎草;川滇翅茎木应作为圆茎翅茎草的变种.对杜氏翅茎草指定了后选模式,该种仅包括茎无毛的个体,而茎疏被毛的个体应归入翅茎草中.基于以上研究结果,本文提出了一个新的翅茎草属分种检索表,并做了分类修订.
