大型鼩鼱Beremendia(食虫目,鼩鼱科)在江南的首次发现及其古气候学意义(英文)

记述了在现代东洋界发现的鼩鼱类一新种:江南贝列门德鼩Beremendia jiangnanensis sp.nov.。化石产自长江以南安徽繁昌早更新世早期人字洞古人类遗址。新种的体型比该属已知种大;形态特征比我国渤海种B.pohaiensis原始,但比欧洲早上新世的B.fissidens进步。贝列门德鼩是喜湿耐冷的北方型动物,最早发现于欧洲北部上新统,曾广泛分布于欧洲和中亚高纬度地区,种群密度大,中更新世完全绝灭;它在东亚出现较晚,零星发现于华北早更新世地层中,其起源尚不清楚。新种乃是人字洞动物群的主要成员之一,该动物群由70多种哺乳动物组成。动物群的生态类型分析和分类统计表明,它与以往发现的早更新世南、北动物群及当地现代动物群截然不同,具有东洋界和古北界交错带动物群的特色,但动物组合特征为北方动物稍占优势,北方色彩较浓。贝列门德鼩和三门马(Equus sanmeniensis)、次兔(Hypolagus)、科氏仓鼠(Kowalskia)、模鼠(Mimomys)等大量北方型动物在我国东洋界的出现,足以说明第四纪早期有一次明显的降温事件。寒冷气候促使北方动物大规模南迁,古北区动物地理区系的界线在早更新世时要比目前更靠南;而且在古北界与东洋界之间确实存在南、北动物过渡带,其界线大致南移至现在的长江以南。贝列门德鼩在我国现代东洋界地区的首次发现,为研究该属的系统演化,探讨上新世一更新世气候转型时期鼩鼱类扩散事件及我国第四纪动物地理区系的演变将提供重要的信息。

DNA barcoding and morphology reveal exceptional species diversity of Scoparia (Lepidoptera: Crambidae) from the Hailuogou Glacier area,China

The genus Scoparia from the Hailuogou Glacier area in the south‐eastern fringe of the Tibetan Plateau of south‐western China is studied, nine species are revealed by combining DNA barcoding (658 bp of the mitochondrial gene cytochrome c oxidase subunit I, COI) and morphology. Studies show that Scoparia species from the Hailuogou Glacier area are 37.5% as many as all the previously known congeners in China. Six species are described as new to science: S coparia simplicissima Li sp. nov. , S coparia tribulosa Li sp. nov. , S coparia longispina Li sp. nov. , S coparia gibbosa Li sp. nov. , S coparia globosa Li sp. nov. , and S coparia annulata Li sp. nov. The female of Scoparia metaleucalis is described for the first time herein. All species are either diagnosed or described and illustrated, and a map of China showing the topography and localities where Scoparia species are recorded is also provided, including the species number of all the recorded localities. The results reveal the exceptional species diversity of Scoparia from the Hailuogou Glacier area, as well as demonstrate that the integration of DNA barcoding and morphological approaches is highly effective for indentifying scopariine moths in the Hailougou glacier area. All the studied specimens are deposited in the Insect Museum, Jiangxi Agricultural University, Nanchang, China. © 2014 The Linnean Society of London     

Palaeoginkgoxylon zhoui, a new ginkgophyte wood from the Guadalupian (Permian) of China and its evolutionary implications

A new taxon of ginkgophyte affinity Palaeoginkgoxylon zhoui gen. nov. et sp. nov. is described from the Guadalupian Lower Shihhotse Formation of the Hulstai coalfield, Inner Mongolia Autonomous Region (Nei Mongol), northern China, on the basis of the anatomical structures of the broad eustele and pycnoxylic secondary xylem. The anatomical structure of the new woody tree trunk resembles both the early gymnosperms of Eristophyton-Pitus types and the modern Ginkgo. Therefore, the new tree trunk is interpreted as representing a transitional stage in the evolution of Ginkgo from early arborescent lignophytes since the Early Carboniferous.

Les sciuridés des gisements karstiques du Miocène inférieur à moyen du sud de la France : nouvelles espèces, phylogénie, paléoenvironnement

We describe sciurids from Lower and Middle Miocene karstic sites located in the south of France. Four new taxa are recognized here: Atlantoxerus martini nov. sp., Atlantoxerus sp. 1, Freudenthalia cuencae nov. sp. and Aragoxerus nov. sp. The last two genera are recognized for the first time in the south of France. A comparison with the Iberian peninsula is carried out, it tackles the problems of diversity, phylogeny and settlement. Hypothesis concerning the predation of these terrestrial squirrels and paleoenvironment is proposed.     

An early isocrinid sea lily from the middle to late Anisian boundary (Middle Triassic) of south‐west China – evidence for a far‐east Tethyan origin of the family Isocrinidae

Abstract: The isocrinid sea lily Tyrolecrinus wugangi sp. nov. from uppermost middle to lowermost upper Anisian (lower Middle Triassic) strata of Leidapo near Qingyan, Guizhou Province, south‐west China, provides new data on the early phylogeny of the order Isocrinida. The new species is the earliest unequivocal representative of the family Isocrinidae. It predates all other known species of the genus Tyrolecrinus that come from upper Ladinian to Rhaetian strata and also all other known taxa of the Isocrinidae. Nevertheless, its stem is of fully developed isocrinid type and is characteristic of the genus, with consistently synostosial, rarely cryptosymplectial, distal nodal articular facets. These findings indicate that the Isocrinidae evolved prior to the late middle Anisian in the far‐eastern part of the Palaeotethys ocean, perhaps in the region forming today’s south‐west China, and spread to various other regions later in the Middle and Late Triassic. The genus Tyrolecrinus is revised and the new genus Bakonycrinus gen. nov. is erected.     

Discovery and Significance of the Genus Caulopteris from the Wuda Area of Inner Mongolia

Caulopteris wudaensis sp. nov. was collected from the Shanxi Formation of the early Early Permian in the Wuda area of Inner Mongolia, China. The genus Caulopteris is considered as the impression fossils of the tree fern stems. Most of the species under the genus Caulopteris are mainly distributed in the Eurameriean Province, whereas they are very rare in the Cathaysian Province. The discovery of the new species will provide some important evidences for the geographical distribution, ecology and evolution of the genus Caulopteris.

New genus of Ptereleotrinae (Gobioidei) from the South China Sea

A new genus and species Zagadkogobius ourlazon gen. et sp. nov. characterized by an unusual (for the subfamily Ptereleotrinae) combination of characters is described. A single specimen was collected at a depth of 73 m in the southwestern South China Sea to the south of the Anambas Islands. Based on the combination of characters, the new genus is most similar to the genus Nemateleotris. However, the species of the latter genus are associated exclusively with coral reefs. A key to the genera of the subfamily Ptereleotrinae is presented.

Late Pennsylvanian to Middle Permian revised algal and foraminiferan biostratigraphy and palaeobiogeography of the Lycian Nappes (SW Turkey): Palaeogeographic implications

Shallow-marine limestones associated to a Palaeotethyan seamount in the Teke Dere unit of the Tavas Nappe (Lycian Nappes, SW Turkey) are essentially latest Moscovian-Kasimovian in age. The wide range of microfauna and -flora of the series show biogeographic affinities comparable to those from the northern Palaeotethyan borders (especially to assemblages from the Carnic Alps, Urals, Donbass and Darvaz). These biogeographic affinities seem to persist until the end of the Early Permian (Artinskian). The Middle Permian fauna is represented by the typical warm, tropical assemblages known at the same time in the Palaeotethys (NW Caucasus, Darvaz, south China, Primorie and Japan), and in the Neotethys (Transcaucasia, central Iran, southern Afghanistan and Sibumasu). The new Kasimovian algae and incertae sedis Novantiellopsis elliottii n. gen. n. sp., Uvanellopsis fluegelii n. gen. n. sp., Tubiphytes rauzerae n. sp. and Asselodiscus davydovi n. sp. are described.
