A new large and colourful species of the genus Doto (Nudibranchia: Dotidae) from South Africa

A new species of the genus Doto is described from the Cape Peninsula of the Western Cape Province, South Africa. To date, the genus Doto is probably one of the more complex and poorly defined genera within nudibranchs. The very small body size and very similar external and internal features make this genus problematic and, therefore, poorly studied. Despite the large number of described species around the world, only three species are known to be present in South Africa: Doto coronata (Gmelin, 1791), Doto pinnatifida (Montagu, 1804) and Doto rosea Trinchese, 1881. Morphologically, Doto splendida sp. nov. is easily distinguished from all its South African congeneric species by its conspicuous colouration. In addition, mitochondrial and nuclear genes clearly separate the new species from other species from southern Africa. A molecular phylogeny based on two mitochondrial (COI and 16S) and one nuclear (H3) gene is herein presented. This phylogeny includes all available species of Doto (valid and unidentified) as well as several other traditionally closed related species retrieved from GenBank.

New data on Hydrobiidae systematics: two new genera from the Iberian Peninsula

The taxon Caprella acanthifera auct., usually considered to be one ‘highly variable’ species, is shown here to consist of a number of closely related species. In this paper three species of the group lacking an axillary spine near the insertion of gnathopod 2 are described and illustrated; the taxa with an axillary spine will be dealt with in a separate paper. This paper redefines Caprella acanthifera Leach 1814, sensu stricto; the nominal taxa C. hystrix, C. calva, C. aspera, and C. leptonyx are considered to be junior synonyms. Also described are C. stella sp.n., from starfish at the Azores and C. cavediniae sp.n., living among algae in the Mediterranean. The sources of apparent morphological variability in caprellids are discussed.     

雷州半岛近50年气候变化的多时间尺度分析

利用Morlet和墨西哥帽子的小波变换对雷州半岛地区的南部与北部的徐闻和湛江两地(1951～2003年)的年均温和年降水资料进行小波分析,结果表明：其二维小波的系数等值图可以清楚地显示出气候变化在不同时同尺度上的演变特征,结合小波的方差图得到该区的年均气温有2年、4年左右、准7年的周期振荡,年降水具有2年、4年、10～11年左右、准27年的周期振荡．气温与降水在不同层次上表现出不同的变化趋势,从短期的高频部分看未来的1～2年内气温仍会偏高、降水偏少．中小层次上的突变年份与厄尔尼诺发生的当年相关性不明显．     

The saproxylic hoverflies (Diptera: Syrphidae) of Serbia

The revision of the saproxylic hoverflies collected in Serbia from 1950 to 2010 has revealed a total of 56 species, of which Sphiximorpha subsessilis (Illiger in Rossi) is new to the Balkan Peninsula and Arctophila superbiens (Muller), Blera fallax (Linnaeus), Brachyopa panzeri Goffe, Brachyopa testacea (Fallén), Brachyopa vittata Zetterstedt and Chalcosyrphus piger (Fabricius) are new to Serbia. According to “Syrph the Net, the database of European Syrphidae”, 16 of the 56 species are threatened with extinction in Europe, while 6 species are “strictly protected” and 13 are “protected” under Serbian legislation. Distribution maps for each species, as well as new data on adult habitats, are provided. The conservation status of the saproxylic hoverflies of Serbia is discussed. The present study attempts to provide a basis for the conservation of the saproxylic hoverflies of this Balkan country.     

浅析我国电子信息产业的知识产权的战略定位问题——兼论山东半岛构建世界级电子信息产业中心的战略决策

世界电子信息产业发展的核心板块和产业竞争主战场在东北亚,主要参战者是日本、韩国和中国山东半岛三大企业集群。中国电子信息产业的国家知识产权战略核心定位,应当是山东半岛企业集群的全球专利战略。因此,我国应借鉴国外经验,在山东省启动省级知识产权战略试点工作,把山东半岛加速建成世界级电子信息产业中心。     

Nesomyrmex micheleae,a new ant species (Hymenoptera: Formicidae) from the Dhofar Governorate,Oman, with a synoptic list,distribution map and key to the Arabian Nesomyrmex

ABSTRACT

A new species of the myrmicine ant genus Nesomyrmex Wheeler, 1910, N. micheleae Sharaf sp. nov., is described and illustrated from Oman based on the worker caste. The new species is a member of the N. angulatus species group and can be diagnosed by the golden yellow gaster that contrasts with the dark brown body; the irregular longitudinal rugulose sculpture on the cephalic surface; and the finely punctate mesonotum and propodeal dorsum. A synoptic species list, an updated key and a distribution map to the Arabian Nesomyrmex species are presented. Continued ant species discoveries are central to large-scale diversity patterns, conservation biology and macroecology.

Expanding the taxonomic conundrum: Three new species of groundwater crustacean (Syncarida,Bathynellacea, Parabathynellidae) endemic to the Iberian Peninsula

Two new species of the genus Iberobathynella and one new species of the cosmopolitan genus Hexabathynella are described from the Iberian Peninsula. The three new species were found in the groundwater of caves and the gravelly bank of a river, two species in the north of Spain (Cantabria and Burgos) and one in the south (Sevilla). The two new species of the genus Iberobathynella present a unique combination of characters. These character combinations for the species from Cantabria are: thoracopod 8 female with wrinkled cuticle and two teeth; seven spines on the furca; nine spines on the sympod, three barbed and one plumose seta on the exopod and two barbed setae on the endopod of the uropod; maxilla with 0, 0 and 15 setae on the three segments, respectively; five teeth on the pars incisiva and six teeth on the pars molaris of the mandible and seven segments on the antennule. The combinations of characters for the species from Burgos are: antennule with seven segments; segment 5 of the antennule with one aesthetasc; mandible with four and five teeth on the pars incisiva and pars molaris respectively; maxillule with one seta on segment 1 and 14 setae on segment 3; segment 1 of the endopod of the thoracopod 1 with two setae; uropod with six spines on the sympod, four barbed setae and one plumose seta on the exopod and no setae on the endopod; furca with five spines and the thoracopod 8 female with wrinkled cuticle and two teeth. This last species has an exclusive character for the genus: the absence of setae on the endopod of the uropod. The new species of the genus Hexabathynella has six spines of similar length on the sympod of the uropod (in all other species within the genus the distal spine is longer than the others); the form of the antennal organ in the males is shown to be a new unique character for the genus; the maxilla has three and 13 setae on segments 2 and 3, respectively; the uropod has six spines on the sympod, three barbed setae on the exopod and two smooth setae on the endopod, the endopod is twice as long as the exopod and the shape of the female thoracopod 8 is unique.     

SHRIMP U-Pb zircon dating for lamprophyre from Liaodong Peninsula： Constraints on the initial time of Mesozoic lithosphere thinning beneath eastern China

It is undebated fact that the lithospheric mantle beneath eastern China was considerably thinned during the Mesozoic time. However, it has no adequate evidence for the exact timing when the lithosphere thinning started. The Liaodong Peninsula is located in the eastern segment of the North China Craton and is one of the important domains to explore the event of lithosphere thinning. SHRIMP U-Pb zircon dating and geochemical study were carried out for the lamprophyre dike swarm that intruded into the magnesite ore-beds in the Dashiqiao Formation of Paleoproterozoic Liaohe Group at the Huaziyu magnesite ore district, Liaodong Peninsula. The results indicate that these lamprophyre dikes were intruded in late Jurassic （155±4 Ma） and show some geochemical characteristics of potassic magmas. It is now accepted that the lithosphere thinning took place in the late Mesozoic, and the peak thinning stage occurred in early Cretaceous （130-120 Ma）. Considering the potassic mafic magmatism marking the onset of the lithospheric thinning, we therefore suggest that the studied late Jurassic potassic lamprophyre dike swarm could imply that the late Jurassic is the time that lithosphere thinning started.
