A new species of Didogobius (Teleostei: Gobiidae) from the Adriatic Sea

Didogobius schlieweni sp. nov. is described from a single specimen collected among pebbles in shallow water at Unije island, near Cres, in the northern Adriatic Sea. The holotype has vivid dark and pale patterning, and is assigned to Didogobius on the basis of head neuromast patterns and meristic features. Diagnostic values of the latter are D2 I/12, A I/11, P 17, and LL 55–56. A key to species of the Chromogobius and Didogobius complex is provided.     

A new genus and species of Conchaspididae (Hemiptera: Coccoidea) from Florida,remarkable in lacking legs

A new genus of Conchaspididae, Asceloconchaspis gen. nov., is described for Asceloconchaspis milleri sp. nov., a new species from Florida, USA. Unlike other conchaspidids, the adult female and second instar of the genus lack legs. The presence of legs is one of the important, distinguishing characters at present separating the Conchaspididae from the Diaspididae. However, the new genus also possesses well-developed antennae and has multilocular disc pores on the abdomen in the adult female; these distinctly conchaspidid characters are never found in the Diaspididae. Asceloconchaspis is closely related to Fagisuga Lindinger, a monotypic genus with primitive characters described from South America on Nothofagus. A key to the four known genera of Conchaspididae is provided, and the morphology and distribution of the Conchaspididae are discussed.     

A new species of a misophrioid copepod from the near-bottom waters off Brazil

Phylogenetic relationships of millipedes in the subclass Penicillata (Diplopoda) with a key to the genera

Bristly millipedes (subclass Penicillata, order Polyxenida) are minute diplopods characterised by uncalcified cuticle and a body covered with unique tufts of bristles. The order is found worldwide and comprises less than 200 described species divided into three families, with many of the species and genera being poorly known. The first evolutionary analysis of the order presented here utilises both molecular (COI, 18S rRNA and 16S rRNA) and morphological data to examine monophyly of the families and subfamilies and the evolutionary relationships between them. Maximum likelihood analysis was based on molecular data only, whereas parsimony analyses were based on molecular data as well as combined morphological and molecular data. The results of these analyses with two different optimality criteria were incongruent in many aspects. Unlike parsimony, the likelihood result found strong support for a basal position of the family Synxenidae and separation of the order into two monophyletic clades corresponding to the two superfamilies Synxenoidea, containing the family Synxenidae, and Polyxenoidea, containing the families Polyxenidae and Lophoproctidae. Parsimony results did not support the existence of the two superfamilies. Both analyses resolved the family Synxenidae as monophyletic and Polyxenidae as polyphyletic, whereas the family Lophoproctidae was shown to be paraphyletic in likelihood and monophyletic in parsimony analysis. The subfamilies Monographinae and Polyxeninae were found to be monophyletic in the likelihood tree but parsimony suggested paraphyly of both. The results suggest that further revision of the systematics of the Polyxenida may be necessary. However, a much larger molecular data set will be necessary to clarify and provide stronger nodal support for phylogenetic trees and to confirm the relationships, particularly of the families Polyxenidae and Lophoproctidae. Molecular identification is likely to be an important tool for this taxonomically challenging order in future. A simplified key to the genera is provided.     

航班运行风险网络的传播与控制改进

为探究航班运行风险的产生、传播与控制过程, 首先统计华北区域航班运行数据共计76个风险节点。然后，采用偏秩相关系数构建风险网络, 再使用社团模块探测算法与三角最大滤波法验证网络适用性。并且, 提出一种适用于航班运行风险分析的SEIR(susceptible-infected-exposed-recovered)模型。根据动力学传播结果, 聚类定位网络传播中关键节点。最后, 采用前置预防与战术处置两类控制方案。计算结果表明，仅控制5个节点后, 感染峰值可降低18.44%, 峰值时间推后两个周期, 起降等重要操纵节点被感染次数平均下降11.74%。该方案在感染峰值、感染周期、重要节点感染3个方面的抑制效果均占优。以上结果证实, 所提方案可有效用于航班运行风险问题分析。     

绿色建筑发展关键主体动态博弈——基于供给侧结构性改革视角

 中国绿色建筑市场正处于稳步发展阶段，但仍然存在供需结构不合理、各方利益关系协调不均衡等问题。基于供给侧结构性改革视角，分析了绿色建筑发展过程中“供应侧”和“需求侧”两端正外部经济性特征，构建了政府与供、需两端关键主体动态博弈模型，提出了基于政府、房地产开发商和消费者的对策建议。通过研究，表明绿色建筑发展前期阶段存在正外部经济效应和市场失灵共生现象，供、需两端并不能满足帕累托效率的平衡量要求，只通过市场自身资源配置功能调节绿色建筑市场结构和各主体利益关系存在局限性，政府的适度干预有利于实现供、需两端最优利益组合和利益均衡，有助于加快实现传统建筑市场转型升级。     

A new ascid mite from St Helena with observations on the Protogamasellus complex (Acari: Mesostigmata)

A new genus, Protogamasellopsis (family Ascidae), is proposed to accommodate the type species Protogamasellopsis corticalis sp. nov and Protogamasellus diocorus Manson. The classification of the Protogamasellus complex is discussed and a new subgenus, Protogamasellodes (type: Protogamasellus hibernicus Evans), is erected. A key is given for the separation of the genera Gamasellodes, Protogamasellus s.lat and Protogamasellopsis.     

晚清小说《泪珠缘》之“仿红”管窥

Eustigmaeus floridensis sp. nov., a new mite species of the genus Eustigmaeus Berlese, 1910 (Acari: Stigmaeidae) from citrus in Florida

Eustigmaeus floridensis sp. nov. is described and illustrated based on female specimens collected from citrus trees in Florida, USA. The new species is closely related to Eustigmaeus arcuata, Eustigmaeus segnis and Eustigmaeus microsegnis, all known to occur in Florida. Eustigmaeus floridensis sp. nov. can be distinguished by larger dimples associated with setae sce, d₂ and e₁ containing at least four or more vacuoles centrally; dorsal body setae broadly lanceolate and feather-like, except c₂, which is slender; anogenital area with striae and one pair of serrated aggenital (ag1) and three pairs of serrated pseudanal (ps_1?3) setae. A key to the Eustigmaeus species known to occur across USA is also provided.
