short head with a small, simple fastigium, theprothoracic legs being inserted near the posteriormargin of the prothorax, and the absence ofspines on the metathoracic tibiae. The discoveryof Eoproscopia extends the geological range ofthe family by approximately 110 myr and confirmsthe presence of stem-group proscopiids inthe Atlantic rift zone of South America duringthe Early Cretaceous.2008040376意 大 利 Sicily Lercara 组 ( 中 三 叠 统 - 卡 尼阶 ?) 中 的 二 叠 纪 介 形 类 = Permian Ostracodsfrom the Lercara Formation (Middle Triassic–Carnian?), Sicily, Italy. ( 英 文 ). Crasquin S; CarcioneL; Martini R. Palaeontology, 2008, 51(3):537-560A rich, diverse Permian ostracod fauna hasbeen recovered from the red and grey, laminatedshales and quartz-rich shales of the Triassic LercaraFormation. Forty-seven species have beenidentified, 13 of which are newly described here;they belong to 26 genera of which three are new:Anahuacia lercaraensis sp. nov., Aurigerites siciliaensissp. nov., Bairdia portellaensis sp. nov.,Cristanaria? katyae sp. nov., Fabalicypris gruendelisp. nov., Lethiersa salomonensis gen. etsp. nov., Lethiersia sinusoventralis gen. et sp.nov., Portella trapezoida gen. et sp. nov., Siciliellaelongata gen. et sp. nov., Siciliella infernespinosagen. et sp. nov., Siciliella prima gen.et sp. nov., Siciliella quadrata gen. et sp. nov.,and Siciliella spinorobusta gen. et sp. nov. Theassemblages contain or are composed of palaeopsychrosphericforms, which are regarded asindex fossils for deep environments. Thebathymetry of the different associations in life isevaluated.2008040377Euarthropods 上 茎 群 的 头 部 结 构 = Headstructure in upper stem-group Euarthropods. ( 英文 ). Budd G E. Palaeontology, 2008, 51(3): 561-573Continuing debate over the evolution andmorphology of the arthropod head has led toconsiderable interest in the relevance of the evidencefrom the fossil record. However, disputeover homology and even presence of appendagesand sclerites in Cambrian arthropods has resultedin widely differing views of their significance.The head structures of several importanttaxa, Fuxianhuia, Canadaspis, Odaraia, Chengjiangocarisand Branchiocaris are redescribed,revealing the essential similarity between them.In particular, all possessed an anterior sclerite,probably followed by a large posterior, ventralsclerite that is likely to be homologous to thehypostome of trilobites. The presence of a similarfeature in Sanctacaris is also possible, butless well-supported. An anterior sclerite, usuallybearing eyes, as in Fuxianhuia, appears to be awidespread feature of basal arthropods. Whetheror not this sclerite represents an original articulatingprotocerebral segment on its own is, however,open to debate.2008040378联 合 王 国 约 克 郡 南 洞 站 采 石 场 ( 侏 罗 系 上 卡洛 夫 阶 ) 牛 津 粘 土 中 一 甲 螨 ( 蛛 形 纲 : 蜱 螨亚 纲 ) = An Oribatid Mite (Arachnida: Acari)from the Oxford Clay (Jurassic: Upper Callovian)of South Cave Station Quarry, Yorkshire, UK.( 英 文 ). Selden P; Baker A S; Phipps K J. Palaeontology,2008, 51(3): 623-633A single specimen of a new species of oribatidmite belonging to the genus Jureremus Krivolutsky,in Krivolutsky and Krassilov 1977, previouslydescribed from the Upper Jurassic of theRussian Far East, is described as J. phippsi sp.nov. The mite is preserved by iron pyrite replacement,and was recovered by sieving fromthe Oxford Clay Formation (Jurassic: UpperCallovian) of South Cave, Yorkshire. It is thefirst record of a pre-Pleistocene mite, and thesecond species record of the family Cymbaeremaeidae,from the British Isles; also, it is onlythe third record of Acari from the Jurassic Period.The presence of a terrestrial mite in a sedimentarysequence of open marine origin is noteworthy,and suggestions for its mode of transport tothe site of deposition are discussed.2008040379丹 麦 始 新 统 最 下 部 豆 娘 的 首 次 发 现 , 及 对 一个 新 的 亚 科 ( 蜻 蜓 目 , 均 翅 亚 目 :Dysagrionidae) 的 描 述 = The first Damselfliesfrom the Lowermost Eocene of Denmark, with adescription of a new subfamily (Odonata, Zygoptera:Dysagrionidae).
