Addition and re-examination of Japanese species belonging to the genus <Emphasis Type="Italic">Cercospora</Emphasis> and allied genera. X: newly recorded species from Japan (5)

Cercospora yakushimensis is proposed as a new combination, Pseudocercospora yakushimensis comb. nov., and the morphology of the species is characterized from herbarium specimens, including the type. Six additional species belonging to the genus Cercospora and its allied genera are newly added to the Japanese mycoflora, namely, Cercospora dioscoreae-pyrifoliae on Dioscorea tokoro, Pseudocercospora catalpigena on Catalpa ovata, Pseudocercospora coriariae on Coriaria japonica, Pseudocercospora lythri on two species of Lythrum, Pseudocercospora pteroceltidis on Celtis boninensis, and Passalora puncta on Foeniculum vulgare.     

Four new species of <Emphasis Type="Italic">Phyllosticta</Emphasis>, one new species of <Emphasis Type="Italic">Pseudocercospora</Emphasis>, and one new combination in <Emphasis Type="Italic">Passalora</Emphasis> from Japan

During a survey of plant-inhabiting fungi in a botanical garden in Japan, some noteworthy fungi were collected from leaf spots of some herbal and arboreal plants. Among them, five new species are described, namely: Phyllosticta. ardisiicola on Ardisia crenata, Phy. aspidistricola on Aspidistra elatior, Phy. kerriae on Kerria japonica, Phy. fallopiae on Fallopia japonica, and Pseudocercospora davidiicola on Davidia involucrata. Passalora pyrrosiae, a new combination for Pseudocercospora pyrrosiae on Pyrrosia lingua, is proposed based on its morphological characteristics designating the neotype specimen.     

New species of the genus <Emphasis Type="Italic">Macclintockia</Emphasis> (Angiosperms) from the Campanian of the Ugol’naya Bay (Northeastern Russia)

New species of angiosperms are described as members of the genus Macclintockia from the Ugol’naya Bay area, in northeastern Russia: M. barykovensis Moiseeva, sp. nov., M. gigantea Moiseeva, sp. nov., and M. terranea Moiseeva et Herman, sp. nov. Leaves of this genus are considerably variable, which hampers differentiation between particular species. The study of new material has allowed the author to trace the morphological variability of these species and revised on this ground the composition of the species M. ochotica Vachr. et Herman and M. beringiana Herman. The composition of Macclintockia is discussed, as well as its occurrence during the Late Cretaceous.

A new species of the genus <Emphasis Type="Italic">Caulophilus</Emphasis> Woll. (Coleoptera: Curculionidae: Cossoninae) from the Rovno amber

Caulophilus zherikhini, sp. nov. (Curculionidae: Cossoninae) is described from the Late Eocene Rovno amber. The new species is distinguished from all known species of the genus by its longer rostrum. It is especially similar to C. falini Davis et Engel, 2007 from Dominican amber, from which it probably differs also in the more strongly curved rostrum, less flattened body, longer and narrower profemur, and shorter elytral setae.     

Specificity of <Emphasis Type="Italic">Anagyrus</Emphasis> sp. nov. nr. <Emphasis Type="Italic">sinope</Emphasis> and <Emphasis Type="Italic">Leptomastix dactylopii</Emphasis> for six mealybug species

In order to understand better non-target effect and potential uses, the host specificity of two parasitoid species (Anagyrus sp. nov. nr. sinope Noyes & Menezes and Leptomastix dactylopii Howard) (both Hymenoptera: Encyrtidae) for six mealybug species [Ferrisia virgata (Cockerell), Phenacoccus madeirensis Green, Phenacoccus solani Ferris, Planococcus citri (Risso),Pseudococcus longispinus (Targioni-Tozzetti) and Pseudococcus viburni (Signoret)] (all Hemiptera: Pseudococcidae) was studied through behavioral observations and laboratory rearing. The selected mealybug species represent major subfamilies and tribes of Pseudococcidae. Except for F. virgata, all mealybug species induced examinations by Anagyrus sp. nov. nr. sinope and L. dactylopii. Anagyrus sp. nov. nr. sinope was specific to P. madeirensis, which was the only mealybug species selected for oviposition and suitable for complete development of the parasitoid. No encapsulation of Anagyrus sp. nov. nr. sinope in P. madeirensis was observed. Leptomastix dactylopii accepted multiple species for oviposition, with the ranking of species preference as P. citri > P. viburni > P. longispinus > P. solani > P. madeirensis. Only P. citri, P. longispinus and P. viburni supported the development of L. dactylopii. Parasitoids developing in P. longispinus and P. viburni suffered from high encapsulation rates, while no encapsulation was observed when developing in P. citri. The results of this study suggest that Anagyrus sp. nov. nr. sinope is highly host specific. Leptomastix dactylopii, on the other hand, has a wider host range. The use of Anagyrus sp. nov. nr. sinope in a mealybug biological control program is limited to P. madeirensis and L. dactylopii to P. citri. The results presented in this study also lead us to question the accuracy of the reported host range of L. dactylopii, which include all six mealybug species tested.     

Dinoflagellate cyst biostratigraphy of the Coniacian–Santonian (Upper Cretaceous): New data from the English Chalk

Results are presented here for the first chalk-based, high-resolution quantitative study of organic-walled dinoflagellate cysts (dinocysts) from the entire Coniacian–Santonian Chalk successions in east Kent and on the Isle of Wight. The lithostratigraphy and dinocyst records (137 taxa) of seven sections are presented, and the stratigraphic ranges of taxa are constrained relative to stage and zonal boundaries, located using extensive macrofossil data. Results are integrated with a previous complementary study of the Isle of Wight Santonian to test and refine existing dinocyst bioevent schemes. Sixteen dinocyst events are proposed as a sequence of biostratigraphic datum levels for the lower Coniacian to uppermost Santonian which, based on average sedimentation rates, represent an average temporal resolution of around 360 kyr. The event stratigraphy forms a basis for the first high-resolution correlation study of quantitative dinocyst data from the Upper Cretaceous of NW Europe. A new genus Culversphaera Prince, Jarvis, Pearce et Tocher gen. nov. is proposed with the new combination Culversphaera velata Prince, Jarvis, Pearce et Tocher gen. et comb. nov. Five new species: Ellipsodinium membraniferum Prince, Jarvis, Pearce et Tocher sp. nov., Senoniasphaera macroreticulata Prince, Jarvis, Pearce et Tocher sp. nov., Senoniasphaera whitenessii Prince, Jarvis, Pearce et Tocher sp. nov., Xenascus spinatus Prince, Jarvis, Pearce et Tocher sp. nov. and X. yunii sp. nov., and the new subspecies S. protrusa congrensa Prince, Jarvis, Pearce et Tocher subsp. nov. are described.

皖北地区寒武系芙蓉统炒米店组中上部的索克虫类三叶虫*

塔里木盆地塔中台地奥陶系海百合茎化石丰富。本文通过研究塔中35井上奥陶统良里塔格组和桑塔木组岩芯中的海百合与其共生生物的关系, 讨论了海百合化石的古生态。在塔中35井上奥陶统取芯中识别出7种海百合茎类型: 圆圆茎、星星茎、星圆茎、椭圆圆茎、星椭圆茎、圆角星星茎和不规则星茎, 根据茎板形态划分为五射茎板组(Pentameri)、椭圆茎板组(Elliptici)、圆茎板组(Cyclici)、特殊茎板组(Varii)四种组合类型; 统计了海百合茎化石各种切面的大小和百分含量; 结合岩性分析了每段地层的沉积环境。研究发现, 在局限泻湖环境下, 蓝细菌–四分珊瑚为主的生物组合中不见海百合化石碎片; 仅见腹足类和介壳类化石的细砂屑滩中, 偶见细小的海百合茎化石; 在开阔海环境中, 海百合广泛与苔藓虫、管孔藻、粗枝藻等共生。在海百合–苔藓虫组合中, 海百合茎板的类型最丰富多样, 五射茎板组、椭圆茎板组、圆茎板组、特殊茎板组等四种茎板组合类型都存在; 在管孔藻–海百合组合中, 海百合茎板主要为圆茎板类型, 粗大、密集, 海百合茎碎片含量最高; 在海百合–粗枝藻组合中, 海百合茎板的数量减少、大小变小, 但茎板的类型比较丰富, 四种茎板组合类型都有。由此认为, 塔中台地上奥陶统沉积期, 海百合生长的首选环境为开阔台地, 并受水动力能量和水体清洁度控制: 水动力能量高, 水体清洁, 海百合繁盛; 水动力能量低, 水体动荡浑浊, 海百合可以生存; 水动力能量低、较为动荡、微生物席发育的环境, 不利于海百合生存。
