Morphological studies on two marine colepid ciliates from Qingdao, China, Nolandia orientalis spec. nov. and Pinacocoleps similis (Kahl, 1933) comb. nov. (Ciliophora, Colepidae)

Recent studies have revealed that the “lower” marine ciliates are far more diverse than previously suspected. During a survey on the ciliate fauna in coastal waters of Qingdao, northern China, we have isolated about 30 new or poorly known taxa. In the present study two colepid species are investigated, Nolandia orientalis spec. nov. and Pinacocoleps similis (Kahl, 1933) comb. nov. (basionym: Coleps similis Kahl, 1933). Their morphology and infraciliature are documented based on living observations and silver impregnations. The new species Nolandia orientalis differs from the type species N. nolandi mainly in the structure of tier plates. The structure of the tier plates was also the basis for transferring Coleps similis Kahl, 1933 to the genus Pinacocoleps and for three further new combinations: Pinacocoleps heteracanthus (Noland, 1937) comb. nov. (basionym: Coleps heteracanthus Noland, 1937), P. spiralis (Noland, 1937) comb. nov. (basionym Coleps spiralis Noland, 1937) and Pinacocoleps arenarius (Bock, 1952) comb. nov. (basionym: Coleps arenarius Bock, 1952).     

A new genus Thubdora Park,gen. nov. and seven new species of the subfamily Torodorinae (Lepidoptera,Lecithoceridae) from Cameroon and Rep. of Congo,Africa

Based on the material collected from Cameroon in 1913–1918 and Congo in 1993 which are preserved in the Carnegie Museum of Natural History, Pittsburgh, USA, a new genus Thubdora Park, gen. nov. and seven new species of the subfamily Torodorinae (Lecithoceridae) are described. They are Torodora efulenensis sp. nov., Dragmatucha hispidula sp. nov.; and five species of Thubdora: T. acutalis sp. nov., T. bilobella sp. nov., T. aciphalla sp. nov., T. ambliodes sp. nov., and T. cameroona sp. nov. In addition, six species of Lecithocera Herrich-Shäffer described by Viette, 1955, Viette, 1986 and Meyrick, 1931, Meyrick, 1933 are newly transferred to Torodora and its related genera, due to the male genital characters: Idiopteryx adella (Viette, 1955), comb. nov.; Thubdora decavella (Viette, 1955), comb. nov.; Thubdora mocquerysella (Viette, 1955), comb. nov.; Torodora kambanella (Viette, 1986), comb. nov.; Torodora masoalella (Viette, 1955), comb. nov.; Torodora monobyrsa (Meyrick, 1931), comb. nov.; and T. ochrometra (Meyrick, 1933), comb. nov. For the new species, images of adults with their labels and genitalia are provided.     

Two new species of Electra (Bryozoa, Cheilostomata) from the Miocene of the Aquitaine Basin, France

Post-Cretaceous examples of Electridae, a primitive family of cheilostome bryozoans, are poorly represented in the fossil record, probably because of their thinly calcified zooids and preference for nearshore environments. Two new electrid species are here described from the Lower Miocene (Burdigalian) of Pontpourquey, Aquitaine, France: Electra triaurata nov. sp. and Electra aquitanica nov. sp. Both species belong to extant species groups, the E. indica and E. biscuta groups, respectively, that presently occur in the Indo-Pacific; both are the only fossil examples of these species groups. Whereas E. triaurata nov. sp. has uniserial colonies, zooids with porous gymnocysts, three flattened spines and basal windows allowing etching of the substrate to produce the trace fossil Leptichnus, E. aquitanica nov. sp. has multiserial colonies and zooids with a proximal gymnocyst bearing 2 to 5 spines.     

The genus Hormiops Fage, 1933 (Hormuridae,Scorpiones), a palaeoendemic of the South China Sea: Systematics and biogeography

The monotypic genus Hormiops Fage, 1933 is so far only known from two groups of granitic islands off the coasts of Peninsular Malaysia and Vietnam. Examination of newly collected material from both archipelagos and of the type series of Hormiops davidovi Fage, 1933 reveals previously disregarded morphological differences sufficient to assign the Malaysian specimens to a distinct species, described here as Hormiops infulcra sp. nov. An updated diagnosis of the genus, as well as a dichotomic key enabling the determination of Hormiops from its close relatives, Hormurus Thorell, 1876 and Liocheles Sundevall, 1833 are also provided. The phylogenetic position, distribution pattern, and ecology of these insular scorpions suggest that they are palaeoendemics, remnants of a previously more widely distributed lineage. A biogeographical model is proposed for the genus based on these observations and on a synthesis of palaeogeographical and palaeoenvironmental data currently available for Sundaland.     

Vietnamese species of Taumacera viridis–group with a description of new species (Coleoptera: Chrysomelidae: Galerucinae)

The species of Taumacera viridis species–group from Vietnam are revised. Four species are recognized. Taumacera indica (Jacoby, 1889), T. occipitalis (Laboissière, 1933) and T. variceps (Laboissière, 1933), are redescribed. Taumacera phuquoca sp. nov. from Phu Quoc National Park (southern Vietnam) is described. An identification key is provided for all Vietnamese species.www.zoobank.org/urn:lsid:zoobank.org:pub:396862F9-8A47-4101-A27C-CD0625E68FA1.     

A contribution to the revision of the genus Fenestella (Bryozoa) from the lower carboniferous of the east European platform

About 50 species of the genus Fenestella from the Lower Carboniferous of the East European platform are revised. They are shown to belong to the following seven genera: Fenestella, Rectifenestella, Laxifenestella, Exfenestella, Fabifenestella, Alternifenestella, and Ignotifenestella. Diagnoses of the three latter genera are given and 11 species are described, including type species, one of which, A. substricta sp. nov., is new. Lectotypes are selected for the three known species A. major (Nikiforova, 1933), A. minor (Nikiforova, 1933), and A. media (Nikiforova, 1927).     

Description of Hygrobates aloisii sp. nov. from Hong Kong, a new species of Hygrobates (Lurchibates) subgen. nov. (Acari, Hydrachnidia, Hygrobatidae), with data on the parasite-host relationship to the Hong Kong Newt Paramesotriton hongkongensis (Amphibia, Caudata, Salamandridae)

Adults and deutonymphs of a new water mite species of the genus Hygrobates Koch, 1837 (Acari, Hydrachnidia, Hygrobatidae) were found to parasitize the Hong Kong Newt, Paramesotriton hongkongensis Myers and Leviton, 1962 (Amphibia, Caudata, Salamandridae), endemic to Hong Kong and coastal areas of Guangdong Province: Hygrobates aloisii sp. nov. Males and females, as well as deutonymphs and larvae are described. A new subgenus - Lurchibates subgen. nov. - is defined to accommodate the species of the Hygrobates salamandrarum-group. The parasite-host association, infestation rate, attachment sites and the impact of mite infestation on the newts behaviour and body condition are investigated. These ecological aspects of the parasite-host association between freshwater mites and newts are examined for the first time in detail in their natural habitat.     

First record of the genus Leluthia Cameron, 1887 (Hymenoptera: Braconidae,Doryctinae) in the Oriental region with description of two new species from India

The genus Leluthia Cameron, 1887 is recorded for the first time from the Oriental region. Two new species, Leluthia (Euhecabolodes) areola Ranjith et Belokobylskij, sp. nov. and L.(E.) indica Belokobylskij et Ranjith, sp. nov. are described and illustrated from the Indian states Kerala and Goa, respectively. The new species are most similar to the Western Palaearctic Hecabolus hungaricus (Szépligeti, 1900), which is reinstated from its synonymy with Polystenus and transferred to the genus Leluthia Cameron (stat. resurr. and comb. nov.).     

Cortinarius sect. Brunnei (Basidiomycota, Agaricales) in North Europe

The section Brunnei was extensively studied based on material from North Europe. To stabilise the nomenclature we studied the relevant types of taxa included in this section. Phylogenetic relationships and species limits were investigated using rDNA ITS sequences and the results were compared with the morphological data. We recognised 11 species: Cortinarius brunneus, C. clarobrunneus comb. nov., C. coleoptera, C. ectypus, C. gentilis, C. glandicolor (neotypified), C. pseudorubricosus, and four species described as new C. caesiobrunneus, C. albogaudis, C. carabus, and C. cicindela. They are described here and their taxonomy, ecology, distribution, and relationships are discussed. In addition, a key to species of the section Brunnei is provided. A total of 77 new sequences of 11 species are published including nine type sequences. Also the taxonomic assignments of sequences in the public databases belonging to the section Brunnei are revised.     

Siamspinops, a new selenopid spider genus from Southeast Asia (Arachnida, Araneae)

Examination of a collection of selenopid spiders from Southeast Asia resulted in recognition of a new genus, Siamspinops gen. nov., which is erected to accommodate four new Southeast Asian species. Siamspinops spinosissimus sp. nov. (the type species; the male and female are described), S. spinosus sp. nov. (female) and S. allospinosus sp. nov. (female) are recorded from Thailand, S. spinescens sp. nov. (female) from the Malay Peninsula.     

New ancyloceratidae (Ammonoidea) from the Aptian of the Ulyanovsk region,Middle Volga

A new subgenus of Polia, Metallopolia subgen. n., two new species (Polia (Metallopolia) dysgnorima sp. n. and P. (M.) metagnorima sp. n.) from China (Sichuan, Yunnan, Gansu), and a new subspecies, P. (M.) subviolacea kanchenjunga ssp. n. from Nepal and SE Tibet (Sikkim) are described. Habitus, antennae, male and female genitalia of all Metallopolia species are characterised, depicted and compared with the related species.     

Psednotrichia perennis (Asteraceae,Senecioneae): A new species from the Huila plateau,Angola

The genus Psednotrichia (Asteraceae–Senecioneae) is endemic to Angola and currently consists of two annual species, P. xyridopsis (O. Hoffm.) Anderb. & P. O. Karis, and P. newtonii (O. Hoffm.) Anderb. & P. O. Karis. A perennial member of the genus was collected on a recent field trip to Angola, and is here described as P. perennis N. G. Bergh & B. Nord., sp. nov. A key to the three species is provided.     

Taxonomy of the genus Ectopioglossa Perkins from China,with two new species and an updated key to the Oriental species (Hymenoptera: Vespidae: Eumeninae)

A total of five species of the genus Ectopioglossa is reviewed from China, of which two new species are described and illustrated. These two new species are Ectopioglossa trimacula sp. nov. and E. convexa sp. nov., collected from Guangxi and Yunnan, China, respectively. Among other three nomial species, E. sublaevis (Smith, 1857) is new to China. An updated key to the Oriental species is also provided.     

Ants of the tribe Formicini (Hymenoptera,Formicidae) from Late Eocene amber of Europe

The tribe Formicini (Formicinae) from the Late Eocene Baltic, Bitterfeld, Rovno, and Scandinavian ambers is revised. Ants are recorded for the first time from the Bitterfeld and Scandinavian ambers. Two new genera (Cataglyphoides gen. nov. and Conoformica gen. nov.) and six new species (Cataglyphoides intermedius sp. nov., Conoformica bitterfeldiana sp. nov., Formica kutscheri sp. nov., F. palaeopolonica sp. nov., F. radchenkoi sp. nov., F. zherikhini sp. nov.) are described. A new combination, Cataglyphoides constrictus (Mayr, 1868), comb. nov., is established. A lectotype of Camponotus constrictus Mayr, 1868 and a neotype of Formica phaethusa Wheeler, 1915 are designated. Formica clymene Wheeler, 1915 is recognized as a new synonym of F. phaethusa Wheeler, 1915. An identification key for workers of Formicini species from Late Eocene European ambers is provided.     

Mycobiota associated with the ambrosia beetle Scolytodes unipunctatus (Coleoptera: Curculionidae, Scolytinae)

Ambrosia beetles (Coleoptera: Scolytinae) are associated with strictly entomochoric and mutualistic fungi. We studied the mycobiota associated with Scolytodes unipunctatus, ambrosia beetles that infest Cecropia trees in Central America. Isolates were characterized using morphology and rDNA sequences (ITS region, LSU, and SSU rDNA). Four species are described here: Raffaelea scolytodis sp. nov. (Ophiostomatales), Gondwanamyces scolytodis sp. nov., Custingophora cecropiae sp. nov., and Graphium sp. (Microascales). The genus Custingophora is emended to include Knoxdaviesia anamorphs of Gondwanamyces based on uniformity of DNA sequences and phenotype.     

Mesocyclops (Crustacea, Copepoda, Cyclopidae) in the South Pacific islands

Based mainly on recently collected material, we discuss the taxonomy and zoogeography of a (sub)tropical genus, Mesocyclops, in the South Pacific. A new species, Mesocyclops roberti sp. nov. is described from Fiji and the Wallis Islands. New data on the geographic distribution and morphology are reported for Mesocyclops medialis, Mesocyclops woutersi and Mesocyclops aspericornis. Phylogenetic reconstructions coding the intraspecifically variable characters by three different methods (unordered, unscaled and scaled coding) support close relationship of M. roberti with two Australian species (Mesocyclops brooksi and Mesocyclops notius). Both the “unordered” and “scaled” analyses show monophyly of a group composed of Australian (Mesocyclops australiensis, M. brooksi, M. notius, and Mesocyclops pubiventris) and South Pacific (M. medialis and M. roberti sp. nov.) taxa. None of the analyses supports a sister relationship of M. roberti with M. medialis (New Caledonia, Vanuatu), the only other species restricted to South Pacific, which suggests that Mesocyclops invaded the South Pacific from Australia at least twice. The sister relationship of the Australian-South Pacific clade remains unresolved, yet all reconstructions suggest a link with Asian Mesocyclops sp.     

Les premiers Anguilliformes : I. Révision des genres cénomaniens Anguillavus HAY, 1903 et Luenchelys nov. gen.

New specimens from Cenomanian outcrops of Lebanon permit redescribtion of the first eel-like fossil fishes. Anguillavus bathshebaeHay, 1903 becomes synonymous with the type species A. quadripinnisHay, 1903. A new fossil eel with pelvic fins, Anguillavus mazeni nov. sp., is furthermore proposed. In the same way, the revision of Luenchelys minimus nov. gen., nov. sp., reveals some morphological variations at the specific level and a widespread biogeographical repartition which potentially can be important. This whole anatomical revision is a necessary basis for integrating these fossils into the Anguilliformes (Teleostei, Elopomorpha) and gives an idea of the plesiomorphic structural pattern of the order, in which the modern forms are particularly specialised.     

Phylogeny of Phaeomollisia piceae gen. sp. nov.: a dark, septate, conifer-needle endophyte and its relationships to Phialocephala and Acephala

Dark, septate endophytes (DSE) were isolated from roots and needles of dwarf Picea abies and from roots of Vaccinium spp. growing on a permafrost site in the Jura Mountains in Switzerland. Two of the isolates sporulated after incubation for more than one year at 4 °C. One of them was a hitherto undescribed helotialean ascomycete Phaeomollisia piceae gen. sp. nov., the other was a new species of Phialocephala, P. glacialis sp. nov. Both species are closely related to DSE of the Phialocephala fortinii s. lat.-Acephala applanata species complex (PAC) as revealed by phylogenetic analyses of the ITS and 18S rDNA regions. Morphologically dissimilar fungi, such as Vibrissea and Loramyces species, are phylogenetically also closely linked to the new species and the PAC. Cadophora lagerbergii and C. (Phialophora) botulispora are moved to Phialocephala because Phialocephala dimorphospora and P. repens are the closest relatives. Several Mollisia species were closely related to the new species and the PAC according to ITS sequence comparisons. One DSE from needles of Abies alba and one from shoots of Castanea sativa formed Cystodendron anamorphs in culture. Their identical 18S sequences and almost identical ITS sequences indicated Mollisia species as closest relatives, suggesting that Mollisia species are highly euryoecious.     

Cretaceous and Paleogene Bourgueticrinina (Echinodermata,Crinoidea) of the USSR

The theca and the columnals of twenty-two lateCretaceous species of the genus Bourgueticrinus (including two new species), of one species of the genus Democrinus, of four species of the genus Conocrinus (including one new species) and of one species of the genus Paleobathycrinus known from USSR are figured and shortly described. Biometric reconstructions of stems for B. aequalis, B. bellus, B. danicus, B. fischeri and C. tauricus nov. sp. are given. A new index is used to suggest the relative flexibility of stem. Decrease in dimension and flexibility of the arms in several species take place simultaneously with an increase of stem flexibility. This fact seems to be closely related to environmental changes.
