Baylisascaris potosis n. sp., a new ascarid nematode isolated from captive kinkajou,Potos flavus,from the Cooperative Republic of Guyana

We describe a new nematode species, Baylisascaris potosis n. sp., isolated from captive kinkajou, Potos flavus, from the Cooperative Republic of Guyana. The nematode was found in fecal specimens, identified morphologically, and confirmed genetically. The new species is similar to Baylisascaris procyonis, Baylisascaris columnaris, and other Baylisascaris species, but is distinguished by the position of the male phasmidial pole. Nuclear and mitochondrial DNA sequence analyses confirmed that the new species is phylogenetically distinct from all the members of the genus Baylisascaris, and groups with B. procyonis and B. columnaris. This nematode is the 10th species assigned to the genus Baylisascaris.

Trematodes Recovered in the Small Intestine of Stray Cats in the Republic of Korea

In 2005, we reported the infection status of 438 stray cats with various species of intestinal helminths, including nematodes (4 species), trematodes (23 species), and cestodes (5 species) in the Republic of Korea. However, morphologic details of each helminth species have not been provided. In the present study, we intended to describe morphologic details of 13 trematode species which were either new fauna of cats (10 species) or new fauna of not only cats but also all animal hosts (3 species). The worms were fixed in 10% neutral buffered formalin under a cover slip pressure, stained with Semichon''s acetocarmine, and then observed using a light microscope equipped with a micrometer. The 13 subjected species included members of the Heterophyidae (Stellantchasmus falcatus, Stictodora fuscata, Stictodora lari, Centrocestus armatus, Procerovum varium, and Cryptocotyle concava), Echinostomatidae (Echinostoma hortense, Echinostoma revolutum, Echinochasmus japonicus, and Stephanoprora sp.), Diplostomidae (Neodiplostomum seoulense), Plagiorchiidae (Plagiorchis muris), and Dicrocoeliidae (Eurytrema pancreaticum). By the present study, Cryptocotyle sp. and Neodiplostomum sp. recored in our previous study were identified as C. concava and N. seoulense, respectively. Three species, P. varium, C. concava, and Stephanoprora sp., are new trematode fauna in Korea.

A key to the species of Cannomois is provided, as well as a table comparing the characters of the three species in Nevillea. For all new species, notes on the affinities of the species and their habitats are provided. Two new combinations, Cannomois primosii (Pillans) H.P. Linder and Cannomois robusta (Kunth) H.P. Linder, are made.     

A new species of the Rhinella margaritifera species group (Anura,Bufonidae) from the montane forest of the Selva Central,Peru

We describe a new species of the bufonid toad genus Rhinella from transition montane forest of the buffer zones of the Yanachaga-Chemillén National Park and the Pui Pui Protected Forest (eastern slopes of Andes, Selva Central, Peru). The new species belongs to the Rhinella margaritifera species group (confirmed by mtDNA data) and differs from all its members by the absence of tympanic membrane and tympanic annulus. It is characterized by medium size (SVL 57.5–65.5 mm, n = 5), moderately developed cranial crests, absence of neural crest of vertebrae, absence of bone protrusion at angle of jaw, presence of lateral rows of enlarged tubercles, and absence of subgular vocal sac and vocal slits in males. In addition, based on the molecular phylogenetic analyses of selected Rhinella species we propose the monophylum containing R. chavin, R. festae, R. macrorhina, R. manu, R. nesiotes, R. rostrata, and R. yanachaga as a new species group under the name Rhinella festae species group.

Leaf essential oil composition of 10 species of Ocotea (Lauraceae) from Monteverde,Costa Rica

The leaf essential oils of 10 species of Ocotea (Lauraceae) from Monteverde, Costa Rica (Ocotea floribunda, Ocotea holdridgeana, Ocotea meziana, Ocotea sinuata, Ocotea tonduzii, Ocotea valeriana, Ocotea veraguensis, Ocotea whitei, and two undescribed species, Ocotea new species “los llanos”, and Ocotea new species “small leaf”) have been obtained by hydrodistillation and analyzed by GC–MS in order to discern the differences and similarities between the volatile chemical compositions of these species. The principal common constituents of the 10 species of Ocotea were α-pinene, β-pinene, β-caryophyllene, and germacrene-D.     

Six new species of Pythiogeton in Taiwan,with an account of the molecular phylogeny of this genus

Pythiogeton is a little-studied genus of pythialean Oomycete. The genus is characterized by producing its zoospores outside of the sporangium within an apparently naked protoplasmic mass, which formed from a discharge tube-vesicle complex. A total of nine morphologically distinct Pythiogeton species were identified, of which six were new species (Pythiogeton abundans, Pythiogeton microzoosporum, Pythiogeton oblongilobum, Pythiogeton paucisporum, Pythiogeton proliferatum, and Pythiogeton puliensis). A phylogenetic analysis based on internal transcribed spacer sequences revealed that all isolates of Pythiogeton formed a highly supported clade, nested within the wider clade of Pythium species. Each newly recognized Pythiogeton species that was established on the basis of morphological characters was found to occur in a well-supported subgroup within the Pythiogeton clade, confirming their assignment to new species. Pythiogeton shares a common ancestor with the monophyletic group of Pythium species that have predominantly filamentous sporangia rather than with the separate clade of Pythium species that have predominantly globose or ovoid sporangia. This study confirms that Pythium is an extremely heterogenous and polyphyletic genus containing a number of distinct clades of species, including Pythiogeton, which possess morphologically distinguishable characters. A synoptic key to all the described Pythiogeton species is provided.     

Characterization and virulence of entomopathogenic fungi from sunn pests in Turkey

The sunn pests (Eurygaster spp.) which are important pests of wheat and barley, can lead to 100% yield loss in the case of an epidemic. This study was conducted to characterize the entomopathogenic fungi, obtained from the sunn pests collected from different overwintering areas of Turkey and determine their pathogenicity. Seventeen Beauveria pseudobassiana, 12 Beauveria bassiana, 16 Cordyceps farinosa, 1 Purpureocillium lilacinum, and 2 Clonostachys rosea species were identified. Pathogenicity tests were performed with three B. pseudobassiana, two B. bassiana, four C. farinosa, and one P. lilacinum isolates. B. pseudobassiana isolates BB34 and AF4 caused 100% death on the 9th day, and another B. pseudobassiana isolate E512 caused 100% death on the 12th day. C. farinosa isolate KOKA2 caused 95.8% death on the 15th day. Ultimately, B. pseudobassiana was determined to be the most prevalent and virulent species on sunn pests.     

A new species of Scolecobasidium associated with the sooty blotch and flyspeck complex on banana from China

Sooty blotch and flyspeck is caused by a complex of epiphytic fungi on diverse hosts. A fungus morphologically similar to Scolecobasidium humicola was isolated from a banana fruit exhibiting SBFS signs in Hainan, China. ITS and LSU sequences of rDNA corroborated that it was a Scolecobasidium species. The results of LSU rDNA analysis support the interpretation that Ochroconis is synonymous with Scolecobasidium. Five new combinations, S. anomalum, S. calidifluminale, S. gallopavum, S. gamsii, and S. lascauxense, were proposed. A new species, S. musae, was described based on morphological characteristics and sequence comparison with previous species.     

Unusual assemblages of Late Cretaceous silicoflagellates from the Canadian Archipelago

Devon and Ellef Ringnes islands in the Canadian Arctic Archipelago contain well-preserved Santonian through early Campanian silicoflagellates. These occur in three unusual assemblages, which comprise three biostratigraphic zones. The oldest, the Vallacerta tumidula Partial Range Zone of Santonian age, contains an extremely variable microflora that includes species of the poorly-known genus Variramus, two new species of Cornua, and a new genus Umpiocha. The Schulzyocha ruppelii Range Zone of early Campanian age includes several species of the new genus Schulzyocha, reflecting quadrate silicoflagellate skeletal morphologies that lack a basal structure. The youngest assemblage includes the poorly-known species Cornua trifurcata, the nominative taxon of the C. trifurcata Partial Range Zone (proposed by McCartney et al., in press c; emended herein), which allows a correlation with a silicoflagellate-bearing sequence from the Horton River area, Northwest Territories of Canada. This report presents information on 24 silicoflagellate taxa, proposes 2 new genera, Schulzyocha and Umpiocha, and describes 13 new species and 1 new combination. All of these new taxa disappear by the top of the Campanian Cornua trifurcata Partial Range Zone. These assemblages reveal a new history of silicoflagellate evolution prior to the late Campanian, the period from which most of our prior knowledge about Cretaceous silicoflagellates was derived. The assemblages show progressive change from skeletons with highly variable morphologies to more stable silicoflagellate skeletal geometry. Two important Corbisema species, C. apiculata and C. archangelskiana, appear to be derived from separate lines within Cornua in the latest Santonian and early Campanian. The important Cretaceous genus Lyramula makes its first appearance at the beginning of the Campanian.     

Materials on the flora of Bacillariophyta in rivers of the white sea basin in the Republic of Karelia

A total of 290 species and varieties of Bacillariophyta including 32 that were new for the flora of Karelia and 18 that were new for the flora of Russia, have been recorded in phytoplankton in nine rivers of the White Sea basin. The genera Aulacoseira, Pinnularia, Eunotia, and Navicula s. l. are the richest in taxonomy. The maximum species diversity was recorded in the Suma (73), Kolezhma (91), and Chirko-Kem (146) rivers. The following species are the most widespread in the rivers that were under study here: A. ambigua, A. subarctica, A. subborealis, {tiA. tenella}, Asterionella formosa, and Tabellaria flocculosa.     

Studies in the cyperaceae of Thailand

Described as new areCarex subinclinata andC. thailandica, both belonging to the sectionIndicae, andC. speciosa ssp.latifolia of the sectionRadicales. Two new combinations proposed areCarex helferi ssp.mapanifolia, andC. speciosa ssp.platyrhina.     

A new species of the genus Trematosphaeria from China

A new species of the genus Trematosphaeria was isolated and identified from the soil in Jiuzhaigou Nature Reserve, southwestern China. The new taxon was studied based on morphological characters and phylogenetic analyses of three nuclear loci, i.e., the internal transcribed spacer rDNA operon (ITS), and large and small subunit nuclear ribosomal DNA (nuc28S rDNA, nuc18S rDNA). The analyzed Trematosphaeria species were clustered in several clades within the Pleosporales and the genus was shown to be polyphyletic. The new species is introduced as Trematosphaeria terricola, and it is characterized by short-papillate ascomata with suborbicular ostiolum, 3-septate, cinnamon-brown, fusiform ascospores with narrowly rounded ends, verruculose at maturity. Trematosphaeria terricola is compared with morphologically similar species T. confusa, T. mangrovis, and T. pertusa, which differ from the former species in the number of septa, and the shape and size of the ascospores with or without a sheath. This is the first report of a Trematosphaeria isolate from alpine soil in China.     

A new species of Labidocera (Copepoda,Calanoida, Pontellidae) collected from Okinawa,southwestern Japan,with establishment of five Indo-West Pacific species groups in the L. detruncata species complex

Labidocera churaumi sp. n. is described from Okinawa, southwestern Japan. The female of the new species differs from other congeners in genital compound somite with right postero-lateral and left antero-lateral processes. The male is distinguished from other congeners by the structure of the fifth leg. This new species is assigned to a newly proposed species group, the Labidocera madurae species group, within the Labidocera detruncata species complex. In this species complex five Indo-West Pacific species groups are recognized (cervi, detruncata, gangetica, madurae, and pavo) and defined on the basis of difference in sexual dimorphism.     

Cercosporoid hyphomycetes on malpighiaceous hosts from the Brazilian Cerrado: New Passalora and Pseudocercospora species on hosts of the genus Banisteriopsis

On the taxonomic status of some Glyptodontidae (Mammalia,Xenarthra, Cingulata) from the Pleistocene of South America

The anatomical and taxonomic knowledge of some groups of Glyptodontidae (Mammalia, Cingulata) is still very poor. In addition, a strict typological/morphological taxonomic criterion was used in recognizing many taxa, especially during the second half of the 19th century and the first of the 20th century. This particular situation resulted in a clear overestimation diversity, mainly with respect to the South American glyptodonts. In this scenario, this paper analyzes the taxonomic status of some Glyptodontinae through a precise comparative study with well characterized taxa. The main results show that the genera Pseudothoracophorus Castellanos (P. depressus) and Chlamydotherium Lund, one species of the genus “Boreostracon” Simpson (B. corondanus), and one species of the genus Glyptodon Owen (G. falkneri), actually represents juvenile specimens referable to Glyptodon Owen; the genus Neothoracophorus Ameghino (N. elevatus) could be related either to Glyptodon Owen or Glyptotherium Osborn. Another species, Heteroglyptodon genuarioi, presents an almost identical morphology compared with the recognized species of Glyptodon (e.g. G. munizi and G. reticulatus). In this sense, the diagnostic characters described for Glyptodon perforatus Ameghino, a taxon with biostratigraphic relevance since it is characteristic of the Lujanian Age/Stage (late Pleistocene-early Holocene), are also present in other species of Glyptodon, especially G. reticulatus and G. clavipes, very frequent taxa in southern South America.
