Hispaniolan Hemilophini (Coleoptera,Cerambycidae, Lamiinae)

The Tribe Hemilophini (Lamiinae) is reviewed for Hispaniola and an identification key is provided. Fifteen species are now known from the island, including one new species of Adesmus (Adesmus fortunei from Pedernales and La Vega Provinces, Dominican Republic), one new species of Oedudes (Oedudes anulatus from Peravia and La Vega Provinces, Dominican Republic), and five new species of Calocosmus (Calocosmus contortus from San Cristóbal Province, Calocosmus punctatus from Peravia Province, Calocosmus rawlinsi from Elías Piña Province, Calocosmus robustus from La Vega Province, and Calocosmus thonalmus from La Altagracia Province, all in the Dominican Republic). Oedudes and Adesmus are new island and country records for Hispaniola and Dominican Republic, respectively. Calocosmus holosericeus Gahan is a new synonym of Calocosmus janus Bates. In addition to the new species, five new country records and four new island records are presented for Calocosmus.     

Dinoflagellate cysts,Acritarchs and Tasmanitids from the uppermost Callovian of England and Scotland: With a reconsideration of the “xanthidium pilosum” problem

Four assemblages of fossil organic-walled microphytoplankton from the Upper Callovian (Lamberti Zone), three from England and one from Scotland, are described. They comprise at least 50 species of dinoflagellate cysts, 18 species of acritarchs and 2 species of tasmanitids. After a review of the «Xanthidium pilosum problem, a revised diagnosis is proposed for Sentusidinium pilosum (Ehrenberg) and three new species, Sentusidinium creberbarbatum, S. sparsibarbatum and S. erythrocomum are proposed. The new family name Scriniodiniaceae is substituted for the now invalid family name Endoscriniaceae. The new genus Escharisphaeridia is proposed to contain two existing species, E. pococki (Sarjeant) and E. dictydia (Sarjeant). The present content of the genus Compositosphaeridium is examined; the new combination C. polonicum (Górka) is proposed and a new species, C. bulgaricum, is erected. One further new species of dinoflagellate cyst, Prolixosphaeridium anasillum, is proposed. The new term «peniplate is proposed for paraplates whose boundaries are penitabular in situation.One new species of acritarch, Solisphaeridium?rhachos, is described and the new combination Polygonium aster (Sarjeant) is proposed. Evidence for reworking of some of the species of Micrhystridium present in the Hackness Rock assemblage is noted, though it is considered that the majority of species in that assemblage are indigenous. It is considered that all four assemblages are derived from a single phytoplankton province, the differences between them resulting from environmental factors such as water depth or distance from a shoreline.     

A new genus and species from Borneo and a new species from Java and Sumatra of Cicadini (Hemiptera: Cicadidae)

A new cicada genus and species, Minilomia triquetra, gen. and sp. nov., is described from Borneo. The new genus Minilomia is closely allied to Platylomia Stål and is placed in the subtribe Dundubiina of the tribe Cicadini. Another new cicada species, Pomponia brevicaudata, sp. nov. (subtribe Psithyristriina), is described from Java and Sumatra. The new species belongs to the Pomponia linearis species group and the P. linearis species complex but is distinguished from its congeners by the unusually short male abdomen.     

New and poorly known acrotretid brachiopods (Class Lingulata) from the Cedaria-Crepicephalus zone (late Middle Cambrian) of the Great Basin, USA

Seven new late Middle Cambrian (Cedaria-Crepicephalus zone) acrotretid species are described from the Great Basin, USA. The species belong to five genera of which Lensotreta is new. The following new species are described: Anabolotreta? glabra, Anabolotreta mogota, Canthylotreta crista, Dactylotreta elegantula, Lensotreta perplexa, Opisthotreta transversa, and Opisthotreta indistincta. The shell structure of Canthylotreta is described for the first time based on new material of the type species Canthylotreta marjumensis and of the new species C. crista. The shell of Canthylotreta includes two types of shell fabric, camerate and columnar. Moreover, parts of the shell show transitional textures, supporting the view that the camerate shell structure may has originated from a columnar fabric. Picnotreta lophocracenta Robson and Pratt, 2001, recently described from western Newfoundland, is also described from the new occurrence in the Great Basin.     

A new species and two new records of Minicopenaeon Bourdon, 1981 (Crustacea: Isopoda: Bopyridae) from China

Three species of the parasitic isopod genus Minicopenaeon Bourdon, 1981 (Crustacea: Isopoda: Bopyridae) are reported from China, one new to science and two new records from mainland China. Minicopenaeon crosnieri (Bourdon, 1979) formerly known from Madagascar, the Philippines and Taiwan, is recorded from Zhejiang province. Minicopenaeon intermedium Bourdon, 1981 previously recorded from the Philippines and Japan, is recorded from China for the first time. The new species Minicopenaeon liuruiyui n. sp. is recorded from the East and South China Seas. As with other species of the genus, females of the new species have rudimentary coxal plates on the second pereomeres on the short side. The new species can be distinguished from other species by the presence of a widely open brood pouch, head with bilobate anterior edge and median concave groove, and male head with curved posterior margin of the pleon. A key to species of Minicopenaeon is provided and the subspecies M. intermedium curvatum Bourdon, 1981 is synonymised with M. intermedium Bourdon, 1981. Metapenaeopsis philippii (Bate, 1881) and M. coniger (Wood-Mason, 1891) are newly recorded as host species for bopyrids.     

A new genus of metalmark moths (Lepidoptera,Choreutidae) with Afrotropical and Australasian?distribution

Niveas Rota, new genus, and its two new species, N. agassizi Rota, new species, and N. kone Rota, new species, are described and illustrated. Niveas is assigned to the subfamily Choreutinae based on morphological and molecular data. Niveas agassizi is currently known only from Kenya and only from female specimens. Niveas kone has been found on the Solomon Islands and in Papua New Guinea (PNG). In PNG, larvae of this species have been reared from several species of Ficus (Moraceae). The two species are superficially quite dissimilar from each other. However, they share features in wing pattern and venation, as well as female genitalia, and the molecular data strongly support the monophyly of Niveas.     

A new genus of soft coral (Cnidaria,Octocorallia) from the Republic of Congo (Pointe-Noire Region)

A new genus of soft coral from the Republic of Congo is described, Complexum gen. n. Nine West African octocoral species previously described in the genus Alcyonium by Tixier-Durivault (1955) are referred to this new genus, and a new species is described and figured, Complexum pusillum sp. n. The new species is characterized by having encrusting growth form and abundant spiny clubs in the surface of the polyparium. It colonizes shallow calcareous rocky banks (5 to 20 m depth) existing in coastal water of the region of Pointe-Noire. Based on molecular phylogeny this new genus is well separated from Alcyonium species.     

Micarea viridileprosa sp. nov., an overlooked lichen species from Western Europe

Abstract:A new lichen species, Micarea viridileprosa, is described from western Europe, where it is locally very common. This species, which has previously been much overlooked, is corticolous, lignicolous and terricolous and is usually found sterile. Some specimens of the new species were formerly included in Micarea prasina. The new combination Micarea levicula (Nyl.) Coppins is made for Lecidea levicula Nyl. from Cuba.     

Erysiphe havrylenkoana and E. prunastri var. japonica: a new species and a new variety of Erysiphe sect. Uncinula (Erysiphaceae, Ascomycota)

A new species and a new variety of Erysiphe sect. Uncinula are described and illustrated. Erysiphe havrylenkoana is a new species found on Nothofagus alpina and N. obliqua in Argentina, and E. prunastri var. japonica is a new variety collected on Prunus maximowiczii in Japan. Erysiphe havrylenkoana differs from E. nothofagi, E. patagoniaca and E. magellanica in having unique helicoid appendages, brownish from the base to the beginning of helicoid part, spirally twisted at the center and straight or not spiral at the upper part with uncinate to circinate tip. The phylogenetic analyses of rDNA sequences clearly showed that the spiral pattern of helicoid appendages is an important morphological character to delimit species among Nothofagus powdery mildews. Erysiphe prunastri var. japonica is distinct from E. prunastri var. prunastri parasitizing hitherto Prunus species from East-Central Asia to Europe by having mainly eight asci per chasmothecium and smooth, rarely septate appendages.     

Review of the green lacewing genus Chrysacanthia Lacroix with a new species from Nigeria (Neuroptera,Chrysopidae)

The genus Chrysacanthia Lacroix (Chrysopidae: Belonopterygini) is reviewed and a new species is described from Nigeria. With the addition of the new species described herein, the genus contains four Old World species known from Madagascar, Nigeria, India, Thailand and China.     

Novel method for determination of phenol degradation kinetics

In this study, we proposed a new method for estimating biokinetic parameters in phenol degradation kinetics. The new method relies on the new formulation of q–S relation where degradation rate q is calculated from the changes of substrate concentration S for each time segment during the course of entire degradation, while in the conventional method q is obtained from the slope of the straight line that is given as substrate concentration changes with time in a semi-logarithmic scale. Thus, this new method provided more data points than the conventional method. The q–S relations obtained from the new method and the conventional method were fitted with three inhibitory kinetic models of Haldane, Yano and Edwards. Simulation of degradation profile with each kinetic model and comparison with the observed profile revealed that the new method offered a better prediction with Edwards model as the best inhibitory model.     

One new and seven newly recorded Callichromatini species from China (Coleoptera,?Cerambycidae,?Cerambycinae)

One new species, Schwarzerium yunnanum sp. n. is described from Yunnan Province, China. And a new subgenus Rugosochroma subgen. n. is erected for it. Additionally, Seven species of the tribe Callichromatini are newly recorded from China: Aphrodisium niisatoi Vives & Bentanachs, 2007, Aphrodisium tricoloripes Pic, 1925, Chelidonium violaceimembris Gressitt & Rondon, 1970 (new from Vietnam too), Chloridolum grossepunctatum Gressitt & Rondon, 1970 (new from Vietnam too), Chloridolum semipunctatum Gressit & Rondon 1970, Embrikstrandia vivesi Bentanachs, 2005 and Laosaphrodisium subplicatum (Pic, 1937).     

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.     

Early Tithonian entactinarian Radiolaria from the Solnhofen area (southern Germany). Part I

The article describes part of the Entactinaria radiolarians from a very rich and well-preserved radiolarian assemblage extracted from a lower Tithonian sample (Mue 22) collected from the Mühlheim Member of the Mörnsheim Formation of southern Germany. With a single exception (genus Odoghertites nov. gen.), all other Entactinaria described are of primitive type, that is their initial spicules are not differentiated into an apical and a basal group and are not connected by arches to form a heteropolar “microsphere”. They have been assigned to five families, four of which are new (Isometractiniidae, Triumbraculidae, Hollandocachoniidae, Odoghertitidae), 10 new genera (Isometractinia, Triumbraculum, Tardentactinia, Lententactinia, Hollandocachonia, Sphaerentofurca, Stylentofurca, Zuegelifurca, Spongentofurca, Odoghertites), and 19 new species. One of the new species comes from the lower Bajocian of Oregon. A new skeletal structural term, support structure, is introduced as a special type of connection between the primary spines and the macrosphere or cortical shell.     

A new species of the genus Arhynchite (Annelida,Echiura) from sandy flats of Japan,previously referred?to as Thalassema owstoni Ikeda, 1904

A new echiuran, Arhynchite hayaoi sp. n., is described from newly collected specimens from sandy flats of the Seto Inland Sea, Japan, together with many museum specimens, including those once identified as Thalassema owstoni Ikeda, 1904 or Arhynchite arhynchite (Ikeda, 1924). The new species is clearly distinguishable from its congeners by the smooth margin of gonostomal lips and lack of rectal caecum. Brief references are also made to the morphological distinction between the new species and Thalassema owstoni, originally described from the deep bottom on the Japanese Pacific coast.     

Antrodia hyalina, a new polypore from Russia, and A. leucaena, new to Europe

A new polypore species, Antrodia hyalina, is described from Russia. It is morphologically similar to Antrodia pulvinascens, but differs in having annual, thinner and softer basidiocarps, solid skeletal hyphae, and cylindrical spores. Antrodia leucaena, originally described from China, is reported as new from Finland and Russia on Populus tremula. Antrodia wangii is regarded as a synonym of A. bondartsevae.     

Three new records of powdery mildews found in Mexico with one genus and one new species proposed

Cystotheca lanestris on the new host Quercus canbyi, Microidium bauhiniicola on the new host Bauhinia macranthera and an undescribed species of Phyllactinia on Mimosa aculeaticarpa have recently been collected in Mexico. Analyses of morphological traits and molecular sequence data led to identifications of the causal agents of the powdery mildew diseases involved. Microidium bauhiniicola, hitherto only known from Argentina and Brazil, is new to Mexico. The phylogenetic analysis revealed an isolated position distant from Microidium indicating an undescribed genus, which is introduced as Bulbomicroidium gen. nov. Sequences derived from a Mexican specimen of C. lanestris on Quercus canbyi agree completely with other North American sequences, but differ from sequences retrieved from Asian collections, suggesting that C. lanestris in Asia is not conspecific with C. lanestris s. str. in North America. A new species of Phyllactinia on Mimosa malacophylla is morphologically similar to P. dalbergiae but readily distinguishable by differences in the asexual morph. Based on morphological peculiarities and results of molecular sequence analyses, this species is described as Phyllactinia mimosae sp. nov.
