Asparagus beetles of the <Emphasis Type="Italic">Crioceris duodecimpunctata</Emphasis> (Linnaeus, 1758) group (Coleoptera,Chrysomelidae) from Russia and Adjacent Countries

The distribution of Crioceris duodecimpunctata (Linnaeus, 1758) and two related species with their subspecies is defined more precisely. Crioceris orientalis tshingisana Lopatin, 1966, stat. n. and C. hypopsila demokidovi Semenov, 1909, stat. n. are treated as subspecies for the first time. Lectotypes of C. hypopsila Jacobson, 1907, C. demokidovi Semenov, 1909, and C. duodecimpunctata hypolachna Jacobson, 1907 are designated. The male and female genitalia are described and illustrated for all the species considered. A new key to the species of Crioceris without a black sutural stripe is compiled.     

Descriptions of eight new species of <Emphasis Type="Italic">Ligophorus</Emphasis> Euzet &; Suriano, 1977 (Monogenea: Ancyrocephalidae) from Red Sea mullets

Eight new species of Ligophorus Euzet &; Suriano, 1977 (Monogenea: Ancyrocephalidae) are described from two species of mullets from the Red Sea. Ligophorus bykhowskyi n. sp. and L. zhangi n. sp. from Crenimugil crenilabris (Forsskål) differ from other species of the genus in the structure of the male copulatory organ, which has a simple accessory piece and a wide copulatory tube that arises from a large, single-chambered, expanded base. Ligophorus simpliciformis n. sp., L. bipartitus n. sp., L. campanulatus n. sp., L. mamaevi n. sp., L. lebedevi n. sp. and L. surianoae n. sp. from Liza carinata (Valenciennes) are differentiated on the basis of the morphometrics of the hard parts of the haptor and male copulatory organ. The eight species represent the first records of species directly attributed to Ligophorus from the Red Sea. Measurements of the haptoral hard-parts and the male copulatory organ of the new species are analysed with the aid of Principal Component Analysis. Three morphological types of male copulatory organ, five types of anchor, and two types of ventral and three types of dorsal bars were distinguished among these species. L. bykhowskyi and L. zhangi from C. crenilabris have the same type of male copulatory organ and anchors. Those species from Liza carinata have only one common morphological character, a thick copulatory tube, but have two types of accessory piece, four types of anchors and three types of bars. All species of Ligophorus found on mullets in the Red Sea have an accessory piece without a distal bifurcation and thus differ from most species of this genus from other regions of the world’s oceans.     

Five new species of <Emphasis Type="Italic">Conocybe</Emphasis> (Agaricomycetes,Bolbitiaceae) from Russia

Five new Conocybe species are described from Russia based on collections made in different parts of the country. One species (C. olivaceopileata) belongs to sect. Conocybe, two species (C. praticola and C. coniferarum) to sect. Mixtae. The ornamented basidiospores of C. confundens and C. incerta is characteristic for sect. Ochromarasmius. All new species are described based on morphology and, in some cases, on DNA sequencing (ITS rDNA). Photos of basidiocarps, illustrations of microstructures and a comparison with similar taxa are given.     

Multilocus phylogeny of <Emphasis Type="Italic">Clonostachys</Emphasis> subgenus <Emphasis Type="Italic">Bionectria</Emphasis> from Brazil and description of <Emphasis Type="Italic">Clonostachys chloroleuca</Emphasis> sp. nov.

Phylogenetic analyses based on protein-encoding gene exons and introns of ATP citrate lyase (ACL1), beta tubulin (TUB), the largest subunit of RNA polymerase II (RPB1), and translation elongation factor 1-α (TEF1) are used for inferring the existence of a new Clonostachys species from the Cerrado biome in Brazil, described here as C. chloroleuca. The species produces dimorphic, primary, and secondary conidiophores that form consistently greenish conidial masses on artificial media. It resembles therefore C. rosea f. catenulata although it differs from this species by less adpressed branches in the secondary conidiophores. The new species is also phylogenetically related to C. byssicola and C. rhizophaga. Our inventory suggests that C. byssicola, C. chloroleuca, C. pseudochroleuca, C. rhizophaga, C. rogersoniana, and C. rosea commonly occur in native and agriculturally used soils of the Cerrado and Amazon Forest. Using sequences available from two genome-sequenced strains employed as biological control agents, we confirm the identity of the European strain IK726 as C. rosea and identify strain 67-1 from China as C. chloroleuca.     

<Emphasis Type="Italic">Viola woosanensis</Emphasis>, a recurrent spontaneous hybrid between <Emphasis Type="Italic">V. ulleungdoensis</Emphasis> and <Emphasis Type="Italic">V. chaerophylloides</Emphasis> (Violaceae) endemic to Ulleung Island,Korea

Ulleung Island is an oceanic volcanic island in Korea, which has never been connected to the adjacent continent. Previous studies highlighted Ulleung Island as an excellent system to study the pattern and process of early stages of flowering plant evolutions on oceanic island. The predominant mode of speciation in flowering plants on Ulleung Island appears to be anagenesis. However, the potentially important role of hybrid speciation among incompletely reproductively isolated lineages cannot be ruled out. Viola woosanensis (Violaceae) is of purportedly hybrid origin between V. ulleungdoensis (i.e., formerly recognized as V. selkirkii in Ulleung Island) and V. chaerophylloides, based on morphology. To examine the origin of V. woosanensis, we sampled a total of 80 accessions, including V. woosanensis and its putative parental species and sequenced nrDNA ITS, and four highly variable chloroplast noncoding regions (trnL-trnF, rpl16 intron, atpF-atpH, and psbA-trnH). Representative species of Viola from Korea were also included in the phylogenetic analyses (maximum parsimony, maximum likelihood, and Bayesian inference). Additive polymorphic sites in the nrDNA ITS regions were confirmed by cloning amplicons from representative species. The molecular data strongly supported the hybrid origin of V. woosanensis, and the maternal and paternal parent were determined to be V. ulleungdoensis and V. chaerophylloides, respectively. The presence of two parental ribotypes in V. woosanensis (with the exception in one population) was confirmed by cloning, suggesting V. woosanensis is primarily the F₁ generation. No trace of backcrossing and introgression with its parents was detected due to low fertility of hybrid species. We found a multiple and unidirectional hybrid origin of V. woosanensis. Additional studies are required to determine which factors contribute to asymmetric gene flow of Viola species in Ulleung Island.     

Two new species of <Emphasis Type="Italic">Conidiobolus</Emphasis> occurring in Anhui,China

Two new species of Conidiobolus were isolated from Anhui Province, China. A polyphasic taxonomic approach comprising morphological characteristics and molecular data (the nuclear large subunit of ribosomal DNA and the translation elongation factor 1 alpha gene sequences) was applied to determine their novel taxonomic status in the genus Conidiobolus. The new species C. mirabilis is a sister group to C. thromoides, but morphologically differs by smaller primary conidia and a unique formation of zygospores among two to four adjacent hyphal segments. The other new species C. pachyzygosporus characterized with thick-walled zygospores is phylogenetically closely related to C. antarcticus, C. couchii, and C. osmodes.     

<Emphasis Type="Italic">Cacopsylla biwa</Emphasis> sp. nov. (Hemiptera: Psyllidae): a new pest of loquat <Emphasis Type="Italic">Eriobotrya japonica</Emphasis> (Rosaceae) in Japan

A new psyllid species, Cacopsylla biwa Inoue, sp. nov., is described from Tokushima Prefecture, Shikoku, Japan. This new species develops only on Eriobotrya japonica (Thunb.) Lindl. (Rosaceae), causing severe damage to its fruits and flowers. It is strongly suspected that C. biwa is an alien species. Morphological similarities and host-plant relationships indicate that C. biwa is most closely related to Cacopsylla eriobotryae (Yang) comb. nov. (transferred from Edentatipsylla Li), which occurs in Taiwan and feeds on Eriobotrya deflexa (Hemsl.) Nakai. Morphological diagnostic characteristics of C. biwa and differences from the other congeners are discussed. Information is provided on the biology and life cycle of the new species.     

A new species and a new combination in <Emphasis Type="Italic">Ctenitis</Emphasis> (Dryopteridaceae) from South America

We describe a new species and propose a new combination of Ctenitis from South America. The new species is from Peru. We named it Ctenitis megalastriformis due to the resemblance to Megalastrum. The new combination corresponds to the species known until now as C. pedicellata. This species should be called C. nervata, based on the older name Aspidium nervatum. Lectotypes are designated for A. pedicellatum and Dryopteris indecora, both considered here to be synonyms of C. nervata.     

The male abdominal,genital and pregenital sclerites and musculature in <Emphasis Type="Italic">Neria commutata</Emphasis> (Czerny, 1930) (Diptera,Micropezidae)

The muscles of the male abdomen and genitalia of Micropezidae were studied for the first time by the example of Neria commutata (Czerny, 1930). Based on analysis of the sclerites and musculature of the male genitalia of Micropezidae as compared to those of the previously studied Acalyptratae and Aschiza, we revealed several apomorphies of this group. The hypandrial complex is characterized by the presence of the phallic retractors and protractors M1 and M2, and the epandrial complex, by the presence of muscles M3 of the subepandrial sclerite, muscles M4 of the surstyli, muscles M7 of the cerci, and also the tergosternal muscles M5; all these muscles correspond to the ground plan of Cyclorrhapha. The following characters are considered apomorphic: the splitting of intersegmental sternal muscles ISM5–6 into 4 pairs that ensure the functioning of the forcipate appendages of sternite V; development of syntergosternite VII and reduction of muscles ISM6–7; the splitting of muscles M3 of the subepandrial sclerite into 4 pairs, enhancing the function of this sclerite; the appearance of pregonites with the associated muscles M42, which probably occurred independently several times in the evolution of different groups of Cyclorrhapha; asymmetry of syntergosternites VII and VIII and their muscles. The sclerites and muscles of the epandrium and hypandrium are characterized by complete symmetry.     

Revision of the shield-bug genera <Emphasis Type="Italic">Holcostethus</Emphasis> Fieber and <Emphasis Type="Italic">Peribalus</Emphasis> Mulsant et Rey (Heteroptera,Pentatomidae) of the Palaearctic Region

A complex of the heteropteran genera centering around Peribalus Mulsant et Rey and Holcostethus Fieber is considered. The genus Dryadocoris Kirkaldy reveals no relationship with the above genera and is believed to represent a separate clade of the family Pentatomidae. The genera Peribalus and Holcostethus are revised. The former includes three subgenera: Peribalus s. str. with two species, Asioperibalus subgen. n. (type species Cimex inclusus Dohrn) with six species, and Tianocoris subgen. n. (type species Holcostethus manifestus Kiritshenko) with two species. Holcostethus embraces two subgenera: Holcostethus s. str. and the monotypic Enigmocoris subgen. n. (type species H. fissiceps Horváth). Two new species are described: Peribalus tianshanicus sp. n. from the Tien Shan Mts. and P. przewalskii sp. n. from the northern part of China (Huan He River). P. capitatus Jakovlev and P. vernalis (Wolff) are downgraded to subspecies of P. strictus (F.). P. ovatus Jakovlev is synonymized with P. inclusus (Dohrn). Two new monotypic genera related to the revised complex of genera are established, Paraholcostethus gen. n. (type species Peribalus breviceps Horváth) and Himalayastethus gen. n. (type species H. pilosus sp. n. from Kashmir). A key to, and morphometric characters for all the taxa considered are provided. The key characters, including both male and female genitalia, are illustrated, and distributional maps are given.     

Taxonomy and phylogeny of <Emphasis Type="Italic">Cryptocoryneum</Emphasis> (Pleosporales,Dothideomycetes)

Species of Cryptocoryneum were taxonomically reassessed on the basis of morphological observations and the results of molecular phylogenetic analysis. Eighteen isolates of Cryptocoryneum species, namely two strains from Africa, three from Europe, and 13 from Japan, were phylogenetically analysed using sequences of nuclear rDNA internal transcribed spacers (ITS) and the partial sequence of the translation elongation factor 1α gene (TEF1). The phylogenetic analysis indicated that Cryptocoryneum species formed a monophyletic clade and were closely related to Lophiotrema (Lophiotremataceae) and Aquasubmersa (incertae sedis) in the Pleosporales (Dothideomycetes). We examined holotype specimens of C. fasciculatum, C. hysterioides, and Torula uniformis and concluded that these species are conspecific, with C. hysterioides having priority. Although C. hysterioides has long been regarded as a synonym of C. condensatum, we consider C. hysterioides to be a distinct species within the genus. We found several cryptic species that were morphologically similar to C. condensatum sensu lato, but that could be separated on the basis of conidial size and the number of conidial arms and conidial septa, characters that seem to be informative for species delimitation within Cryptocoryneum. A total of seven new species, namely C. akitaense, C. brevicondensatum, C. congregatum, C. japonicum, C. longicondensatum, C. paracondensatum, and C. pseudorilstonei, are described and illustrated. A key to species accepted in Cryptocoryneum is provided.     

Usefulness of the Non-conventional <Emphasis Type="Italic">Caenorhabditis elegans</Emphasis> Model to Assess <Emphasis Type="Italic">Candida</Emphasis> Virulence

Invasive candidiasis is caused mainly by Candida albicans, but other Candida species have increasing etiologies. These species show different virulence and susceptibility levels to antifungal drugs. The aims of this study were to evaluate the usefulness of the non-conventional model Caenorhabditis elegans to assess the in vivo virulence of seven different Candida species and to compare the virulence in vivo with the in vitro production of proteinases and phospholipases, hemolytic activity and biofilm development capacity. One culture collection strain of each of seven Candida species (C. albicans, Candida dubliniensis, Candida glabrata, Candida krusei, Candida metapsilosis, Candida orthopsilosis and Candida parapsilosis) was studied. A double mutant C. elegans AU37 strain (glp-4;sek-1) was infected with Candida by ingestion, and the analysis of nematode survival was performed in liquid medium every 24 h until 120 h. Candida establishes a persistent lethal infection in the C. elegans intestinal tract. C. albicans and C. krusei were the most pathogenic species, whereas C. dubliniensis infection showed the lowest mortality. C. albicans was the only species with phospholipase activity, was the greatest producer of aspartyl proteinase and had a higher hemolytic activity. C. albicans and C. krusei caused higher mortality than the rest of the Candida species studied in the C. elegans model of candidiasis.     

A review of the fauna of the subgenus <Emphasis Type="Italic">Troginus</Emphasis>, genus <Emphasis Type="Italic">Carpelimus</Emphasis> (Coleoptera,Staphylinidae), from tropical Africa

The review includes seven species, three new species are described: Carpelimus maliensis, C. neuterus, and C. xenosus spp. n. The names Trogophloeus variegatus Cameron, 1944, T. ruandanus Cameron, 1956, and Carpelimus maroccanus Gildenkov, 2004 are synonymized with Carpelimus atomus (Saulcy, 1864). Carpelimus rondaensis is downgraded to the subspecies C. boops rondaensis (Fagel, 1957). Lectotype of Trogophloeus dundoensis Cameron, 1950 is designated. New data on the morphology and distribution of Carpelimus (Troginus) species are given.     

New Species of <Emphasis Type="Italic">Crassatina</Emphasis> (Bivalvia) from the Middle and Upper Eocene of Ukraine

Representatives of the genus Crassatina from the Upper Eocene Mandrikovka Beds in the vicinity of Dnepr (former Dnepropetrovsk) are discussed and figured. From the Mandrikovka assemblage, two new species, C. conquisita and C. insolita, are described. One more new species, C. subcostata, is described from the Middle Eocene deposits of southern suburbs of Krivoi Rog. Two species, C. raricostata (Klushnikov) and C. expolita (Klushnikov), which were originally established as varieties, are redescribed and their species rank is substantiated.     

Fossil wood of <Emphasis Type="Italic">Betula erkovetskiensis</Emphasis> sp. nov. (Betulaceae) from the Miocene of the Erkovetskii Brown Coal Field,Amur Region,Russia

A new species, Betula erkovetskiensis Blokhina et O.V. Bondarenko (Betulaceae), from the deposits of the Sazanka Formation (upper Middle?Upper Miocene) of the Erkovetskii Brown Coal Field (Amur Region, Russia) is described based on anatomical features of fossil wood. The new species shows some wood anatomical characters of the extant birch subgenus Betula, B. davurica, B. nigra (section Dahuricae), and B. papyrifera (section Betula). Fossil wood of Betula is found in the Amur Region for the first time.     

<Emphasis Type="Italic">Talaromyces heiheensis</Emphasis> and <Emphasis Type="Italic">T. mangshanicus</Emphasis>, two new species from China

Two new species, Talaromyces heiheensis from rotten wood and T. mangshanicus isolated from soil, are illustrated and described as new to science in sections Trachyspermi and Talaromyces. The phylogenetic positions of the two new species inferred from the internal transcribed spacer, beta-tubulin, calmodulin and RNA polymerase II second largest subunit regions were carried out. Talaromyces heiheensis is phylogenetically closely related to T. albobiverticillius, T. rubrifaciens, T. solicola and T. erythromellis, and characterised by slow growth on Czapek yeast autolysate agar at 25 °C, orange conidia en masse on malt extract agar at 25 °C, biverticillate and terverticillate conidiophores, acerose phialides and subglobose to ellipsoidal, smooth-walled conidia. Talaromyces mangshanicus is related to T. kendrickii, T. qii and T. thailandensis, and characterised by slow-growing colonies with absent or sparse sporulation on CYA agar at 25 °C, conidia en masse greyish purple, purplish red soluble pigment on yeast extract agar (YES) at 25 °C, biverticillate conidiophores, ampulliform phialides and subglobose to ellipsoidal conidia with echinulate walls. They are distinguished from the known species in culture characteristics on four standard media, microscopic features and sequence data.     

<Emphasis Type="Italic">Cortinarius</Emphasis> sect. <Emphasis Type="Italic">Riederi</Emphasis>: taxonomy and phylogeny of the new section with European and North American distribution

Cortinarius is one of the most species-rich genera of mushroom-forming fungi. Based on phylogenetic and morphological evidence, Cortinarius, sect. Riederi, is introduced at sectional level (= subsect. Riederi sensu Brandrud & Melot). The taxonomy, phylogeny, ecology and distribution of not only mainly European but also including some North American taxa of this section are treated, which includes nine species and two varieties. Of these, three taxa are described as new (C. burlinghamiae, C. pallidoriederi and C. argenteolilacinus var. dovrensis). The sect. Riederi species possess morphological features similar to Phlegmacium group(s) and forms a phylogenetically isolated lineage, with no supported affinity to other phlegmacioid groups. Three taxa are known from both Europe and North America, two species are known only from North America and five only from Europe. Altogether, eight of the ten taxa are associated with conifers or northern (boreal-subalpine) deciduous trees (Betula spp.). Only two species occur in more temperate forests (Fagus forests), and no species have so far been found in thermophilous Quercus forests
