Revision of the genus <Emphasis Type="Italic">Entactinosphaera</Emphasis> Foreman, 1963 and the new genus <Emphasis Type="Italic">Retientactinosphaera</Emphasis> gen. nov. (Paleozoic radiolaria)

The genus Entactinosphaera Foreman, 1963 is revised; it is shown to combine seven different genera, which are distinguished by morphological characters and belong to three orders of two radiolarian classes: the class Sphaerellaria, order Entactiniata (Bientactinosphaera, Entactinosphaera, Helioentactinia, Radiobisphaera), and class Spumellaria, orders Cancelliata (Retientactinosphaera, Magnisphaera) and Spongiata (Spongentactinia). New radiolarian taxa from the Middle Frasnian-Lower Famennian of the Timan-Pechora Basin and from the Lower Famennian of the Polar Ural Mountains, Russia, are described: Retientactinosphaera gen. nov., R. magnifica sp. nov., and R. clavata sp. nov.     

Three new species of <Emphasis Type="Italic">Stigmidium</Emphasis> and <Emphasis Type="Italic">Sphaerellothecium</Emphasis> (lichenicolous ascomycetes) on <Emphasis Type="Italic">Stereocaulon</Emphasis>

Sphaerellothecium stereocaulorum sp. nov., Stigmidium beringicum sp. nov., Stigmidium stereocaulorum sp. nov. and goniocysts are described on Stereocaulon species from the northern Holarctic. Endococcus nanellus is reported new to Alaska and Mongolia. Taxonomical novelties Sphaerellothecium stereocaulorum Zhurb. & Triebel, Stigmidium beringicum Zhurb. & Triebel, Stigmidium stereocaulorum Zhurb. & Triebel.     

Myrothecium-like (Ascomycota,Hypocreales) species from tropical areas: <Emphasis Type="Italic">Digitiseta</Emphasis> gen. nov. and additions to <Emphasis Type="Italic">Inaequalispora</Emphasis> and <Emphasis Type="Italic">Parvothecium</Emphasis>

Inaequalispora and Parvothecium are two myrothecium-like, closely related genera of Hypocreales. They are also morphologically similar, sharing sporodochial conidiomata, penicillate conidiophores, fusiform to ellipsoidal conidia accumulating in a green slimy drop, and hypha-like setoid extensions emerging through the conidial mass. During a revision of myrothecium-like isolates originating from rainforest areas of South America (Ecuador, Brazil) and Southeast Asia (Singapore), multilocus phylogenetic inferences (based on DNA sequence data of ITS, partial nuc 28S, and partial tef1a, rpb2 and tub2) and morphological studies concordantly revealed the occurrence of two undescribed species of Inaequalispora (I. longiseta sp. nov. and I. cylindrospora sp. nov.) and one undescribed species of Parvothecium (P. amazonensesp. nov.). Myrothecium setiramosum, M. dimorphum, and two undescribed taxa form the base of a new lineage, sister to the current Parvothecium lineage. This lineage is recognized as Digitiseta gen. nov., typified by D. setiramosa comb. nov. Digitiseta dimorpha comb. nov. is also proposed, and the new species D. parvodigitata sp. nov. and D. multidigitata sp. nov. are described.     

<Emphasis Type="Italic">Paraliparis adustus</Emphasis> and <Emphasis Type="Italic">Paraliparis bullacephalus</Emphasis>: two new snailfish species (Teleostei: Liparidae) from Alaska

Paraliparis adustus sp. nov., a snailfish species from the Bering Sea near the Aleutian Island Archipelago, Alaska, is described based on a single mesopelagic specimen. This new species is clearly distinguished by a combination of several morphological features and meristic counts, including long pointed gill rakers with 0–3 spinules at or near the tip, anus positioned forward near the pectoral symphysis, and color uniform brown. Paraliparis bullacephalus sp. nov. from Shelikof Strait, Gulf of Alaska, is also described. This new species is very similar in meristic characters and general body shape and size to P. holomelas Gilbert, but differs primarily in morphological features of the head, particularly in the shape of the dorsal contour of the head, snout, and opercular flap, mouth size, and eye position.     

A new species of <Emphasis Type="Italic">Brasiliomyces</Emphasis> (Erysiphaceae) on <Emphasis Type="Italic">Dalbergia cultrata</Emphasis> var. <Emphasis Type="Italic">cultrata</Emphasis> from Thailand

A powdery mildew fungus on leaves of Dalbergia cultrata var. cultrata (Fabaceae) collected at the Queen Sirikit Botanical Garden in northern Thailand is proven to be a new species of the genus Brasiliomyces and is described as B. chiangmaiensis sp. nov. with light and SEM micrographs. Differences in known Brasiliomyces species are discussed, and a key to species of this genus is provided.     

New species of <Emphasis Type="Italic">Clohiesia</Emphasis> and <Emphasis Type="Italic">Paraniesslia</Emphasis> collected from freshwater habitats in China

Two fungi collected from submerged woody debris were found to represent hitherto undescribed species of the ascomycete genera Clohiesia and Paraniesslia. They are described as Clohiesia curvispora sp. nov. and Paraniesslia aquatica sp. nov. based on morphological characters. Clohiesia curvispora is characterized by immersed ascomata under a clypeus, and unitunicate, cylindrical asci containing one-celled, curved, elongate-fusiform ascospores. Paraniesslia aquatica is characterized by small, superficial, setose ascomata, and unitunicate, clavate asci containing verrucose, brown ascospores. Each species is illustrated with light micrographs and compared with similar taxa in this article.     

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.     

<Emphasis Type="Italic">Metarhizium taii var. chongqingensis</Emphasis> Nov., Anamorph of <Emphasis Type="Italic">Cordyceps</Emphasis><Emphasis Type="Italic">chongqingensis</Emphasis> sp. Nov. Isolated from a Low Altitude Area in Chongqing,China

Previously, a new Cordyceps species was isolated from a low altitude area in Chongqing, China, and named Cordyceps chongqingensis sp. nov. In this study, its anamorph was isolated and designated CQM1^T. It grew optimally on Czapek medium supplied with 0.5% silkworm flour and 0.5% soybean oil meal at 25°C, pH 5.0–5.5. The phenotypic and molecular characteristics were investigated for its identification and typing. Morphological observations under a microscope revealed that this anamorph of Cordyceps chongqingensis sp. nov. was a new species of Metarhizium. Moreover, it was identified as one of the variants of Metarhizium taii based on sequences of 26S rDNA D1/D2 and ITS regions, and thus named Metarhizium taii var. chongqingensis nov.     

<Emphasis Type="Italic">Tubulideres seminoli</Emphasis> gen. et sp. nov. and <Emphasis Type="Italic">Zelinkaderes brightae</Emphasis> sp. nov. (Kinorhyncha,Cyclorhagida) from Florida

One new kinorhynch genus and species and one new species from the genus Zelinkaderes are described from sandy sediment off Fort Pierce, Florida. The new genus and species, Tubulideres seminoli gen. et sp. nov. is characterized by the presence of the first trunk segment consisting of a closed ring, the second segment of a bent tergal plate with a midventral articulation and the following nine segments consisting of a tergal and two sternal plates. Cuspidate spines are not present, but flexible tubules are located on several segments, and in particular concentrated on the ventral side of the second segment. Middorsal spines are present on all trunk segments and are alternatingly offset to a position slightly lateral to the middorsal line. Zelinkaderes brightae nov. sp. is characterized by its spine formula in having middorsal spines on trunk segments 4, 6 and 8–11, lateroventral acicular spines on segment 2, lateral accessory cuspidate spines on segments 2 and 8, ventrolateral cuspidate spines on segments 4–6 and 9, lateroventral acicular spines present on segments 8 and 9, and midterminal, lateral terminal and lateral terminal accessory spines on segment 11. The spine formula of Z. brightae nov. sp. places it in a position in between Z. submersus and a clade consisting of Z. klepali and Z. floridensis. The new findings on Z. brightae nov. sp. have led us to propose an emended diagnosis for the genus.     

Two new records of <Emphasis Type="Italic">Mycena</Emphasis> sect. <Emphasis Type="Italic">Sacchariferae</Emphasis> from Japan and type study of <Emphasis Type="Italic">Mycena cryptomeriicola</Emphasis> (sect. <Emphasis Type="Italic">Sacchariferae</Emphasis>)

Mycena cupulicola sp. nov. and M. adscendens var. carpophila, new to Japan, are described and illustrated. The former is characterized by having lageniform caulocystidia with a slightly thick-walled broadened base and no cheilocystidia. The latter is characterized by having a white pileus up to 1mm in diameter and narrowly conical caulocystidia. Mycena cryptomeriicola was confirmed to have inamyloid basoidiospores.     

Phylogenetic evaluation of anamorphic species of <Emphasis Type="Italic">Cirrenalia</Emphasis> and <Emphasis Type="Italic">Cumulospora</Emphasis> with the description of eight new genera and four new species

Four new helicoid anamorphic fungi collected from marine habitats in Egypt and Japan are described. Three marine and one terrestrial Cirrenalia species along with two Cumulospora species and the four new fungi were sequenced for LSU and SSU rDNA. Phylogenetic analyses of the generated sequences, along with those from GenBank, confirmed the polyphyly of the genera Cirrenalia and Cumulospora, and new genera are erected to accommodate the displaced species. Eight new genera, four new species and six new combinations are made: 1. Halazoon anam.-gen. nov. (Halazoon melhae sp. nov., H. fuscus for Cirrenalia fusca), 2. Moheitospora anam.-gen. nov. (Moheitospora fruticosae sp. nov., M. adarca for Cirrenalia adarca), 3. Moleospora anam.-gen nov. (Moleospora maritima sp. nov.), and 4. Glomerulispora anam.-gen. nov. (Glomerulispora mangrovis sp. nov); Cirrenalia pygmea, Cirrenalia tropicale and Cumulospora varius are transferred to the new genera, 5. Hydea anam.-gen. nov, 6. Matsusporium anam.-gen. nov., and 7. Moromyces anam.-gen. nov., respectively. These genera can be assigned to the order Lulworthiales, TBM (Torpedospora/Bertia/Melanospora) clade, while Cirrenalia macrocephala is nested within the order Halosphaeriales. Few morphological characters delineate the genera and species assigned to the Lulworthiales and this aspect is discussed in relation to the molecular data. The phylogenetic position of the terrestrial species, Cirrenalia japonica, shows that it is a member of the order Pleosporales, and a new genus, 8. Hiogispora anam.-gen. nov. is proposed for the fungus.     

<Emphasis Type="Italic">Kryptoglanis shajii</Emphasis>, an enigmatic subterranean-spring catfish (Siluriformes, <Emphasis Type="Italic">Incertae sedis</Emphasis>) from Kerala,India

This is the report of a new species of catfish, Kryptoglanis shajii nov. gen. and nov. sp., distinguished from all other genera of siluriform fishes by the combination of the following morphological characters: viz. the absence of dorsal fin; the presence of four pairs of barbels; an upwardly directed mouth, with a distinctly projecting lower jaw; subcutaneous eyes; anal fin completely confluent with the caudal fin; anal and caudal fins together carry 70–74 fin rays; and no spines in any of the fins. Kryptoglanis, which has a maximum recorded size of 59.1 mm in standard length, was collected from a well fed by subterranean springs. The type locality is a well located at the extreme western part of Western Ghats, near Chalakudy in Thrissur district, Kerala State, India.     

Hover-flies of the genus <Emphasis Type="Italic">Melanostoma</Emphasis> closely related to <Emphasis Type="Italic">Melanostoma dubium</Emphasis> (Diptera,Syrphidae)

Two new species of the genus Melanostoma Schin., 1860, closely related to M. dubium (Zetterstedt, 1838), are described, and a key to the species of this group is given. Melanostoma clausseni sp. n. and M. tschernovi sp. n. are closely related to M. dubium (Zett.), but differ in the uniformly black abdomen and legs. Melanostoma clausseni sp. n. differs from M. tschernovi sp. n. in the lustrous mesonotum and finely pruinose frons and face (in M. tschernovi, the face, frons, and mesonotum are covered with gray pruinosity). Holotypes of the new species are deposited in the collection of the Siberian Zoological Museum (Novosibirsk).     

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.     

<Emphasis Type="Italic">Fusarium matuoi</Emphasis> sp. nov. and its teleomorph <Emphasis Type="Italic">Cosmospora matuoi</Emphasis> sp. nov.

A group of Fusarium isolates from slime flux similar to F. aquaeductuum produced unique, strongly curved, aseptate, C-shaped conidia. They were found to be identical to F. splendens nom. nud. Dried specimens from which F. splendens was originally isolated were reexamined and characterized as a new species of Cosmospora. Cosmospora matuoi sp. nov. is proposed for the teleomorph, and Fusarium matuoi sp. nov. is proposed for its anamorph.     

New species of <Emphasis Type="Italic">Clitocybe </Emphasis>and <Emphasis Type="Italic">Crepidotus </Emphasis>(Agaricales) from eastern Honshu,Japan

 Three new species of Agaricales from eastern Honshu, Japan, are described and illustrated. (1) Clitocybe minutella sp. nov. (section Vernae), having white, very small, clitocyboid basidiomata with white, strigose mycelial tomentum at the base of the stipe and trichodermial elements in the pileipellis, occurs on leaf litter in deciduous oak forests. (2) Crepidotus longicomatus sp.nov. (section Echinospori), forms very small (up to 3.5 mm in diameter), reniform basidiomata densely covered overall with white to pale yellow, erect, thick-walled, long hairs. It has melleous, echinulate basidiospores, and was found on fallen dead branches in lowland oak forests. (3) Crepidotus virgineus sp. nov. (section Crepidotus), forming pure white, reniform basidiomata, has smooth, ellipsoid basidiospores, subfusiform-pedicellate to irregularly cylindrical cheilocystidia, and abundant clamp connections. It occurs on fallen dead branches in lowland oak forests.
