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.     

Taxonomic hierarchy of the phylum <Emphasis Type="Italic">Firmicutes</Emphasis> and novel <Emphasis Type="Italic">Firmicutes</Emphasis> species originated from various environments in Korea

This study assessed the taxonomic hierarchy of the phylum Firmicutes as well as elucidated the isolation and classification states of novel Firmicutes species isolated from Korean territory. The hierarchical classification system of the phylum Firmicutes has been developed since 1872 when the genus Bacillus was first reported and has been generally adopted since 2001. However, this taxonomic hierarchy is still being modified. Until Feb. 2017, the phylum Firmicutes consisted of seven classes (Bacilli, Clostridia, Erysipelotrichia, Limnochordia, Negativicutes, Thermolithobacteria, and Tissierellia), 13 orders, 45 families, and 421 genera. Firmicutes species isolated from various environments in Korea have been reported from 2000, and 187 species have been approved as of Feb. 2017. All Firmicutes species were affiliated with three classes (Bacilli, Clostridia, and Erysipelotrichia), four orders (Bacillales, Lactobacillales, Clostridiales, and Erysipelotrichales), 17 families, and 54 genera. A total of 173 species belong to the class Bacilli, of which 151 species were affiliated with the order Bacillales and the remaining 22 species with the order Lactobacillales. Twelve species belonging to the class Clostridia were affiliated within only one order, Clostridiales. The most abundant family was Bacillaceae (67 species), followed by the family Paenibacillaceae (56 species). Thirteen novel genera were created using isolates from the Korean environment. A number of Firmicutes species were isolated from natural environments in Korean territory. In addition, a considerable number of species were isolated from artificial resources such as fermented foods. Most Firmicutes species, belonging to the families Bacillaceae, Planococcaceae, and Staphylococcaceae, isolated from Korean fermented foods and solar salterns were halophilic or halotolerant. Firmicutes species were isolated from the whole territory of Korea, especially large numbers from Provinces Gyeonggi, Chungnam, and Daejeon.     

Revision of <Emphasis Type="Italic">Neolebouria</Emphasis> Gibson, 1976 (Digenea: Opecoelidae), with <Emphasis Type="Italic">Trilobovarium</Emphasis> n. g., for species infecting tropical and subtropical shallow-water fishes

A new opecoelid trematode is reported from fishes of the Lethrinidae, Lutjanidae and Nemipteridae off Lizard Island on the northern Great Barrier Reef, Australia. The new species keys to Neolebouria Gibson, 1976 and shows strong similarity to several species of that genus, but is not consistent with the type-species, N. georgiensis Gibson, 1976, or others known from temperate/polar and/or deep-sea fishes. The new species is also phylogenetically distant from N. lanceolata (Price, 1934) Reimer, 1987, the only representative of the genus for which molecular data are available. A new genus, Trilobovarium n. g., is proposed for the new species, T. parvvatis n. sp. Eight morphologically similar species, previously recognised as belonging to Neolebouria, from shallow-water, mostly tropical/subtropical fishes, are transferred to Trilobovarium: T. diacopae (Nagaty & Abdel Aal, 1962) n. comb.; T. ira (Yamaguti, 1940) n. comb.; T. khalili (Ramadan, 1983) n. comb.; T. krusadaiense (Gupta, 1956) n. comb.; T. lineatum (Aken’Ova & Cribb, 2001) n. comb.; T. moretonense (Aken’Ova & Cribb, 2001) n. comb.; T. palauense (Machida, 2014) n. comb.; and T. truncatum (Linton, 1940) n. comb. Paramanteriella Li, Qiu & Zhang, 1988 is resurrected for five species of Neolebouria with a post-bifurcal genital pore: P. cantherini Li, Qiu & Zhang, 1988; P. capoori (Jaiswal, Upadhyay, Malhotra, Dronen & Malhotra, 2014) n. comb.; P. confusa (Overstreet, 1969) n. comb.; P. leiperi (Gupta, 1956) n. comb.; and P. pallenisca (Shipley & Hornell, 1905) n. comb. Neolebouria georgenascimentoi Bray, 2002, a species with an exceptionally long cirrus-sac, is transferred to Bentholebouria Andres, Pulis & Overstreet, 2004 as B. georgenascimentoi (Bray, 2002) n. comb., and N. maorum (Allison, 1966) Gibson 1976, an unusual species known from cephalopods, is designated a species incertae sedis. Eleven species are retained in a revised concept of Neolebouria.     

New sterigmatocystin-producing species of <Emphasis Type="Italic">Aspergillus</Emphasis> section <Emphasis Type="Italic">Versicolores</Emphasis> from indoor air in Croatia

Multilocus DNA sequence-based identification methods raised the number of known species assigned to the Aspergillus section Versicolores. Currently, there are 16 species accepted in the section, including A. amoenus, A. austroafricanus, A. creber, A. cvjetkovicii, A. fructus, A. griseoaurantiacus, A. hongkongensis, A. jensenii, A. protuberus, A. puulaauensis, A. subversicolor, A. sydowii, A. tabacinus, A. tennesseensis, A. venenatus, and A. versicolor. Based on morphological identifications, most of these species were identified as either A. sydowii or A. versicolor, with the latter reported to have a world-wide distribution, growing in many habitats. Aspergillus versicolor has been implicated in health hazards including sick building syndrome, human and animal mycoses, and contamination of food and feed were assigned primarily to this species. A. versicolor is still commonly isolated from indoor surveys, even though species such as A. jensenii and A. creber seem more common. From indoor air samples collected at a grain mill in Croatia, we isolated an undescribed species assigned to the Aspergillus section Versicolores. A polyphasic approach, including sequence-based methods, morphological and physiological studies, was used for species characterization and in this paper is described as Aspergillus pepii. Additionally, sterigmatocystin producing abilities have been confirmed. Based on a combined phylogenetic tree, morphological features and sterigmatocystin producing abilities, A. pepii is closely related to A. versicolor. Further studies should explore the frequency of the species in indoor environments and its medical, industrial, and environmental significance.     

The structure of the claspettes in the male genitalia of the subgenus <Emphasis Type="Italic">Ochlerotatus</Emphasis> Lynch Arribalzaga of the genus <Emphasis Type="Italic">Aedes</Emphasis> Meigen (Diptera,Culicidae) and their diagnostic significance

The structure of the claspettes (modified projections in the male genitalia) in species of the subgenus Ochlerotatus Lynch Arribalzaga of the genus Aedes Meigen is described in detail. A thorough investigation of the three-dimensional structure of the claspettes is necessary for identification of the Ochlerotatus species from Russia. The study of 30 species of Ochlerotatus demonstrated that frequently the use of the claspette structure as a diagnostic character was incorrect when the claspettes were described as flat structures. Examination of the three-dimensional structure of the claspettes has revealed characters differentiating Aedes diantaeus, A. intrudens and A. pullatus; A. communis, A. punctor, and A. hexodontus; A. annulipes, A. excrucians, and A. euedes, as well as some other species.     

<Emphasis Type="Italic">Phialemoniopsis endophytica</Emphasis> sp. nov., a new species of endophytic fungi from <Emphasis Type="Italic">Luffa cylindrica</Emphasis> in Henan,China

During a survey of endophytic fungi in the cucurbit plants collected from Henan, China, a new species, Phialemoniopsis endophytica was isolated from the lower stem of Luffa cylindrica. It differs from other Phialemoniopsis species by its cylindrical to flask-shaped phialides, falcate conidia with blunt ends, ostiolate pycnidium-like conidiomata without marginal setae and ellipsoidal chlamydospores. Multi-locus (ITS, LSU, ACT, and TUB) phylogenetic analysis confirmed that P. endophytica is distinct from other species. A synopsis of the morphological characters of the new species is provided.     

<Emphasis Type="Italic">Bruguiera hainesii</Emphasis>, a critically endangered mangrove species,is a hybrid between <Emphasis Type="Italic">B. cylindrica</Emphasis> and <Emphasis Type="Italic">B. gymnorhiza</Emphasis> (Rhizophoraceae)

Bruguiera hainesii (Rhizophoraceae) is one of the two Critically Endangered mangrove species listed in the IUCN Red List of Threatened Species. Although the species is vulnerable to extinction, its genetic diversity and the evolutionary relationships with other Bruguiera species are not well understood. Also, intermediate morphological characters imply that the species might be of hybrid origin. To clarify the genetic relationship between B. hainesii and other Bruguiera species, we conducted molecular analyses including all six Bruguiera species using DNA sequences of two nuclear genes (CesA and UNK) and three chloroplast regions (intergenic spacer regions of trnL-trnF, trnS-trnG and atpB-rbcL). For nuclear DNA markers, all nine B. hainesii samples from five populations were heterozygous at both loci, with one allele was shared with B. cylindrica, and the other with B. gymnorhiza. For chloroplast DNA markers, the two haplotypes found in B. hainesii were shared only by B. cylindrica. These results suggested that B. hainesii is a hybrid between B. cylindrica as the maternal parent and B. gymnorhiza as the paternal one. Furthermore, chloroplast DNA haplotypes found in B. hainesii suggest that hybridization has occurred independently in regions where the distribution ranges of the parental species meet. As the IUCN Red List of Threatened Species currently excludes hybrids (except for apomictic plant hybrids), the conservation status of B. hainesii should be reconsidered.     

New <Emphasis Type="Italic">Penicillium</Emphasis> and <Emphasis Type="Italic">Talaromyces</Emphasis> species from honey,pollen and nests of stingless bees

Penicillium and Talaromyces species have a worldwide distribution and are isolated from various materials and hosts, including insects and their substrates. The aim of this study was to characterize the Penicillium and Talaromyces species obtained during a survey of honey, pollen and the inside of nests of Melipona scutellaris. A total of 100 isolates were obtained during the survey and 82% of those strains belonged to Penicillium and 18% to Talaromyces. Identification of these isolates was performed based on phenotypic characters and β-tubulin and ITS sequencing. Twenty-one species were identified in Penicillium and six in Talaromyces, including seven new species. These new species were studied in detail using a polyphasic approach combining phenotypic, molecular and extrolite data. The four new Penicillium species belong to sections Sclerotiora (Penicillium fernandesiae sp. nov., Penicillium mellis sp. nov., Penicillium meliponae sp. nov.) and Gracilenta (Penicillium apimei sp. nov.) and the three new Talaromyces species to sections Helici (Talaromyces pigmentosus sp. nov.), Talaromyces (Talaromyces mycothecae sp. nov.) and Trachyspermi (Talaromyces brasiliensis sp. nov.). The invalidly described species Penicillium echinulonalgiovense sp. nov. was also isolated during the survey and this species is validated here.     

Two novel <Emphasis Type="Italic">Aspergillus</Emphasis> species from hypersaline soils of The National Park of Lake Urmia,Iran

Two novel Aspergillus species, one belonging to the section Terrei and the other to section Flavipedes, were isolated from hypersaline soils of The National Park of Lake Urmia (Iran) and are here described as Aspergillus iranicus and Aspergillus urmiensis. A polyphasic taxonomic approach comprising extrolite profiles, phenotypic characters and molecular data (beta-tubulin, calmodulin and ribosomal polymerase II second largest subunit gene sequences) was applied to determine their novel taxonomic status. Aspergillus iranicus (CBS 139561^T) is phylogenetically related to A. carneus, A. niveus, A. allahabadii and A. neoindicus, and it can be differentiated from those species by a unique extrolite pattern (citrinin, gregatins, and a terrequinone) and its conidial colour. Aspergillus urmiensis (CBS 139558^T) shares a most recent common ancestor with A. templicola. The former species produces globose vesicles, and those of A. templicola are predominantly elongate. The Aspergillus urmiensis isolates produce several uncharacterized extrolites. Two other strains obtained during this study reside in a clade, together with the type strain of A. movilensis (CCF 4410^T), and are identified accordingly. Based on the phylogenetic data presented in this study, A. frequens is reduced to synonymy with A. micronesiensis and A. mangaliensis is considered to be a synonym of A. templicola.     

A new species of the jewel-beetle subgenus <Emphasis Type="Italic">Acmaeodera</Emphasis> (<Emphasis Type="Italic">Ptychomus</Emphasis>) Marseul, 1866 from Oman (Coleoptera,Buprestidae: Polycestinae: Acmaeoderini)

A new species of buprestid beetles, Acmaeodera (Ptychomus) koshtali sp. n. (Coleoptera: Buprestidae: Polycestinae) from Oman is described, illustrated, and compared with the closely related species A. (P.) arabica Gory, 1840 and A. (P.) sancta Théry, 1926 which are also recorded from the Arabian Peninsula.     

First Record of the Subgenus <Emphasis Type="Italic">Empis</Emphasis> (<Emphasis Type="Italic">Planempis</Emphasis>) (Diptera,Empididae) from Middle Asia,with Description of a New Species

A new species of the subgenus Planempis Frey, 1953 (Diptera: Empididae), Empis (Planempis) gussakovskiisp. n., is described from Tajikistan, being the first record of the subgenus from Middle Asia. The relationships of the new species within the subgenus Planempis are shortly discussed. An updated check-list of Planempis species is provided.     

Updates on East Asian <Emphasis Type="Italic">Asterostroma</Emphasis> (Russulales,Basidiomycota): new species and new records from Thailand and China

Two new species from northern Thailand, Asterostroma bambusicola and A. vararioides, are described and illustrated. Asterostroma bambusicola is characterized by globose, echinulate, and amyloid basidiospores and growing on rotten bamboo. Asterostroma vararioides is distinguished by the presence of Vararia-like dichohyphae, subglobose, smooth, and amyloid basidiospores and growing on bark of living angiosperm trees. In the phylogenetic tree inferred from a combined dataset of ITS and nLSU sequence data of Peniophoraceae, A. bambusicola forms a distinct lineage in the sect. Asterostroma clade, whereas A. vararioides and A. laxum form the sect. Laevispora clade. Asterostroma andinum, reported from China for the first time, forms a distinct lineage sister to Gloiothele spp. and Scytinostroma portentosum group. Asterostroma muscicola is reported from Thailand and China for the first time. A key to the species of Asterostroma from Thailand and China is provided.     

Free-living nematodes of the genus <Emphasis Type="Italic">Alaimella</Emphasis> Cobb 1920 (Nematoda: Leptolaimidae): A description of <Emphasis Type="Italic">A. macramphis</Emphasis> sp. n. from the White Sea and a revision of the genus

Alaimella cincta Cobb 1920 and Alaimella macramphis sp. n. are described and illustrated. Both the species were first recorded for the White Sea in northern Russia. A. cincta occurs in the shells of the agglutinated foraminiferan Reophax curtus, as well as freely in bottom sediments. A. macramphis sp. n. is described from a single male sampled from bottom sediments. A. macramphis sp. n. is distinguished from two previously known species of Alaimella (A. cincta Cobb 1920 and A. truncate Cobb 1920) by having a longer body, longer cephalic setae, and a wide amphid equal to the respective body diameter. The new species also differs from A. truncate by the distinct striation of the cuticular annulations. The Alaimella species are additionally characterized by having a posterior glandular widening of the esophagus. An emended diagnosis of the genus Alaimella Cobb 1920 and a key for species identification are provided.     

<Emphasis Type="Italic">Athyrium sessilipinnum</Emphasis>: A new lady fern (Athyriaceae) from southern China

A new species of Athyrium from southern China is described and illustrated as Athyrium sessilipinnum. Morphological comparisons among this new species and similar ones (e.g., A. arisanense, A. gedeanum, A. epirachis, and A. otophorum) are provided. Molecular evidence reveals a sister relationship between the new species and A. arisanense. The most distinctive characters of A. sessilipinnum are the sessile, non-pinnatifid and non-shortened pinnae.     

A new subgenus and a new species of the tenebrionid genus <Emphasis Type="Italic">Leptodes</Emphasis> Dejean, 1834 (Coleoptera,Tenebrionidae)

The genus Leptodes was erected by Dejean (1834) for a single species, Sepidium boisduvalii Zubkoff, 1833, which is, consequently, the type species by monotypy. Kaszab (1959) established in Leptodes the subgenus Leptodinopsis based on the same type species, Sepidium boisduvalii. Thus the names Leptodes and Leptodinopsis are objective synonyms: Leptodes Dejean, 1834 = Leptodinopsis Kaszab, 1959, syn. n. A new subgenus Mesoleptodes G. Medvedev et Iljina subgen, n. (type species Leptodes semenowi Reitter, 1892) is established for species which Kaszab included in Leptodes s. str. A new species, Leptodes daghestanicus G. Medvedev et Iljina, sp. n., is described from Daghestan.     

Molecular phylogeny of pectinase genes <Emphasis Type="Italic">PGU</Emphasis> in the yeast genus <Emphasis Type="Italic">Saccharomyces</Emphasis>

Using yeast genome databases and literature data, phylogenetic analysis of pectinase PGU genes from 112 Saccharomyces strains assigned to the biological species S. arboricola, S. bayanus (var. uvarum), S. cariocanus, S. cerevisiae, S. kudriavzevii, S. mikatae, S. paradoxus, and the hybrid taxon S. pastorianus (syn. S. carlsbergensis) was carried out. A superfamily of divergent PGU genes was found. Natural interspecies transfer of the PGU gene both from S. cerevisiae to S. bayanus and from S. paradoxus to S. cerevisiae may, however, occur. Within the Saccharomyces species, identity of the PGU nucleotide sequences was 98.8–100% for S. cerevisiae, 86.1–95.7% for S. bayanus (var. uvarum), 94–98.3% for S. kudriavzevii, and 96.8–100% for S. paradoxus/S. cariocanus. For the first time, a family of polymeric PGU1b, PGU2b, PGU3b and PGU4b genes is documented for the yeast S. bayanus var. uvarum, a variety important for winemaking.     

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.
