Contribution to the phylogeny and a new species of <Emphasis Type="Italic">Coccodiella</Emphasis> (Phyllachorales)

Coccodiella is a genus of plant-parasitic species in the family Phyllachoraceae (Phyllachorales, Ascomycota), i.e., tropical tar spot fungi. Members of the genus Coccodiella are tropical in distribution and are host-specific, growing on plant species belonging to nine host plant families. Most of the known species occur on various genera and species of the Melastomataceae in tropical America. In this study, we describe the new species C. calatheae from Panama, growing on Calathea crotalifera (Marantaceae). We obtained ITS, nrLSU, and nrSSU sequence data from this new species and from other freshly collected specimens of five species of Coccodiella on members of Melastomataceae from Ecuador and Panama. Phylogenetic analyses allowed us to confirm the placement of Coccodiella within Phyllachoraceae, as well as the monophyly of the genus. The phylogeny of representative species within the family Phyllachoraceae, including Coccodiella spp., graminicolous species of Phyllachora and taxa with erumpent to superficial stroma from several host families, suggests that the genus Phyllachora might be polyphyletic. Furthermore, tar spot fungi with superficial or erumpent perithecia seem to be restricted to the family Phyllachoraceae, independently of the host plant. We also discuss the biodiversity and host-plant patterns of species of Coccodiella worldwide.     

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.     

<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     

Mesozoic rissoid gastropods: History of the study,systematics, and diversity

The history of the study and review of generic and species diversity of Mesozoic rissoid gastropods are provided. The generic composition of Jurassic rissoid gastropods is revised, so that it is proposed to regard them as the family Rissoidae, comprising the genera Bralitzia, Buvignieria, Palaeoceratia, and Palaeorissoina. It is tentatively proposed to assign the genus Hudlestoniella to Rissoidae; this is caused by insufficient morphological knowledge of this genus. The family Palaeorissoidae is regarded as a synonym of Rissoidae. Stratigraphical and geographical distribution of Rissoidae genera is reviewed. From the Jurassic of European Russia, the following species of the genus Buvignieria are described: B. calloviana Gründel, B. imminuera Gründel, B. paucicostata Gründel, B. eichwaldiana (Rouillier), B. choroshovensis Gerasimov, and B. gruendeli sp. nov. The morphological characteristics and stratigraphical distribution of these species are provided. Based on extensive material, the taxonomic significance of particular conchological characters for the establishment of species is discussed.     

New Angarosphecidae (Insecta: Hymenoptera: Apoidea) from the Lower Cretaceous of Northeastern China

Two new species of the family Angarosphecidae, Angarosphex saxosus sp. nov. and Vitimosphex vividus sp. nov., from the Lower Cretaceous Yixian Formation of northeastern China are described and illustrated. Generic diagnoses are revised. The genera Palaeapis Hong, 1984, Mataeosphex: Zhang, 1985, and Calobaissodes Zhang, 1992 are synonymized under Angarosphex Rasnitsyn, 1975, and new combinations Angarosphex beiboziensis (Hong, 1984), comb. nov., Angarosphex venulosus (Zhang, 1985), comb. nov., and Angarosphex strigosus Zhang, 1992, comb. nov. are proposed. The genus Vitimosphex Rasnitsyn, 1975 is found reaching northeastern China in its distribution. New morphological data are presented to complete characteristics of the genera concerned.     

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.     

New data on trophic relations between eulophid parasitic wasps (Hymenoptera,Eulophidae) and lepidopterans in Ul’yanovsk Province

Twenty seven species of the family Eulophidae were reared from 20 new lepidopteran hosts in Ul’yanovsk Province. Among newly revealed host-parasitoid associations, 27, 9, 3, and 3 are those with Phyllonorycter (Gracillariidae), Stigmella and single species of Ectoedemia (Nepticulidae), Yponomeuta (Yponomeutidae), and Tischeria (Tischeriidae), respectively. Ectoparasitoids prevailed among parasitoids of the genus Phyllonorycter, and endoparasitoids, among parasitoids of the genera Stigmella and Tischeria.     

Polyphyletic origin in <Emphasis Type="Italic">Pimpinella</Emphasis> (Apiaceae): evidence in Western Europe

The genus Pimpinella L. comprises about 150 species, being one of the largest genera within the family Apiaceae (subfamily Apioideae). Previous molecular phylogenetic studies have shown that Pimpinella is a taxonomically complex group. In this study, evolutionary relationships among representatives from Western Europe have been inferred from phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer (ITS 1 and ITS 2) and plastid sequences (trnL intron and the trnL-F spacer), with a representative sampling included (168 accessions in the ITS analysis, representing 158 species; and 42 accessions in the cpDNA analysis representing 35 taxa of Pimpinella and closely related species). All analyses resolved that Pimpinella is a non-monophyletic group, and Pimpinella’s taxa that grow in Western Europe are part of phylogenetically independent groups that correspond to three different tribes of the subfamily Apioideae: Pimpinelleae (core group), Pyramidoptereae and Smyrnieae.     

An annotated list and molecular data on larvae of gryporhynchid tapeworms (Cestoda: Cyclophyllidea) from freshwater fishes in Africa

An annotated list of larvae (metacestodes) of gryporhynchid tapeworms (Cestoda: Cyclophyllidea) from freshwater fishes in Africa is provided with numerous new host and geographical records. Newly collected materials from Burundi, Democratic Republic of the Congo, Kenya, Madagascar, Namibia, Senegal, South Africa, Sudan and Zimbabwe practically double the total number of species reported from African fish so far. We confirm the occurrence of 16 species (five unidentified to the species level and most likely representing new taxa) belonging to the genera Amirthalingamia Bray, 1974 (1 species), Cyclustera Fuhrmann, 1901 (2 species), Dendrouterina Fuhrmann, 1912 (1 species), Neogryporhynchus Baer & Bona, 1960 (1 species), Paradilepis Hsü, 1935 (4 species), Parvitaenia Burt, 1940 (5 species), and Valipora Linton, 1927 (2 species). Additionally, metacestodes of four unidentified species of Paradilepis and Parvitaenia are reported from fish for the first time. Rostellar hooks of all species are illustrated and their measurements are provided together with a host-parasite list. The molecular phylogenetic analysis based on partial LSU rDNA sequences offers the first insight into the internal phylogenetic relationships within the family. Together with the morphological observations, the present study provides a taxonomic baseline for future studies on this largely neglected, but widely distributed and relatively frequent, group of parasites of African fishes, including economically important cichlids like tilapias and cyprinids.     

New cryptostomide bryozoans from the Upper Devonian of Transcaucasia and some aspects of the evolution of the order Cryptostomida

New bryozoans of the suborder Ptilodictyina of the order Cryptostomida are described from the Upper Famennian of Transcaucasia: those of the family Worthenoporidae, i.e., a genus Geranopora gen. nov. comprising three species G. fabulosa sp. nov. (type species), G. fida sp. nov., and G. finitima sp. nov., and those of a new family Mysticellidae fam. nov., i.e., a genus Mysticella gen. nov. comprising four species M. labyrinthica sp. nov. (type species), M. laudativa sp. nov., M. sacrosancta sp. nov., and M. ortiva sp. nov. Thus, a Late Devonian part of the evolutionary line of ptilodictyines is revealed that shows their radiation at the levels of families, genera, and species.     

Morphological similarity between echinoid taxa as a result of convergent and parallel evolution

Convergence is observed in groups, which are phylogenetically remote. A flat test is typical for some representatives of the order Cassiduloida, such as Jurassic and Early Cretaceous species of the genera Pygurus and Clypeus, and also many Cenozoic «sand dollars,» i.e., echinoids of the order Clypeasteroida. Both usually inhabit coarse sandy grounds of shallow areas. The superorder Spatangacea includes the so-called Echinocorys life form, which is characterized by an oval test with superficial nonpetaloid or subpetaloid ambulacra, marginal or inframarginal periproct, and absence of fascioles. These are the following genera: Early Cretaceous Corthya (family Collyritidae), Late CretaceousLate Paleocene Echinocorys (family Holas-teridae), Paleocene Isaster, Recent Isopatagus (family Isasteridae), Recent Scrippsechinus (family Palaeotro-pidae), and Recent Urechinus (family Urechinidae). In contrast to the majority of spatangaceans with the burrowing mode of life, these genera dwell on the substrate surface. In the Cenozoic, the monobasal apical system appears in some genera of the order Spatangoida, most genera of the order Cassiduloida, all groups of the orders Clypeasteroida and Oligopygoida, and in the genus Echinoneus (order Holectypoida). The paral-lelism is revealed in groups connected by remote relationships. At the end of the Middle Jurassic (Callovian) and, especially, Late Jurassic, the so-called disasterid echinoids (superorder Spatangacea) show a distinct trend to the loss of contact between ocular plates I and V and apices of the posterior ambulacra with the periproct, which are shifted to the anterior part of the apical system (genera Collyrites, Collyropsis, Cyclolam-pas). At the same time, the peristome of some genera was displaced to the anterior margin of the test, which became bilaterally symmetrical in outline. However, in the Jurassic, all spatangaceans remained disasterid echinoids, i.e., had a disjunct apical system, which can be interpreted as a somewhat “abnormal” state. This trend disappeared only at the beginning of the Cretaceous, when “normal” forms with a joint apical system appeared, that is, the families Holasteridae (genera Eoholaster and Holaster, order Holasteroida) and Toxas-teridae (genus Toxaster, order Spatangoida). Interesting examples of synchronous parallelism are provided by the appearance of meridosternous (diasternal) plastron in two collyritid genera (Tetraromania and Corthya) in the Barremian, whereas in the holasterid genus Holaster, this type of plastron apparently appeared in the Valanginian (heterochronous parallelism). The ethmolitic type of the apical system appeared at the end of the Cretaceous and Paleocene at least in five families: Schizasteridae, Paleopneustidae, Brissidae, Spatangidae, and Loveniidae.     

Low assimilation efficiency of photorespiratory ammonia in conifer leaves

Glutamine synthetase (GS) localized in the chloroplasts, GS2, is a key enzyme in the assimilation of ammonia (NH₃) produced from the photorespiration pathway in angiosperms, but it is absent from some coniferous species belonging to Pinaceae such as Pinus. We examined whether the absence of GS2 is common in conifers (Pinidae) and also addressed the question of whether assimilation efficiency of photorespiratory NH₃ differs between conifers that may potentially lack GS2 and angiosperms. Search of the expressed sequence tag database of Cryptomeria japonica, a conifer in Cupressaceae, and immunoblotting analyses of leaf GS proteins of 13 species from all family members in Pinidae revealed that all tested conifers exhibited only GS1 isoforms. We compared leaf NH₃ compensation point (γ_NH3) and the increments in leaf ammonium content per unit photorespiratory activity (NH₃ leakiness), i.e. inverse measures of the assimilation efficiency, between conifers (C. japonica and Pinus densiflora) and angiosperms (Phaseolus vulgaris and two Populus species). Both γ_NH3 and NH₃ leakiness were higher in the two conifers than in the three angiosperms tested. Thus, we concluded that the absence of GS2 is common in conifers, and assimilation efficiency of photorespiratory NH₃ is intrinsically lower in conifer leaves than in angiosperm leaves. These results imply that acquisition of GS2 in land plants is an adaptive mechanism for efficient NH₃ assimilation under photorespiratory environments.     

A phylogeny of Lophocoleaceae-Plagiochilaceae-Brevianthaceae and a revised classification of Plagiochilaceae

The Lophocoleaceae-Plagiochilaceae-Brevianthaceae clade is a largely terrestrial, subcosmopolitan lineage of jungermannialean leafy liverworts that may include significantly more than 1000 species. Here we present the most comprehensively sampled phylogeny available to date based on the nuclear ribosomal internal transcribed spacer region and the chloroplast markers rbcL and rps4 of 372 accessions. Brevianthaceae (consisting of Brevianthus and Tetracymbaliella) form a sister relationship with Lophocoleaceae; this lineage is in turn sister to Plagiochilaceae. Plagiochila is resolved monophyletic subsequent to exclusion of Plagiochila radiculosa; this species is placed in a new genus Cryptoplagiochila. Chiastocaulon and a polyphyletic Acrochila nest in Plagiochilion; these three genera are united under Chiastocaulon to include the Plagiochilaceae species with dominating or exclusively ventral branching. The generic classification of the Lophocoleaceae is still unresolved. We discuss alternative approaches to obtain strictly monophyletic genera by visualizing their consistence with the obtained consensus topology. The presented phylogeny will serve as a basis for follow-up studies including several thousand accessions. These studies will enable revision of current hypotheses on species diversity and distribution of Lophocoleaceae-Plagiochilaceae-Brevianthaceae and allow for a reconstruction of their evolution in time and space.     

Phylogeny and taxonomy of casebearer moths (Lepidoptera,Coleophoridae) based on morphological and molecular genetic data. 1. Reconstruction of phylogeny of coleophoridae using analysis of <Emphasis Type="Italic">COI</Emphasis> gene variability

A phylogenetic study of representatives of the family Coleophoridae was conducted using a comprehensive approach, including methods of morphological and molecular genetic analyses. The existent data on the family system were compared with the results of phylogenetic analysis of the COI mitochondrial gene sequences. Four of the five studied subfamilies (Coleophorinae, Ischnophaninae, Augasminae, and Tolleophorinae) corresponded to their location on the phylogram; representatives of Metriotinae were part of Coleophorinae. According to the aggregate data from molecular phylogeny and morphology, the most numerous subfamily of casebearers, Coleophorinae, is polyphyletic within its current boundaries. The results of our analysis of COI molecular divergence does not refute the monophyly of the tribes Casignetellini, Carpochenini, Klinzigedini, Goniodomini, Casasini, and Atractulini from the subfamily Coleophorinae. The allocation of the tribes Aporipturini and Sistrophoecini within the subfamily does not correspond to the molecular data. Monophyly of the genera Ecebalia, Perygra, and Casignetella was confirmed. These genera are well isolated, which reflects the evolutionary significance of the morphological characters chosen for their taxonomic division. The boundaries of the cluster containing these genera correspond to those of the tribe Casignetellini, justifying the allocation of this tribe within the subfamily. The existence of monophyletic tribes Goniodomini (genus Goniodoma) and Carpochenini (genera Ionescumia, Carpochena, and Falkmisa) was also supported. The exceptions were the genera Kasyfia, Tollsia, and Agapalsa, whose monophyly was not confirmed by our results. The distribution of the sequences of species of these genera indicated a paraphyletic origin of Kasyfia and Tollsia and a polyphyletic origin of Agapalsa.     

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.     

A checklist of Lecythidaceae in the upper Madeira River,Rondônia,Brazil with comments on diversity and conservation

The Lecythidaceae or Brazil Nut family are ubiquitous in non-flooded lowland forests of the Amazon, where they are indicative of well-preserved or little-disturbed habitats. A recent checklist of the Brazilian flora reported 10 genera and 119 species for that country, of which 104 are found in the Amazon region. However, the botanical knowledge in many regions of the country remains far from complete. This study aimed to analyze the diversity of Lecythidaceae in the upper Madeira River region in Rondônia, an area where botanical data is scarce. Lecythidaceae collections deposited in the CEN, INPA and RON herbaria were examined, and four field expeditions in the study area were carried out. For that region, we recorded 37 species of Lecythidaceae belonging to 7 genera: Eschweilera (21 species), Couratari (6), Cariniana (3), Gustavia (3), Allantoma (2), Bertholletia (1) and Lecythis (1). Among these species, five are listed as threatened in the IUCN Red List. The total number of species found in the upper Madeira River of Rondônia alone is higher than the 28 species reported to date for the entire state of Rondônia in the Brazilian Flora Checklist (Smith et al., 2015), and adds 13 new records of Lecythidaceae for the state. Considering that this study is restricted to the northern part of the state, our results suggest that the number of Lecythidaceae species in Rondônia is severely underestimated. Our findings highlight the need for more intensive floristic studies in the Amazon region, which should target areas that are botanically unexplored but have high biodiversity potential. Such studies will provide valuable information to support both taxonomic studies and species conservation assessments.     

Distribution and microsculpture of limnadiidae,falsiscidae, and glyptoasmussiidae (Conchostraca) of the terminal Permian of Siberia

New data on the distribution of conchostracans in volcanogenic deposits of the terminal Permian of the Tunguska Syneclise (Vyatkian and Taimyrian stages of the Tatarian Series) are presented. Based on the SEM study of these conchostracans their minute ornamentation patterns are described: microsculpture of Eulimnadia consisting of pits and cells with rounded cells separated by flattened interspaces, cellular microsculpture of Limnadia with rounded cells separated by convex interspaces (family Limnadiidae), honeycomblike cellular microsculpture of Falsisca (new family Falsiscidae), and microsculpture of Loxomicroglypta (?) consisting of small uniform rounded cells separated by narrow convex or angular interspaces (family Glyptoasmussiidae). The diagnoses of the genera and species are emended.     

Revision of the superfamily Acrotheloidea (Brachiopoda,class Linguliformea,order Lingulida) from the Lower and Middle Cambrian of the Siberian Platform

This paper continues our revision of Yu.L. Pelman’s collection of the superfamily Acrotheloidea (phosphatic brachiopods) and of our own material from the Early–Middle Cambrian of the Siberian Platform. The following representatives of the superfamily Acrotheloidea (order Lingulida, class Linguliformea) are restudied and revised based on new techniques: the genus Botsfordia (family Botsfordiidae Schindewolf, 1955) and the genera Acrothele, Eothele, and Orbithele (family Acrothelidae), which are widespread on the Siberian Platform. Only one out of the three Acrothele species described by Pelman is recognized as a valid species, and one new species of this genus that comprises some part of the brachiopods that Pelman figured and placed in another taxon is described. All these species are described using data on shell microsculpture and microstructure. In addition, the genera Eothele and Orbithele are described for the first time from the Siberian Platform.     

Resurrection and emendation of the Hypoxylaceae,recognised from a multigene phylogeny of the Xylariales

A multigene phylogeny was constructed, including a significant number of representative species of the main lineages in the Xylariaceae and four DNA loci the internal transcribed spacer region (ITS), the large subunit (LSU) of the nuclear rDNA, the second largest subunit of the RNA polymerase II (RPB2), and beta-tubulin (TUB2). Specimens were selected based on more than a decade of intensive morphological and chemotaxonomic work, and cautious taxon sampling was performed to cover the major lineages of the Xylariaceae; however, with emphasis on hypoxyloid species. The comprehensive phylogenetic analysis revealed a clear-cut segregation of the Xylariaceae into several major clades, which was well in accordance with previously established morphological and chemotaxonomic concepts. One of these clades contained Annulohypoxylon, Hypoxylon, Daldinia, and other related genera that have stromatal pigments and a nodulisporium-like anamorph. They are accommodated in the family Hypoxylaceae, which is resurrected and emended. Representatives of genera with a nodulisporium-like anamorph and bipartite stromata, lacking stromatal pigments (i.e. Biscogniauxia, Camillea, and Obolarina) appeared in a clade basal to the xylarioid taxa. As they clustered with Graphostroma platystomum, they are accommodated in the Graphostromataceae. The new genus Jackrogersella with J. multiformis as type species is segregated from Annulohypoxylon. The genus Pyrenopolyporus is resurrected for Hypoxylon polyporus and allied species. The genus Daldinia and its allies Entonaema, Rhopalostroma, Ruwenzoria, and Thamnomyces appeared in two separate subclades, which may warrant further splitting of Daldinia in the future, and even Hypoxylon was divided in several clades. However, more species of these genera need to be studied before a conclusive taxonomic rearrangement can be envisaged. Epitypes were designated for several important species in which living cultures and molecular data are available, in order to stabilise the taxonomy of the Xylariales.     

Diversity and eco-zoogeographic analysis of lamellicorn beetles (Coleoptera,Scarabaeoidea) of Yakutia,Russia

A comprehensive analysis of the diversity of Yakutian lamellicorn beetles is provided. A total of 54 species from 18 genera, 14 tribes, 14 subfamilies, and 5 families are revealed. The family Ochodaeidae Mulsant & Rey, 1871, the genus Codocera Eschscholtz, 1821, and six species, namely Codocera ferruginea (Eschscholtz, 1818), Aegialia friebi Balthasar, 1935, A. kamtschatica Motschulsky, 1860, Aphodius ater (De Geer, 1774), A. pusillus Herbst, 1789, and A. haemorrhoidalis (Linnaeus, 1758), are recorded in the fauna of Yakutia for the first time. The ecological and zoogeographic features of the Scarabaeoidea of the region are considered. Data on the trophic specialization, phenology and spatial distribution of the species are given.
