Some New Species of <Emphasis Type="Italic">Crassatella</Emphasis> (Bivalvia) from the Upper Eocene of Ukraine

Three new bivalve species of Crassatella (C. necopina sp. nov., C. personata sp. nov., C. singulata sp. nov.) from detrital sand of the Rybal’sky quarry of Dnepropetrovsk are described. Based on the study of additional material, the subspecies C. (C.) parisiensis Orbigny duplex Berezovsky, 2004 is ranked species (Upper Eocene; Ukraine Dnepropetrovsk, Rybal’sky quarry, Mandrikovka Beds).     

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.     

New species of the pelecypod genus <Emphasis Type="Italic">Crassatella</Emphasis> (Bivalvia) from the Upper Eocene of Dnepropetrovsk,Ukraine

Two new species of the genus Crassatella, C. imitatoris sp. nov. and C. pseudolamellosa sp. nov., from Upper Eocene detrital sands of the Rybal’sky quarry of Dnepropetrovsk are described. The species Crassatella oblongula Klushnikov, 1958 is redescribed as a variety.     

New species of the buprestid genus <Emphasis Type="Italic">Endelus</Emphasis> Deyrolle (Coleoptera,Buprestidae) from China,India, and Laos

Endelus (Kubaniellus) indicus sp. n. from India, E. (K.) lao sp. n. and E. (K.) khnzoriani sp. n. from Laos, E. (s. str.) sausai sp. n. from China, and E. (s. str.) dembickyi sp. n. from India are described, the two latter species are included in the Endelus bicarinatus Théry, 1932 species-group recently established by the author. E. collinus Obenberger, 1922 is included in this group; lectotype of this species is designated. Keys to species of the subgenus Kubaniellus and of the E. collinus group are provided. E. (K.) kareni Kalashian is for the first time recorded for Shaanxi Prov., E. pacholatkoi Kalashian, E. smaragdinus Desc. et Vill., and E collinus Obenb., for Laos (the latter species, also for Myanmar).     

Taxonomic revisions in the Microstromatales: two new yeast species,two new genera,and validation of <Emphasis Type="Italic">Jaminaea</Emphasis> and two <Emphasis Type="Italic">Sympodiomycopsis</Emphasis> species

Environmental sampling yielded two yeast species belonging to Microstromatales (Exobasidiomycetes, Ustilaginomycotina). The first species was collected from a leaf phylloplane infected by the rust fungus Coleosporium plumeriae, and represents a new species in the genus Jaminaea, for which the name Jaminaea rosea sp. nov. is proposed. The second species was isolated from air on 50% glucose media and is most similar to Microstroma phylloplanum. However, our phylogenetic analyses reveal that species currently placed in Microstroma are not monophyletic, and M. phylloplanum, M. juglandis and M. albiziae are not related to the type species of this genus, M. album. Thus, Pseudomicrostroma gen. nov. is proposed to accommodate the following species: P. glucosiphilum sp. nov., P. phylloplanum comb. nov. and P. juglandis comb. nov. We also propose Parajaminaea gen. nov. to accommodate P. albizii comb. nov. and P. phylloscopi sp. nov. based on phylogenetic analyses that show these are not congeneric with Jaminaea or Microstroma. In addition, we validate the genus Jaminaea, its respective species and two species of Sympodiomycopsis and provide a new combination, Microstroma bacarum comb. nov., for the anamorphic yeast Rhodotorula bacarum. Our results illustrate non-monophyly of Quambalariaceae and Microstromataceae as currently circumscribed. Taxonomy of Microstroma and the Microstromataceae is reviewed and discussed. Finally, analyses of all available small subunit rDNA sequences for Jaminaea species show that J. angkorensis is the only known species that possess a group I intron in this locus, once considered a potential feature indicating the basal placement of this genus in Microstromatales.     

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.     

To the knowledge of oribatid mites of the genus <Emphasis Type="Italic">Nothrus</Emphasis> (Acari,Oribatida, Nothridae) from Taiwan

Two species of oribatid mites of the genus Nothrus (Oribatida, Nothridae) were collected during an expedition to Taiwan in 2017. The species Nothrus anauniensis Canestrini and Fanzago, 1876 is redescribed and illustrated in detail; the main morphological traits for this species are summarized. A new species Nothrus xuejianensis Ermilov sp. n. is described; it differs from the closest species, Nothrus meakanensis Fujikawa, 1999 by the morphology and length of notogastral setae h₂ and number of subcapitular setae m.     

New bryozoans (Stenolaemata) from the Middle Jurassic of Moscow City and the Moscow Region

Five new species of stenolaematous bryozoans are described from the Middle Callovian of Moscow City (Krasnopresnenskii Region) and the Moscow Region (Gzhel’ Railroad Station and the quarry between the small towns of Rechitsy and Troshkovo): Entalophora alexeevi sp. nov., Cellulipora retshitsiensis sp. nov., Diplosolen pravus sp. nov., Siphodictyum primarium sp. nov., and Ceata kamushkiensis sp. nov. The last four species belong to the genera that have never been recorded from deposits older than the Lower Cretaceous. The presence of different types of heterozooecia in these bryozoans shows that the functional polymorphism of zooids developed considerably in the class Stenolaemata as early as the Middle Jurassic.     

Findings of the leaf beetles <Emphasis Type="Italic">Chrysolina tundralis</Emphasis> and <Emphasis Type="Italic">Chrysolina roddi</Emphasis> (Coleoptera,Chrysomelidae) in the middle part of European Russia

Two species of leaf beetles, Chrysolina tundralis and Ch. roddi, were found in the “Galich’ya Gora” Nature Reserve (the middle part of European Russia), 1200 and 700 km, respectively, from the main part of the ranges of these species. Adults and larvae of Ch. tundralis feed on Lamium purpureum, those of Ch. roddi feed on Seseli intermedia there. Diagnostic characters of the adults of both species are reported.     

Evolutionary relationships in the genus <Emphasis Type="Italic">Secale</Emphasis> revealed by DArTseq DNA polymorphism

Till this day, there is not much known about the phylogeny of the Secale genus; therefore, in our research, we tried to shed some lights on the issue of rye (Secale genus) taxonomy. The genetic diversity and phylogenetic relationships were evaluated using 13,842 DArTseq? polymorphic markers. The model-based clustering (STRUCTURE software) separated our 84 samples into three main clusters: perennial cluster, annual cluster, and S. sylvestre cluster. The same result was obtained using Neighbour Joining tree and self-organizing maps. Secale sylvestre, S. strictum, and S. cereale are the three main species of the Secale genus. Three samples of rye are in basal positions in phylogenetic trees. These accessions share ancient morphological characters and are probably the ancestors of different lineages within Secale. Annual Secale taxa, with the exception of S. sylvestre, create one mutual taxon. We have found out that the semi-perennial taxa of S. cereale var. multicaule and S. strictum subsp. ciliatoglume are genetically closest to the annual species of S. cereale. Phylogenetic signals for semi-perennial and annual taxa are also present in S. strictum subsp. africanum. SNP-based analysis revealed that evolution of annual S. cereale has already begun in S. strictum subsp. africanum. The results showed that S. vavilovii cannot be considered as a separate species but a subspecies of S. cereale Secale cereale subsp. dighoricum is a hybrid. It is still not clear whether we can consider S. strictum subsp. strictum and S. strictum subsp. kuprijanovii as two separate species.     

A global survey of <Emphasis Type="Italic">Puccinia</Emphasis>-rust on Cucurbitaceae

In this paper, all known autoecious Puccinia species (rust fungi, Uredinales) on Cucurbitaceae are described and most of them illustrated. A key and information on their host range and distribution is presented. Four species, Puccinia antennata, P. arbor-miraculensis, P. hieroglyphica, and P. rhytidioderma are proposed as new. P. momordicae and P. trochomeriae are recognised as valid species different from P. cephalandrae. Uredo melothriae is a new combination for Uromyces melothriae. P. cucumeris is a new report for Namibia, P. momordicae for Zimbabwe and P. vanderystii for Kenya. The species appear to be host specific with regard to host tribes, but P. citrulli and P. cucumeris may pass tribal boundaries. Most species are morphologically very similar and are characterised by a unique set of teliospore characters. They are therefore regarded as a natural group. The distribution of this group in semiarid habitats, mainly from southern Africa to India, is discussed.     

A RAPD fingerprinting of sibling species of the <Emphasis Type="Italic">Drosophila virilis</Emphasis> group

A comparative analysis of the sibling species of Drosophila virilis was performed by RAPD-PCR technique using a set of random primers. The degree of relatedness was studied by cluster analysis (UPGMA) and multidimensional scaling. The resulting pattern of species relationships contradicts the classical taxonomy. The main result of the cluster analysis is that D. virilis does not cluster with the remaining three species of its phylad, while according to multidimensional scaling, D. virilis is equidistant from all the species of its group, from both the species of its phylad and the species of the montana phylad. The montana phylad is extremely heterogeneous; moreover, the species D. littoralis, D. ezoana, and D. kanekoi appear to be closer to the virilis phylad than to the other species of the montana phylad, wherein these species are traditionally included. The phylogenetic relationships between the studied species discovered using RAPD fingerprinting comply with the results obtained using protein markers and quantitative traits.     

Polyphasic characterisation of three novel species of <Emphasis Type="Italic">Paraboeremia</Emphasis>

Paraboeremia was recently introduced for a distinct lineage in the family Didymellaceae. Currently, three species are included, i.e. P. adianticola, P. putaminum and P. selaginellae, all of which are plant pathogens. Paraboeremia is morphologically similar to Phoma but phylogenetically distinct. In this paper, three new species, i.e. Paraboeremia camelliae isolated from Camellia sp., P. litseae from Litsea sp., and P. oligotrophica from cave limestone, are described, illustrated and compared with closely related taxa. Phylogenetic analysis based on the multi-locus sequences of the internal transcribed spacer regions 1 and 2 and 5.8S nuclear ribosomal RNA gene (ITS), partial large subunit 28S nrDNA region (LSU), partial β-tubulin (TUB2) gene and RNA polymerase II (RPB2) gene regions confirmed the distinction of these species in Paraboeremia. These three new species were discovered from habitats and hosts that are previously unknown from this genus.     

A Survey of the Distribution and Phylogenetic Relationships of the <Emphasis Type="Italic">Silvestrichilis</Emphasis> Group of Genera and of the Species of the Genus <Emphasis Type="Italic">Silvestrichilis</Emphasis> Wygodz. (Archaeognatha,Machilidae) with Description of a New Species from South Ossetia

Review of the six genera of the Silvestrichilis group (Dilta Strand, Haslundiella Janetschek, Silvestrichilis Wygodzinsky, Silvestrichiloides Mendes, Haslundichilis Wygodzinsky, and Himalayachilis Wygodzinsky) and of the 17 species of the southern Palaearctic genus Silvestrichilis was performed for the first time with a discussion of their phylogenetic relationships and evolutionary trends based on comparative analysis of the geographic distribution of the species and of the distribution of plesiomorphic and apomorphic states of their main morphological features. Haslundichilis quadrii Wygodzinsky, 1952 from northwestern India and H. lindbergi Wygodzinsky, 1962 from western Afghanistan are transferred to the genus Haslundiella, and new combinations Haslundiella quadrii (Wygodzinsky, 1952), comb. n. and Haslundiella lindbergi (Wygodzinsky, 1962), comb. n. are established. A new species, Silvestrichilis polinaesp. n., differs from all the congeners in the strongly dilated fore femur of the male and female, in the maxillary palpus chaetotaxy, and in the structure of the sensory field on the fore femur of the male.     

A review of the buprestid genus <Emphasis Type="Italic">Cochinchinula</Emphasis> Volk. With description of new taxa from Thailand,and notes on the composition and classification of the tribe Acmaeoderini (Coleoptera,Buprestidae, Polycestinae)

A review of the Oriental genus Cochinchinula Volk. (Coleoptera, Buprestidae, Polycestinae, Acmaeoderini) comprising three species is presented. The new species C. thailandica and C. bilyi spp. n. and the new genus Thaichinula gen. n. (type species T. ohmomoi sp. n.) from Thailand are described. A key to species of the genera Cochinchinula and Thaichinula is provided. The Nearctic genus Paracmaeoderoides Bellamy and Westcott is transferred from the subtribe Nothomorphina to the subtribe Acmaeoderoidina, and the South African genus Richtersveldia Bellamy is transferred from the subtribe Nothomorphina of Acmaeoderini to the tribe Ptosimini. The generic status is restored for another South African genus, Brachmaeodera Volkovitsh and Bellamy. The main evolutionary trends are discussed, and the taxonomic composition and classification of the tribe Acmaeoderini are clarified.     

<Emphasis Type="Italic">Neocosmocercella fisherae</Emphasis> n. sp. (Nematoda: Cosmocercidae), a parasite of the large intestine of <Emphasis Type="Italic">Phyllomedusa bicolor</Emphasis> (Boddaert) (Anura: Phyllomedusidae) from the Brazilian Amazon

Neocosmocercella fisherae n. sp. is the first nematode species found parasitising Phyllomedusa bicolor from the Brazilian Amazon Region. The new species has a triangular oral opening, with bi-lobed lips, and is distinguished from N. bakeri (triangular oral opening with simple lips), and from N. paraguayensis (hexagonal oral opening with bi-lobed lips). Additionally, the new species has ciliated cephalic papillae, which are absent in the other species of the genus. The reduced uterine sac and the presence of a single egg in the uterus in females are the main morphological characters that differentiate the new species from its congeners N. bakeri (8–10 eggs) and N. paraguayensis (10 eggs, based on the allotype). Additionally, the new species differs from the other two species of the genus by morphometric characters such as the size of spicules and gubernaculum in males and the vagina in females. Until now, phyllomedusid anurans are the only known hosts for the nematodes of this genus. The present work describes the third species of the genus and the first species of nematode parasitising P. bicolor.     

<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
