On new Jurassic Rissooidea and Zygopleuroidea convergently similar to them (Gastropoda: Pectinibranchia)

A new genus, Boreomica gen. nov., is established; it comprises small-sized gastropods widespread in the Jurassic of the Russian Plate, the taxonomic position of which was ambiguously treated by previous authors. The new genus is assigned to the family Rissoidae. The species composition and stratigraphical and geographical distribution of the genus and its species are discussed. From the Jurassic of the Russian Plate, Callovian Boreomica exigua (Gerasimov, 1992), the type species of the genus, and Kimmeridgian–Volgian Boreomica undulata (Tullberg, 1881), and members of the genus without species status from the Bathonian and Upper Oxfordian are described. Conchological polymorphism of species connected with their eurybiontic characteristics is discussed. Based on the study of samples of the species B. exigua from different types of facies, two subspecies are recognized, B. exigua exigua and B. exigua arenosa subsp. nov. Finds of gastropods morphologically similar to Boreomica are discussed: Katosira? sp. from Mitta et al., 2004, “Procerithium?” volgense Gerasimov, 1955, “Eulima” pusilla Tullberg, 1881, and “Hudlestonella” caleptra sensu Gerasimov, 1992 are considered. It is concluded that E. pusilla and H. caleptra are unknown zygopleurids, Katosira? sp. is likely a poorly preserved Katosira, and “Procerithium?” volgense is represented by a mixture of several species belonging to different genera: several zygopleurid species, the rissoids Boreomica undulata and Bralitzia. Shells of P. volgense in the P.A. Gerasimov’s collection from the Craspedites nodiger Zone are described as Laevipleura sp.     

Redescription of a fossil loach <Emphasis Type="Italic">Triplophysa opinata</Emphasis> (Yakowlew, 1959) from the Miocene of Kirgizia (Balitoridae: Nemacheilinae)

The only known fossil representative of the genus Triplophysa, T. opinata from the middle-upper Miocene of Kirgizia is redescribed. It is suggested that this species is closest to the species groups “dorsalis” and “labiata” (sensu Prokofiev, 2002, 2004a). The fossil finding clearly suggests that Triplophysa developed no later than in the middle of the Neogene.     

Notes on the phylogenetic relationships of planthoppers of the family issidae (Hemiptera,Fulgoroidea) of the Western Palaearctic fauna,with descriptions of two new genera

Seven groups of genera are distinguished in the subtribe Issina Spinola. The new genera Apedalmus gen. n. (the type species Falcidius abruzicus Dlabola, 1983) and Thalassana gen. n. (the type species: Hysteropterum ephialtes Linnavuori, 1971) are erected. The subgenera Acrestia Dlabola, 1980, Montissus Gnezdilov, 2003, and Atticus Gnezdilov, 2003 are upgraded to genera. The subgenus Capititudes Gnezdilov, Drosopoulos et Wilson, 2004 is transferred to the genus Acrestia, and the subgenus Stygiata Emeljanov, 1972 to Celyphoma Emeljanov, 1971. The subtribe Agalmatiina Gnezdilov, 2002 and the subfamily Hysteropterinae Melichar, 1906 are placed in synonymy under Issina Spinola, 1839. Issus reticulatus Herrich-Schäffer, 1835 is designated as the type species of the genus Hysteropterum Amyot et Serville, 1843.     

New and little known crickets of the subfamily phalangopsinae (Orthoptera,Gryllidae): 5. Neotropical taxa of the tribe Paragryllini

One new genus, two new subgenera, and eight new species from Ecuador, Brazil, and Venezuela are described. The former genus Hattersleya Nischk et Otte is considered as a subgenus of the genus Neoacla Des. Acla multivenosa Chop., A. reticulata Chop., A. vicina Chop., Selvacla choreutes Otte, S. salvator Otte, S. alsiosus Otte, and S. sophos Otte are transferred to the genus Neoacla, and Desutteria epiplatys Nischk et Otte, to the genus Silvastella Des.-Gr. New data on the geographical and ecological distribution of some species are given.     

Revision of the genus <Emphasis Type="Italic">Melamphaes</Emphasis> (Melamphaidae): 6. oligo-raker species: <Emphasis Type="Italic">M. papavereus,M. simus,M. hubbsi</Emphasis>

Three oligo-raker species (≤19 rakers on the first gill arch) of the genus Melamphaes have been considered. A new species, M. papavereus, out of the group “M. typhlops” has been described from the Bay of Bengal of the Indian Ocean. M. simus and M. hubbsi out of the group “M. simus” have been revised. M. simus inhabits all oceans between 40° N and 40° S. M. hubbsi has been known from single specimens caught in the central part of the South Atlantic between 11° and 19° S.     

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.     

A new Species of <Emphasis Type="Italic">Ceratozamia</Emphasis> (Zamiaceae) from the Sierra Norte of Puebla,Mexico

Recent collections of Ceratozamia from the Sierra Norte of Puebla, Mexico, point to a new undescribed species, which was previously subsumed under the concept of C. mexicana. Identification of this new species resulted from a review of three associated species: C. mexicana, C. tenuis, and C. delucana. Here we describe Ceratozamia totonacorum and provide information regarding its distribution and natural history. The Ceratozamia species from the Sierra Madre Oriental, Mexico, are circumscribed using morphological characters, including a detailed evaluation of reproductive structures such as the apex, position, color and shape of the ovulate strobilus.     

A Review of the Fauna of the Planthopper Family Lophopidae (Homoptera,Fulgoroidea) from Vietnam with Descriptions of New Genera and Species and with Taxonomic Notes

Six new species are described from Vietnam, Apia simplexsp. n., Bisma angulatasp. n., Pitambara trypetoidessp. n., Sarmatoca cathemerinagen. et sp. n., Maracota soulieraegen. et sp. n., and Serida castaneasp. n., and Zeleja thoracalissp. n. from Malaysia. Two new genera, Maracotagen. n. (type species M. soulierae sp. n.) and Sarmatocagen. n. (type species S. cathemerina sp. n.), and a new subgenus Zelomachasubgen. n. (type species Zeleja thoracalis sp. n.) in the genus Zeleja are erected. The genus Binaluana Soulier-Perkins et Stroiński is downgraded to a subgenus of Zeleja Melichar. The genus Silvispina Wang et Soulier-Perkins with an uncertain systematic position is attributed to the subfamily Lophopinae and the tribe Lophopini. The placement of the genus Elasmoscelis Spinola (and, correspondingly, the tribe Elasmoscelini) in the subfamily Menoscinae, the genus Epiptyxis Gerstaecker in the tribe Menoscini, and the genus Jivatma Melichar in the tribe Lophopini is substantiated. New records of 11 species are given from Vietnam, some being first records for this country.     

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.     

High-throughput sequencing of <Emphasis Type="Italic">Prunus ferganensis</Emphasis> indicates that it is a geographical population of <Emphasis Type="Italic">P. persica</Emphasis>

Peach belongs to the genus Prunus, which includes Prunus persica and its relative species, P. mira, P. davidiana, P. kansuensis, and P. ferganensis. Of these, P. ferganensis have been classified as a species, subspecies, or geographical population of P. persica. To explore the genetic difference between P. ferganensis and P. persica, high-throughput sequencing was used in different peach accessions belonging to different species. First, low-depth sequencing data of peach accessions belonging to four categories revealed that similarity between P. ferganensis and P. persica was similar to that between P. persica accessions from different geographical populations. Then, to further detect the genomic variation in P. ferganensis, the P. ferganensis accession “Xinjiang Pan Tao 1” and the P. persica accession “Xia Miao 1” were sequenced with high depth, and sequence reads were assembled. The results showed that the collinearity of “Xinjiang Pan Tao 1” with the reference genome “Lovell” was higher than that of “Xia Miao 1” and “Lovell” peach. Additionally, the number of genetic variants, including single nucleotide polymorphisms (SNPs), structural variations (SVs), and the specific genes annotated from unmapped sequence in “Xia Miao 1” was higher than that in “Xinjiang Pan Tao 1” peach. The data showed that there was a close distance between “Xinjiang Pan Tao 1” (P. ferganensis) and reference genome which belong to P. persica, comparing “Xia Miao 1” (P. persica) and reference ones. The results accompany with phylogenetic tree and structure analysis confirmed that P. ferganensis should be considered as a geographic population of P. persica rather than a subspecies or a distinct species. Furthermore, gene ontology analysis was performed using the gene comprising large-effect variation to understand the phenotypic difference between two accessions. The result revealed that the pathways of gene function affected by SVs but SNPs and insertion-deletions markedly differed between the two peach accessions.     

Revision of the carabid genus <Emphasis Type="Italic">Meroctenus</Emphasis> Gemminger et Harold,with a new status of <Emphasis Type="Italic">Xenodochus</Emphasis> Andrewes (Coleoptera,Carabidae: Harpalini)

Originally described as a monotypical genus with unclear taxonomic position from Sudan, Meroctenus Gemminger et Harold, 1868 is treated as a polytypical genus of the Selenophori genus group with two subgenera: Meroctenus s. str. and Xenodochus Andrewes, 1941, stat. n. (the latter was previously considered a distinct genus). Within Meroctenus, two species are recognized: M. (Meroctenus) crenulatus Chaudoir, 1843 (type species) and M. (M.) mediocris (Andrewes, 1936), comb, n., transferred to Meroctenus s. str. from Xenodochus. A new subspecies M. (M.) crenulatus orientalis subsp. n. is described from Pakistan. Diagnoses of the genus Meroctenus in new interpretation as well as of its two subgenera are discussed, and a taxonomic review of the subgenus Meroctenus s. str. with a key to the species and subspecies is provided. The following synonymy is proposed: Meroctenus Gemminger et Harold, 1868 = Paregaploa Müller, 1947, syn. n.; Meroctenus crenulatus (Chaudoir, 1843) = Egaploa (Paregaploa) conviva Müller, 1947, syn. n. Lectotypes are designated for Ctenomerus crenulatus Chaudoir, 1843 and Xenodus mediocris Andrewes, 1936.     

Phylogeny and morphology of the <Emphasis Type="Italic">Peziza ammophila</Emphasis> complex (Pezizales,Ascomycota), with description of two new species and a new form

This study was focused on species of Peziza belonging to the “P. ammophila” complex, using both morphological and molecular approaches. Molecular and morphological analyses showed that several taxa are hidden under the name “ammophila” and, as a consequence, two additional species and one form are established: P. hellenica sp. nov., P. oceanica sp. nov. and P. ammophila f. megaspora f. nov. On the basis of the data that we have, these taxa seem to be related to some geographical areas; P. ammophila appears to be prevalent in northern, central and southern Europe, its f. megaspora is distributed in France and in the Netherlands, P. hellenica comes from Greece and P. oceanica from New Zealand. A cryptic species, not yet circumscribed satisfactorily, is described as P. deceptiva ad int. Moreover, the problem concerning the identification of P. ammophila is raised, the species is epitypified with a sequenced collection from Sicily (Italy) and a key to the species of the complex is provided.     

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.     

A new genus of African Lasiocampidae (Lepidoptera)

The species Gastroplakaeis idakum Bethune-Baker, 1913, G. balia Tams, 1929, and G. elongata Hering, 1941 are transferred from the genus Gastroplakaeis Möschler, 1887 into the newly erected genus Weirdonia gen. n. (the type species is Gastroplakaeis idakum Bethune-Baker, 1913), and corresponding new combinations are established. New species, Weirdonia baccara sp. n. and W. hypocrita sp. n. (type locality: Democratic Republic of the Congo), W. murena sp. n. (type locality: Northern Nigeria), and W. helicea sp. n. (type locality: Gabon) are described. A new synonymy is established: Gastroplakaeis balia Tams, 1929 = Gastroplakaeis elongata Hering, 1941 syn. n. Diagnoses and distribution maps are given for all the species.
