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.  相似文献

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.  相似文献

Weitschataster intermedius gen. et sp. nov., is described from the Upper Campanian (Upper Cretaceous) of Hannover (Lower Saxony, N Germany). The new species is characterized by its conspicuous rimmed pedicellariae scars covering almost the complete actinal surface and by small body size. W. intermedius represents a transitional state between W. decipiens comb. nov. from the Lower Campanian and the well-known W. undulatus comb. nov. from the Lower Maastrichtian of NW Europe. Among Spencer’s types of W. undulatus, one paratype is recognized as belonging to the genus Parametopaster.  相似文献

Fossil leaves and associated reproductive structures from the Kundur locality, Amur Region, are examined. A new genus of the unlobed platanaceous leaves, Kunduriphyllum gen. nov. (Platanaceae) is described based on distinctive morphological and epidermal features. The similarity of epidermal characteristics and identical biological damage suggest that the leaves Kunduriphyllum kundurense gen. et comb. nov., staminate inflorescences Kundurianthus, and infructescences Kunduricarpus could be assigned to a single plant.  相似文献

Two new genera (monotypic Samarabatrachus gen. nov. (S. bjerringi sp. nov.) and Syrtosuchus gen. nov. (including S. samarensis (Sennikov, 1981) and S. morkovini sp. nov) and a new species of the genus Selenocara Bjerring (S. rossica sp. nov.) are described based on revision of the original material of the form previously known as Wetlugasaurus samarensis. The genera Selenocara and Samarabatrachus gen. nov. positioned at the base of radiation of Triassic capitosaurids are combined into a new subfamily, Selenocarinae subfam. nov. The genus Syrtosuchus gen. nov., which is undoubtedly a derivative of early capitosaurids (Selenocara or a closely related genus), shows some typical benthosuchid features and is assigned to a separate benthosuchid subfamily, Syrtosuchinae subfam. nov. The diagnoses of the genera Wetlugasaurus Riabinin and Selenocara are amended. For the territory of the Obschii Syrt Highland, the genera Selenocara, Samarabatrachus gen. nov., and Syrtosuchus gen. nov. are regarded as key members of a separate Early Triassic tetrapod assemblage (Selenocara–Syrtosuchus Fauna), which is intermediate between the Tupilakosaurus and Benthosuchus faunas and dated Late Induan (Dienerian).  相似文献

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.  相似文献

Ant imprints, new and previously known, from Middle Miocene deposits near Kerch (Crimean Peninsula, Russia) are described or redescribed. A new Myrmicinae species, Solenopsis atavinus sp. nov., is described based on a wingless female. A winged female similar to the earlier described Dolichoderus tauricus Dlussky, 1981 is found: due to the excellent preservation of this specimen, the new specimen and the holotype of D. tauricus are redescribed and can be reclassified as Ponerites tauricus (Dlussky, 1981), comb. nov. Oecophylla taurica sp. nov. is described based on a partly preserved imprint of a female thorax with a forewing, the venation of which allows it to be positively identified as a weaver ant. Two other species are transferred from the formal genus Camponotites to Oecophylla based on forewing venation: O. kraussei (Dlussky et Rasnitsyn, 1999), comb. nov. (Early Eocene, United States) and O. macroptera (Dlussky, 1981), comb. nov. (Middle Miocene, Stavropol, Russia). One of the studied forewing imprints is similar in venation to Paraphaenogaster microphthalmus Dlussky, 1981, described from the Middle Miocene of Vishnevaya Balka (Stavropol province, Russia) and so is attributed to this species. Dolichoderus tavridus sp. nov. is described based on a forewing.  相似文献

Two new genera and three new species of soft-winged flower beetles (Coleoptera, Malachiidae) are described from Rovno and Baltic Eocene amber. Protocephaloncus gen. nov. with the type species P. perkovskyi sp. nov. was found in the Rovno amber. It differs from its congeners in the tribe Troglopini in the primitive sculpture of the male facial area as a longitudinal narrow depression between the eyes lacking an appendage inside, and two trapezoid impressions on both sides of the depression closer to its lower part. A transverse pronotum, slightly rounded, but not sinuate posteriorly, is also a diagnostic feature of the new genus. A new genus of the tribe Attalini, Palpattalus gen. nov., was found in the Baltic amber. The tarsal comb on the anterior second tarsomere of the male, complicatedly curved pygidium, and cylindrical apical palpomere allow the definite attribution of the genus to the tribe Attalini. The characteristically enlarged, rounded and slightly flattened 1st palpomere, possessing a long seta directed outward, of the new genus resembles similar structures found in members of the tribe Colotini, all males of which have modified and enlarged 3rd and 4th palpomeres. Probably, Palpattalus gen. nov. represents an ancestral form for these two tribes. This allows the establishment of independent status for Antholinus Mulsant and Rey, 1867 stat. resurr., with anterior tarsi in males lacking comb on the second tarsomere, in contrast to all other subgenera of Attalus Erichson, 1840. Males of two different species, Palpattalus baltiensis sp. nov. and P. eocenicus sp. nov., were found as inclusions in Baltic amber. They differ in the coloration of the elytra, yellow with black spots in Palpattalus baltiensis sp. nov. and unicolorous black in P. eocenicus sp. nov.; the shape of pygidia, longitudinal and strongly elongated in P. baltiensis and transverse and rounded in P. eocenicus, and in a number of other characters.  相似文献

The nymphalid Paulogramma hydarnis (Godart) (n. comb., previously in the genus Callicore) is an endangered butterfly present in a few montane sites in the Atlantic Forest in the Southeastern Brazil. The precise systematic position of P. hydarnis was previously unknown. Based on molecular data, we find that it is sister to Paulogramma pygas (Godart) (n. comb., also previously in Callicore), a common and widespread species in the Neotropics. In addition, we find that Callicore is not monophyletic and that “Callicorehydarnis (along with other species) is more related to the genus Paulogramma, and should thus be placed in that genus. The genus Paulogramma is now composed by the following species: Paulogramma pyracmon (Godart), Paulogramma eunomia (Hewitson) n. comb., Paulogramma hydarnis (Godart) n. comb., Paulogramma hystaspes (Fabricius) n. comb., Paulogramma pygas (Godart) n. comb., and Paulogramma tolima (Hewitson, 1852) n. comb. Museum specimens and field data report P. hydarnis in four sites in Southeastern Brazil. Recently, P. hydarnis was recorded for the first time at Parque Nacional do Caparaó, states of Espírito Santo and Minas Gerais, expanding its distribution about 200 km northward of the previously known limit. Although regularly recorded in some sites, most records are historic, before the 1960s, and the current conservation situation of this species is delicate, deserving attention.  相似文献

A new genus, Tologuica, with two species (T. aurorae sp. nov. and T. karhui sp. nov.), from the Middle Miocene of the Sharga locality (western Mongolia) is described. The new genus shares some characters with the extinct genera Palaeocryptonyx, Palaeortyx, and Plioperdix and with extant Coturnix. The foot structure suggests that Tologuica resembled in ecology the European genus Palaeortyx and was probably adapted to an arboreal mode of life, in contrast to the terrestrial Coturnix and Plioperdix.  相似文献

This study focuses on the former Verticillium section Albo-erecta that included white or whitish species with verticillium-like, erect conidiophores. Its type species was Verticillium fungicola, which was transferred to Lecanicillium, a genus that otherwise contains species with prostrate conidiophores. Phylogenetic analysis of ITS, 18S and 28S rDNA sequences revealed that this group is heterogeneous and its members belong to at least three families. The present study is a first step to its resolution. Supported by analyses of 68 sequences of ITS, 23 sequences of 18S and 43 sequences of 28S ribosomal DNA, the species are distributed over three families. In the Cordycipitaceae, Leptobacillium gen. nov. is described with L. leptobactrum comb. nov. and its new variety, calidius. In the Hypocreaceae, Hypomyces is treated with one new combination from former Nectriopsis, H. tubariicola, and two new anamorphic species, H. ellipsosporus and H. subglobosus; in Sphaerostilbella, one new anamorphic species, S. parabroomeana, is described. In the Bionectriaceae, anamorphic isolates of Nectriopsis requiring a new combination, N. lindauiana, and a new species, N. fuliginicola, are described. Parsimony analysis of the LSU suggests that Ovicillium gen. nov. with four new species, O. attenuatum, O. oosporum, O. subglobosum and O. napiforme, is a member of the Bionectriaceae by 93 % bootstrap support. Of uncertain family classification are Chlamydocillium gen. nov. with one new soil-borne species, C. cyanophilum, and Chlorocillium gen. nov. based on Acremonium griseum Petch. A few further white verticillium-like anamorphs, particularly V. biguttatum, could not yet be reclassified.  相似文献

The heteromorph ammonites of the family Bochianitidae from the Lower Cretaceous of the Crimean Mountains are revised. The validity of the genus Janenschites, separated from the genus Bochianites is confirmed. The species Bochianites neocomiensis (d’Orbigny), B. goubechensis Mandov, B. levis sp. nov. and B. crymensis sp. nov. are described from the Berriasian and the species Janenschites oosteri (Sarasin et Schöndelmayer) and J. incisus sp. nov. are described from the Lower Barremian. The family Bochianitidae first appeared at the beginning of the Berriasian in the southern regions (Africa and the Crimea), and spread to the northern regions of western Europe in the Valanginian-Hauterivian.  相似文献
