HYDE, K. D., 1992. Fungi from decaying fronds of Nypa fruticans, including three new genera and four new species. Decaying fronds and exposed stems of the mangrove palm Nypa fruticans were collected from beaches and intertidal regions of mangroves in Brunei and examined for the presence of higher marine fungi. Forty-three species were identified, four of which are new to science. The fungi included 32 Ascomycotina, one Basidiomycotina and ten Deuteromycotina. Three new genera and four new species are described and illustrated.  相似文献

Abstract Eight families of Symphyta for the Western Hemisphere south of the United States are reviewed: Xyelidae (one genus, two species), Pamphiliidae (one genus, four species), Cimbicidae (five genera, nine species), Diprionidae (three genera, thirteen species), Xiphydriidae (four genera, seventeen species), Siricidae (six genera, nine species), Orussidae (five genera, twelve species), and Cephidae (one genus, one species). New taxa are Acantholyda nigrostigmata (Pamphiliidae); Zadiprionfalsus, Neodiprion bicolor, N.equalis, N.omosus (Diprionidae); Derecyrta circularis, Steirocephala lateralba (Xiphydriidae); Sirotremex, S.flammeus (Siricidae); and Ophrynopus depressatus, O.plaumanni (Orussidae). Lopesiana is a new name for Lopesia Conde (Cimbicidae). Three new combinations and six new synonyms are proposed. The Xyelidae, Pamphiliidae, Diprionidae, Siricidae and Cephidae are primarily northern groups with southern extensions into Mexico, Central America and/or Cuba. The Cimbicidae, Xiphydriidae and Orussidae are more generally distributed throughout the neotropics. Keys to families, genera and species are provided.  相似文献

Reports of 129 new chromosome counts are made for the tribe Astereae of Compositae. They are mostly based on determinations of meiotic material, including first counts for one genus and 43 species or subspecies. Counts are now available for more than 63 of the 100-120 genera and 564 of the approximately 2,000 species in the tribe. Three of every four genera with more than one species counted show more than one chromosome number; 15 genera have species with populations with different numbers. Such variation is very high and indicates the need for more detailed cytotaxonomical study in the group.  相似文献

Squat lobsters (genus Munida and related genera) are among the most diverse taxa of western Pacific crustaceans, though several features of their biology and phylogenetic relationships are unknown. This paper reports an extensive phylogenetic analysis based on mitochondrial DNA sequences (cytochrome c oxidase subunit I and 16S rRNA) and the morphology of 72 species of 12 genera of western Pacific squat lobsters. Our phylogenetic reconstruction using molecular data supports the recent taxonomic splitting of the genus Munida into several genera. Excluding one species (M. callista), the monophyly of the genus Munida was supported by Bayesian analysis of the molecular data. Three moderately diverse genera (Onconida, Paramunida, and Raymunida) also appeared monophyletic, both according to morphological and molecular data, always with high support. However, other genera (Crosnierita and Agononida) seem to be para- or polyphyletic. Three new cryptic species were identified in the course of this study. It would appear that the evolution of this group was marked by rapid speciation and stasis, or certain constraints, in its morphological evolution.  相似文献

The psyllid-fauna of temperate and subantarctic South America comprises members of three families: Calophyidae, Triozidae and Psyllidae. Three subfamilies of the Psyllidae are revised in this paper: the Aphalarinae are represented by two species in two genera, one of which develops on Aquifoliaceae; the Rhinocolinae are represented by two congeneric species on Anacardiaceae while the Aphalaroidinae contain 38 species in seven genera trophically linked to the Compositae, Euphorbiaceae, Leguminosae, Myzodendraceae, Rhamnaceae, Solanaceae and Zygophyllaceae. The family Psyllidae (= Aphalaridae syn. nov. , =Spondyliaspididae syn. nov. ) and the constituent subfamily Aphalaroidinae (= Arepuninae syn nov. , = Ciriacreminae auct. pp) are redefined. Three genera and 30 species are described as new and two new generic, two new specific synonyms, and five new combinations are proposed. Information on larvae and host plant relationships is also given. Lectotypes are designated for eight species and a type-species is fixed for one genus. Keys are provided for the identification to species.  相似文献

The 36 species of the tribe Pronophilini known from the Cordillera de Merida, the main Andean mountain range in Venezuela, are listed, together with three others probably erroneously described or labelled as from the range. The general ecological characteristics of the tribe are described, using the Merida species as examples. These include its restriction to high altitudes, endemism in mountain 'islands', species partitioning up the altitude gradient, mimicry within the tribe, and seasonality. The evolutionary relationships of the 16 endemic species are analyzed. Two new genera, six new species, two new subspecies and one new form are described. Three new synonymies are established, three new combinations made, new status is given to two taxa and the status of one taxon is revised.  相似文献

Survey of the type of the Miocene Talpidae of Europe results in the allocation of several of the types to new or different genera. Three genera and one species previously referred to the family do not belong there. The diversity of Miocene talpids indicates an influx of generic stocks into Western Europe in the early Miocene, probably from Asia. New data provide a basis for a tentative phylogeny and classification of the European genera.  相似文献

Six new species of the Australian myrmecophilous ptinid genus Polyplocotes are described from South Australia. Three are from the deserts of central Australia, one from the Franklin Islands in the Great Australian Bight, one from Eyre Peninsula and one from the Riverland region. Morphologically, the majority of these new species are conventional Polyplocotes , but two are less typical. The characters uniting the genus are explored in the discussion, and comparisons are made to related genera. Although the six new species described here have not been observed in the field, the species of this genus are known to be myrmecophilous, and ant – beetle interactions similar to those seen in other spider beetles might occur between these new species and their host ants.  相似文献

Profound changes to the taxonomy and classification of polypores have occurred since the advent of molecular phylogenetics in the 1990s. The last major monograph of North American polypores was published by Gilbertson and Ryvarden in 1986–1987. In the intervening 30 years, new species, new combinations, and new records of polypores were reported from North America. As a result, an updated checklist of North American polypores is needed to reflect the polypore diversity in there. We recognize 492 species of polypores from 146 genera in North America. Of these, 232 species are unchanged from Gilbertson and Ryvarden’s monograph, and 175 species required name or authority changes. In addition, 40 new species and 45 new records published since that monograph are included in the checklist. Among the 492 species of polypores, 486 species from 143 genera belong to 11 orders, while six other species from three genera have uncertain taxonomic position at the order level. Three orders, viz. Polyporales, Hymenochaetales and Russulales, accommodate most of polypore species (93.7 %) and genera (88.8 %). We hope that this updated checklist will inspire future studies in the polypore mycota of North America and contribute to the diversity and systematics of polypores worldwide.  相似文献

Three genera and eight species, three new, of myxosporida were recovered from seven genera and twenty species of geographically dispersed macrourid fishes. The constancy in spore dimensions of these species over large distances and among many host species was remarkable. Two genera of myxosporida had species which dwelled in both the gall bladder and urinary bladder/kidney.  相似文献

Three new genera ( Araphura, Leptognathioides and Stenotanais ) and six new species of tanaid crustaceans from below 1000 m depth in the north-east Atlantic are described. Two of the new species belong to the genus Leptognathiella Hansen, 1913, which is redescribed and removed from synonymy with Leptognathia Sars, 1882 ( sensu Lang 1968). These species are relatively common in the tanaid material examined and have a widespread distribution in the area under study, i.e. the Rockall Trough, Porcupine Seabight and Bay of Biscay. All six species are found at depths between 2070 and 2892 m. A further nine species previously belonging to the genus Leptognathia are removed to the new genera or to Leptognathiella. New records of Leptognathioides polita (Hansen, 1913) comb.n. and Leptognathiella abyssi (Hansen, 1913) have been obtained.  相似文献

The classification of the Neotropical genera of the Ennominae is reviewed and 267 genera are recognised to occur in this region. Three new genera are described and three others are reinstated, while 48 generic synonyms are newly established. Other changes established in this work include 14 species synonyms and 237 new or reinstated combinations. External features and genitalia of representative members of the genera are illustrated (753 figures). All the known Neotropical species and subspecies of Ennominae are listed ( c . 3470), plus their synonyms. The tribes to which the genera belong are assessed, with c . 200 of the genera assigned to tribe or other suprageneric grouping.  © 2002 The Linnean Society of London, Zoological Journal of the Linnean Society , 2002, 135 , 121–401.  相似文献
