Two novel yeast species, Asterotremella meifongana sp. nov. and Asterotremella nantouana sp. nov., belonging to Asterotremellaceae within the Trichosporonales, are proposed to accommodate five strains isolated from Taiwanese samples of soil and basidiocarps during 2006-2007. Sequence analysis of the D1/D2 domains of the large subunit rRNA gene revealed that the two species are phylogenetically closely related to species of the genus Asterotremella, which indicates that they are members of the genus. The two species can be further differentiated from other Asterotremella species based on their internal transcribed spacer sequences, as well as on a few physiological test responses. The type strains are A. meifongana SN4S04(T) (=CBS 11424(T) = BCRC 23196(T)) and A. nantouana SN5S06(T) (=CBS 10890(T) = BCRC 23135(T)).  相似文献

Trisopterus is demonstrated to be monophyletic, including four distinct species: T. capelanus, T. esmarkii, T. luscus and T. minutus. The capelan T. capelanus is resurrected from the synonymy of poor cod T. minutus, and is shown to be morphologically more similar to T. luscus, to which species it is also more closely related, indicated by a phylogenetic analysis presented here. A lectotype is designated for T. luscus. Trisopterus fasciatus, the type species of Trisopterus, is a junior synonym of T. luscus, and the lectotype of T. luscus is designated as the neotype of T. fasciatus. The lectotype of T. luscus is also designated as the neotype of Gadus barbatus. Gadus barbatus has priority over T. luscus but the name is suppressed by prevailing usage of T. luscus. A neotype is designated also for T. minutus. A phylogenetic analysis using mitochondrial cytochrome b, and a fragment of the nuclear rhodopsin gene, shows that T. capelanus and T. luscus are sister species, and in turn sister to a clade formed by T. minutus and T. esmarkii.  相似文献

A morphological and taxonomic account of the genus Trigonostomum is provided. All known species are discussed and briefly re-described where necessary. Seven new species are described: T. franki from Curaçao, Florida (USA), the East African Coast and New Caledonia, T. nataschae from the French sub-Antarctic island Kerguelen, T. spinigerum from New Caledonia and T. watsoni from the Australian East Coast and New Caledonia. T. tori and T. galapagoensis , both formerly enclosed in T. setigerum , are considered new species, while T. australis also belongs to the same species group. Proxenetes denhartogi is transferred to Trigonostomum . Based on a comparison of old and new material, T. marki is synonymized with T. penicillatum , while T. prytherchi and T. divae are regarded as junior synonyms of T. lilliei ; T. intermedium and T. quadrifolium are considered synonyms of T. coronatum . Three species are considered species inquirendae : T. brunchorsti , T. piriforme and Marinellia lingulifera . Similarities and differences of the 17 valid species are discussed and summarized in an identification key.  © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society , 2004, 141 , 271–296.  相似文献

This paper re-examines the species of Triplophyllum in the neotropics. The indument of the laminae (hairs and glands) provides many characteristics for distinguishing the species. Nine species are recognized, including three new ones: T. boliviense, T. chocoense, and T. glabrum. New combinations are made for T. hirsutum and T. perpilosum . A key is provided to distinguish the species, and all species are described and illustrated. The spores of the neotropical species are like those from African and Madagascan species. As such, they offer no evidence to determine whether the neotropical species form a monophyletic clade within the genus.  相似文献

A new species of white truffles, Tuber latisporum, is described from southwestern China. This species can be distinguished from other species in the genus by its white and pubescent ascomata, pseudoparenchymatous peridium and broadly ellipsoid ascospores with alveolate reticulum. Molecular phylogenetic analyses of this and morphologically similar species using ITS sequences demonstrated that it is significantly different from other white truffles such as T. borchii, T. puberulum, T. zhongdianense, T. liui, T. dryophilum, T. magnatum, T. rapaeodorum, T. foetidum and T. maculatum. Data from ITS sequences indicate that white and black truffles are not monophyletic lineages.  相似文献

Bitterling are fishes that use freshwater mussels for oviposition. The reproductive ecology and pattern of mussel utilization of four sympatric species of bitterling, Acheilognathus rhombeus, A. tabira tabira, Tanakia lanceolata, and T. limbata, were investigated in a lowland river with seven sympatric mussel species. Three bitterling species are spring spawners with overlapping spawning seasons. A. rhombeus is an autumn-spawning species and is temporally isolated in its reproduction from the other species. Ovipositor length during oviposition of T. limbata and T. lanceolata was short, while those of A. tabira tabira and A. rhombeus were long. Most T. limbata inhabited near-shore areas, whereas the two other spring-spawning species were distributed across the entire river. All bitterling species used Inversidens brandti, Obovalis omiensis and Inversiunio jokohamensis as spawning hosts, but not the other mussel species available. T. lanceolata, A. tabira tabira and A. rhombeus showed spawning preferences for O. omiensis and I. brandti. However, T. limbata did not show clear preferences for any of the mussel species they used. A. t. tabira showed a significant preference for large I. brandti in offshore areas, while the other spring-spawning bitterling showed a preference for mussels inshore. These results are discussed in the context of reproductive resource partitioning.  相似文献

A new species of Trichoderma (teleomorph Hypocrea, Ascomycota, Sordariomycetes, Hypocreales, Hypocreaceae), T. amazonicum, endophytic on the living sapwood and leaves of Hevea spp. trees is described. Trichoderma amazonicum is distinguished from closely related species in the Harzianum clade (e.g. Hypocrea alni, H. brunneoviridis, H. epimyces, H. parepimyces, T. aggressivum, T. harzianum, T. pleuroticola and T. pleuroti) by morphological and ecological characteristics and phylogenetic analysis of three loci (ITS nrDNA, tef1 and rpb2). The closest relatives of this species are the facultatively fungicolous species T. pleuroticola and T. pleuroti.  相似文献

A review of the North American species of the genus Tarphiota Casey is presented. Three species are recognized: T. densa (Moore), T. fucicola (Mäklin), and T. geniculata (Mäklin). They occur on the sandy beaches of the Pacific coast. A new coastal species of Atheta, found on the seashore and exhibiting certain convergent characteristics to Tarphiota, is described from the Atlantic coast: A. novaescotiae Klimaszewski and Majka, sp. nov. All Canadian species are provided with diagnoses, genitalic illustrations and digital photos of their habitus in dorsal and lateral view. A key is presented to distinguish the species. New data on the natural history of A. novaescotiae are presented and briefly discussed.  相似文献

Abstract  A thrips associated in Thailand with the flowers of Paederia foetida , a rubiaceous weed in Florida that is a threat to Australia, is here recognised as Thrips morindae Priesner, a species previously considered a synonym of T. javanicus Priesner. Systematic relationships of these species with others in South-east Asia and the Australasian region are discussed. Two new species-groups are designated: the T. obscuratus group of six species from New Zealand and New Caledonia, and the T. orientalis group of 12 South-east Asian species that are associated with scented white flowers such as Gardenia . Four species of this second group are recorded from tropical Australia.  相似文献
