In this paper, twelve insidiosus-group species of the genus Metaphycus Mercet from China are reviewed. Five species, M. corniae sp. n., M. cylindricus sp. n., M. deltoideus sp. n., M. transversus sp. n. and M. yaanensis sp. n., are described as new to science. A key to the females of these species is given to facilitate species recognition. Photomicrographs are provided to illustrate morphological characters of these species. All specimens, unless otherwise specified, are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing.  相似文献

Myriophyllum quitense andM. ussuriense are added to the flora of British Columbia, Canada.Myriophyllum quitense has not been previously reported in Canada, and this is the first report ofM. ussuriense for the North American continent. Problems with the identification of these species, and their distributions and habitats are discussed. The somatic chromosome numbers of 2n=42 forM. quitense and 2n=21 forM. ussuriense were found. A key for the identification ofMyriophyllum taxa growing in British Columbia is given.  相似文献

Proteins and various isozymes were investigated by direct analysis of single specimens in order to check molecular genetic variability, which is not rare in Meloidogyne species in spite of parthenogenetic reproduction. Variability was found in esterases, ocglycerophosphate, malate dehydrogenases, and some other proteins. Other loci appear monomorphic in the genus (for example, catalase), Distinct pools of genes are in a relative accordance with the common described species. Characteristic electrophoretograms are given for M. arenaria, M. javanica, M. incognita, M. hapla, and M. naasi, and it appears that nonspecific esterases are a useful tool supplementing morphology for specific characterization. Because the biochemical evidence is less subjective than the morphological, we believe it is more reliable.  相似文献

A taxonomic revision of Australian Macrobrachium identified three species new to the Australian fauna – two undescribed species and one new record, viz. M. auratumsp. nov., M. koombooloombasp. nov., and M. mammillodactylus(Thallwitz, 1892). Eight taxa previously described by Riek (1951) are recognised as new junior subjective synonyms, viz. M. adscitum adscitum, M. atactum atactum, M. atactum ischnomorphum, M. atactum sobrinum, M. australiense crassum, M. australiense cristatum, M. australiense eupharum of M. australienseHolthuis, 1950, and M. glypticumof M. handschiniRoux, 1933. Apart from an erroneous type locality for a junior subjective synonym, there were no records to confirm the presence of M. australe(Guérin-Méneville, 1838) on the Australian continent. In total, 13 species of Macrobrachiumare recorded from the Australian continent. Keys to male developmental stages and Australian species are provided. A revised diagnosis is given for the genus. A list of 31 atypical species which do not appear to be based on fully developed males or which require re-evaluation of their generic status is provided. Terminology applied to spines and setae is revised.  相似文献

A total of 15 species of Manota Williston, 1896 are recorded from Brunei, based on the investigations in 2013-2014. Thirteen species are recorded from Ulu Temburong National Park and three species from the Universiti Brunei Darussalam Campus in Tungku. Six species are described as new to science: Manota belalongensis sp. n., M. kaspraki sp. n., M. macrothrix sp. n., M. megachaeta sp. n. and M. pileata sp. n. from Ulu Temburong, and M. ricina sp. n. from Tungku. New records of the following species are given: Manota bifida Hippa & Papp, M. bruneiensis Hippa & Ševčík, M. hyboloma Hippa & Ševčík, M. oligochaeta Hippa, M. pappi Hippa, M. perangulata Hippa & Ševčík, M. pollex Hippa, M. procera Hippa and M. simplex Hippa.  相似文献

Chromolaena ternicapitulata is described from Sierra de Maigualida in T. F. Amazonas and a key to the species of Chromolaena from Guayana is given. Newly documented for the flora of Venezuela are M. aschersonii Hieron. and M. amazonica Baker, the second herein resurrected from the synonymy of common and widespread M. sprucei Baker. Mikania karsteniana Klot. ex Hieron. is not considered synonymous with M. pannosa Baker, thus the latter is again considered to be endemic to Guayana.  相似文献

Microsiphum Cholodkovsky (Macrosiphini) is a small genus comprising 11 species and subspecies distributed in the Palaearctic Region. After examination of the collection of the Institute of Zoology (Kazakhstan), Microsiphum diversisetosum sp. n. from Artemisia abrotanum (northern and western Kazakhstan) is described. New synonymies are established: M. nudum Holman, 1961 = M. minus Bozhko, 1963, syn. n., M. ptarmicae Cholodkovsky, 1902 = M. heptapotamicum Kadyrbekov, 2000, syn. n. The taxonomic rank of M. procerae subalpicum Mamontova, 1982 stat. n. and M. jazykovi wahlgreni Hille Ris Lambers, 1947 stat. n. is changed. A key to the known taxa of the genus Microsiphum is given.  相似文献

Phylogenies were inferred from nearly complete small subunit (SSU) 18S rDNA sequences of 12 species of Meloidogyne and 4 outgroup taxa (Globodera pallida, Nacobbus abberans, Subanguina radicicola, and Zygotylenchus guevarai). Alignments were generated manually from a secondary structure model, and computationally using ClustalX and Treealign. Trees were constructed using distance, parsimony, and likelihood algorithms in PAUP* 4.0b4a. Obtained tree topologies were stable across algorithms and alignments, supporting 3 clades: clade I = [M. incognita (M. javanica, M. arenaria)]; clade II = M. duytsi and M. maritima in an unresolved trichotomy with (M. hapla, M. microtyla); and clade III = (M. exigua (M. graminicola, M. chitwoodi)). Monophyly of [(clade I, clade II) clade III] was given maximal bootstrap support (mbs). M. artiellia was always a sister taxon to this joint clade, while M. ichinohei was consistently placed with mbs as a basal taxon within the genus. Affinities with the outgroup taxa remain unclear, although G. pallida and S. radicicola were never placed as closest relatives of Meloidogyne. Our results show that SSU sequence data are useful in addressing deeper phylogeny within Meloidogyne, and that both M. ichinohei and M. artiellia are credible outgroups for phylogenetic analysis of speciations among the major species.  相似文献

Three new species of the genus Mycterodus Spinola are described: M. phoenicicus sp. n. from Lebanon and M. syriacus sp. n. from Syria, both belong to the subgenus Aegaeum Gnezdilov, and M. marki sp. n. from Turkey, belongs to the subgenus Aconosimus Dlabola. Figures of the described species and of the holotype of M. anaticeps Puton are given. M. efesicus Dlabola is for the first time recorded from Greece (Samos I.); M. alatus Logvinenko, M. caucasicus (Melichar), and M. johannesi Gnezdilov &; Drosopoulos are new to the fauna of Turkey.  相似文献
