A review of the subgenus Carpelimus (s. str.) from tropical Africa is given. The subgenus includes 10 species. A new species C. uhligi sp. n. is described, neotype of Trogophloeus insularis, Kraatz 1858 is designated. T. aequithorax Bernhauer, 1932 is placed in synonymy with C. dieganus (Fauvel, 1904); T. oculatus Wollaston, 1865 and T. meridioafricanus Scheerpeltz, 1974, with C. insularis (Kraatz, 1858), T. rudebecki Scheerpeltz, 1974 with C. memnonius (Erichson, 1840); T. yemenicus Coiffait, 1981 with C. niloticus (Erichson, 1840); T. nigerrimus Coiffait, 1935 and T. mimus Cameron, 1945, with C. rufitarsis (Fauvel, 1907); and T. bredoi Bernhauer, 1943, with C. transmarinus (Fauvel, 1907). Lectotypes of T. aequithorax, T. calidus, T. nigerrimus, and T. bredoi are designated. Twenty species are transferred from the genus Carpelimus, and the following new combinations are formed: Thinodromus brincki Scheerpeltz, 1972; Th. montiumdraconis Scheerpeltz, 1974; Th. rhodesianus Scheerpeltz, 1974; and Th. sudanensis Scheerpeltz, 1974 comb. nn.). The initial generic placement of Carpelimus luzidus Cameron, 1944 is restored. 相似文献

Bees comprise a monophyletic group of seven families with more than 16000 described species worldwide. Convincing new phylogenetic hypotheses suggest that one of the smallest families, the Melittidae, could be the basal group of the bee clade. Among the 14 melittid genera, the genus Melitta Kirby 1802, is the most widespread and one of the most diverse. Most revisionary studies of Melitta were confined to limited geographical areas. An overview of the literature and the examination of 7817 specimens from various collections, including type material, have enabled the first monographic revision of the genus Melitta. This revision includes a cladistic analysis, comprehensive catalogue and identification key. We provide diagnoses, global distributions, phenology and host plants for the 43 known species (including 2 new ones). Lectotypes are designated for M. albofasciata Friese 1900, M. caroli Cameron 1909, M. schultzei Friese 1909 and M. sibirica (Morawitz 1888). We described M. rasmonti n. sp., M. guichardi n. sp., the previously unknown male of M. bicollaris Warncke 1973 and unknown female of M. murciana Warncke 1973. 相似文献

The tribe Rhynchosporeae comprises the genera Rhynchospora and Pleurostachys and has never been studied using molecular techniques. The objective of this study was to use an analysis of trnL-F sequences to evaluate the hypothesized taxonomic divisions within the Rhynchosporeae including the monophyly of the genera
and the soundness of the subgenera and sections. A total of 44 ingroup species were studied, 41 of Rhynchospora representing 22 of Kükenthal’s 28 sections, and three of Pleurostachys. Five outgroup species from other genera were also included. The cladistic analysis of 50 trnL intron and trnL-F intergenic spacer sequences resulted in 16 trees and a strict consensus tree. The Rhynchosporeae form two well-supported
primary clades with several well-supported smaller clades, many of which agree with previously hypothesized sections. Pleurostachys is embedded within the second primary clade. 相似文献

Philonthina, the largest subtribe of the rove beetle tribe Staphylinini, is a hyperdiverse group in the Neotropical Region, accounting for about half of the genera of the subtribe. Despite such diversity, Neotropical Philonthina have never been analysed phylogenetically, deterring formulation of a modern classification of the Staphylinini. A cladistic analysis of Neotropical Philonthina was performed based on 110 morphological characters and 77 terminal taxa. Representatives of Philonthina from other regions and other main lineages of Staphylinini, Arrowinini and Platyprosopini were included to test their relationships with Neotropical Philonthina. The major results are the monophyly of 11 of the 17 endemic Neotropical genera of Philonthina, the placement of Holisus Erichson (Hyptiomina) into this clade showing a sister group relationship to myrmecophile genera, and the position of Erichsonius Fauvel outside of Philonthina within Staphylinini. Six of the current seven species of Endeius Coiffait & Sáiz group with Neotropical species of Philonthus Stephens. The separation of Gondwana about 65 my and major landscape modifications in the vast interior of northern South America during the past 25 my is proposed to explain the evolution of the endemic Neotropical genera of Philonthina. The following taxonomic changes are proposed: Erichsonius Fauvel, 1874 now placed as incertae sedis in Staphylinini; Endeius Coiffait & Sáiz, 1968, n.syn. of Philonthus Stephens, 1929 and Endeius nitidipennis (Solier, 1849) placed as incertae sedis in Philonthina. The following new combinations are proposed: Philonthus franzi (Sáiz, 1971), comb.n. , Philonthus loensis (Coiffait & Sáiz, 1968), comb.n. , Philonthus lugubris (Sáiz, 1971), comb.n. , Philonthus ovaliceps (Coiffait, 1981), comb.n. , Philonthus punctipennis (Solier, 1849), comb.res. and Philonthus subpunctipennis (Coiffait & Sáiz, 1968), comb.n. Philonthus herberti, n.nov., is proposed for Philonthus franzi Schillhammer, 1998 , which is a junior secondary homonym of Philonthus franzi (Sáiz, 1971). 相似文献

The systematic position of the North American species of the genusGlyptotendipes is reviewed using morphological characters from all life history stages. The cladistic analysis revealed adult characters which support the monophyly of the three species groups (A, B and C) of PINDER and REISS (1983, 1986) for pupae and larvae. These species groups are given formal subgeneric status, with Group A becomingGlytotendipes, s.s., placingPhytotendipes Goetghebuer, 1937 in synonymy, Group B is namedCaulochironomus (type-species,Tendipes caulicola Kieffer, 1913) and Group C is namedTrichotendipes (type-species,Tendipes signatus Kieffer, 1911). 相似文献

Seven new calochroid and fulvoid species of Cortinarius 总被引:1,自引:0,他引:1
We describe seven new European species of Cortinarius. All species are based on analyses of morphological and DNA sequence data. They all belong to a well-supported clade comprising most species traditionally treated in Cortinarius subgenus Phlegmacium sections Fulvi and Calochroi (i.e. the/Calochroi clade). All taxa are either fulvoid (containing anthraquinoid pigments) or calochroid (without these pigments). Morphological and ecological data are presented for all species and compared with similar species. A dichotomous key is presented for C. calochrous and similar species, including all six newly described calochroid species. The calochroid species C. albertii, C. chailluzii, C. cisticola, C. sancti-felicis, C. selandicus and C. vesterholtii spp. nov., and the fulvoid species C. langeorum sp. nov. are described. 相似文献

A new aporocotylid blood fluke is described, based on specimens from the ventricle of the Pacific bluefin tuna, Thunnus orientalis (Temminck et Schlegel), cultured in Wakayama and Nagasaki Prefectures, Japan. The new species is morphologically similar to the members of the genus Cardicola Short, 1953, but shows distinct differences in the body form, location of the testis and the orientation of the ootype. The body of the new species is long and slender, whereas other Cardicola species are small and generally lanceolate. The testis is mostly located posterior to the caeca and anterior to the ovary, occupying 31–45% of body length, in contrast to the known Cardicola species, whose testis is typically intercaecal. The ootype is oriented anteriorly, while in most congeners, it is directed posteriorly or horizontally. Phylogenetic analyses of this aporocotylid, together with Cardicola orientalis Ogawa, Tanaka, Sugihara et Takami, 2010 from the same host, were conducted based on DNA sequences of the ITS2 rDNA and the 28S region of ribosomal RNA. The analyses revealed that the new blood fluke belongs to the genus Cardicola despite the marked morphological differences. Thus, this aporocotylid is named Cardicola opisthorchis n. sp. and the generic diagnosis is emended in this paper. In addition, 100% identity among the ITS2 sequences from the present species, Cardicola sp. from T. orientalis in Mexico and Cardicola sp. from the northern bluefin tuna, Thunnus thynnus (Linnaeus) in Spain suggests that C. opisthorchis n. sp. has a broad geographical distribution and that it infects both the Pacific and northern bluefin tuna. 相似文献

Kinorhyncha from the stomach of the shrimp Pleoticus muelleri (Bate, 1888) from Comodoro Rivadavia, Argentina 总被引:1,自引:0,他引:1
Six kinorhynchs were found in the stomachs of the Argentine red shrimp, Pleoticus mulleri (Bate, 1888) from the Argentine coast of Patagonia. Three new species are described: Condyloderes storchi n. sp., Pycnophyes argentinensis n. sp. and P. neuhausi n. sp. A fourth species, Kinorhynchus anomalus Lang, 1953 was previously known only from the coast of Chile. This is the third known record of kinorhynchs documented as a food source. Condyloderes storchi, n. sp. is the fourth new species in this genus. It is distinguished by its paradorsal cuspidate spines on segments 7 and 9, lateral accessory and ventrolateral spines on segments 3, 6, 7, 10 and 11. P. argentinensis, n. sp. has nearly equal sternal width for segments 3–11 (about 7% of the trunk length), episternal plates with three distinct areas along the anterior margin, mid-sternal plate with even margin, mid-dorsal spinose protrusions along the terminal borders of segments 11 and 12, and lateral terminal spines 176 μm long, about 21% of trunk length. P. neuhausi, n. sp.has a prominent posterior elongation of the tergal plate of segment 3, uneven lateral margins of the mid-sternal plate, a maximum sternal width at segment 3, no mid-dorsal spinose processes and mid-ventral thickenings on segments 10–12. 相似文献

A review of aphidiine wasps (Hymenoptera: Braconidae) parasitizing the Uroleucon species in the West Palaearctic is presented. Eleven species are keyed and illustrated. In addition, a new hymenopteran parasitoid species: Praon nonveilleri n. sp. from Uroleucon inulicola (Hille Ris Lambers) infesting Inula ensifolia L., is described. The new species is diagnosed and illustrated. It belongs to the “dorsale-yomenaé” species group and was collected from the Djetinja canyon in Serbia and Montenegro. The aphidiines presented in this work were identified from 97 aphid taxons occurring on 236 plant taxons. Furthermore, 361 original parasitoid – host aphid – host plant associations of the species mentioned in the key are presented. Finally, phylogenetic relationships inside the “dorsale-yomenae” species group and related species were reconstructed using cladistic distance methods. 相似文献

Based on extensive phenetic analyses, bats of the genus Myotis have been classically subdivided into four major subgenera each of which comprise many species with similar morphological and ecological adaptations. Each subgenus thus corresponds to a distinct “ecomorph” encompassing bat species exploiting their environment in a similar fashion. As three of these subgenera are cosmopolitan, regional species assemblages of Myotis usually include sympatric representatives of each ecomorph. If species within these ecomorphs are monophyletic, such assemblages would suggest extensive secondary dispersal across geographic areas. Conversely, these ecomorphological adaptations may have evolved independently through deterministic processes, such as adaptive radiation. In this case, phylogenetic reconstructions are not expected to sort species of the same ecomorph into monophyletic clades. To test these predictions, we reconstructed the phylogenetic history of 13 American, 11 Palaearctic, and 6 other Myotis species, using sequence data obtained from nearly 2 kb of mitochondrial genes (cytochrome b and nd1). Separate or combined analyses of these sequences clearly demonstrate the existence of several pairs of morphologically very similar species (i.e., sibling species) which are phylogenetically not closely related. None of the three tested subgenera constitute monophyletic units. For instance, Nearctic and Neotropical species currently classified into the three subgenera were clustered in a single, well-supported monophyletic clade. These species thus evolved independently of their ecological equivalents from the Palaearctic region. Independent adaptive radiations among species of the genus Myotis therefore produced strikingly similar evolutionary solutions in different parts of the world. Furthermore, all phylogenetic reconstructions based on mtDNA strongly supported the existence of an unsuspected monophyletic clade which included all assayed New World species plus M. brandtii (from the Palaearctic Region). This “American” clade thus radiated into a morphologically diverse species assemblage which evolved after the first Myotis species colonized the Americas. Molecular reconstructions support paleontological evidence that species of the genus Myotis had a burst of diversification during the late Miocene–early Pliocene epoch. 相似文献

Lygodium microphyllum, first naturalized in the 1960s, has aggressively invaded forest-dominated wetlands in southern and central Florida. The indeterminate growth of this invasive climbing fern creates thick rachis mats which climb over shrubs and trees smothering the underlying growth and carrying ground fires into the forest canopy. Foreign surveys for natural enemies identified 20 species of insects and two species of mites. Host range testing of three insect species and one mite included five Lygodium species (L. palmatum, L. volubile, L. cubense, L. venustum, and L. oligostachyum) native to the United States and the West Indies. A molecular phylogeny of the genus was conducted using the trnL intron and the trnL-F intergenic spacer of chloroplast DNA to determine the relationship of L. microphyllum to other Lygodium species. Three major clades appeared, one with L. palmatum and L. articulatum (the most basal), a second with L. reticulatum and L. microphyllum, and a third comprising the other species examined. Lygodium microphyllum appeared at the end of a long branch approximately equidistant from all species of interest preventing the correlation of genetic distance and host range behavior. However, inspection of the results of host range experiments showed a relationship between the presence of a related biotype or species of the insect on a related alternate host and the ability of that insect to develop on that alternate host. Ancestral host usage and ecological fitting are examined as possible explanations for the acceptance of L. palmatum by the tested musotimine insects. 相似文献

Bactrocera latifrons (Hendel) (Diptera: Tephritidae) is the most recent of four tephritid fruit fly species accidentally introduced into Hawaii. Although parasitoids have been released against other tephritid fruit fly species and have shown partial success in Hawaii, no parasitoids were released until 2004 to suppress populations of B. latifrons. The present study was conducted to document the parasitoid complex that has naturally established against B. latifrons in Hawaii and to assess whether there is a need for improving the biological control of this species. Based on ripe turkeyberry (Solanum torvum Sw) fruit collections over three consecutive years B. latifrons was the dominant tephritid fruit fly infestating turkeyberry at all four sites surveyed, across three major islands in Hawaii. The overall percentage parasitism of B. latifrons ranged from a low of 0.8% (Hana, Maui) to a high of 8.8% (Kahaluu, Oahu). Five primary parasitoid species were recovered from individually held B. latifrons puparia: Fopius arisanus (Sonan), Psyttalia incisi (Silvestri), Diachasmimorpha longicaudata (Ashmead), D. tryoni (Cameron), and Tetrastichus giffardianus Silvestri. F. arisanus was the predominant parasitoid at three of the four sites. Low levels of parasitism suggest that there is a need to improve biological control of B. latifrons, to minimize chances of this species causing economic impacts on crop production in Hawaii. We discuss the possibility of improving biological control of B. latifrons through augmentative releases of F. arisanus or introduction and release of specific and efficient new parasitoid species. 相似文献

Four species of Sunaristes (Canuellidae) are known to live in association with hermit crabs and exhibit a degree of host specificity. Although hermit crabs are common in many parts of the world, Sunaristes is notably absent from waters of the New World. The phylogeny of Sunaristes is here examined through a cladistic analysis. The reconstructed phologeny indicates that S. inaequalis and S. japonicus form a sister group, and its closest relative is S. tranteri. The sister taxon of this 3-species clade is S. paquri. It is assumed that Sunaristes evolved in the Paleocene on the north shore of the Tethys seaway. The constructed cladogram forms the basis for the analysis of vicariant events that led to the speciation and development of the present pattern of distribution of Sunaristes. 相似文献

圆叶玉兰叶片非结构性碳水化合物与氮、磷含量对海拔的响应 总被引:1,自引:0,他引:1
非结构性碳水化合物(non-structural carbohydrates, NSC)、氮(N)和磷(P)是植物生长的重要能源物质和影响植物分布的限制生长因子,圆叶玉兰(Magnolia sinensis)是四川省特有的珍稀濒危极小种群野生植物,研究其NSC、N和P可以反映它的营养供应水平及对环境的适应策略。选取芦山6个海拔梯度(1840,1960,2070,2170,2270,2390 m)的圆叶玉兰为对象,研究不同海拔下圆叶玉兰叶片中NSC与N、P及其化学计量间的关系。结果表明,圆叶玉兰叶片可溶性糖含量在2390 m处显著高于1840 m处, NSC含量在不同海拔差异极显著,随海拔增加呈"低-高-低"的单峰变化,2170 m处叶片NSC含量最高,碳水化合物供应充足;可溶性糖/淀粉的比值随海拔升高呈增大趋势,N含量和N/P比都随海拔上升而下降,且N/P比在各海拔上均小于14,NSC/N比在2390 m处显著高于1840 m处。总之,圆叶玉兰叶片的可溶性糖和NSC含量显著不受海拔的影响,较高的可溶性糖含量有利于抵御低温环境,其生长主要受氮元素限制而不受碳限制,反映了濒危植物圆叶玉兰在其有限的分布范围内NSC及N、P的保护策略,为圆叶玉兰的碳代谢和生长适应对策提供数据基础。 相似文献

Three species of Rhabdolaimus de Man, 1880 and two (of which one is new to science) of Udonchus Cobb, 1913 are described from sediment samples of two lakes, two rivers and a hot spring, Ethiopia. Udonchus merhatibebi n.sp. is characterized by a distinctly truncate lip region and small cardia surrounded by gland cells that he on the anterior intestine at 45 °. The presence of twelve rugae in the cheilostome in the genus Udonchus is reported here for the first time. As a result, the family Rhabdolaimidae has been moved from suborder Leptolaimina to the superfamily Microlaimoidea in the suborder Chromadorina. The family Rhabdolaimidae is also subdivided into the subfamilies Rhabdolaiminae Chitwood, 1951 and Undonchinae n. subfam.. Scanning electronmicroscopic pictures of the five species viz. R. aquaticus de Man, 1880, R. cf. minor Cobb, 1914, R. terrestris de Man, 1880, U. merhatibebi n.sp. and U. tenuicaudatus Cobb, 1913 are also given.Abbreviations ABE =
