Anaporrhutine gorgoderids (Digenea: Gorgoderidae: Anaporrhutinae) found in the body cavity of six species of elasmobranchs from the orders Carcharhiniformes, Myliobatiformes and Orectolobiformes from Australian waters were found to belong to the genus Staphylorchis. Although these specimens were morphologically variable, sequences of ITS2 and 28S ribosomal DNA from specimens from three host families and two host orders were identical. Based on morphological and molecular data these specimens were identified as the type-species of the genus, Staphylorchis cymatodes. New measurements are provided for S. cymatodes, and for the first time genetic data are presented for this species. In addition to providing new morphological and molecular data for S. cymatodes, the previously described species S. gigas, S. parisi and S. scoliodonii, are here synonymised with S. cymatodes. This implies that S. cymatodes, as conceived here, has remarkably low host-specificity, being recorded from eight elasmobranch species from four families and three orders, has a wide geographical distribution in the Indo-west Pacific from off India, in the Bay of Bengal, to Moreton Bay in the Coral Sea, and is morphologically plastic, with body size, size of specific organs and body shape differing dramatically between specimens from different host species. The genus Staphylorchis now contains only two valid species, S. cymatodes and S. pacifica. 相似文献

The Neotropical genus Catharylla Zeller, 1863 (type species: Crambus tenellus Zeller, 1839) is redescribed. Catharylla contiguella Zeller, 1872, C. interrupta Zeller, 1866 and Myelois sericina Zeller, 1881, included by Munroe (1995) in Catharylla, are moved to Argyria Hübner. Catharylla paulella Schaus, 1922 and C. tenellus (Zeller, 1839) are redescribed. Six new species are described by Léger and Landry: C. bijuga, C. chelicerata, C. coronata, C. gigantea, C. mayrabonillae and C. serrabonita. The phylogenetic relationships were investigated using morphological as well as molecular data (COI, wingless, EF-1α genes). The median and subterminal transverse lines of the forewing as well as the short anterior and posterior apophyses of the female genitalia are characteristic of the genus. The monophyly of Catharylla was recovered in all phylogenetic analyses of the molecular and the combined datasets, with three morphological apomorphies highlighted. Phylogenetic analyses of the morphology of the two sexes recovered three separate species groups within Catharylla: the chelicerata, the mayrabonillae, and the tenellus species groups. The possible position of Micrelephas Schaus, 1922 as sister to Catharylla, based on both morphological and molecular data, and the status of tribe Argyriini are discussed. The biogeographical data indicate that the chelicerata species group is restricted to the Guyanas and the Amazonian regions whereas the tenellus group is restricted to the Atlantic Forest in the South-Eastern part of Brazil. The mayrabonillae group is widespread from Costa Rica to South Bolivia with an allopatric distribution of the two species. COI barcode sequences indicate relatively strong divergence within C. bijuga, C. mayrabonillae, C. serrabonita and C. tenellus. 相似文献

This paper presents the first complete and updated list of all 3597 species of beetles (Insecta: Coleoptera) belonging to 92 familiesfound and published in Lithuania until 2011, with comments also provided on the main systematic and nomenclatural changes since the last monographic treatment in two volumes (Pileckis and Monsevičius 1995, 1997). The introductory section provides a general overview of the main features of the territory of Lithuania, the origins and formation of the beetle fauna and their conservation, the faunistic investigations in Lithuania to date revealing the most important stages of the faunistic research process with reference to the most prominent scientists, an overview of their work, and their contribution to Lithuanian coleopteran faunal research.Species recorded in Lithuania by some authors without reliable evidence and requiring further confirmation with new data are presented in a separate list, consisting of 183 species. For the first time, analysis of errors in works of Lithuanian authors concerning data on coleopteran fauna has been conducted and these errors have been corrected. All available published and Internet sources on beetles found in Lithuania have been considered in the current study. Over 630 literature sources on species composition of beetles, their distribution in Lithuania and neighbouring countries, and taxonomic revisions and changes are reviewed and cited. An alphabetical list of these literature sources is presented. After revision of public beetle collections in Lithuania, the authors propose to remove 43 species from the beetle species list of the country on the grounds, that they have been wrongly identified or published by mistake. For reasons of clarity, 19 previously noted but later excluded species are included in the current checklist with comments. Based on faunal data from neighbouring countries, species expected to occur in Lithuania are matnioned. In total 1390 species are attributed to this category and data on their distribution in neighbouring countries is presented. Completion of this study provides evidence that the Lithuanian coleopteran fauna has yet to be completely investigated and it is estimated that approximately 28 % of beetle species remain undiscovered in Lithuania. More than 85% of beetle species expected for Lithuania have been found in the following families: Cerylonidae, Geotrupidae, Haliplidae, Kateridae, Lycidae, Lucanidae, Mycetophagidae, Scarabaeidae and Silphidae. In families with few species such as Alexiidae, Boridae, Byturidae, Dascilidae, Drilidae, Eucinetidae, Lampyridae, Lymexilidae, Megalopodidae, Nemonychidae, Nosodendridae, Noteridae, Orsodacnidae, Pyrochroidae, Pythidae, Psephenidae, Rhysodidae, Sphaeritidae, Sphaeriusidae, Sphindidae, Stenotrahelidae and Trogidae, all possible species have already been discovered. However in some beetle families such as Aderidae, Bothrideridae, Eucnemidae, Laemoploeidae, Mordellidae, Ptiliidae, Scraptidae and Throscidae less than 50% of all possible species are known. At present the beetle species recorded in Lithuania belong to 92 families, with species from 9 other families such as Agyrtidae, Biphylidae, Deradontidae, Mycteridae, Ochodaeidae, Phleophilidae, Phloeostichidae, Prostomidae, Trachypachidae are expected to be found.A bibliography and a index of subfamily and genus levels are provided. The information published in the monograph will serve to further faunistic and distribution research of beetles and will help to avoid confusion in the identificatation of coleopteran fauna of Lithuania. 相似文献

Ten unusual decapod crustacean species are reported for the coasts of Galicia (NW Spain), eight of them recorded for the first time in this area. Three species: Pilumnopeus africanus, Charybdis hellerii and Pachygrapsus gracilis, are non-indigenous species. The reports of Panopeus africanus and Inachus aguiarii represent the northernmost localities of these African species, whose previous North limits were in the Southwestern European coasts. Remaining five species: Xaiva biguttata, Bathynectes longipes, Parthenopoides massena, Monodaeus couchii and Homola barbata are scarcely known species found within their distribution range. Updated data about these species are given, both from the point of view of their distribution and identification (morphological and molecular methods), as well as the potential pathways for introduction of the non-indigenous ones. According to evidence presented in the present study, biofouling still remains an important vector of species transmission and surely has been undervalued with respect to ballast water. 相似文献

Understanding the systematics and evolution of clavicipitoid fungi has been greatly aided by the application of molecular phylogenetics. They are now classified in three families, largely driven by reevaluation of the morphologically and ecologically diverse genus Cordyceps. Although reevaluation of morphological features of both sexual and asexual states were often found to reflect the structure of phylogenies based on molecular data, many species remain of uncertain placement due to a lack of reliable data or conflicting morphological characters. A rigid, darkly pigmented stipe and the production of a Hirsutella-like anamorph in culture were taken as evidence for the transfer of the species Cordyceps cuboidea, Cordyceps prolifica, and Cordyceps ryogamiensis to the genus Ophiocordyceps. Data from ribosomal DNA supported these species as a single group, but were unable to infer deeper relationships in Hypocreales. Here, molecular data for ribosomal and protein coding DNA from specimens of Ophiocordyceps cuboidea, Ophiocordyceps ryogamiensis, Ophiocordyceps paracuboidea, Ophiocordyceps prolifica, Cordyceps ramosopulvinata, Cordyceps nipponica, and isolates of Polycephalomyces were combined with a broadly sampled dataset of Hypocreales. Phylogenetic analyses of these data revealed that these species represent a clade distinct from the other clavicipitoid genera. Applying the recently adopted single system of nomenclature, new taxonomic combinations are proposed for these species in the genus Polycephalomyces, which has been historically reserved for asexual or anamorphic taxa. 相似文献

Currently choanoflagellates are classified into two distinct orders: loricate Acanthoecida and non-loricate Craspedida. The morphologically based taxonomy of the order Craspedida is in need of a revision due to its controversial, paraphyletic and inconsistent systematics and nomenclature. In this study, we add molecular data (SSU and parts of the LSU rDNA) of six new Craspedida species isolated from saline, brackish and freshwater habitats to the existing knowledge. Four of these six organisms could be described as new species: Paramonosiga thecata, “Salpingoeca” euryoecia, “Salpingoeca” ventriosa, “Sphaeroeca” leprechaunica, whereas two are assigned to previous morphologically described species: “Salpingoeca” fusiformis Saville Kent, 1880 and “Salpingoeca” longipes Saville Kent, 1880. Paramonosiga is established as a new genus of the Craspedida based on its phylogenetic position. Extending the dataset by six additional sequences shows that the craspedid taxonomy is still unsolved as the type specimen Salpingoeca gracilis has not yet been sequenced and hence a clear assignment to the genus Salpingoeca is not possible. Trying to assign morphological and ecological data to phylogenetic clades is not successful. We give an improved/emended morphological diagnosis for the two redescribed species and add molecular data for all six species, shedding light on their phylogenetic position. 相似文献

Mitogenomic analysis of decapod crustacean phylogeny corroborates traditional views on their relationships 总被引:1,自引:0,他引:1
Phylogenetic relationships within decapod crustaceans are highly controversial. Even recent analyses based on molecular datasets have shown largely contradictory results. Previous studies using mitochondrial genomes are promising but suffer from a poor and unbalanced taxon sampling. To fill these gaps we sequenced the (nearly) complete mitochondrial genomes of 13 decapod species: Stenopus hispidus, Polycheles typhlops, Panulirus versicolor, Scyllarides latus, Enoplometopus occidentalis, Homarus gammarus, Procambarus fallax f. virginalis, Upogebia major, Neaxius acanthus, Calocaris macandreae, Corallianassa coutierei, Cryptolithodes sitchensis, Neopetrolisthes maculatus, and add that of Dromia personata. Our new data allow for comprehensive analyses of decapod phylogeny using the mitochondrial genomes of 50 species covering all major taxa of the Decapoda. Five species of Stomatopoda and one species of Euphausiacea serve as outgroups. Most of our analyses using Maximum Likelihood (ML) and Bayesian inference (BI) of nucleotide and amino acid datasets revealed congruent topologies for higher level decapod relationships: (((((((Anomala, Brachyura), Thalassinida: Gebiidea), Thalassinida: Axiidea), (Astacidea, Polychelida), Achelata), Stenopodidea), Caridea), Dendrobranchiata). This result corroborates several traditional morphological views and adds new perspectives. In particular, the position of Polychelida is surprising. Nevertheless, some problems can be identified. In a minority of analyses the basal branching of Reptantia is not fully resolved, Thalassinida are monophyletic; Polychelida are the sister group to Achelata, and Stenopodidea are resolved as sister group to Caridea. Despite this and although some nodal supports are low in our phylogenetic trees, we think that the largely stable topology of the trees regardless of different types of analyses suggests that mitochondrial genomes show good potential to resolve the relationship within Decapoda. 相似文献

This paper applies multivariate statistical methods to a data set of weed relevés from arable fields in two different habitat types of coastal and mountainous escarpments in Southern Oman. The objectives were to test the effect of environmental gradients, crop plants and time on weed species composition, to rank the importance of these particular factors, and to describe the patterns of species composition and diversity associated with these factors. Through the application of TWINSPAN, DCA and CCA programs on data relating to 102 species recorded in 28 plots and farms distributed in the study area, six plant communities were identified: I- Dichanthium micranthum, II- Cynodon dactylon–D. micranthum, III- Convolvulus arvensis, IV- C. dactylon–Sonchus oleraceus, V- Amaranthus viridis and VI- Suaeda aegyptiaca–Achyranthes aspera. The ordination process (CCA) provided a sequence of plant communities and species diversity that correlated with some anthropogenic factors, physiographic variables and crop types. Therefore, length of time since farm construction, disturbance levels and altitude are the most important factors related to the occurrence of the species. The perennial species correlated with the more degraded mountain areas of new farm stands, whereas most of the annuals correlated with old lowland and less disturbed farms. 相似文献

Seed, kernel or fruit oils of the Cornaceae (nine species). Hydrangea, Hamamelis, Ilex (Aquifoliaceae) and the Styracaceae (two species) were analysed for fatty acid composition. Special attention was paid to the occurrence of petroselinic acid (18: 1Δ6c). In the species investigated. C18 acids were always present in greater quantities than C16 fatty acids; C20 and C22 acids were only minor components. The Cornaceae show differing fatty acid patterns which correlate well with anatomical, morphological and other chemical data. In Cornus, Curtisia, Mastixia and Corokia linoleic acid predominates, whereas linoleic and linolenic acid form the major components in Davidia and Nyssa. 18 : 1Δ6c, an aralioid type, occurs in large amounts in Aucuba and Griselinia. Hamamelis, Hydrangea and Ilex show a common fatty acid pattern with linoleic acid as the dominant component in all cases. Classification currently based on morphological and anatomical differences between the two species of Styracaceae which were investigated here should include their different fatty acid compositions: in Halesia linoleic acid predominates over oleic acid, whereas in Styrax equal amounts of these two acids are found. 相似文献

Ipheion, as recognized by Guaglianone (Darwiniana 17:159–242, 1972), is a small genus of the family Amaryllidaceae, subfamily Allioideae, tribe Gilliesieae endemic to South America. Since 1800, the species of Ipheion were treated under Beauverdia, Brodiaea, Milla, Nothoscordum, Tristagma or Triteleia. Nowadays, some species of Ipheion are treated as Tristagma and some other under Nothoscordum. In this paper, we analyzed the morphological variation among species of Ipheion and related genera using a numerical taxonomic approach based on overall similarity, to investigate the intergeneric and infrageneric variations to the circumscribed groups. Based on 141 operational taxonomic units and 51 morphological characters, multivariate analyses were performed. Results showed that Ipheion separated into two groups according to Guaglianone’s sectional treatment: Ipheion sect. Ipheion is morphologically more similar to the studied species of Tristagma, while I. sect. Hirtellum can be separated from Nothoscordum/Zoellnerallium and from Tristagma and allies. These a priori groupings were tested using discriminant and univariate analyses. Diagnostic characters were selected to differentiate groups. Previous taxonomic treatments are discussed and results are also evaluated using additional karyological and geographical data. 相似文献

A review is presented of the ticks of the Central African Republic (C.A.R.), based on unpublished data and a literature review. We consider as established in the C.A.R. two species of Argasidae (one species of each of the genera Carios and Ornithodoros) and 49 species of Ixodidae: 5 Ixodes, 11 Amblyomma, 2 Dermacentor, 9 Haemaphysalis, 4 Hyalomma, and 18 Rhipicephalus species, 3 of which belong to the subgenus Boophilus. Two of these species, one Amblyomma and one Dermacentor, may by now have disappeared from the country together with their hosts, the black and white rhinoceroses. Moreover, four other species of Ixodidae have been recorded, but are not necessarily established in the country, and 6 species of Ixodidae have apparently been reported incorrectly; the data for the occurrence of three other species of Ixodidae are uncertain. Rhipicephalus species in the C.A.R. present the greatest difficulties in identification, on the one hand because of uncertainties in taxonomy, particularly in the capensis group, on the other hand because of individual variability, which means that individual specimens cannot always be reliably identified to species. Examining the dissected and cleared gonopore structure of females helps, but is very time-consuming where large numbers are involved. Some of the species of the genus Haemaphysalis are also difficult to identify with certainty. There are only a few species of Hyalomma in the country. We revised also some old records of ticks in C.A.R., which we consider as unreliable and should be disregarded because of subsequent changes in taxonomy and nomenclature, unless the material is still available for examination. 相似文献

Characterization and Sequence Variation in the rDNA Region of Six Nematode Species of the Genus Longidorus (Nematoda) 总被引:1,自引:0,他引:1

Total DNA was isolated from individual nematodes of the species Longidorus helveticus, L. macrosoma, L. arthensis, L. profundorum, L. elongatus, and L. raskii collected in Switzerland. The ITS region and D1-D2 expansion segments of the 26S rDNA were amplified and cloned. The sequences obtained were aligned in order to investigate sequence diversity and to infer the phylogenetic relationships among the six Longidorus species. D1-D2 sequences were more conserved than the ITS sequences that varied widely in primary structure and length, and no consensus was observed. Phylogenetic analyses using the neighbor-joining, maximum parsimony and maximum likelihood methods were performed with three different sequence data sets: ITS1-ITS2, 5.8S-D1-D2, and combining ITS1-ITS2+5.8S-D1-D2 sequences. All multiple alignments yielded similar basic trees supporting the existence of the six species established using morphological characters. These sequence data also provided evidence that the different regions of the rDNA are characterized by different evolution rates and by different factors associated with the generation of extreme size variation. 相似文献
