New Palaearctic species of the tribe Thalassaphorurini Pomorski, 1998 (Collembola, Onychiuridae)  [cached]
Anatoly Babenko,Ayuna Chimitova,Sophya Stebaeva
ZooKeys , 2011, DOI: 10.3897/zookeys.126.1229
Abstract: The paper is devoted to a taxonomic revision of the genus Sensillonychiurus Pomorski et Sveenkova, 2006. Five new species of this genus, i.e. S. mirus sp. n., S. taimyrensis sp. n., S. vegae sp. n., S. vitimicus sp. n., and S. amuricus sp. n., as well as three new species of the related genus Allonychiurus Yoshii, 1995, i.e. A. subvolinensis sp. n., A. elikonius sp. n., and A. unisetosus sp. n. are being described from various regions of Eurasia. The diagnoses of both genera are amended to include described species. Two genera, Tantulonychiurus Pomorski, 1996 and Thibaudichiurus Weiner, 1996, are treated as junior synonyms of the genus Allonychiurus. Agraphorura eisi (Rusek, 1976) is transferred to Sensillonychiurus; Tantulonychiurus volinensis (Szeptycki, 1964) and T. asiaticus Babenko, 2007 to Allonychiurus. A review of morphological peculiarities of Sensillonychiurus is performed, comparisons with the other genera of Thalassaphorurini given, and a key to the known species provided.

International Journal of Speleology , 2005,
Abstract: A new species of Agraphorura (Collembola: Poduromorpha: Onychiuridae) from caves in the Nort-West of Venezuela is described. A.calvoi n. sp. can be distinguished from its congeners by the following combination of characters: antennal organ III with four papillae, 32/133/33343 dorsal pseudocellar formula, 3/000/0112 ventral pseudocellar, subcoxae each with two pseudocelli, postantennalorgan with 7-9 vesicles, unguiculus with a basal lamella, tibiotarsi I-III with 19,19,18 setae (distal whorl of 9 setae). A table with thedifferential characters, as well as an identifi cation key for all of the known species of Agraphorura are provided.
Compara??o das comunidades de Sminthuroidea e Onychiuridae (Collembola) entre plantio direto em três níveis de fertilidade, plantio convencional e um ecossistema natural (campo nativo) em Ponta Grossa, Paraná, Brasil

Revista Brasileira de Zoologia , 1999, DOI: 10.1590/S0101-81751999000100007
Abstract: this work had as objective to compare the communities of sminthuroidea and onychiuridae (collembola) among no-tillage in three fertility levels, conventional tillage and a natural ecosystem (native grassland). in the conventional tillage and in the no-tillage in area of medium fertility, the community of sminthuroidea had regular fluctuation along the period of the experiment, but wtth low densities. the no-tillage in area of high fertility presented a populational pick in the autumn; the no-tillage in area of low fertility, in the spring; and, the natural ecosystem, in the summer. as the final mean density of the population of sminthuroidea, was observed that the no-tillage in area of low fertility went numerically superior to the others, proceeded by the natural ecosystem, no-tillage in area of high fertility, conventional tillage, and, finally, no-tillage in area of medium fertility. onychiuridae had three populational picks in the no-tillage in area of low fertility: being a larger in the winter and other two, smaller in the summer and in the autumn. in the no-tillage in area of medium fertility presented only a populational pick in the winter. in the other treatments there was not significantly populational picks. in relation to the final mean density ofthe community of onychiuridae, the no-tillage plantation in area of low fertility was superior, proceeded by the other treatments of no-tillage, and, in third plan, the natural ecosystem and the conventional tillage.

Palaearctic origin of Leishmania
Kerr, Sara F;
Memórias do Instituto Oswaldo Cruz , 2000, DOI: 10.1590/S0074-02762000000100011
Abstract: the hypothesis of a palaearctic origin of leishmania in the early cenozoic, dispersal to the nearctic in the late eocene and to the neotropical in the pliocene is presented. it is further hypothesized that murid rodents and their immediate ancestors have been important mammalian reservoirs since the origination of leishmania. biochemical, molecular, biogeographical, entomological, mammalalogical and ecological support for these hypotheses are reviewed.

Collembola Poduromorpha do litoral de Maricá, Rio de Janeiro, Brasil
Fernandes, Liliane Henriques;Mendon?a, Maria Cleide de;
Revista Brasileira de Zoologia , 2004, DOI: 10.1590/S0101-81752004000100004
Abstract: new species and new occurrences of collembola poduromorpha in the littoral of maricá, state of rio de janeiro are recorded. from the 20 species collected, four are described and illustrated: mesaphorura maricaensis sp. nov. (onychiuridae); brachystomella ceciliae sp. nov. (brachystomellidae); arlesia intermedia sp. nov. and micranurida fluminensis sp. nov. (neanuridae). the genus doutnacia rusek, 1974 and micranurida b?rner, 1901 and the species xenylla maritima tullberg, 1869, acherontiella globulata thibaud & massoud, 1979, onychiurus cf. mariapetrae thibaud, 1993, friesea reducta denis, 1931, pseudachorutes difficilis denis, 1931 are recorded for the first time to brazil. the high number of species and the record of the 16 new occurrences in this area shows the scarcity of the taxonomic studies and the elevated biodiversity of the poduromorpha at sand dunes.
MOSCHweb — a matrix-based interactive key to the genera of the Palaearctic Tachinidae (Insecta, Diptera)  [cached]

ZooKeys , 2012, DOI: 10.3897/zookeys.205.3409
Abstract: We provide a general overview of features and technical specifications of an original interactive key web application for the identification of Palaearctic Tachinidae genera. The full list of terminal taxa included in the key, which is the most updated list of genera currently recorded for the Palaearctic Region, is given. We also briefly discuss the need for dealing with detailed and standardized taxa descriptions as a base to keep matrix-based interactive tools easily updated, by proposing a standardized protocol.
Effects of Afforestation with Pines on Collembola Diversity in the Limestone hills of Szárhalom (West Hungary)
WINKLER, Dániel,TóTH, Viktória
Acta Silvatica & Lignaria Hungarica , 2012,
Abstract: We investigated the responses of collembolan communities to pine afforestation in an area formerly characterized by a mosaic of autochthonous downy oak woodland and steppe meadows. Study sites were selected in mixed stands of black pine and Scots pine and control samples were taken from downy oak stands and open steppe meadows. A total of 1884 Collembola specimens belonging to 66 species were collected. Three species, namely Protaphorura pannonica (Onychiuridae), Tomocerus mixtus (Tomoceridae) and Isotoma caerulea (Isotomidae) proved to be new to the Hungarian fauna. There are typical Collembola communities which are specific to different habitat types where species of a given composition can only or predominantly be found in that habitat, as well as some basic common species which occur in every habitat. The highest species richness (41) was found in steppe meadows, considerably lower (34) in downy oak forests, reaching the lowest value (25) in pine plantations. Although several forest species present in the oak woodland were completely missing from the pine forests, there was no significant difference between the Collembola diversities of the two forest habitats. The difference became more prominent in collembolan abundance which resulted in less than half of individuals/m2 in pine plantations compared to the soils of downy oak forests, most likely due to the changed soil conditions, especially of humus characteristics, caused by the pine needle litter. Jaccard similarity measure indicated approximately equal similarity (0.24–0.28) for paired comparison, suggesting that a relatively constant 'basic Collembola community' determined by the soil type typical for the area is present; while dissimilarity in communities between sites are partly provided by spatial heterogeneity of open and forest habitats and by the difference of the vegetation type.
Further support for a palaearctic origin of Leishmania
Kerr, Sara F;Merkelz, Robert;MacKinnon, Christy;
Memórias do Instituto Oswaldo Cruz , 2000, DOI: 10.1590/S0074-02762000000400022
Abstract: the fossil record and systematics of murid rodents, reservoirs of zoonotic cutaneous leishmaniasis in the palaearctic, oriental, african, nearctic and neotropical, strongly support a palaearctic origin of leishmania. the fossil record and systematics of phlebotomine sand flies reinforce this idea. interpretations of molecular data that place the origin of leishmania in the neotropical are inconsistent with the natural histories of reservoirs and vectors. the evolutionary pattern of new world rats (sigmodontinae) indicates that they may be the most important reservoirs of zoonotic cutaneous leishmaniasis throughout their range.
