Hemibrycon
sanjuanensis, new species, is described from the upper San Juan River drainage, Pacific versant, Colombia. It is distinguished from Hemibrycon
boquiae, Hemibrycon
brevispini, Hemibrycon
cairoense, Hemibrycon
colombianus, Hemibrycon
mikrostiktos, Hemibrycon
metae, Hemibrycon
palomae, Hemibrycon
rafaelense and Hemibrycon
tridens by the presence of a circular or oblong humeral spot that is located two scales posterior to the opercle (vs. 3–4 scales in Hemibrycon
palomae, Hemibrycon
rafaelense, Hemibrycon
brevispini and Hemibrycon
cairoense, and 0–1 scales, in Hemibrycon
metae and Hemibrycon
boquiae). It further differs from Hemibrycon
colombianus in having a round or oblong humeral spot (vs. rectangular). It differs from Hemibrycon

taeniurus, Hemibrycon
tridens, and Hemibrycon
yacopiae in having melanophores on the posterior margins of the scales along the sides of body (vs. lacking melanophores on margins of scales along entire length of the sides of body). The new species differs from all congeners mentioned above in having, among other features, six teeth in the outer premaxillary row arranged in a straight line (vs. five or fewer teeth not arranged in straight line except Hemibrycon

The C. parapsilosis sensu lato group involves three closely related species, C. parapsilosis sensu stricto,
C
. orthopsilosis
and
C
. metapsilosis
. Although their overall clinical importance is dramatically increasing, there are few studies regarding the virulence properties of the species of the psilosis complex. In this study, we tested 63 C. parapsilosis sensu stricto, 12
C
. metapsilosis
and 18
C
. orthopsilosis
isolates for the ability to produce extracellular proteases, secrete lipases and form pseudohyphae. Significant differences were noted between species, with the
C
. metapsilosis
strains failing to secrete lipase or to produce pseudohyphae. Nine different clinical isolates each of C. parapsilosis sensu stricto,
C
. orthopsilosis
and
C
. metapsilosis
were co-cultured with immortalized murine or primary human macrophages. C. parapsilosis sensu stricto isolates showed a significantly higher resistance to killing by primary human macrophages compared to
C
. orthopsilosis
and
C
. metapsilosis
isolates. In contrast, the killing of isolates by J774.2 mouse macrophages did not differ significantly between species. However, C. parapsilosis sensu stricto isolates induced the most damage to murine and human macrophages, and
C
. metapsilosis
strains were the least toxic. Furthermore, strains that produced lipase or pseudohyphae were most resistant to macrophage-mediated killing and produced the most cellular damage. Finally, we used 9 isolates of each of the C. parapsilosis sensus lato species to examine their impact on the survival of
Galleria
mellonella
larvae. The mortality rate of
G
. mellonella
larvae infected with
C
. metapsilosis
isolates was significantly lower than those infected with C. parapsilosis sensu stricto or
C
. orthopsilosis
strains. Taken together, our findings demonstrate that
C
. metapsilosis
is indeed the least virulent member of the psilosis group, and also highlight the importance of pseudohyphae and secreted lipases during fungal-host interactions. 相似文献

The tiger beetle assemblage of the wetlands of La Mancha (central Spain) comprises nine species: Calomera
littoralis
littoralis, Cephalota
maura
maura, Cephalota
circumdata
imperialis, Cephalota
dulcinea, Cicindela
campestris
campestris, Cicindela
maroccana, Cylindera
paludosa, Lophyra
flexuosa
flexuosa, and Myriochila
melancholica
melancholica. This assemblage represents the largest concentration of tiger beetles in a single 1º latitude / longitude square in Europe. General patterns of spatial and temporal segregation among species are discussed based on observations of 1462 specimens registered during an observation period of one year, from April to August. The different species of Cicindelini appear to be distributed over space and time, with little overlapping among them. Three sets of species replace each other phenologically as the season goes on. Most of the species occupy drying or dried salt lakes and salt marshes, with sparse vegetation cover. Spatial segregation is marked in terms of substrate and vegetation use. Calomera
littoralis and Myriochila
melancholica have been observed mainly on wet soils; Cephalota
circumdata on dry open saline flats; Cephalota
dulcinea and Cylindera
paludosa in granulated substrates with typical halophytic vegetation; Cephalota
maura is often present in man-modified areas. Cephalota
circumdata and Cephalota
dulcinea are included as species of special interest in the list of protected species in Castilla–La Mancha. Conservation problems for the Cicindelini assemblage arise from agricultural activities and inadequate use of sport vehicles. Attempts at restoring the original habitat, supressing old semi-industrial structures, may affect the spatial heterogeneity of the lakes, and have an effect on Cicindelinae diversity. 相似文献

The phylogenetic relationships of the genera of Listroderini LeConte, 1876 are analyzed based on 58 morphological characters. The genera are grouped in four clades, which are given subtribal status: Macrostyphlina new subtribe (Adioristidius, Amathynetoides, Andesianellus, Macrostyphlus, Nacodius and Puranius), Palaechthina Brinck, 1948 (Anorthorhinus, Gunodes, Haversiella, Inaccodes, Listronotus, Neopachytychius, Palaechthus, Palaechtodes, Steriphus and Tristanodes), Falklandiina new subtribe (Falklandiellus, Falklandiopsis, Falklandius, Gromilus, Lanteriella, Liparogetus, Nestrius and Telurus), and Listroderina (Acroriellus, Acrorius, Acrostomus, Antarctobius, Germainiellus, Hyperoides, Lamiarhinus, Listroderes, Methypora, Philippius, Rupanius and Trachodema). The subtribes are characterized and keys to identify them and their genera are provided. Listroderini have four main biogeographical patterns: Andean (Macrostyphlina), Andean-New Zealand (Falklandiina), Andean-Neotropical-Australian (Listroderina) and Andean-Neotropical-Australian-New Zealand-Nearctic-Tristan da Cunha-Gough islands (Palaechthina). Geographical paralogy, particularly evident in the Subantarctic subregion of the Andean region, suggests that Listroderini are an ancient Gondwanic group, in which several extinction events might have obscured relationships among the areas. 相似文献

The elongatus-kriegi complex is one of the most diverse clades of the Liolaemus (sensu stricto) subgenus of lizards. There are currently 29 species recognized in this group distributed between Chile and Argentina. Based on molecular evidence, there seem to be five main clades nested within this complex: the elongatus, leopardinus, kriegi, petrophilus and punmahuida clades. Liolaemus
buergeri and Liolaemus
kriegi, both of the kriegi clade, were believed to inhabit the surroundings of the Laja Lagoon, in the Biobío Region of Chile. Moreover, this Chilean population of Liolaemus
kriegi was recently recognized as an undescribed taxon called “Liolaemus sp. A” based on molecular phylogenetics. In this work, we studied these two populations of the Laja Lagoon and provided the morphological diagnosis to describe them as two new species: Liolaemus
scorialis
sp. n. and Liolaemus
zabalai
sp. n., previously considered Liolaemus
buergeri and “Liolaemus
kriegi/Liolaemus sp. A” respectively. Additionally, we identified another population of Liolaemus
scorialis in the vicinity of La Mula Lagoon in the Araucanía Region of Chile. Liolaemus
scorialis differs from almost all of the species of the elongatus-kriegi complex by its considerably smaller size. Nevertheless, without molecular data we cannot assign it to any particular subclade. Liolaemus
zabalai belongs to the kriegi clade based on published molecular phylogenies. Finally, we provide some natural history data on both species and we document for the first time the presence of Liolaemus
neuquensis in Chile from a museum specimen from La Mula Lagoon. 相似文献

feai (Borchmann, 1911), Xenocerogria
ignota (Borchmann, 1941) and Xenocerogria
ruficollis (Borchmann, 1912). Xenocera
xanthisma Chen, 2002 is proposed as a junior synonym of Xenocerogria
ruficollis. Lectotype of Xenocerogria
ignota is designated, and the species is transferred to the genus Lagria Fabricius, 1775. New Chinese province records of Xenocerogria

The diversity of Diplopoda in caves of southern China is remarkably high, often 5–6 species per cave, consisting mostly of local endemics and presumed troglobionts. These are evidently biased to just a few lineages, mainly members of the orders Chordeumatida and Callipodida, the families Cambalopsidae (Spirostreptida) and Haplodesmidae (Polydesmida) or the genera Pacidesmus, Epanerchodus and Glenniea (all Polydesmida, Polydesmidae), Trichopeltis (Polydesmida, Cryptodesmidae), Dexmoxytes (Polydesmida, Paradoxosomatidae) and Hyleoglomeris (Glomerida, Glomeridae). All these taxa, especially the Paradoxosomatidae and Cambalopsidae (usually amounting to about 60% and 10% of the total species diversity in the Oriental fauna, respectively), are moderately to highly speciose across Southeast Asia, being largely epigean. However, the epigean Diplopoda of southern China are yet badly understudied, since much of the collecting and taxonomic exploration efforts still focus on cavernicoles. The Oriental Region is the only biogeographic realm globally that harbours all 16 orders of Diplopoda, of which 14 have already been encountered in China and/or the immediately adjacent parts of Indochina. Thus, China may actually prove to support no less than 1,000 millipede species of various origins, mainly Oriental and Palaearctic. 相似文献

The Madagascar periwinkle (
Catharanthus
roseus
in the family Apocynaceae) is an important medicinal plant and is the source of several widely marketed chemotherapeutic drugs. It is also commonly grown for its ornamental values and, due to ease of infection and distinctiveness of symptoms, is often used as the host for studies on phytoplasmas, an important group of uncultivated plant pathogens. To gain insights into the characteristics of apocynaceous plastid genomes (plastomes), we used a reference-assisted approach to assemble the complete plastome of
C
. roseus
, which could be applied to other
C
. roseus
-related studies. The
C
. roseus
plastome is the second completely sequenced plastome in the asterid order Gentianales. We performed comparative analyses with two other representative sequences in the same order, including the complete plastome of
Coffea
arabica
(from the basal Gentianales family Rubiaceae) and the nearly complete plastome of
Asclepias
syriaca
(Apocynaceae). The results demonstrated considerable variations in gene content and plastome organization within Apocynaceae, including the presence/absence of three essential genes (i.e., accD, clpP, and ycf1) and large size changes in non-coding regions (e.g., rps2-rpoC2 and IRb-ndhF). To find plastome markers of potential utility for
Catharanthus
breeding and phylogenetic analyses, we identified 41
C
. roseus
-specific simple sequence repeats. Furthermore, five intergenic regions with high divergence between
C
. roseus
and three other euasterids I taxa were identified as candidate markers. To resolve the euasterids I interordinal relationships, 82 plastome genes were used for phylogenetic inference. With the addition of representatives from Apocynaceae and sampling of most other asterid orders, a sister relationship between Gentianales and Solanales is supported. 相似文献

aceris, Tylonotus
bimaculatus, Lepturges
angulatus, Lepturges
symmetricus, Urgleptes
signatus (NS), and Pogonocherus
parvulus were detected exclusively in traps deployed in the forest canopy, and most individuals of Oplosia

The Neotropical genus Cephaloleia Chevrolat (Coleoptera: Chrysomelidae: Cassidinae) includes 214 species distributed from the south of Mexico to Argentina. Cephaloleia beetles feed mostly on plants from the order Zingiberales. The interactions between Cephaloleia beetles and their Zingiberales host plants is proposed as one of the oldest and most conservative associations. Here we describe a new species of Cephaloleia (Cephaloleia
kuprewiczae
sp. n.) that feeds on two species of bromeliads (Pitcairnia
arcuata and Pitcairnia
brittoniana, Bromeliaceae: Pitcairnioideae). Cephaloleia
kuprewiczae was previously described as Cephaloleia
histrionica. This study includes evidence from DNA barcodes (COI), larval and adult morphology and insect diets that separates Cephaloleia
kuprewiczae from Cephaloleia
histrionica as a new species. 相似文献

The New World genus Philonome Chambers, 1874 is revised. This genus comprises twelve species, seven of which are described as new: two species, Philonome
nigrescens
sp. n. and Philonome
wielgusi
sp. n., from the United States; four species, Philonome
albivittata
sp. n., Philonome
curvilineata
sp. n., Philonome
kawakitai
sp. n., and Philonome
lambdagrapha
sp. n., from French Guiana; and one species, Philonome
penerivifera
sp. n., from Brazil. Lectotypes are designated for Philonome
clemensella Chambers, 1874 and Philonome
rivifera Meyrick, 1915. Partially on evidence of their head morphology and particularly from molecular evidence, the genus Philonome, previously associated with Bucculatricidae or Lyonetiidae, is reassigned to Tineidae. A possible systematic position of Philonome within Tineidae is discussed. Eurynome Chambers, 1875, is synonymized with Argyresthia Hübner, 1825 (Argyresthiidae). Photographs of adults and illustrations of genitalia, when available, are provided for all described species of Philonome and two species previously misplaced in Philonome, Argyresthia
luteella (Chambers, 1875) and Elachista
albella (Chambers, 1877). In addition, DNA barcodes were used for the delimitation of most species. 相似文献

Muricea is an amphi-American genus. Verrill proposed dividing the species from the Pacific Ocean into three genera and established the genus Eumuricea for five eastern Pacific species with tubular calyces. Eumuricea is basically characterized by colonies with elongate, cylindrical calyces with truncate margins and star-like opercula, and the occurrence of unilateral spinous spindles. According to these characteristics, Eumuricea does not show enough difference from Muricea to be treated as a separate genus. Original type material of Eumuricea was morphologically analysed and illustrated using optical and scanning electron microscopy. We conclude that the eastern Pacific species should be placed in the genus Muricea and form a group characterised by tubular calyces that comprises four species at present, Muricea
acervata, Muricea
hispida, Muricea
squarrosa, and Muricea
tubigera and a dubious species Muricea
horrida. Lectotypes were designated for Muricea
squarrosa and Muricea
hispida to establish their taxonomic status. The genus Eumuricea has also been misunderstood by former authors who erroneously assigned species to it. For these species we propose new combinations: Swiftia
pusilla, Astrogorgia
splendens and Astrogorgia
ramosa. 相似文献

Methodological improvements now allow routine analyses of highly degraded DNA samples as found in museum specimens. Using these methods could be useful in studying such groups as rodents of the genus Gerbillus for which i) the taxonomy is still highly debated, ii) collection of fresh specimens may prove difficult. Here we address precise taxonomic questions using a small portion of the cytochrome b gene obtained from 45 dry skin/skull museum samples (from 1913 to 1974) originating from two African and three Asian countries. The specimens were labelled Gerbillus
gerbillus, Gerbillus
andersoni, Gerbillus
nanus, Gerbillus
amoenus, Gerbillus
perpallidus and Gerbillus
pyramidum, and molecular results mostly confirmed these assignations. The close relationship between Gerbillus
nanus (Asian origin) and Gerbillus
amoenus (African origin) confirmed that they represent vicariant sibling species which differentiated in allopatry on either side of the Red Sea. In the closely related Gerbillus
perpallidus and Gerbillus
pyramidum, specimens considered as belonging to one Gerbillus
pyramidum subspecies (Gerbillus
pyramidum
floweri) appeared closer to Gerbillus
perpallidus suggesting that they (Gerbillus
pyramidum
floweri and Gerbillus
perpallidus) may represent a unique species, distributed on both sides of the Nile River, for which the correct name should be Gerbillus
floweri. Furthermore, the three other Gerbillus
pyramidum subspecies grouped together with no apparent genetic structure suggesting that they may not yet represent genetically differentiated lineages. This study confirms the importance of using these methods on museum samples, which can open new perspectives in this particular group as well as in other groups of interest. 相似文献
