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

obsoletus, Atimia
confusa
confusa, Callidium
frigidum, Phymatodes
testaceus, and Xylotrechus
sagittatus
sagittatus were captured almost exclusively in traps near (1 m above) the forest floor. These results highlight the importance of sampling both the understory and upper canopy when using traps for surveying diversity of Cerambycidae. 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

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

Third instar larvae of members of the Ceratitis FAR complex, including Ceratitis
fasciventris (Bezzi), Ceratitis
anonae Graham, and Ceratitis
rosa Karsch are described and compared with those of Ceratitis
capitata (Wiedemann). Diagnostic characters, such as presence vs. absence of a secondary tooth on the mandibles, previously used to separate Ceratitis
capitata from Ceratitis
rosa, are shown to vary in each species. Significant variation in diagnostic morphological characters among populations of Ceratitis
rosa from east and south Africa is documented; however, the differences are not simply congruent with the R1 and R2 designations based on other studies. Quantitative measures of numerous morphological characters are consistently smaller in the larvae of Ceratitis
fasciventris and distinguish them from other species of the FAR complex. Larvae of Ceratitis
capitata can be distinguished from those of the FAR complex by characters such as absence of accessory plates of the oral ridges, the shape of the anterior spiracle, and the pattern of dorsal spinules. Previous studies indicated that absence of accessory lobes separate the genus Ceratitis from Bactrocera, but this is shown to be incorrect, as accessory lobes are in fact present in several species of Ceratitis. 相似文献

Coexistence of closely related species may be promoted by niche differentiation or result from interspecific trade-offs in life history and ecological traits that influence relative fitness differences and contribute to competitive inequalities. Although insufficient to prove coexistence, trait comparisons provide a first step to identify functional differences between co-occurring congeneric species in relation to mechanisms of coexistence. Here, a comparative review on life history and ecological traits is presented for two pairs of co-occurring species of spiny lobsters in the genus Panulirus: Panulirus
gracilis and Panulirus
inflatus from the Eastern Central Pacific region, and Panulirus
argus and Panulirus
guttatus from the Caribbean region. Panulirus
gracilis and Panulirus
inflatus have similar larval, postlarval, and adult sizes and a similar diet, but differ in degree of habitat specialization, fecundity, and growth rate. However, little is known on behavioral traits of these two species that may influence their competitive abilities and susceptibility to predators. The more abundant information on Panulirus
argus and Panulirus
guttatus shows that these two species differ more broadly in degree of habitat specialization, larval, postlarval and adult sizes, diet, fecundity, growth rate, degree of sociality, defense mechanisms, susceptibility to predators, and chemical ecology, suggesting a greater degree of niche differentiation between Panulirus
argus and Panulirus
guttatus than between Panulirus
gracilis and Panulirus
inflatus. Whether the substantial niche differentiation and apparent interspecific trade-offs between Panulirus
argus and Panulirus
guttatus relative to Panulirus
gracilis and Panulirus
inflatus reflect an earlier divergence of the former pair of species in the evolution of the genus constitutes an intriguing hypothesis. However, whether or not post-divergence evolution of each species pair occurred in sympatry remains uncertain. 相似文献

Vietnamese species from the family Plectopylidae are revised based on the type specimens of all known taxa, more than 600 historical non-type museum lots, and almost 200 newly-collected samples. Altogether more than 7000 specimens were investigated. The revision has revealed that species diversity of the Vietnamese Plectopylidae was previously overestimated. Overall, thirteen species names (anterides Gude, 1909, bavayi Gude, 1901, congesta Gude, 1898, fallax Gude, 1909, gouldingi Gude, 1909, hirsuta Möllendorff, 1901, jovia Mabille, 1887, moellendorffi Gude, 1901, persimilis Gude, 1901, pilsbryana Gude, 1901, soror Gude, 1908, tenuis Gude, 1901, verecunda Gude, 1909) were synonymised with other species. In addition to these, Gudeodiscus
hemmeni
sp. n. and Gudeodiscus
messageri
raheemi
ssp. n. are described from north-western Vietnam. Sixteen species and two subspecies are recognized from Vietnam. The reproductive anatomy of eight taxa is described. Based on anatomical information, Halongella
gen. n. is erected to include Plectopylis
schlumbergeri and Plectopylis
fruhstorferi. Additionally, the genus Gudeodiscus is subdivided into two subgenera (Gudeodiscus and Veludiscus
subgen. n.) on the basis of the morphology of the reproductive anatomy and the radula. The Chinese Gudeodiscus
phlyarius
werneri Páll-Gergely, 2013 is moved to synonymy of Gudeodiscus
phlyarius. A spermatophore was found in the organ situated next to the gametolytic sac in one specimen. This suggests that this organ in the Plectopylidae is a diverticulum. Statistically significant evidence is presented for the presence of calcareous hook-like granules inside the penis being associated with the absence of embryos in the uterus in four genera. This suggests that these probably play a role in mating periods before disappearing when embryos develop. Sicradiscus
mansuyi is reported from China for the first time. 相似文献

The geographic distribution of the genus Lophoproctus Pocock, 1894 has greatly expanded with new records of the species Lophoproctus
coecus Pocock, 1894, together with the reassignment of a number of millipedes formerly identified as Lophoproctus
lucidus (Chalande, 1888). Lophoproctus
coecus was found to be the sole representative of the family Lophoproctidae in collections examined from Crimea and the Caucasian region. The species was also identified from Iran and Kyrgyzstan. Lophoproctus specimens collected in Italy by Verhoeff were reassigned as Lophoproctus
coecus with the exception of one specimen of Lophoproctus
jeanneli (Brölemann, 1910) from Capri. These data were combined with all available information from the literature to look at the pattern of distribution of the four species in the genus. The range of the genus Lophoproctus extends from Portugal to Central Asia. Lophoproctus
coecus is widespread from Italy eastward, while the morphologically very similar species Lophoproctus
lucidus is confined to France and northern Africa. The two species have a narrow overlap in the Alpes Maritimes region of France. Lophoproctus
jeanneli has a scattered coastal distribution around the Mediterranean Sea. The troglobitic species Lophoproctus
pagesi (Condé, 1982) has only been recorded from a cave on Majorca, Spain. 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

Members of the genus Parachironomus Lenz known from China and Japan are revised, and a key to their male adults is given. Parachironomus
poyangensis
sp. n. is described in this life stage. Parachironomus
frequens (Johannsen) and Parachironomus
monochromus (van der Wulp) are recorded from China for the first time, thus are redescribed from Chinese specimens. Parachironomus
kamaabeus Sasa & Tanaka and Parachironomus
toneabeus Sasa & Tanaka are new junior synonyms of Parachironomus
frequens. Three Chinese or Japanese species formerly placed in Parachironomus are transferred to other genera, resulting in the new combinations Cryptochironomus
inafegeus (Sasa, Kitami & Suzuki), Demicryptochironomus (Irmakia) lobus (Yan, Sæther, Jin & Wang), and Microchironomus
lacteipennis (Kieffer). Chironomus
sauteri Kieffer, Parachironomus
kisobilobalis Sasa & Kondo and Parachironomus
kuramaexpandus Sasa are removed from Parachironomus; the last of these three denotes a valid species of uncertain generic placement, the first two are nomina dubia. 相似文献

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

We describe Lonchophylla
inexpectata
sp. n. from the Caatinga of Brazil. This new species can be distinguished from all known species of Lonchophylla that occur in Brazil by dental traits, cranial size, and fur colour. Specimens of Lonchophylla
inexpectata have been misidentified as Lonchophylla
mordax; but Lonchophylla
inexpectata is a pale-venter species, similar in external appearance to Lonchophylla
dekeyseri. We have found Lonchophylla
inexpectata in the Caatinga of North-eastern Brazil; Lonchophylla
mordax along the eastern border of the Caatinga and in the Atlantic Forest–Caatinga ecotone in North-eastern Brazil; and Lonchophylla
dekeyseri in the Cerrado of Mid-western Brazil, in the Brazilian Cerrado–Caatinga ecotone, and as far west as the Cerrado of Bolivia. 相似文献

Mandibular mechanisms in Geophilomorpha are revised based on three-dimensional reconstructions of the mandibulo-tentorial complex and its muscular equipment in Dicellophilus
carniolensis (Placodesmata) and Hydroschendyla
submarina (Adesmata). Tentorial structure compares closely in the two species and homologies can be proposed for the 14/17 muscles that attach to the tentorium. Both species retain homologues of muscles that in other Pleurostigmophora are traditionally thought to cause swinging movements of the tentorium that complement the mobility of the mandibles. Although the original set of tentorial muscles is simplified in Geophilomorpha, the arrangement of the preserved homologues conforms to a system of six degrees of freedom of movement, as in non-geophilomorph Pleurostigmophora. A simplification of the mandibular muscles is confirmed for Geophilomorpha, but our results reject absence of muscles that in other Pleurostigmophora primarily support see-saw movements of the mandibles. In the construction of the tentorium, paralabial sclerites seem to be involved in neither Placodesmata nor Adesmata, and we propose their loss in Geophilomorpha as a whole. Current insights on the tentorial skeleton and its musculature permit two alternative conclusions on their transformation in Geophilomorpha: either tentorial mobility is primarily maintained in both Placodesmata and Adesmata (contrary to Manton’s arguments for immobility), or the traditional assumption of the tentorium as being mobile is a misinterpretation for Pleurostigmophora as a whole. 相似文献

Five bee-fly species (Bombyliidae, Diptera) have been listed in this paper as new to the Kingdom of Saudi Arabia. Four of the recorded species have been identified to the level of species, namely: Bombomyia
discoidea (Fabricius, 1794), Spogostylum
candidum (Sack, 1909), Exoprosopa
linearis Bezzi, 1924, and Exoprosopa
minos (Meigen, 1804), while the fifth one only to genus, Desmatoneura sp. The species have been collected from Al-Baha and Asir Provinces in the south-western part of the Kingdom. One of the four identified species, Exoprosopa
linearis, has an Afrotropical affinity, and another two, Spogostylum
candidum and Bombomyia
discoidea, have considerable Afrotropical distributions, and this result agrees to some extent with studies considering these parts of the Arabian Peninsula, including Al-Baha and Asir Provinces, having Afrotropical influences and may be included in the Afrotropical Region rather than in the Palaearctic Region or the Eremic zone. 相似文献

The taxonomy of the polytypic and wide-ranging Gray-necked Wood-rail, Aramides
cajaneus is reviewed, based on external morphology and voice. Throughout its distribution, there is extensive plumage variation, much of it taxonomically uninformative. However, through three informative plumage characters, as well as morphometric and vocal variation, three phylogenetic species were identified within what is today known as Aramides
cajaneus, all of which already had available names: Aramides
albiventris Lawrence, 1868, from southern Mexico to northeastern Costa Rica, Aramides
cajaneus (Statius Müller, 1776) (sensu stricto), from southwestern Costa Rica to Argentina, and Aramides
avicenniae Stotz, 1992, from a small section of the coast of southeastern Brazil. Aramides
albiventris presents extensive plumage variation, but with no geographic structure. The song of Aramides
cajaneus and Aramides
avicenniae is strikingly and completely different from the song of Aramides
albiventris. A previously unnoticed parapatric pattern of distribution of Aramides
cajaneus and its congener Aramides
saracura in southeastern Brazil is described, and we clarify that the name Aramides
plumbeicollis, included in the synonymy of Aramides
albiventris, was first made available in 1892, rather than in 1888 as is widely referred. In addition, plumage variation in Aramides
ypecaha, Aramides
wolfi, and Aramides
mangle is discussed. 相似文献
