This systematic study documents the taxonomy, diversity, and distribution of the tarantula spider genus Aphonopelma Pocock, 1901 within the United States. By employing phylogenomic, morphological, and geospatial data, we evaluated all 55 nominal species in the United States to examine the evolutionary history of Aphonopelma and the group’s taxonomy by implementing an integrative approach to species delimitation. Based on our analyses, we now recognize only 29 distinct species in the United States. We propose 33 new synonymies (Aphonopelma

Our proposed species tree based on Anchored Enrichment data delimits five major lineages: a monotypic group confined to California, a western group, an eastern group, a group primarily distributed in high-elevation areas, and a group that comprises several miniaturized species. Multiple species are distributed throughout two biodiversity hotspots in the United States (i.e., California Floristic Province and Madrean Pine-Oak Woodlands). Keys are provided for identification of both males and females. By conducting the most comprehensive sampling of a single theraphosid genus to date, this research significantly broadens the scope of prior molecular and morphological investigations, finally bringing a modern understanding of species delimitation in this dynamic and charismatic group of spiders. 相似文献

The cotton aphid, Aphis
gossypii, is one of the most biologically diverse species of aphids; a polyphagous species in a family where most are host specialists. It is economically important and belongs to a group of closely related species that has challenged aphid taxonomy. The research presented here seeks to clarify the taxonomic relationships and status of species within the Aphid
gossypii group in the North American Midwest. Sequences of the mitochondrial cytochrome oxidase 1 (COI), nuclear elongation factor 1-α (EF1-α), and nuclear sodium channel para-type (SCP) genes were used to differentiate between Aphid
gossypii and related species. Aphis
monardae, previously synonymised with Aphid
gossypii, is re-established as a valid species. Phylogenetic analyses support the close relationship of members of the Aphid
gossypii group native to North America (Aphid
forbesi, Aphid
monardae, Aphid
oestlundi, Aphid
rubifolii, and Aphid
rubicola), Europe (Aphid
nasturtii, Aphid
urticata and Aphid
sedi), and Asia (Aphid
agrimoniae, Aphid
clerodendri, Aphid
glycines, Aphid
gossypii, Aphid
hypericiphaga, Aphid
ichigicola, Aphid
ichigo, Aphid
sanguisorbicola, Aphid
sumire and Aphid
taraxicicola). The North American species most closely related to Aphid
gossypii are Aphid
monardae and Aphid
oestlundi. The cosmopolitan Aphid
gossypii and Aphid
sedi identified in the USA are genetically very similar using COI and EF1-α sequences, but the SCP gene shows greater genetic distance between them. We present a discussion of the biological and morphological differentiation of these species. 相似文献

Taxonomic changes are made for several problematic Australian Carabidae in the tribes Harpalini, Abacetini, Pterostichini, and Oodini. Examination of types resulted in the synonymy of Veradia Castelnau, 1867 with Leconomerus Chaudoir, 1850; Nelidus Chaudoir, 1878, Feronista Moore, 1965, and Australomasoreus Baehr, 2007 with Cerabilia Castelnau, 1867; and newly combining Fouquetius
variabilis Straneo, 1960 in the genus Pediomorphus Chaudoir, 1878; Australomasoreus
monteithi Baehr, 2007 in the genus Cerabilia Castelnau, 1867; and Anatrichis
lilliputana W.J. Macleay, 1888 in the genus Nanodiodes Bousquet, 1996. Cuneipectus Sloane, 1907 is placed in Pterostichini Bonelli, 1810, which is a senior synonym of Cuneipectini Sloane, 1907. 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

The New World tropics represents the most diverse region for tachinid parasitoids (Diptera: Tachinidae), but it also contains the most narrowly defined, and possibly the most confusing, tachinid genera of any biogeographic region. This over-splitting of genera and taxonomic confusion has limited progress toward our understanding the family in this region and much work is needed to revise, redefine, and make sense of the profusion of finely split taxa. In a recent analysis of the Neotropical genus Erythromelana Townsend, two species previously assigned to this genus, Euptilodegeeria
obumbrata (Wulp) and Myiodoriops
marginalis Townsend were reinstated as monotypic genera. In the present study, we demonstrate that Euptilodegeeria
obumbrata (Wulp), previously assigned to three different genera, represents in fact a species of the large New World genus Eucelatoria Townsend, in which females possess a sharp piercer for oviposition. We also show that the species Eucelatoria
carinata (Townsend) belongs to the same species group as Eucelatoria
obumbrata, which we here define and characterize as the Eucelatoria
obumbrata species group. Additionally, we describe Eucelatoria
flava
sp. n. as a new species within the Eucelatoria
obumbrata species group. Finally, we redescribe the genus Myiodoriops Townsend and the single species Myiodoriops
marginalis Townsend. 相似文献

New species are described in the genera Wormaldia (Trichoptera, Philopotamidae) and Drusus (Trichoptera, Limnephilidae, Drusinae). Additionally, the larva of the new species Drusus
crenophylax
sp. n. is described, and a key provided to larval Drusus species of the bosnicus-group, in which the new species belongs. Observations on the threats to regional freshwater biodiversity and caddisfly endemism are discussed.The new species Wormaldia
sarda
sp. n. is an endemic of the Tyrrhenian island of Sardinia and differs most conspicuously from its congeners in the shape of segment X, which is trilobate in lateral view. The new species Drusus
crenophylax
sp. n. is a micro-endemic of the Western Balkans, and increases the endemism rate of Balkan Drusinae to 79% of 39 species. Compared to other Western Balkan Drusus, males of the new species are morphologically most similar to Drusus
discophorus Radovanovic and Drusus
vernonensis Malicky, but differ in the shape of superior and intermediate appendages. The females of Drusus
crenophylax
sp. n. are most similar to those of Drusus
vernonensis, but differ distinctly in the outline of segment X. Larvae of Drusus
crenophylax sp. n. exhibit toothless mandibles, indicating a scraping grazing-feeding ecology. 相似文献

We carried out a quantitative assessment of the consumption of herbaceous plants by Opatrum
sabulosum (Linnaeus, 1761) – a highly significant agricultural pest species. We researched the feeding preferences of this pest species with respect to 33 uncultivated and 22 cultivated plant species. This species of darkling beetle feeds on many uncultivated plant species, including those with hairy leaves and bitter milky sap, such as Scabiosa
ucrainca (5.21 mg/specimen/24 hours), Euphorbia
virgata (3.45), Solanum
nigrum (3.32), Centauria
scabiosa (2.47), Lamium
album (2.41), Aristolochia
clematitis (1.76), Chenopodium
album (1.73), Arctium
lappa (1.51), Asperula
odorata (1.20). A high rate of leaf consumption is also characteristic for cultivated species, for example, Perilla
nankinensis (5.05 mg/specimen/24 hours), Lycopersicon
esculentum (3.75), Tropaeolum
majus (3.29), Nicotiana
tabacum (2.66), Rumex
acetosa (1.96), Beta
vulgaris (1.27). Opatrum
sabulosum is capable of feeding on plants which are poisonous to cattle. This species of darkling beetle consumes 95.5% of the cultivated and 48.5% of the uncultivated herbaceous plants researched. 相似文献

All genus-group names listed in the second edition of the catalogue (1833-1836) of Dejean’s beetle collection are recorded. For each new genus-group name the originally included available species are listed and for generic names with at least one available species, the type species and the current status are given. Names available prior to the publication of Dejean’s second catalogue (1833-1836) are listed in an appendix.The following new synonymies are proposed: Cyclonotum Dejean, 1833 (= Dactylosternum Wollaston, 1854) [Hydrophilidae], Hyporhiza Dejean, 1833 (= Rhinaspis Perty, 1830) [Scarabaeidae], Aethales Dejean, 1834 (= Epitragus Latreille, 1802) [Tenebrionidae], Arctylus Dejean, 1834 (= Praocis Eschscholtz, 1829) [Tenebrionidae], Euphron Dejean, 1834 (= Derosphaerus Thomson, 1858) [Tenebrionidae], Hipomelus Dejean, 1834 (= Trachynotus Latreille, 1828) [Tenebrionidae], Pezodontus Dejean, 1834 (= Odontopezus Alluaud, 1889) [Tenebrionidae], Zygocera Dejean, 1835 (= Disternopsis Breuning, 1939) [Cerambycidae], and Physonota Chevrolat, 1836 (= Anacassis Spaeth, 1913) [Chrysomelidae].

In order to evaluate the diversity of Central European Myriapoda species in the course of the German Barcode of Life project, 61 cytochrome c oxidase I sequences of the genus Cryptops Leach, 1815, a centipede genus of the order Scolopendromorpha, were successfully sequenced and analyzed. One sequence of Scolopendra
cingulata Latreille, 1829 and one of Theatops
erythrocephalus Koch, 1847 were utilized as outgroups. Instead of the expected three species (Cryptops
parisi Brolemann, 1920; Cryptops
anomalans Newport, 1844; Cryptops
hortensis (Donovan, 1810)), analyzed samples included eight to ten species. Of the eight clearly distinguishable morphospecies of Cryptops, five (Cryptops
parisi; Cryptops
croaticus Verhoeff, 1931; Cryptops
anomalans; Cryptops
umbricus Verhoeff, 1931; Cryptops
hortensis) could be tentatively determined to species level, while a further three remain undetermined (one each from Germany, Austria and Croatia, and Slovenia). Cryptops
croaticus is recorded for the first time from Austria. A single specimen (previously suspected as being Cryptops
anomalans), was redetermined as Cryptops
umbricus Verhoeff, 1931, a first record for Germany. All analyzed Cryptops species are monophyletic and show large genetic distances from one another (p-distances of 13.7–22.2%). Clear barcoding gaps are present in lineages represented by >10 specimens, highlighting the usefulness of the barcoding method for evaluating species diversity in centipedes. German specimens formally assigned to Cryptops
parisi are divided into three clades differing by 8.4–11.3% from one another; their intra-lineage genetic distance is much lower at 0–1.1%. The three clades are geographically separate, indicating that they might represent distinct species. Aside from Cryptops
parisi, intraspecific distances of Cryptops spp. in Central Europe are low (<3.3%). 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

All known taxa of the genus Endothyrella Zilch, 1960 (family Plectopylidae) are reviewed. Altogether 23 Endothyrella species are recognized. All species are illustrated and whenever possible, photographs of the available type specimens are provided. Five new species are described: Endothyrella
angulata Budha & Páll-Gergely, sp. n., Endothyrella
dolakhaensis Budha & Páll-Gergely, sp. n. and Endothyrella
nepalica Budha & Páll-Gergely, sp. n. from Nepal, Endothyrella
robustistriata Páll-Gergely, sp. n. from the Naga Hills, India, and Endothyrella
inexpectata Páll-Gergely, sp. n. from Sichuan, China. Helix (Plectopylis) munipurensis Godwin-Austen, 1875 is synonymized with Helix (Plectopylis) serica Godwin-Austen, 1875, and Plectopylis (Endothyra) gregorsoni Gude, 1915 is synonymized with Helix (Plectopylis) macromphalus W. Blanford, 1870. Plectopylis
plectostoma
var.
exerta Gude, 1901 is a synonym of Plectopylis
plectostoma
var.
tricarinata Gude, 1896, which is a species in its own right. Five species of the genus Chersaecia viz. Plectopylis (Chersaecia) bedfordi Gude, 1915, Helix (Plectopylis) brahma Godwin-Austen, 1879, Helix (Plectopylis) Oglei Godwin-Austen, 1879, Helix (Plectopylis) serica Godwin-Austen, 1875, and Plectopylis (Endothyra) williamsoni Gude, 1915 are moved to Endothyrella. The holotype of Plectopylis
hanleyi Godwin-Austen, 1879 seems to be lost; therefore, Plectopylis
hanleyi is considered to be a nomen dubium. 相似文献
