RESUMO

The Nearctic shield-back katydid genus Neduba is revised. Species boundaries were demarcated by molecular phylogenetic analysis, morphology, quantitative analysis of calling songs, and karyotypes. Nine previously described species are redescribed: N. carinata, N. castanea, N. convexa, N. diabolica, N. extincta, N. macneilli, N. propsti, N. sierranus, and N. steindachneri, and twelve new species are described: N. ambagiosa sp. n., N. arborea sp. n., N. cascadia sp. n., N. duplocantans sp. n., N. inversa sp. n., N. longiplutea sp. n., N. lucubrata sp. n., N. oblongata sp. n., N. prorocantans sp. n., N. radicata sp. n., N. radocantans sp. n., and N. sequoia sp. n. We chose a lectotype for N. steindachneri and transferred N. picturata from a junior synonym of N. diabolica to a junior synonym of N. steindachneri. Diversification in this relict group reflects cycles of allopatric isolation and secondary contact amidst the tumultuous, evolving geography of western North America. The taxonomy and phylogenies presented in this revision lay the groundwork for studies of speciation, biogeography, hybrid zones, and behavioral evolution. Given that one Neduba species is already extinct from human environmental disturbance, we suggest conservation priorities for the genus.

RESUMO

The New World Jerusalem crickets currently consist of 4 genera: Stenopelmatus Burmeister, 1838, with 33 named entities; Ammopelmatus Tinkham, 1965, with 2 described species; Viscainopelmatus Tinkham, 1970, with 1 described species, and Stenopelmatopterus Gorochov, 1988, with 3 described species. We redefine the generic boundaries of these 4 genera, synonymize Stenopelmatopterus under Stenopelmatus, and synonymize Viscainopelmatus under Ammopelmatus. We then discuss, and illustrate, all the types of the species of Stenopelmatus, all of which only occur south of the United States' border.                We recognize as valid the following 5 described Mexican and Central American species: S. ater, S. piceiventris, S. sartorianus, S. talpa, and S. typhlops. We declare the following 13 described Mexican and Central American Stenopelmatus taxa as nomen dubium: S. calcaratus, S. erythromelus, S. guatemalae, S. histrio, S. lessonae, S. lycosoides, S. mexicanus, S. minor, S. nieti, S. sallei, S. sumichrasti, S. toltecus, and S. vicinus. We designate a neotype for S. talpa and lectotypes for S. ater, S. guatemalae, S. histrio, S. lessonae, S. mexicanus, S. minor, S. nieti, S. sallei, S. sumichrasti, and S. toltecus. We assign a type locality for S. piceiventris. We concur with the previous synonymy of S. politus under S. sartorianus. We describe 14 new species of Stenopelmatus from Mexico, Honduras and Ecuador, based on a combination of adult morphology, DNA, calling song drumming pattern, distribution, and karyotype: S. chiapas sp. nov., S. cusuco sp. nov., S. diezmilpies sp. nov., S. durango sp. nov., S. ecuadorensis sp. nov., S. faulkneri sp. nov., S. honduras sp. nov., S. hondurasito sp. nov., S. mineraldelmonte sp. nov., S. nuevoleon sp. nov., S. perote sp. nov., S. saltillo sp. nov., S. sanfelipe sp. nov., and S. zimapan sp. nov.                  We transfer the following 16 described United States taxa, plus S. cephalotes from the "west coast of North America", from Stenopelmatus to Ammopelmatus: A. cahuilaensis, A. californicus, A. cephalotes, A. fasciatus, A. fuscus, A. hydrocephalus, A. intermedius, A. irregularis, A. longispinus, A. mescaleroensis, A. monahansensis, A. navajo, A. nigrocapitatus, A. oculatus, A. pictus, and A. terrenus, along with the Mexican taxon A. comanchus: these species will be discussed in a subsequent paper (Weissman et al. in prep).                We believe that all new Jerusalem cricket species descriptions should include, at a minimum, calling drum (most important) and DNA information.

RESUMO

BACKGROUND: Amino acid substitution models play an important role in inferring phylogenies from proteins. Although different amino acid substitution models have been proposed, only a few were estimated from mitochondrial protein sequences for specific taxa such as the mtArt model for Arthropoda. The increasing of mitochondrial genome data from broad Orthoptera taxa provides an opportunity to estimate the Orthoptera-specific mitochondrial amino acid empirical model. RESULTS: We sequenced complete mitochondrial genomes of 54 Orthoptera species, and estimated an amino acid substitution model (named mtOrt) by maximum likelihood method based on the 283 complete mitochondrial genomes available currently. The results indicated that there are obvious differences between mtOrt and the existing models, and the new model can better fit the Orthoptera mitochondrial protein datasets. Moreover, topologies of trees constructed using mtOrt and existing models are frequently different. MtOrt does indeed have an impact on likelihood improvement as well as tree topologies. The comparisons between the topologies of trees constructed using mtOrt and existing models show that the new model outperforms the existing models in inferring phylogenies from Orthoptera mitochondrial protein data. CONCLUSIONS: The new mitochondrial amino acid substitution model of Orthoptera shows obvious differences from the existing models, and outperforms the existing models in inferring phylogenies from Orthoptera mitochondrial protein sequences.

RESUMO

Orthoptera is the most diverse order of polyneopterans, and the forewing and hindwing of its members exhibit extremely variability from full length to complete loss in many groups; thus, this order provides a good model for studying the effects of insect flight ability on the evolutionary constraints on and evolutionary rate of the mitochondrial genome. Based on a data set of mitochondrial genomes from 171 species, including 43 newly determined, we reconstructed Orthoptera phylogenetic relationships and estimated the divergence times of this group. The results supported Caelifera and Ensifera as two monophyletic groups, and revealed that Orthoptera originated in the Carboniferous (298.997 Mya). The date of divergence between the suborders Caelifera and Ensifera was 255.705 Mya, in the late Permian. The major lineages of Acrididae seemed to have radiated in the Cenozoic, and the six patterns of rearrangement of 171 Orthoptera mitogenomes mostly occurred in the Cretaceous and Cenozoic. Based on phylogenetic relationships and ancestral state reconstruction, we analysed the evolutionary selection pressure on and evolutionary rate of mitochondrial protein-coding genes (mPCGs). The results indicated that during approximately 300 Mya of evolution, these genes experienced purifying selection to maintain their function. Flightless orthopteran insects accumulated more non-synonymous mutations than flying species and experienced more relaxed evolutionary constraints. The different wing types had different evolutionary rates, and the mean evolutionary rate of Orthoptera mitochondrial mPCGs was 13.554 × 10-9 subs/s/y. The differences in selection pressures and evolutionary rates observed between the mitochondrial genomes suggested that functional constraints due to locomotion play an important role in the evolution of mitochondrial DNA in orthopteran insects with different wing types.

RESUMO

Recently, the heteroxenous eyeworm, Oxyspirura petrowi, has gained attention due to its prevalence in the declining game bird, Northern bobwhite (Colinus virginianus), but the intermediate hosts of many nematodes remain unknown. However, identifying the intermediate host of O. petrowi with traditional techniques would be difficult and time-consuming, especially considering there are more than 80 potential orthopteran hosts just in Texas. To screen a large number of samples quickly and effectively, primers for nested PCR (nPCR) were developed using the internal transcribed spacer 1 (ITS1) region. Then the nPCR was used to identify which of the 35 species collected from the Order Orthoptera were potential intermediate hosts of O. petrowi. With this technique, 18 potential intermediate hosts were identified. Later, we collected live specimens of species that tested positive to confirm the presence of larvae, but larvae were not found in the live specimens, nor in the extra tissue of the species that had tested positive for O. petrowi DNA. Despite this, this study demonstrated that nPCR is more sensitive than traditional techniques and can be a valuable tool in determining the intermediate hosts of parasites.

RESUMO

The repeated evolutionary specialization of distantly related insects to cardenolide-containing host plants provides a stunning example of parallel adaptation. Hundreds of herbivorous insect species have independently evolved insensitivity to cardenolides, which are potent inhibitors of the alpha-subunit of Na+,K+-ATPase (ATPα). Previous studies investigating ATPα-mediated cardenolide insensitivity in five insect orders have revealed remarkably high levels of parallelism in the evolution of this trait, including the frequent occurrence of parallel amino acid substitutions at two sites and recurrent episodes of duplication followed by neo-functionalization. Here we add data for a sixth insect order, Orthoptera, which includes an ancient group of highly aposematic cardenolide-sequestering grasshoppers in the family Pyrgomorphidae. We find that Orthopterans exhibit largely predictable patterns of evolution of insensitivity established by sampling other insect orders. Taken together the data lend further support to the proposal that negative pleiotropic constraints are a key determinant in the evolution of cardenolide insensitivity in insects. Furthermore, analysis of our expanded taxonomic survey implicates positive selection acting on site 111 of cardenolide-sequestering species with a single-copy of ATPα, and sites 115, 118 and 122 in lineages with neo-functionalized duplicate copies, all of which are sites of frequent parallel amino acid substitution. This article is part of the theme issue 'Convergent evolution in the genomics era: new insights and directions'.

RESUMO

We investigated the molecular phylogenetic divergence and historical biogeography of cave crickets belonging to the family Rhaphidophoridae (Orthoptera, Ensifera). We used taxa representative of most of the regions embraced by the family, considering samples of Macropathinae from Gondwana land (i.e., Tasmania, Australia, New Zealand, South Africa, and South America); Aemodogryllinae and Rhaphidophorinae from Southern-eastern Asia (i.e., India, Bhutan, China, Philippines and the Sulawesi islands); Dolichopodainae and Troglophilinae from the Mediterranean region and Ceuthophilinae from North America. Based on previous papers, we carried out an analysis of both mitochondrial and nuclear DNA sequences considering the ribosomal RNA units 12S, 16S, 18S, and 28S. To reconstruct phylogeny, we use cladistics, Maximum Likelihood (ML), and Bayesian analyses. All phylogenetic analyses showed the same highly supported topology generally congruent with the classical systematic arrangement at the level of each sub-family but strongly disagree with previous affinity hypotheses between sub-families based on morphological characters. Our results reveal a close affinity between Asiatic and Gondwanian taxa from one hand and between North American and Mediterranean ones from the other hand. Dating estimates indicated that Rhaphidophoridae originated in the Cretaceous period during the Mesozoic era with the ancestral area located both in the northern and southern hemisphere. A possible biogeographic scenario, reconstructed using S-DEC with RASP software, suggested that the current distribution of Rhaphidophoridae might be explained by a combination of both dispersal and vicariance events occurred especially in the ancestral populations. The radiation of Rhaphidophoridae started within the Pangaea, where the ancestor of Rhaphidophoridae occurred throughout an ancestral area including Australia, North America, and the Mediterranean region. The opening of the Atlantic Ocean promoted the divergence of North American and Mediterranean lineages while the differentiation of the southern lineages, spread from Australia, appears to be related to the fragmentation of Gondwana land.

RESUMO

BACKGROUND: DNA barcoding has been developed as a useful tool for species discrimination. Several sequence-based species delimitation methods, such as Barcode Index Number (BIN), REfined Single Linkage (RESL), Automatic Barcode Gap Discovery (ABGD), a Java program uses an explicit, determinate algorithm to define Molecular Operational Taxonomic Unit (jMOTU), Generalized Mixed Yule Coalescent (GMYC), and Bayesian implementation of the Poisson Tree Processes model (bPTP), were used. Our aim was to estimate Chinese katydid biodiversity using standard DNA barcode cytochrome c oxidase subunit I (COI-5P) sequences. RESULTS: Detection of a barcoding gap by similarity-based analyses and clustering-base analyses indicated that 131 identified morphological species (morphospecies) were assigned to 196 BINs and were divided into four categories: (i) MATCH (83/131 = 64.89%), morphospecies were a perfect match between morphospecies and BINs (including 61 concordant BINs and 22 singleton BINs); (ii) MERGE (14/131 = 10.69%), morphospecies shared its unique BIN with other species; (iii) SPLIT (33/131 = 25.19%, when 22 singleton species were excluded, it rose to 33/109 = 30.28%), morphospecies were placed in more than one BIN; (iv) MIXTURE (4/131 = 5.34%), morphospecies showed a more complex partition involving both a merge and a split. Neighbor-joining (NJ) analyses showed that nearly all BINs and most morphospecies formed monophyletic cluster with little variation. The molecular operational taxonomic units (MOTUs) were defined considering only the more inclusive clades found by at least four of seven species delimitation methods. Our results robustly supported 61 of 109 (55.96%) morphospecies represented by more than one specimen, 159 of 213 (74.65%) concordant BINs, and 3 of 8 (37.5%) discordant BINs. CONCLUSIONS: Molecular species delimitation analyses generated a larger number of MOTUs compared with morphospecies. If these MOTU splits are proven to be true, Chinese katydids probably contain a seemingly large proportion of cryptic/undescribed taxa. Future amplification of additional molecular markers, particularly from the nuclear DNA, may be especially useful for specimens that were identified here as problematic taxa.

RESUMO

Species of Temnomastax have wide morphological similarities, and differentiation is usually based on male and female genitalia. In this study, we tested whether morphometric differences contribute to differentiation of species of Temnomastax, proposed an identification key for males, and morphometrically studied the sexual dimorphism of Temnomastax hamus and Temnomastax ricardoi. Analysis was performed using 204 specimens belonging to six species; fifteen morphometric variables were used. We used MANOVA and ANOVA to test the morphometric differences among species and Discriminant Analysis for sexual distinction. Temnomastax sp. nov. 1 had the highest values in ⅓ of all analyzed variables used for morphometric distinction of males, followed by Temnomastax latens, T. ricardoi and Temnomastax sp. nov. 2, and T. hamus and Temnomastax tigris. Two groups were formed by the MANOVA, with length of body, length of hind femur, and length of tegmen as the main variables that distinguished them. Overall, females of T. hamus and T. ricardoi presented higher averages for measurement values used in morphometric distinction between sexes than conspecific males and based on discriminant analysis we found significant differences between sexes. There are significant differences in morphometric variations and the ratio between body length and tegmen length provided reliable evidence for differentiation among species, which can be used as a valid tool that complements the identification of Temnomastax species.

RESUMO

In the present study, eggs of eight species of the Tettigonoidea superfamily have been examined with the aim to find characteristic traits of each of the studied taxa. In addition, we aim to distinguish them through their eggshell morphology, a technique that nowadays is known as ootaxonomy. All the eggs analysed belong to four subfamilies of the Tettigoniidae family (Bradyporinae: Ephippiger diurnus cunii, Parasteropleurus perezii, Lluciapomaresius panteli, L. ortegai, Tettigoniinae: Decticus verrucivorus, Antaxius hispanicus, and Meconematinae: Cyrtaspis scutata) and from family Phaneropteridae: Phaneroptera nana. Observations and comparisons were made after optical and Scanning Electron Microscope (SEM) photographs. In all katydids evaluated, we observed that hexagonal cells usually compose the chorion, nevertheless, in some cases egg surfaces appearance is follicular or smooth. Micropylar areas are different among the species examined. Ootaxonomy allowed us to differentiate between the genera studied and the two more related species: Lluciapomaresius panteli and L. ortegai.

RESUMO

Although mitogenomes are useful tools for inferring evolutionary history, only a few representative ones can be used for most Ensifera lineages. Thirty-two ensiferan mitogenomes were determined using ABI Sanger sequencing and standard primer walking of 2-3 overlapping Long-PCR fragments, or Illumina® HiSeq2000 for "shotgun" sequenced long-PCR-amplified mitochondrial or total genomic DNA. Six patterns of gene arrangements, including the novel trnR-trnSAGN-trnA-trnN-trnG-nad3 in Lipotactes tripyrga (Lipotactinae), were identified from 59 ensiferan mitogenomes. The results suggest that trnM-trnI-trnQ and trnA-trnR-trnE-trnSAGN-trnN-trnF rearrangements might be a shared derived character in Pseudophyllinae and Gryllidae, respectively. We found base composition biases in our dataset, which potentially complicate the inference of higher-level ensiferan phylogeny. Site-heterogeneous Bayesian inference (BI) and site-homogeneous maximum likelihood (ML) analyses recovered all ensiferan superfamilies as monophyletic. The site-homogeneous BI analysis failed to recover the monophyly of Stenopelmatoidea. As Schizodactyloidea was only represented by Comicus campestris, its monophyly could not be tested. In the Triassic/Jurassic boundary, Ensifera diverged into grylloid and non-grylloid clades. All analyses confirmed Grylloidea and Gryllotalpoidea as sister groups. Site-heterogeneous BI analysis found Schizodactyloidea as the most basal lineage and sister to the clade formed by Grylloidea and Gryllotalpoidea, but the site-homogeneous analyses placed it basally to the non-grylloid clade and recovered a sister relationship between Tettigonioidea and (Hagloidea, Rhaphidophoroidea, Stenopelmatoidea), although this clade had a low support. The site-heterogeneous BI analysis found Tettigonioidea and Hagloidea were sister groups (posterior probability (PP)=0.99), Stenopelmatoidea was sister to (Tettigonioidea, Hagloidea) (PP>0.91), and Rhaphidophoroidea was basal to the non-grylloid clade. At a lower level, all analyses divided Tettigonioidea into Phaneropteridae and Tettigoniidae.

RESUMO

Temnomastax spielmanni Olivier, 2014 n. syn. is proposed as new synonym of Eumastacops nemorivaga Rehn & Rehn, 1942. New distribution records in Peru and Colombia are provided for the following four species: Eumastax nigrovittata Descamps, 1979; Paramastax nigra (Scudder, 1875); Pseudomastax nigroplagiata Descamps, 1970; and Pseudomastax personata (Bolívar, 1881). New information on the distribution of Paramastax flavovittata Descamps, 1973 and E. nemorivaga is added, resulting in the expansion of the geographic distribution. Photographs of all studied species are provided.

RESUMO

We present a DNA barcoding study on the insect order Orthoptera that was generated in collaboration between four barcoding projects in three countries, viz. Barcoding Fauna Bavarica (Germany), German Barcode of Life, Austrian Barcode of Life and Swiss Barcode of Life. Our data set includes 748 COI sequences from 127 of the 162 taxa (78.4%) recorded in the three countries involved. Ninety-three of these 122 species (76.2%, including all Ensifera) can be reliably identified using DNA barcodes. The remaining 26 caeliferan species (families Acrididae and Tetrigidae) form ten clusters that share barcodes among up to five species, in three cases even across different genera, and in six cases even sharing individual barcodes. We discuss incomplete lineage sorting and hybridization as most likely causes of this phenomenon, as the species concerned are phylogenetically young and hybridization has been previously observed. We also highlight the problem of nuclear mitochondrial pseudogenes (numts), a known problem in the barcoding of orthopteran species, and the possibility of Wolbachia infections. Finally, we discuss the possible taxonomic implications of our barcoding results and point out future research directions.

RESUMO

Tridactylus galla was described by Henri de Saussure (1895) on the basis of a single adult female collected during Vittorio Bottego's first expedition to the Horn of Africa in 1892 and 1893. The species appears in lists compiled by Fenizia (1896), Lucas (1898) and Kirby (1906), but aside from a brief mention by Günther (1995), is entirely overlooked by subsequent authors and is absent from Otte's (1997) catalogue. During the course of compiling an annotated catalogue of the Orthoptera described by Saussure (Hollier and Heads, 2012) we were able to relocate the type of Tridactylus galla in the collection of the Museo Civico di Storia Naturale "Giacomo Doria" in Genova, Italy. Our examination of the specimen confirmed Günther's (1995) assertion that its placement in Tridactylus Olivier, 1789 is erroneous, and the species is herein formally transferred to the genus Xya Latreille, 1809.

RESUMO

An annotated checklist of 51 Orthoptera taxa (Tettigonioidea, Pyrgomorphoidea and Acridoidea) of Kafa Biosphere Reserve, Bale Mountains National Park and some additional sites in Ethiopia is presented. Ten species are newly recorded for the country. Four species are new to science: Peropyrrhicia attilioi n. sp., P. keffensis n. sp., P. semiensis n. sp. and Coryphosima danieli n. sp. The status of Peropyrrhicia cooperi Uvarov, 1934 and P. scotti Uvarov, 1934 is revised: both are considered valid species.

RESUMO

The tribe of the giant katydids Steirodontini is reviewed, its relationship with other groups of Phaneropterinae from the Old and New World is discussed, and an updated key to genera is presented. Nicklephyllum n. gen. is established to accommodate one species described as Stilpnochlora acanthonotum Nickle, 1985 from Colombia. Cnemidophyllum tani n. sp. from the Colombian Amazon is described. Another new combination and two synonymies are proposed: Steirodon (Frontinus) emsleyi (Piza, 1979) n. comb., Steirodon (Posidippus) parastahli Piza, 1979 n. syn. (of Steirodon (Steirodon) ponderosum Stål, 1873), and Steirodon (Posidippus) tricenarius (Piza, 1974) n. syn. (of Steirodon (Frontinus) rufolineatum Emsley, 1970). Finally, Steirodon (Posidippus) rarospinulosum (Brunner von Wattenwyl, 1891), only known from Peru, is reported from the Colombian Amazon.
