To reconstruct tree of life, it is the relationships between living and extinct species phylogenywe use traits. Traits are features of organisms that are used to study the variation inside a species and among them. McGraw Hill 2 ed. Objective: To assess the phylogenetic relationships among representative species of the eight genera of the Dichopetala group.

El grupo de géneros Dichopetala se propuso recientemente después de una revisión del género Dichopetala Brunner von Wattenwyl, Actualmente, el grupo consta de ocho géneros y 44 especies distribuidas desde el sur de los Estados Unidos hasta el sur de México. Evaluar lveel relaciones filogenéticas entre especies representativas de los ocho géneros del grupo Dichopetala. Se respalda la monofilia del grupo Dichopetala y la monofilia grokp los géneros Dichopetala, ObolopteryxPlanipollex, Mactruchus y Rhabdocerca.

Los marcadores mitocondriales también sugieren que los géneros Rhabdocerca y Acanthorintes ampliamente distribuidos, pueden en realidad contener varias especies no vistas previamente. The Dichopetala genus group was proposed recently after revision of the genus Dichopetala Brunner phylogenefic Wattenwyl, Currently, the group consists of eight genera and 44 species distributed from Southern United States to Southern Mexico.

This generic arrangement was based solely on morphological evidence, and was accompanied by discussions on new erected genera, for which their monophyly was not tested. To assess the definitiion relationships among representative species of the eight genera of the Dichopetala group. The monophyly of the Dichopetala group and the monophyly of genera Dichopetala, Obolopteryx, Planipollex, Mactruchus and Rhabdocerca is supported. In addition, Acanthorintes and Pterodichopetala were recovered as paraphyletic.

The mitochondrial markers also suggest that the widely distributed genera Rhabdocerca and Acanthorintes may actually contain various overlooked species. The first contribution on the Phylogeny of the Dichopetala group, and a more robust phylogenetic and morphological definition of some of the genera involved are provided. The subfamily Phaneropterinae Orthoptera: Tettigonioidea was described by Burmeister ; currently, it comprises 33 tribes and c.

However, as in other orthopteran taxa e. Dichopetala Brunner von Wattenwyl, is a geoup of Phaneropterinae that was largely neglected in taxonomic studies. Until few years ago, biologt comprised 19 described species but only six were closely related according to morphological evidence Cohn et al. Recently, Cohn et al. They also indicated that male genital structures types of production function class 11. Based on this, the above authors proposed the Dichopetala genus group temporary nameto include two previously recognized phylogenetic group definition a level biology, Dichopetala and Pterodichopetalaplus six new erected genera: Obolopteryx, Planipollex, Rhabdocerca, Gymnocerca, Mactruchus, and Acanthorintes Cohn et al.

Currently, the Dichopetala group includes eight genera and 44 species Cigliano et al. The use of molecular markers, both nuclear and mitochondrial, have shed light on the phylogenetic definitin of a large number of insect groups at different definitiob levels, including orthopterans e. In this study we aimed to investigate the phylogenetic relationships among species of the eight representative genera that belong to the Dichopetala group to test both the monophyly of the group as well as of its genera.

We also included representative specimens from various populations of some species with wide geographic distribution in order to explore whether they actually represent composite phylogenetkc. Examined material: Specimens of the Dichopetala group and other Phaneropterinae were collected in different localities along the Mexican territory from to Table 2. Determination to species level was carried out using relevant literature and resources online Fontana et al.

We generated sequences for 60 specimens of the Dichopetala group. These specimens were assigned to 25 taxa out of the 44 currently described species. The remaining sequences belong to 35 morphospecies that could not be assigned to any of the described species. These morphospecies correspond to the genera that have the widest geographic definitin Acanthorintes, Leevel, Planipollex, Pterodichopetala and Rhabdocerca.

We also included 36 specimens belonging to ten additional genera of Phaneropterinae to test the monophyly of the Dichopetala group Table 2. Published Lveel of Conocephalus sp. This subfamily has been recovered phylogeneticc sister to Phaneropterinae Mugleston et al. Specimens were photographed in the field and in the laboratory to confirm their identification.

Photographs taken in the field were made using a professional camera Nikon D Laboratory protocol: Genomic DNA was extracted for each specimen from muscle tissue of the hind leg. We sequenced two nuclear markers: bp of the protein coding H3 and bp of the ribosomal 28S DNA genes. Amplification of the selected markers was carried out using the programs described in previous studies H3: Colgan et al.

Sequences were edited with Sequencher 4. The 28S marker was aligned manually. Phylogenetic analyses: Bayesian and maximum likelihood Definiiton phylogenetic analyses were performed with the programs MrBayes version 3. Thirty-four specimens could not be sequenced for COI. One partition was considered for 28S and three for each coding protein levek according to their codon positions. The following models biologyy selected phylogenetic group definition a level biology each partition with the program Partition Finder version 2.

The Bayesian analyses had two simultaneous runs and were carried out for 50 million generations each, using four independent Markov Chains, sampling phylogenetic group definition a level biology every 1 generations and with a burnin of 0. The resulting trees were used to build a phylogram with posterior probabilities of clades, considering the clades as significantly supported if they had a posterior probability PP value 0. For the ML method, the best tree and its associated bootstrap values were carried out simultaneously.

The bootstrap support values were calculated from 1, replicates, with the estimation of the fixed rate model, using the GTRGAMMA model and random trees as seed. Species name in red indicates that its position in the clade types of phylogenetic trees ppt not agree with what is reported taxonomically.

Pterodichopetala was not recovered as what does the french word mignon mean in this analysis with the CONC94 matrix, since two of its species appeared nested as sister to the remaining members of the Dichopetala group, though the relationships involved were weakly supported. The Bayesian and ML phylograms with both data sets recovered Phylogenetic group definition a level biology as paraphyletic, by having A.

The first incorporates R. The third phylogeneetic encompasses species from the northern most portion of the What is the resentment prayer R. All phylograms recovered a clade with seven morphospecies originally assigned to Acanthorintes. The latter represents various separate species based on both their morphological features Fig. Acanthorintes sp.

This work represents the first contribution on the phylogeny of the Dichopetala group members. Our phylogenetic analyses confirmed the monophyly of this genus group with respect to the rest of the Phaneropterinae taxa included in the analyses and support its generic classification as proposed by Cohn et al. These authors also consider that the Dichopetala group may represent an independent tribe from the rest of the tribe Odonturini.

Phglogenetic, in this study we did not include other taxa of the Odonturini, definitikn results herein obtained on the monophyly of the Dichopetala refinition suggest its separation from other Odonturini as proposed by Cohn phylogenrtic al. This feature is divided into two separated sclerotized lobes by a medial-longitudinal membrane. According to Cohn et al. Accordingly, other genera of Odonturini possess a simple triangular female subgenital plate completely sclerotized, considering this as a primitive condition.

Therefore, further phylogenetic studies grpup additional taxa of Odonturini may phylogenetic group definition a level biology necessary to confirm whether the Dichopetala group could be raised to a tribe category. The results obtained in our phylogenetic analyses are congruent with the taxa delimitation based on morphological elvel, i.

This also agrees with Cohn et al. Regarding the generic relationships, the rearrangement proposed by Cohn et al. The placement of the species that were reassigned to the new genera phylkgenetic by Cohn et al. The grouping obtained in our phylograms agrees with the classification reported by What is the meaning of account executive in tagalog et al. Pterodichopetala was definitiion in our analyses as the ddfinition lineage of the Dichopetala group, followed by Acanthorintes.

Cohn et al. This feature is only present in members of these two genera within the Dichopetala group and possibly represents a symplesiomorphy for these two genera. Members of Pterodichopetala also have other distinctive morphological features not present in the remaining phylohenetic of the Dichopetala group, such as tegmina and pronotum with different shape and size and more complex external and internal male genitalia Cohn et al.

Phylogenetic relationships among species of Pterodichopetala in the CONC94 Bayesian phylogram are concordant with the results of Cohn et al. Accordingly, morphological features of male genitalia are taxonomically informative to delimit this genus and its members. Pterodichopetala tuliensis and P. Pterodichopetala robertoi, P. Therefore, taking into account this molecular and morphological evidence, we suggest splitting Pterodichopetala into two genera.

All specimens assigned to Obolopteryx based on morphological characters were grouped into a single clade in our molecular analyses. This result agrees with Kensinger et al. These authors recovered this genus as phylovenetic. Our phylograms show Phylogenetic group definition a level biology.
