“…Extraction and amplification of two mitochondrial gene fragments [NADH dehydrogenase subunit 2 (ND2) and cytochrome c oxidase subunit I (COI)] and one nuclear gene fragment [histone 3 (H3)] were performed using the methods of Husemann et al (2013). Previous studies have demonstrated that these markers are useful for comparisons among grasshopper species (Husemann et al, 2013;Guzman et al, 2017;Pocco et al, 2018;Scattolini et al, 2018). Sequences for the three gene regions were examined, trimmed and aligned using Geneious 6.1.6 (http:// www.geneious.com; Kearse et al, 2012)).…”

A biogeographical study of the genus group Scotussae, a clade of grasshoppers endemic to the subtropical temperate region of the La Plata Basin, South America, was performed within a phylogenetic context to test whether wing reduction reflects evolutionary and ecological processes within the clade. We used an integrative biogeographical approach to determine the role of geohistorical events, geography, ecology and phylogenetic niche conservatism on the distribution and diversification processes of the group. We performed a total evidence phylogenetic analysis and tested the phylogenetic signal of ecological niche traits (niche optimum and niche breadth). We also assessed the degree to which phylogenetic distance is correlated with geographical and ecological niche traits and we used BioGeoBEARS to estimate ancestral ranges. The results provided evidence for phylogenetic niche conservatism as well as a significant association between phylogeny and both geographical and, more strongly, ecological traits. Two main clades were clearly associated with wing development, and evidence points to the evolutionary and ecological processes within these two groups being different. The Brachypterous clade shows evidence that allopatric speciation was the main source of diversification, while for the Macropterous clade sympatric speciation seems more likely.

New Species and Conservation Status of the Genus Group Scotussae (Orthoptera: Acrididae) in the Atlantic Forest

Two new brachypterous species of the genus Scotussa, with restricted distributions, are described for one of the most important and greatly threatened biodiversity hotspots, the Atlantic Forest. These species belong to the genus group Scotussae, a diverse group regarding mobility and oviposition habits. It has been mentioned that these characteristics could lead to restrictions in the species distribution. Based on these antecedents and considering the importance of biodiversity conservation within the Atlantic Forest, we performed novel conservation indices for this group. The rapid assessment indices calculated herein are based upon Red List status, endemism, dispersal capacity, and life-history traits that allowed us to identify areas for conservation for this group of grasshoppers. For a better understanding of the conservation status of the group, the results of the indices were compared with protected areas and Key Biodiversity Areas. Moreover, historical biome stability was also considered since it has been associated with different distributional and diversification patterns within the genus group Scotussae. The approach applied indicates that the indices recovered different but complementary information. The Grasshopper Biotic Index (GBI) determined important regions for conservation within the richest region of the group while the GBI/SiteScore located regions with lower diversity values for the group but with high importance regarding endemisms.

“…Pilgrim & Vondohlen (2008) studied the phylogenetic relationships of Sympetrinae based on molecular data (mitochondrial loci 16S and 12S rRNA) and morphological traits (38 wing venation characters); even though the study did not involve direct comparison of phylogenetic trees based on the two types of information, its conclusion was that the characteristics of the wing veins might be useless in the analysis of relationships due to homoplasy. However, morphological and genetic structure may undergo synchronous evolution in other insects, such as the pronotum and genital segments of grasshopper genus Zoniopoda (Pocco et al, 2018), and the wing veins and genital segments of Euptychiina butterflies (Marín et al, 2017), indicating that phylogenetic information may be contained in morphological features of some insects.…”

Background Establishing the species limits and resolving phylogenetic relationships are primary goals of taxonomists and evolutionary biologists. At present, a controversial question is about interspecific phylogenetic information in morphological features. Are the interspecific relationships established based on genetic information consistent with the traditional classification system? To address these problems, this study analyzed the wing shape structure of 10 species of Libellulidae, explored the relationship between wing shape and dragonfly behavior and living habits, and established an interspecific morphological relationship tree based on wing shape data. By analyzing the sequences of mitochondrial COI gene and the nuclear genes 18S, 28S rRNA and ITS in 10 species of dragonflies, the interspecific relationship was established. Method The wing shape information of the male forewings and hindwings was obtained by the geometric morphometrics method. The inter-species wing shape relationship was obtained by principal component analysis (PCA) in MorphoJ1.06 software. The inter-species wing shape relationship tree was obtained by cluster analysis (UPGMA) using Mesquite 3.2 software. The COI, 18S, ITS and 28S genes of 10 species dragonfly were blasted and processed by BioEdit v6 software. The Maximum Likelihood(ML) tree was established by raxmlGUI1.5b2 software. The Bayes inference (BI) tree was established by MrBayes 3.2.6 in Geneious software. Results The main difference in forewings among the 10 species of dragonfly was the apical, radial and discoidal regions dominated by the wing nodus. In contrast, the main difference among the hindwings was the apical and anal regions dominated by the wing nodus. The change in wing shape was closely related to the ability of dragonfly to migrate. The interspecific relationship based on molecular data showed that the species of Orthetrum genus branched independently of the other species. Compared to the molecular tree of 10 species, the wing shape clustering showed some phylogenetic information on the forewing shape (with large differences on the forewing shape tree vs. molecular tree), and there was no interspecific phylogenetic information of the hindwing shape tree vs. molecular tree. Conclusion The dragonfly wing shape characteristics are closely related to its migration ability. Species with strong ability to migrate have the forewing shape that is longer and narrower, and have larger anal region, whereas the species that prefer short-distance hovering or standing still for a long time have forewing that are wider and shorter, and the anal region is smaller. Integrating morphological and molecular data to evaluate the relationship among dragonfly species shows there is some interspecific phylogenetic information in the forewing shape and none in the hindwing shape. The forewing and hindwing of dragonflies exhibit an inconsistent pattern of morphological changes in different species.
