“…Fourteen biogeographical provinces, regions containing high levels of biodiversity and endemism, are currently recognized as part of the Andes in the South American transition zone and the Andean region sensu Morrone (, ). Andean uplift was suggested as a driver of diversification in taxa such as the angiosperm genera Heliotropium L. (Luebert et al ., ) and Hedyosmum Sw. (Antonelli & Sanmartín, ), scorpions (Mattoni et al ., ), grasshoppers (Pocco et al ., ), glassfrogs (Hutter et al ., ), and brush‐finches (Sanchez‐Gonzalez et al ., ). Furthermore, Andean orogeny caused the separation of habitats and subsequent speciation of their respective faunas, especially in freshwater fishes (Albert et al ., ).…”

Aim One of the planet's most imposing geomorphological features, the Andes, played an important role in the evolution of South America's flora and fauna. The bothriurid scorpion genus Brachistosternus Pocock, 1893 comprises more than 40 species with high diversity and endemism in the Andes. The present contribution investigates the biogeographical history of this genus using molecular phylogenetics and dating, to determine the role of Andean uplift on the distribution and diversification of its species. Location South America. Methods A dated species tree was obtained for 55 putative species based on two nuclear and three mitochondrial gene loci. Ancestral ranges and biogeographical events were estimated on the species tree, diversification rates and rate shifts calculated, and areas with high phylogenetic diversity (PD) and evolutionary distinctiveness identified. Results Brachistosternus diversified at a steady rate during the main Andean uplift. The central Andean and western slope/Pacific coastal biogeographical provinces played important roles as ancestral areas. Coastal areas of central Chile and southern Peru exhibit high levels of PD in Brachistosternus, suggesting they experienced a relatively long period of ecological stability, while the Andes continued to rise. Main conclusions Andean uplift created new habitats and climate regimes, favouring speciation in genera such as Brachistosternus. Coastal areas to the west of the Andes continued to harbour older lineages while accommodating more recently diverged lineages from the nearby Andes.

“…All species, except P. virescens, have a very restricted distribution, which could be an indicator of a probable widespread ancestor with broader distribution and speciation may have occurred due to the isolation of species on each mountain. There are other mountain melanoplines with similar patterns in genera, such as Jivarus (Cigliano and Amédégnato, 2010), Melanoplus (Knowles and Massatti, 2017), Orotettix (Scattolini et al 2018), and Ponderacris (Pocco et al 2013) among others. Mastretta-Yanes et al (2015) analyzed high-elevation taxa in the TransMexican Volcanic Belt and found that these taxa have been exposed to a sky-island dynamic due to climate variations.…”

Zootaxa 4459 (3): 551-564 Abstract A new species of Melanoplinae (Orthoptera: Acrididae) is described from Central Mexico: Pedies andreae sp. nov. Fontana, Mariño-Pérez, & Woller and is added to the 12 existing species. Taxonomic placement of this species is justified based on distinct morphology and comparisons with congeneric species are provided. Additionally, species in this genus are associated with higher elevations (1,700 to 3,700 masl) that possess larger fluctuations in temperatures. We observed that females of P. andreae sp. nov. exhibit blue coloration on their abdomens and we discuss the possible reasons for this peculiar pigmentation. Interestingly, we did not observe this coloration in males. Finally, images are provided for three live previously described species of Pedies.

“…Even though the Chaco biome has been surveyed by outstanding acridiologists (Liebermann J., Carbonell C.S., Ronderos R.A., among others) rendering a significant knowledge of its acridiofauna, at least for some groups such as romaleids, it seems that there are still undiscovered species in the region. We emphasize the importance of systematic surveys of this highly diversified biome of South America that may not only render the discovery of new species, but also contribute to a better knowledge of species richness and endemism, as a path leading to improved conservation strategies (Pocco et al ., ).…”

The open vegetation biomes, within the limits of the Chacoan subregion, occur along a diagonal in eastern South America covering a large range of environmental conditions. In order to contribute to the knowledge on the biodiversity of these open biomes, we analysed the phylogenetic relationships of the grasshopper genus Zoniopoda to the remaining South American Romaleinae, and examined the biogeographical patterns of diversification of the genus. The study is based on morphological and molecular (COI and H3) evidence, including 12 species of Zoniopoda and 17 species of four tribes of South American Romaleinae. We describe a new species of Zoniopoda, and test its taxonomic placement within the group. Results of our phylogenetic analyses recovered Zoniopoda as a monophyletic group with high support values. According to the dispersion-vicariance analysis, the ancestor of Zoniopoda may have been distributed in an area corresponding to the Chacoan and Cerrado provinces. A vicariant event, that could be explained by the uplift of the Brazilian Plateau and the subsidence of the Chaco, is hypothesized to have occurred splitting the ancestral distribution of Zoniopoda, resulting in the independent evolution of the Tarsata group within the Cerrado and the Iheringi group in the Chacoan subregion.This published work has been registered in ZooBank, http://zoobank.org/urn:lsid: zoobank.org:act:FCFB4C5D-1741-46F1-8E25-B37ED2B9D872.Correspondence: Martina E.
