“…Closed-forest areas are important in several ways for the studied scorpion species. Ananteris mauryi is a small species (20-25 mm) considered humicolous because it depends on places with high humidity, such as the lower layers of litter, to establish its populations (Lourenc ßo 1982;Lira et al 2013). Tityus pusillus is a scorpion that, despite being found in Caatinga vegetation, is sensitive to environmental changes such as those caused by habitat fragmentation Dionisio-da-Silva et al 2018).…”

Current predictions about the responses of species to climate change strongly rely on projecting altered environmental conditions on their distributions. In this study, we investigated the effects of future climate change scenarios on the potential distribution of 10 species of scorpions in north‐eastern Brazil in the context of their degree of specialisation to closed (Atlantic and Amazon Forests) and open (Caatinga and Cerrado) habitats. Scorpion species were classified as habitat specialists or generalists according to the IndVal index, and present and future species distribution models were prepared using minimum volume ellipsoids. According to IndVal, four species were classified as closed‐forest specialists (Ananteris mauryi, Tityus brazilae, Tityus pusillus and Tityus neglectus), four as open‐forest specialists (Jaguajir agamemnon, Jaguajir rochae, Physoctonus debilis and Bothriurus rochai), and two as generalists (Tityus stigmurus and Bothriurus asper). All species presented a drastic reduction in potential distribution, ranging from 44% to 72%, when compared with their current distribution. In addition, we found a reduction in scorpion species richness under future climate change scenarios. This finding has implications for scorpion conservation. Further, the results show that climate change may impact the composition of scorpion assemblages in north‐eastern Brazil, revealing important implications for human–scorpion interactions.

ABSTRACT. Checklist of the scorpions (Arachnida, Scorpiones) from Mato Grosso do Sul State, Brazil. In this paper it is provided a checklist of Scorpiones species in the state of Mato Grosso do Sul, Brazil. There are 16 species and one non-nominotypical subspecies recorded for the state, although it is discussed the presence and/or the taxonomic status of three of these species. This, it is considered that the scorpiofauna of the Mato Grosso do Sul is actually composed of 13 species, which represents more than 50% of all known species from Central-western Brazil. Two bothriurid species are known only for this state and are considered endemics: Bothriurus pora

“…Publications on some species of Tityus describe that accidents occur in regions where high numbers of scorpions can be found in a city [31,63,64,65] through its adaptation to urban environment [18,19,20,26,66,67,68,] or in determinate regions of a country [19,20,26,68,69,70,71,72,73], and accidents in some Brazilian cities could be associated with old constructions [74,75] and in addition postulate the expansion from nuclei in the cities [76]. Although up to date, we have no data to demonstrate the relationship between density of scorpions and accidents, most of these characteristics are shared by Tityus trivittatus in Buenos Aires city.…”

Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed.
