DE ROODT, Adolfo R et al. Expansion of the distribution of scorpions of the genus Tityus C. L. Koch 1836 in Argentina: Implications in public health. Acta toxicol. argent. [online]. 2019, vol.27, n.3, pp.109-119. ISSN 1851-3743.

Several species of Tityus have been described in regions of Argentina where their presence had not been previously described. These are: 1- Tityus bahiensis in the provinces of Entre Ríos and Buenos Aires (in the localities of Lanús and San Clemente del Tuyú), and 2- Tityus confluens in the city of Buenos Aires and in the province of Buenos Aires in the localities of Pilar, La Plata, Mar del Plata and Bahía Blanca. These findings modify the distribution map of scorpions of sanitary importance in Argentina, reason for which this new distribution must be considered when facing a scorpion sting. This is especially important in the city of Buenos Aires and the province of Buenos Aires, where most of the accidents by scorpions are caused by Tityus trivittatus, and where at least in some of their regions, T. confluens or T. bahiensis can be found at present. The possible reasons of this new distribution, as well as the possible causes for the occurrence of severe envenomations in regions where these were not observed historically, are discussed. Based on the severe envenomations observed and on this new distribution map, emphasis is placed on the need to capacitate health personnel in general and intensivists or critical care physicians in particular to adequately treat scorpion accidents.
