Resumo

Scorpion envenomation is a growing public health concern in Brazil. The species Tityus confluens Borelli, 1899 has historically been overlooked as a major threat, although its recent presence in Parana<acute accent> raises new concerns. This study documents for the first time 30 epidemiological reports of T. confluens stings in Parana<acute accent>, primarily in Foz do Igua & ccedil;u (86.7 %) between 2012 and 2024. Most cases involved males (66.7 %), with victims exhibiting local symptoms such as pain (100 %), edema (60 %), and less commonly other manifestations as erythema and tingling (3.3 %). The most commonly stung body part were hands (15 reports, 50 %). No fatalities were recorded, and all cases were successfully managed with pain control measures, following national treatment guidelines. The presence of T. confluens in urban and rural areas, combined with taxonomic uncertainties and potential misidentifications in epidemiological databases, suggests the need for improved species identification and monitoring. Given to its synanthropic behavior, parthenogenetic reproduction, and reports of severe envenomation in Argentina, Bolivia, and Paraguay, T. confluens warrants further study as a potential medical concern in Brazil.
