  Ecological and social contexts of scorpion stings in Manaus, the largest metropolis of the Brazilian Amazon Abstract Scorpion stings remain a significant public health problem in tropical regions, particularly in Brazil, where an estimatied 117,185 cases are reported annually, reflecting a persistent and growing burden on the healthcare system. Globally, more than two million cases occur each year, especially in areas undergoing environmental disturbances such as deforestation and unplanned urbanization. This study investigates the ecological and social contexts of scorpion stings in Manaus, the largest metropolis of the Brazilian Amazon. This qualitative study was conducted at the Dr. Heitor Vieira Dourado Tropical Medicine Foundation (FMT-HVD), a reference center for scorpion stings, between January 2020 and March 2025. Data were collected through clinical questionnaires, in-depth interviews, and household field observations. Thematic analysis was performed using Atlas.ti. Thir...

Abstract 


A new Brazilian genus of curtain-web spiders, family Dipluridae Simon, 1889, Harpathele gen. nov., is described, with Harpathele gymnognatha comb. nov. (Bertkau, 1880) (Rio de Janeiro state) as its type species. The new genus is a lyrate Diplurinae and it is known only from southeast Brazil. It may be recognized by the relatively small body, maxilla with dorsal transverse suture showing distinct curve at its basal third, a field of numerous long and thin setae above that suture, and a field of small rigid bristles below it, among other characters. Harpathele gymnognatha comb. nov. (Bertkau, 1880) is revalidated and redescribed, with the designation of a neotype and the first description of a male, based on specimens collected in its type locality that match the original description and illustrations, and is pointed as senior synonym of Diplura annectens (Bertkau, 1880). Additionally, two species of the new genus are described: Harpathele cariacica sp. nov., based on females from Espírito Santo state, and Harpathele salinas sp. nov., based on males from Rio de Janeiro state.
