【 摘 要 】

Loxosceles laeta is the species of brown spider of greatest medical importance. It causes accidents of great severity and presents synanthropic habits. In this paper, the first synanthropic record of Loxosceles laeta in the municipality of Rio de Janeiro, RJ, Brazil, is presented. This came from occasional encounters and sampling of specimens between August 2005 and June 2009. The species was recorded in a building of the Museu Nacional/UFRJ, located in the Quinta da Boa Vista park, in the urban area of the northern zone of the city of Rio de Janeiro. The focus was considered to be localized and restricted. Loxosceles laeta is adaptable to the climatic conditions of the metropolitan region of Rio de Janeiro, which makes possible for new foci of the species to become established, with occurrences of loxoscelism in the region.
