[Loxosceles Heinecken & Lowe, 1835 (Araneae; Sicariidae) species distribution in the State of Paraná].
The State of Paraná registers on average 2,577 loxoscelic accidents annually. For the elaboration of control and management programs one should first determine the distribution of the species of the genus Loxosceles. A mapping was performed of Loxosceles references in various scientific collections. A total of 1,561 spiders were found, identified as Loxosceles intermedia (67%), Loxosceles gaucho (19.5%), Loxosceles laeta (10.8%) and Loxosceles hirsuta (2.4%), originating from 20 regional and 69 municipal health districts. Loxosceles intermedia was present in all areas of the state (50 municipal districts), while Loxosceles gaucho occurred in the north and northwest, (17 municipal districts), Loxosceles laeta in the south (13 municipal districts) and Loxosceles hirsuta in the west and central areas (10 municipal districts). Paraná has four of the eight species of Loxosceles registered in Brazil. Given the medical importance of accidents caused by these spiders, it is necessary to perform studies on the location of such incidents and investigate areas that have not yet been sampled.
