ABSTRACT
Loxosceles spiders are a public health problem in many regions of the world by causing severe dermonecrosis and/or complement dependent haemolysis upon envenomation. Loxosceles spiders are present in several different habitats, including the karstic environment. Due to the substantial increase of tourism in caves of Brazil in the last few years and the medical importance of these arachnids the mapping Loxosceles species in karstics areas of this country is important. Caves of Parque Estadual Turstico do Alto Ribeira (Iporanga, So Paulo State, Brazil) have been surveyed in order to identify the presence of L. adelaida in that important touristic circuit in Brazil, which is visited by thousands tourists every year. This study includes preliminary ecological observations about the behavior of L. adelaida within the caves and in the adjacent forest outside of the caves.]]>
