Abstract
The genus Lasiodora (Koch 1850) belongs to the family Theraphosidae (suborder Mygalomorphae) and is found solely in Latin America. Of the 39 known species, 25 are endemic in Brazil, where they are commonly known as “caranguejeiras.” Despite their large size and fearful appearance, the bites of these spiders are not life-threatening for humans, and the clinical signs and symptoms presented by the victims of bites are of mild severity, with local pain, edema, and erythema. Research regarding toxinology has focused mainly on venoms from medically important animals. As such, Lasiodora venom has not been systematically studied. Nevertheless, even though the venom from Lasiodora spider is only mildly harmful to humans, it may have therapeutic potential. The toxicity of Lasiodora venom to vertebrates and invertebrates and its pharmacological activities, including its cardiovascular effects, have only occasionally been investigated. These studies were performed using the spiders Lasiodora spp., which are mainly native to southeast Brazil, and Lasiodora parahybana, which is mainly native to northeast Brazil. They demonstrate that Lasiodora venom is a promising study material, as it is rich in biomolecules that are active on vertebrate and invertebrate receptors that to date are uncharacterized.
