Phoneutria is a genus of venomous spiders in the family Ctenidae of potential medical significance to humans. They are mainly found in tropical South America, with one species in Central America. Two species, Phoneutria fera and Phoneutria nigriventer, are known as the Brazilian wandering spider; the genus as a whole is sometimes called Brazilian wandering spiders, although not all species occur in Brazil. Other English names include armed spiders (armadeiras in Brazilian Portuguese) and banana spiders (a name shared with several others).
