Synonyms[1]
  • Leptosparassus Järvi, 1914[2]
  • Streptaedoea Järvi, 1914[2]

They are commonly found in tall grass and on the bark or branches of trees. At least two species have adapted to urban environments and have been found indoors. They are large and somewhat aggressive spiders, but their venom is not toxic enough to be dangerous to humans.[4]
