Delena cancerides, the flat huntsman spider or social huntsman spider, is a large, brown huntsman spider native to Australia. It has been introduced to New Zealand, where it is sometimes known as the Avondale spider as they are commonly found in the suburb of Avondale, Auckland. This was the species used in the beginning of the movie Spider-Man and widely in Arachnophobia, and both films depict them as having a deadly venomous bite, but they are generally considered harmless to humans in real-life. It was first described by Charles Athanase Walckenaer in 1837.
