Lycosa erythrognatha is a species of spider from the genus Lycosa .^[1]^[2] The species was originally described in 1836.^[3] It is the only spider known to feed on Rhinella ornata .^[4]

Venom

Beginning in the 1920s, the venom of this species has been erroneously reported to cause necrosis in humans, based on undocumented clinical observations; careful empirical studies revealed that none of over 500 confirmed bites from this spider resulted in a necrotic wound.^[5]
