Acanthogonatus confusus is a mygalomorph spider of Argentina and Chile its name referring to the confusion between this species and A. subcalpeianus. Males are recognized by their long palpi together with the absence of a tibial apophysis; females are recognized by the spermathecae (similar to A. fuegianus A. centralis and A. parana which have – unlike A. Confusus – no inferior tarsal claws on tarsus IV).
