The Aviculariinae are a subfamily of spiders in the family Theraphosidae (tarantulas). They can be distinguished from other theraphosids by a number of characters. Their legs have no or few spines on the underside (ventral surface) of the tibial and metatarsal joints of the legs. The last two leg joints (the metatarsi and tarsi) have brushes of hairs (scopulae) that extend sideways, particularly on the front legs, giving them a spoon-like (spatulate) appearance. Females have two completely separated spermathecae.
