Gallieniellidae is a family of spiders first described by J. Millot in 1947.[1] It was originally thought to be endemic to Madagascar until species were also found in southern Kenya,[2] northeastern Argentina,[3] and Australia. Drassodella was transferred from the family Gnaphosidae in 1990.[4] They are suspected to be specialized in ant-preying.
