Nuttalliella

Nuttalliella is genus of tick. It contains a single living species, Nuttalliella namaqua found in southern Africa, having been reported from Tanzania, Namibia and South Africa, with fossil species of the genus having been reported from the mid-Cretaceous (~100 million years ago) Burmese amber of Myanmar. It is the only living member of the family Nuttalliellidae, and the most primitive living lineage of tick. It can be distinguished from ixodid ticks and argasid ticks by a combination of characteristics including the position of the stigmata, lack of setae, strongly corrugated integument, and form of the fenestrated plates.
