Aaaaba is a genus of beetles from the Buprestidae family. It inhabits locations along the east coast of Australia. It was described in 1864 by Achille Deyrolle as "Alcinous", a junior homonym of a genus of pycnogonids. In 2002, Charles Bellamy gave it the replacement name "Aaaba", but this proved to be another junior homonym, of a genus of sponges. In 2013, it was given a further replacement name, becoming Aaaaba. There are two species within this genus: \n* Aaaaba nodosus (Deyrolle, 1865) \n* Aaaaba fossicollis (Kerremans, 1903)
