A new genus of Tanaidacea – Bunburia, collected from the region of Ningaloo in the vicinity of Bunbury (Western Australia), is erected to accommodate the new species – Bunburia prima sp. n. This genus is classified in the family Agathotanaidae and it can be distinguished from the other members of the family by having a combination of antennulae covered with minute setae, reduced uropods and unusual setation of the propodus of pereopods 4 to 6. Bunburia prima is the second species of Agathotanaidae known so far from Australia.
