Genus
Oceanella
1 species
*Oceanella* Rivalier, 1963 is a small Australian tiger beetle genus of just two species, inhabiting bare sandy and clay substrates along coastal shores. Metallic in coloration with pale spots, these slender beetles measure 8–11 mm and are active at night. Among the least-known Cicindelinae, *Oceanella* remains a genuinely enigmatic element of the Australian fauna.
