Abstract
A new osteolepiform fish, Beelarongia patrichae gen. et sp. nov., is described from the Late Devonian (Frasnian) lacustrine Mount Howitt site, eastern Victoria. Beelarongia is cosmine-covered, has a broadly flaired parietal shield with large extratemporal bones, cheek plate with an additional small postorbital bone and broad lateral extrascapulars. The orbits are very small. The scales are rhombic with high dorsal processes. Beelarongia is considered closely related to Canowindra grossi Thomson because of the shape of the parietal shield, presence of an accessory postorbital bone behind the small orbit, and broad extrascapular series.
