Howidipterus donnae was named by Long (1992) [A lungfish having a maximum body length up to 0.5 m. Skull roof approximately 82% as broad as long, and dermal bone pattern highly variable; general configuration with B bone one third as long as skull; C bones equidimensional with E bones; (both E and C being as long as B). D small, being about half the length of the C bones, and about two thirds as broad as long. Paired rostral ossifications anterior to E bone, rest of snout unossified. Occipital commissure passes through A bone. Cheek with deep lA+B bone, separate small 1 C bone. Pterygoid toothplates elongated, subtriangular in form with up to 17 toothridges. Toothridges terminate in the mesial half of each toothplate which has a concave surface, but isolated cusps may be present in this region. Small, narrow anterior median toothed bone present anterior to upper jaw toothplates. Parasphenoid with a diamond-shaped corpus half total length of bone and lacking a buccohypophysial foramen. Externally exposed regions of scales bearing widely-spaced thin bony ridges. ]. It is not extant. Its type specimen is NMV P181884, a partial skull (a cranium showing little abnormal fusion or space capture between skull roof elements). Its type locality is Howidipterus-type locality, which is in a Givetian lacustrine mudstone in the Bindaree Formation of Australia.
