Genus Hannia
Summary:
An obligate freshwater teraponid genus distinguished from all others in the family by the presence of two spines on the first proximal dorsal pterygiophore, a lack of adult vertical striping, a distinct foramen for the exit of blood vessels from the third hemal arch anterior to the parahypural vertebrae, and by having relatively few (32–38) lateral-line scales (Shelley et al. 2021).
The genus is named Hannia in reference to the type locality of the genus, the Hann River of the Kimberley region, Western Australia.
