A genus of velvetfishes with a greatly compressed head and body, a large number of dorsal and anal-fin ray elements, the frontal part of the cranium with laterally-bowed ridges forming a shallow fleshy depression, and the first dorsal-fin spine arising far forward on the head just before the eyes.
The genus comprises two species, both endemic to Australia. Pseudopataecus is from the Greek pseudo (= false), in reference to the superficial but false likeness to the pataecid genus Pataecus.
