Trygonoptera is a genus of round rays endemic to the waters around Australia. Müller and Henle defined Trygonoptera in 1841.{{cite book |author=Müller, J. and F.G.J. Henle |date=1838–41 |title=Systematische Beschreibung der Plagiostomen |publisher=Veit und Comp |page=173–174}} It has often been considered synonymous with Urolophus, but this has been refuted by recent studies.{{cite journal |author=Séret, B. and P.R.
