This species is known only from few localities in New Guinea, with the only records being from nine sites in the 1980s and 1990s. The  population size is unknown and it is described as apparently very scarce or rare. There is no information on its likely distribution extent, population trends, or threats, although it is potentially threatened by logging of lowland forests. For these reasons, it is classified as Data Deficient.

Geographic Range [top]

Range Description: Uroglaux dimorpha is sparsely distributed in New Guinea (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea), known only from few localities in the north-west, including Yapen island, near Vanimo and Lae, the south-east and Gulf Province (Coates 1985, Beehler et al. 1986, Lamonthe 1993).
