Figure 1. Map of north-east Sahul and Melanesia showing the location of study sites, the modern distributions of species of Uromys, and barriers to dispersal of mesic taxa in eastern Queensland (after Bryant & Krosch, 2016). Bathymetric depth to 200 m marked in light blue. Distribution data is from Aplin & Flannery (2017), Aplin et al. (2017), Groves & Flannery (1994), Kennerley (2016), Lavery (2019), and Woinarski & Burbidge (2016). Spot distribution of U. sherrini is based on known specimens in the collections of the Queensland Museum, CSIRO National Wildlife Collection, and Natural History Museum (London).
