Hydromyini
See text Chiropodomyini Pagès et al. 2015 Hydromyini is a very large, diverse tribe of muroid rodents in the subfamily Murinae.They likely colonized New Guinea (then a part of Sahul) from either the Sunda Shelf or the Philippines during the late Miocene or early Pliocene, about 5 million years ago, and diversified extremely rapidly.Although all were later merged into the Murinae, they were still retained as multiple tribes (Anisomyini, Hydromyini, Uromyini, and Conilurini), with other taxonomists splitting them even further.[3][4][5] Although the name "Hydromyini" derives from the semiaquatic type genus Hydromys, which translates directly to "water mouse", only a few members of the tribe such as Hydromys and Xeromys are semiaquatic; the majority are terrestrial, and some such as Notomys are even specifically adapted to arid environments.Prominent examples include the white-footed rabbit rat (Conilurus albipes), lesser stick-nest rat (Leporillus apicalis), blue-grey mouse (Pseudomys glaucus) and over half the recent species in the genus Notomys, most of which likely went extinct during the late 19th or early 20th centuries; many other species have also seen significantly reduced populations or range reductions.
