Taxonomy. Uromys caurinus Thomas, 1921,

Pulau Karakelang, Kepulauan Talaud, Indonesia.

Initially placed in genus Uromys, M. caurinuswas transferred into Melomys by O. Thomas in 1922 and then placed in subgenus Melomys as a subspecies of M. leucogaster by H. Riummler in 1936 and 1938. G. H. H. Tate in 1951 recognized caurinus as a distinct species, as did T. F. Flannery in 1995 and J. I. Menzies in 1996. A recent geometric morphometric analysis of skulls resulted in P. H. Fabreand colleagues in 2017 supporting the proximity between M. leucogaster, M. caurinus, and M. talaudium . Monotypic.

Distribution. Karakelang I and SalebabuI, in Talaud Is, Indonesia.
