Range DescriptionHydrochous gigas occurs highly sporadically in the Main Range, Peninsular Malaysia, and the mountains of Sumatra and West Java, Indonesia (Collar et al. 2000). Records from Borneo, in Sarawak and Sabah, Malaysia, and Brunei, involve no specimen evidence and are thus treated provisionally here. All individual populations appear to be small, although one, at Gede-Pangrango, Java, was once fairly large but has seemingly now vanished.
