Ziegler's water rat

Ziegler's water rat (Hydromys ziegleri) is a semiaquatic rodent native to the mountains of Papua New Guinea, described in 2005 by K. Helgen and named in honour of the late Dr. Alan C. Ziegler of the Bishop Museum. Little is known of it: only two specimens have ever been recorded by scientists, from Bainyik on the south slopes of the Prince Alexander Mountains at about 200 metres. It has been found in creeks and rivers in low-lying tropical rainforest and may also live at higher elevations. The International Union for Conservation of Nature rates it as data deficient because its range, threats and numbers are not well enough known, and logging of its forest habitat may threaten it, though that needs more research.
