Woolley's moss mouse

Woolley's moss mouse (Pseudohydromys patriciae) is a small rodent of the family Muridae endemic to the island of New Guinea, first described in 2009 by Kristofer and Lauren Helgen. It is known only from the two type specimens, a male holotype and a female paratype, which P. A. Woolley collected in September 1988 at Porokma, about 2800 m up near Lake Habbema in the Snow Mountains of Papua Province, Indonesia. It has been recorded only from primary evergreen upper montane rainforest. Its head and body measure about 99 to 100 mm, its tail 85 to 86 mm, and it weighs about 20 to 24 g. Its describers considered it taxonomically isolated within the genus Pseudohydromys, a group of small murines with dense velvety fur, small eyes and ears and long fine whiskers. Nothing is recorded about its diet, activity or breeding. The IUCN lists it as Data Deficient; the high Snow Mountains habitats lie above the limits of traditional subsistence agriculture but are vulnerable to drought, human-set fires and resource development.
