German's one-toothed moss mouse (Pseudohydromys germani)[1] is a species of rodent in the family Muridae which occurs in the mountains of southeastern New Guinea.

Taxonomy

It was first described in the genus Mayermys, but this genus, which only included the two one-molared species, has since been synonymised under

false water rat (Xeromys myoides) of Australia and southern New Guinea and to the three species of Leptomys, another New Guinean genus, and more distantly to other New Guinean and Australian rodents, including the water rat.[1][2]

Description

Like its relative, P. germani is a small, inconspicuous, shrew-like mouse, but it is slightly larger and has darker (dark grey as opposed to pale grey) ears and a sparsely haired tail with short hairs (the other species has more and longer hairs). Its molars, however, are even smaller (less than 1 mm) than the other species's tiny teeth. The upper incisors are

Paucidentomys
, which lacks molars entirely.

Distribution and habitat

It is known from only one specimen, an adult male which was caught at an altitude of 1300 m in the village of Munimun, Milne Bay Province, southeastern Papua New Guinea in August 1992. P. germani was first described in 2005 by biologist Kristofer Helgen and named after Pavel German, who caught the specimen.[3]
