German's one-toothed moss mouse

German's one-toothed moss mouse (Pseudohydromys germani) is a small, inconspicuous, shrew-like rodent of the family Muridae from the mountains of southeastern New Guinea. It is known from a single specimen, an adult male caught at an altitude of 1300 m near the village of Munimun in Milne Bay Province, Papua New Guinea, in August 1992. The species was described in 2005 by Kristofer Helgen and named after Pavel German, who collected the specimen. The animal has a head and body length of 105 mm, a tail of 103 mm and a weight of 29.5 g, with dark grey ears and a sparsely haired tail. It has only one molar and one incisor in each jaw quadrant, eight teeth in all, fewer than any other rodent except its close relative the one-toothed shrew mouse and the molarless Paucidentomys. It was first placed in the genus Mayermys, which was later merged into Pseudohydromys, and it belongs to the Xeromys division of the subfamily Murinae, alongside the false water rat.
