Abstract

Mayermys is the only muroid genus with a single molar in each quadrant of the jaw. This distinctive genus is restricted to montane New Guinea and has previously been considered monotypic. Here a second species of Mayermys is described from the mountains of far south-eastern Papua New Guinea. The dentition of this new species is more reduced than that of any other species of rodent, living or fossil.

Key words

Murinae Muridae Papua New Guinea taxonomy 

Eine neue Muriden-Art (Gattung Mayermys) aus dem Südosten von Neuguinea

Zusammenfassung

Mayermys ist die einzige Nagetier-Gattung mit nur einem einzigen Molaren in jedem Kieferast. Diese markante Gattung ist auf Gebirge in Neuguinea beschränkt und gilt bisher als monotypisch. Hier wird eine zweite Art von Mayermys aus dem äußersten Südosten der Insel beschrieben. Die Bezähmung dieser neuen Art ist stärker reduziert als die irgendeiner anderen lebenden oder fossilen Nagetier-Art.
