Pithecheirops otion

Pithecheirops is a genus of rodent found in Borneo. The genus contains only one known species, P. otion, known as the Bornean pithecheirops. Pithecheirops is closely related to the genus Pithecheir, and the name is derived from Pithecheir and the Greek ops, meaning "resembling".[1] The only known example of this genus was caught in the Danum Valley Field Centre in Sabah, north Borneo, at approximately 150 m.[2]


Similar to Pithecheir, P. otion has long, dense, soft fur and broad feet. The two genera are distinguished by the appearance of the inner ear bones and auditory bulla.[1]


Pithecheirops was found in "dense viny roadside secondary brush on an abandoned logging road".[2] The dominant habitat of the area is lowland dipterocarp forest. Given the loss of forest and human disturbance in the area and the fact that it was found in a degraded habitat, the genus may be somewhat adaptable to habitat loss.[3]
