Nyctimystes montanus (common name: mountain big-eyed tree frog) is a species of frog in the subfamily Pelodryadinae.[3] It is endemic to the Arfak Mountains, located in the Bird's Head Peninsula of northwestern New Guinea.[1][3] This species is only known from its type locality ("Hatam sul Monte Arfak").[1][3] There are no records of this species after it was described in 1878,[1][4] perhaps because of lack of surveys.[1]

Description

edit

The holotype—and the only known specimen[4]—is an adult male collected by Odoardo Beccari in 1875. It measures 62 mm (2.4 in) in snout–vent length. The tympanum is small. The skin of dorsum is smooth.[2] It resembles Nyctimystes kuduki but has a snout that is distinctly truncate at the tip (angular in N. kuduki). The palpebral venation has many horizontal connections (other Nyctimystes have only vertically oriented veins).[4]

Habitat and conservation

edit

The ecology and current population status of this species are essentially unknown. It is a montane frog that probably lives in streams in tropical rainforest. Threats to it are unknown. The type locality is within the Arfak Mountains National Park.[1]
