Nyctimystes persimilis

Nyctimystes persimilis, also known as the Milne big-eyed treefrog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and known from Mount Dayman and Mount Simpson in the Owen Stanley Range.

Appearance

The type series consists of two adult males measuring 37 and 40 mm (1.5 and 1.6 in) in snout–vent length; the maximum male length in a larger material is 50 mm (2.0 in). The head is relatively broad and the snout short. The tympanum is distinct; supratympanic fold is present. The canthus rostralis is slightly curved. The palpebral venation consists of largely oblique lines, with only few horizontal interconnections, or are partly networked. The fingers are lightly webbed (basal webbing on the outer fingers), whereas the toes are more webbed, but without the webbing reaching the base of the discs. Skin is slightly roughened to rugose dorsally and coarsely granulated ventrally. Colouration of living specimens is variable but usually they are light golden brown with green or brown blotches, or plain or greyish olive with bold dark spots, or entirely darker brown. The flanks are dark with white speckling.
