Polypedates otilophus (also known as the file-eared tree frog,[2][3] Borneo eared frog, or bony-headed flying frog[4]) is a species of frog in the family Rhacophoridae. It is endemic to Borneo where it is widespread and found in Brunei, Indonesia, and Malaysia,[2] typically in the lowlands but sometimes as high as 1,100 m (3,600 ft) above sea level.[3] This species has prominent, sharp ridges behind the eye, above the ear, referred to in its names.[3][4]
Taxonomy[edit]
Polypedates pseudotilophus from Sumatra and (probably) Java was included in this species until 2014.[2]
Description[edit]
Males measure up to 80 mm (3.1 in) and females up to 100 mm (3.9 in) in snout–vent length.[3] The body is robust and dorsally lemon yellow in color, with many thin, black stripes; also the thighs have many black bars. The tympanum is conspicuous, with a serrated bony crest above it (the "ear"). Fingertips are expanded into large discs; those on the toes are smaller. The fingers have only rudimentary webbing whereas the toes are moderately webbed.[5] The tadpoles are yellowish green above and white below, acquiring the stripes seen in adults well before metamorphosis.[5] The largest tadpoles are 60 mm (2.4 in) in total length.[3]
Habitat and conservation[edit]
Polypedates otilophus typically occurs in secondary habitats, at the edges of primary forest, and also in villages.[5] They are most easily spotted at suitable breeding ponds where adults perch on vegetation 1–4 m above the ground.[3] It is not considered a threatened species by the IUCN.[1]
