Species Description: Zweifel, R. G. 2003. A new species of Microhylid frog, Genus Oreophryne, from Papua New Guinea. American Museum Novitates, No. 3419.
Oreophryne notata is easily distinguished from all congeners with the following combination of characters: small size (<25 mm SVL), unwebbed toes, well developed digital disks, fifth toe longer than the third, and a pale inverted U-shaped marking anterior to the orbit (with bifurcated ends reaching the lip). The snout is truncated and slightly pointed when viewed dorsally, and vertically rounded in lateral view. The canthus rostralis is distinct and rounded. Eyes have horizontal pupils and red-gold irises. Tympana are small and indistinct. Both fingers and toes lack webbing. The relative lengths of the fingers are 3>2>4>1, with the first finger one-half the length of the second. All fingers have well-developed terminal disks. The relative lengths of the toes are: 4>5>3>2>1, with the fifth toe only slightly longer than the third. The clavicle is that of a typical Oreophryne, with the procoracoid reaching the scapula as a narrow cartilaginous band.The dorsal coloration is grayish brown to tan. The only marking (other than the U-shape) is a “slightly darker area on and between the posterior half of the eyelids and faint traces of lumbar ocelli.” (Zweifel 2003). The face is darker than the dorsum and makes the inverted U shape more visible since it is white. Hindlimbs have a reddish tinge. The ventral surface is translucent gray with lighter speckles (Zweifel, 2003).
