Oreophryne alticola is a species of frog in the family Microhylidae. It is endemic to West Papua, Indonesia, and only known from the vicinity of its type locality on the New Guinea Highlands. Its natural habitat is subalpine grassland at elevations of 3,500–3,900 m (11,500–12,800 ft) asl. No significant threats to it are known.
Oreophryne anulata is a species of frog in the family Microhylidae. It is endemic to the Philippines and is known from Mindanao, Biliran, Siargao, and Leyte; it probably occurs in some smaller, intervening islands too. Common names Mindanao cross frog and Davao cross frog have been proposed for it; the latter in apparent reference to its type locality, "Davao", even though it probably is in error.

Aphantophryne nana is a species of frog in the family Microhylidae. It is endemic to the Philippines and is known with certainty only from the island of Camiguin. It is unclear whether similar frogs from northeast Mindanao are referable to this species. It was described as Oreophryne nana, but based on molecular data it was moved to Aphantophryne in 2017. Common names Camiguin cross frog, Camiguin narrow-mouthed frog, and volcano cross frog have been coined for the species.
Oreophryne notata is a species of frog in the family Microhylidae.

It is known from east of the main ridge of the Wondiwoi Mountains at the base of the Wandammen Peninsula, in the Papua province. Similar frogs have been collected from the Yapen island and the Fakfak Mountains, but it remains to be ascertained that these represent the same species. The specific name sibilans refers to the whistling advertisement call of the species.
Oreophryne unicolor is a species of frog in the family Microhylidae. It is endemic to West Papua, Indonesia, and known from the Wondiwoi Mountains at the base of the Wandammen Peninsula, Papua province. Frogs with similar call have been observed in the Fakfak Mountains, but it remains to be ascertained that these represent the same species. The specific name unicolor refers to the uniformly coloured dorsal side of the body.
Oreophryne variabilis is a species of frog in the family Microhylidae. It is endemic to Sulawesi, Indonesia. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Oreophryne wolterstorffi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from a single specimen collected from "Deutsch-Neu-Guinea", in what now is Madang Province. Common name Wolterstorff's cross frog has been coined for it.
Pseudophilautus zimmeri is an extinct species of frog in the family Rhacophoridae. It was endemic to Sri Lanka, where it was recorded from the vicinity of Galle.
