Nyctimystes is a genus of tree frogs in the subfamily Pelodryadinae of the family Hylidae. They are principally Papuan species, but also inhabit islands in the Moluccas. All species in this genus have one distinct feature that separates them from other species in the family, the lower eyelid is marked with pattern of lines, veins, or dots. This feature presumably acts as camouflage when the frogs are at rest during the day.

Aphantophryne minuta is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is known from its type locality near Myola Guest House in the Owen Stanley Range, Northern Province, from another locality in the same province, Mount Tafa; only a single specimen is known from each locality. The specific name minuta refers to the very small size of this species. Common name Myola Guinea frog has been coined for it.
Aphantophryne sabini is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from the region of its type locality, Myola Guest House in the Owen Stanley Range, Northern Province. The specific name sabini honors Andrew E. Sabin, an American businessman, philanthropist, and environmentalist who joined the expedition during which the holotype of this species was collected. However, its vernacular name Guest House Guinea frog refers to the type locality instead.
Austrochaperina blumi is a species of frog in the family Microhylidae. It is endemic to New Guinea and known from the northern slopes of the New Guinean Central Range in Western New Guinea (Indonesia), and from the Bewani, Torricelli, and Hunstein Mountains in Papua New Guinea. The specific name blumi honors J. Paul Blum, the herpetologist who collected the type series. Common name Kosarek land frog has been proposed for it.
Cophixalus nubicola is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from its type locality, Mount Michael in the Eastern Highlands Province. The specific name nubicola refers to its cloud-swept habitat. Common name Michael rainforest frog has been coined for this species.
