Oreophryne wapoga
Oreophryne wapoga is a species of frog in the family Microhylidae. It is endemic to Western New Guinea (Indonesia) and is known from its type locality, the headwaters of the Wapoga River, and from the island of Papua (province), both in the Papua province. The Yapen population might represent a separate species. Description Adult males in the type series from Wapoga measure in snout–urostyle length (SUL); no females were collected. Males from Yapen are on average slightly smaller than from Wapoga, respectively SUL. A female from Yapen measures SUL. Oreophryne wapoga is morphologically similar to Oreophryne atrigularis, but the head is relatively shorter and the eyes bigger. The throat is dark brown, and the pigmentation of the body is more spotted. The ground colour is beige, grey, or brown dorsally and cream ventrally. One of the five Wapoga types has a relatively broad mid-dorsal line. Reproduction Males call from the ground or from vegetation up to above the ground. The male advertisement call is a long series of notes, lasting from about 10 seconds to half a minute. The initial notes of a call series have relatively long inter-note intervals and are followed by "fast" notes, with much higher repetition
