Oreophryne geislerorum (also known as the Madang cross frog) is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea where it is known from the northern coast between the tip of the Huon Peninsula and south and east to Kokoda and Popondetta. [1] [2] [3] [4] The specific name geislerorum honours two German taxidermists, Bruno Geisler and his brother Herbert Geisler. [5]

Description

Adult males measure 21–27 mm (0.83–1.06 in) and adult females 24–29 mm (0.94–1.14 in) in snout–vent length. The canthus rostralis is moderately distinct. The tympanum is barely distinct. The fingers and the toes have well-developed terminal disks. The fingers have no webbing whereas the toes have basal webbing. The dorsum is yellowish brown to brown. Darker markings may be present. The ventrum is yellow to grayish white. [3]

The male advertisement call is "harsh" with rapidly repeated notes. Individual notes are not discernible to the human ear. The rate of repetition varies considerably between individuals, about 50–135 notes per second, but is more constant for individual frogs. [3]

Habitat and conservation

Oreophryne geislerorum occurs in rainforests, rural gardens, and urban areas at elevations up to about 1,400 m (4,600 ft) above sea level [1] Active by night, males call from shrubs and trees, sometimes high up. They have been observed to lay eggs inside the stalk of a banana leaf near the main stem. [3] Development is direct, without free-living tadpole stage. [1]

Oreophryne geislerorum is a very common, adaptable species that is not facing any known threats. Its range includes the Kamiali Wildlife Management Area. [1]

Nyctimystes kubori is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and is widespread in the New Guinea Highlands between 141°E and 147°E and in the mountains of the Huon Peninsula. The specific name kubori refers to its type locality in the Kubor Mountains. Common name sandy big-eyed treefrog has been coined for this species.

Nyctimystes narinosus, the common big-eyed treefrog, is a species of frog in the family Pelodryadidae, or alternatively, subfamily Pelodryadinae in the family Hylidae. It is endemic to New Guinea and occurs in the Wahgi-Sepik Dividing Range and the Schrader Mountains, on both sides of the border between Papua (Indonesia) and Papua New Guinea. There is, however, some uncertainty about the western limit of this species. Despite its vernacular name, Nyctimystes narinosus is not a common species.

Nyctimystes persimilis, also known as the Milne big-eyed treefrog, is a species of frog in the family Pelodryadidae, also treated as the subfamily Pelodryadinae in the family Hylidae. It is endemic to Papua New Guinea and known from Mount Dayman and Mount Simpson in the Owen Stanley Range.
