Barygenys exsul is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea. It is known from Rossel (type locality) and Sudest Islands in the Louisiade Archipelago, east of New Guinea. [1] [2] [4] It is uncertain whether the specimens from Sudest really are conspecific with this species. Barygenys apodasta and Barygenys resima were mixed with this species prior to their description in 2013. [4]

Description

Adult males measure 22.4–25.5 mm (0.88–1.00 in) and females 22.8–38.9 mm (0.90–1.53 in) in snout–vent length. The eyes are small. The tympanum is not evident or is indistinct. The fingers are short, unwebbed, and with rounded tips but lacking discs; the toes are unwebbed and have discs that are barely wider than width of penultimate phalanges. Coloration is dark brown or mud-brown, speckled with black or with obscure darker brown markings. Sometimes they can be uniform dark brown, or have a broad mud-brown vertebral stripe. [4]

Males call at night from beneath the surface of the soil. The call is a rapid series of 4–9 boops. [4]

Habitat and conservation

Its natural habitats are primary or secondary lowland rainforests and cloudforests, [1] and have been found at altitudes up to 720 m (2,360 ft) above sea level. [4] It is a fossorial species [1] that can be moderately common several centimeters beneath the soil surface. [4] Development is presumably direct [1] (i.e, there is no free-living larval stage [5] ).

The species is not facing major threats. It is utilized on Tagula for magic purposes—to provide fertility to land if planted—but the level of utilization is likely too low to constitute a major threat. [1]

Barygenys is a genus of microhylid frogs. They are endemic to New Guinea and the adjacent Louisiade Archipelago. So far only known from Papua New Guinea, the range of the genus is expected to reach Papua province in the Indonesian part of New Guinea. Despite not being known from Papua, common name Papua frogs has been suggested for them.

Austrochaperina aquilonia is a species of frogs in the family Microhylidae. It is endemic to the Sandaun Province, north-western Papua New Guinea. It is only known from two nearby locations in the Torricelli Mountains: Mount Somoro and from the village of Wilbeite. The specific name aquilonia is a Latin adjective meaning "northern" and refers to the range of this species in the north coast mountains of New Guinea.

Copiula guttata is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from around the head of the Gulf of Papua in the Gulf and Chimbu Provinces. The specific name is the Latin adjective guttata that means "spotted" and refers to the dorsal colour pattern of this species. Based on molecular evidence, it was transferred from Austrochaperina to Copiula in 2016.

Copiula rivularis is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from near the Indonesian border east to the Morobe Province; it is expected to occur in the Papua province of Indonesia. The specific name comes from the Latin adjective pertaining to small brooks or streams and refers to the habitat of this species. Based on molecular evidence, it was transferred from Austrochaperina to Copiula in 2016.
