Ansonia phuketensis, also known as the Phuket stream toad, is a species of toad in the family Bufonidae. [1] [3] [4] It is endemic to the island of Phuket, off the south-west coast of Thailand. [1] [3]
Adult males measure 23–25 mm (0.9–1.0 in) and adult females, based on two specimens, 28–31 mm (1.1–1.2 in) in snout–vent length. The head is longer than it is wide. The snout is truncate in dorsal view and projecting, obliquely sloping in profile. The tympanum is distinct. The fingers are slender and bear weak dermal fringes. The finger tips are slightly swollen into weakly spatulate discs. The toes are moderately webbed and have tips swollen into small discs. The dorsum is brown with darker markings, often forming a reticulate pattern. The lore and lips are barred with orange-yellow. There are light yellow spots forming a row that runs from beneath the eye through the flank to the groin. The ventral surfaces and gular region are light-yellow, mottled with dark-brown. The iris is golden with black reticulations. [2]
The male advertisement call consists of a series of 2–5 distinct notes, each lasting 18–38 ms, for a total duration of 0.08–0.35 seconds. The dominant frequency is 7310–7710 Hz. [2]
Ansonia phuketensis is only known from its type locality, Kathu waterfall, on Phuket Island, at 82 m (269 ft) above sea level. Although suitable habitat exists elsewhere on the island and on the mainland, it is likely that the true range of this species is restricted; its current estimated extent of occurrence (EOO) is only 5 km2. [1]
At the type locality, Ansonia phuketensis occur near waterfalls in mountain streams no more than 5 meters wide on rocks and shrubs 1–2 meters above the ground. They are nocturnal. [1] [2] It is not known whether other types of stream habitats are suitable. It presumably breeds in steams, like other Ansonia. [1]
Ansonia phuketensis is listed as "endangered" because it is only known from a single locality and habitat deterioration is occurring in the area. Forests are fragmented by palm plantations, and urban development is also a threat. There are no protected areas within the likely range of this species. [1]
Ansonia is a genus of true toads found in south India, northern Thailand, Malay Peninsula, Tioman Island, Borneo, and Mindanao (Philippines). These small forest species spawn in streams and have torrent-adapted tadpoles. Common name stream toads has been coined for the genus, although individual species are also being referred to as slender toads.
Pelophryne, commonly known as flathead toads or dwarf toads, is a genus of true toads, family Bufonidae. The genus occurs in the Philippines, Borneo, Malaya including Singapore, and Hainan (China). Molecular data suggest that Pelophryne is the sister taxon of Ansonia.
Ansonia albomaculata, also known as the white-lipped slender toad and whitebelly stream toad, is a species of toad in the family Bufonidae. It is endemic to the island of Borneo and can be found in Sabah and Sarawak (Malaysia), Brunei, and northern Kalimantan (Indonesia).
Ansonia fuliginea, the North Borneo stream toad or North Borneo slender toad, is a species of toad in the family Bufonidae. It is endemic to Mount Kinabalu in Sabah, Malaysian Borneo.
Ansonia inthanon is a species of toad in the family Bufonidae.
Ansonia leptopus is a species of toad in the family Bufonidae. It is known from a few lowland localities in Borneo, Sumatra (Indonesia), and Peninsular Malaysia; it is reported as common in lowland Malaysian Borneo. Its presence in Peninsular Malaysia is uncertain. Its common names are brown slender toad, Matang stream toad, and cricket-voiced toad.
Ansonia longidigita is a species of toad in the family Bufonidae. It is endemic to northern and western Borneo in Sabah and Sarawak (Malaysia) and in Brunei.
Ansonia malayana is a species of toad in the family Bufonidae. It is also known as Malayan slender toad, Malaya stream toad, and pigmy false toad. It is found on the Malay Peninsula, from the Kra Isthmus (Thailand) southward to Peninsular Malaysia. However, its precise distribution in Thailand is poorly known as it may have been confused with Ansonia kraensis, described as a new species in 2005; it may also represent more than one species.
Ansonia mcgregori is a species of toad in the family Bufonidae. It is endemic to central and western Mindanao, Philippines. The specific name mcgregori honors Richard Crittenden McGregor, an Australian ornithologist who collected the holotype. Common names McGregor's toad, McGregori's river toad, and McGregor's stream toad have been coined for it.
Ansonia minuta is a species of toad in the family Bufonidae, described from the forests of Sarawak in 1960. It is known by a number of common names: tiny stream toad, dwarf slender toad, and minute slender toad. It is endemic to Borneo and occurs in tropical moist lowland forests. It is threatened by habitat loss.
Ansonia platysoma, also known as the flat-bodied slender toad and Luidan stream toad, is a species of toad in the family Bufonidae. It is endemic to the island of Borneo and known from Sabah and Sarawak, Malaysia, and from Brunei. Its closest relative is Ansonia kelabitensis.
Ansonia spinulifer, also known as spiny slender toad or Kina Balu stream toad, is a species of true toad in the family Bufonidae. It is found in Sarawak and Sabah, northern Borneo (Malaysia), and presumably also in Kalimantan on the Indonesian part of the island.
Ansonia tiomanica is a species of toad in the family Bufonidae. It is endemic to Tioman Island, off the east coast of Peninsular Malaysia.
Ansonia torrentis, also known as the Gunung Mulu stream toad and torrent slender toad, is a species of toad in the family Bufonidae. It is endemic to Mount Mulu in Sarawak, Borneo (Malaysia). The specific name torrentis refers to the habitat at its type locality, a stream running down a steep mountainside.
Ansonia kraensis is a species of toads in the family Bufonidae. It is found on the Kra Isthmus, Thailand. It is morphologically similar to Ansonia malayana from Malaysia, but differs from it in ventral coloration and larval morphology. The exact threats are unknown but are likely forest loss for logging and agricultural expansion.
Ansonia jeetsukumarani is a species of toads in the family Bufonidae. It is endemic to Peninsular Malaysia and known from its type locality, Fraser's Hill, and from Sungai Pergau. It is named in honour of Jeet Sukumaran, a biologist who has worked with Malaysian amphibians.
Sabahphrynus is a monotypic genus of amphibians in the family Bufonidae. The sole species is Sabahphrynus maculatus, also known as the spotted Asian tree toad or Sabah earless toad. It is endemic to Borneo where it is only known from Sabah, East Malaysia.
Ansonia teneritas, the gracile slender toad, is a species of toad in the family Bufonidae, described in 2016. It is endemic to central Sarawak in Malaysian Borneo and is only known from two isolated mountain ridges. Its name is derived from its slender body.
Pelophryne penrissenensis, also known as Penrissen dwarf toad, is a species of toad in the family Bufonidae. It is endemic to Borneo and only known from Mount Penrissen in Sarawak, its type locality that also gave this species its specific name. Its actual range might be wider and extend into nearby Kalimantan (Indonesia). It is the sister taxon of Pelophryne signata.
Ansonia pilokensis, also known as the Pilok stream toad, is a species of toad in the family Bufonidae. As currently known, it is endemic to Kanchanaburi Province in western Thailand, on the eastern slopes of the Bilauktaung Range. Its true range possibly extends into adjacent Myanmar. Geographically, its range is close to Ansonia thinthinae from the western slopes of the Bilauktaung Range, but A. thinthinae is more closely related to the geographically more distant Ansonia kraensis than to A. pilokensis.
