Ansonia endauensis is a species of toads in the family Bufonidae. It is endemic to the Malay Peninsula and only known from the Endau-Rompin National Park in southern Peninsular Malaysia. [1] [3] [4] [5]
The distinguishing features of the species include unique red eye color, dual vocal slits in males, and a unique combination of head, body, digit, and color pattern characteristics. [4] Males grow to at least 17.4 mm (0.69 in) and females to 28.5 mm (1.12 in) in snout–vent length. The habitus is slender. The dorsum is almost uniformly black, with orange spots on the flanks, the sides of neck and head, as well as below the eye. [2]
The species inhabits closed-canopy lowland forest. All individuals were collected from a small, rocky stream 46 m (151 ft) above sea level , where they were found in vegetation overhanging the stream bed, less than one metre above the ground. [1] [2] [4]
The known population lives within a well-protected reserve. Habitat loss caused by logging and agricultural expansion is a probably threat outside the reserve. [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.
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 guibei is a species of toad in the family Bufonidae. It is endemic to northwestern Sabah in Malaysian Borneo. The specific name guibei honors Jean Guibé, a French zoologist and herpetologist. Common names Mesilau toad and Mesilau stream toad have been coined for it.
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 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 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 penangensis is a species of toad in the family Bufonidae. It is endemic to Penang Island, Malaysia. Records from elsewhere represent other species; the mainland records are referable to Ansonia malayana and Ansonia jeetsukumarani.
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.
Pelophryne api, also known as Api dwarf toad, is a species of toad in the family Bufonidae. It is endemic to Borneo and known from Gunung Mulu National Park in northern Sarawak and from Simpang Kuda in Bau District, western Sarawak. Its genetic divergence from Pelophryne guentheri is relatively low and these species could be conspecific.
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.
Ingerophrynus gollum is a toad species in the family Bufonidae, the true toads. It is endemic to the Peninsular Malaysia and has only been recorded from its type locality in the Endau-Rompin National Park, Johor. However, I. gollum is genetically so close to Ingerophrynus divergens that its validity as a distinct species can be questioned.
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.
Ansonia latirostra is a species of toads in the family Bufonidae. It is endemic to Peninsular Malaysia and only known from two sites in the Pahang state, one near Sungai Lembing and another one near Mount Benom. It likely occurs more widely.
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.
Rentapia flavomaculata, also known as the yellow-spotted tree toad, is a species of toad in the family Bufonidae. It is endemic to the Malay Peninsula. Before being described as a distinct species in 2020, it was confused with Rentapia hosii.
Pulchrana centropeninsularis is a species of "true frog", family Ranidae. It is found in Peninsular Malaysia and Sumatra (Indonesia). The specific name centropeninsularis refers to the area of its original discovery, the state of Pahang in the central Peninsular Malaysia. Later on, it has also been recorded in the province of Jambi in east-central Sumatra. Pulchrana centropeninsularis is a rare species known from few individuals only. Prior to its description, Pulchrana centropeninsularis was confused with Pulchrana siberu, its closest relative.
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.
