Ansonia kraensis | |
Ansonia kraensis (Kra stream toad) is a species of toads in the family Bufonidae. It is found on the Kra Isthmus, Thailand. [3] [4] It is morphologically similar to Ansonia malayana from Malaysia, but differs from it in ventral coloration and larval morphology. [2] The exact threats are unknown but are likely forest loss for logging and agricultural expansion.
Ansonia kraensis males measure 20–22 mm (0.79–0.87 in) and females 24–28 mm (0.94–1.10 in) in snout–vent length. Tympanum is visible. Dorsum is brown with darker markings, and has small and minute warts, some of them with orange-yellow tips. Limbs have orange-yellow crossbars. Tadpoles are up to 23 mm (0.91 in) in length. Their body is flattened, dorsally black with two transverse light bands, and ventrally unpigmented. Oral disc is large. [2]
Ansonia kraensis is a forest species found near streams, sometimes also near seepages some distance away from streams. Tadpoles have been found in a small stream with moderate flow, clinging to the rocks. [1] [2]
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.
Adenomus kandianus is a species of toad in the family Bufonidae endemic to Sri Lanka. It is a high-altitude species known only from few localities. The specific name kandianus means "from Kandy" and seems to suggest that the type material came from near the city of Kandy.
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 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 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 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.
Atelopus balios, the Rio Pescado stubfoot toad, is a species of toad in the family Bufonidae. It is endemic to southwestern Ecuador, with records from Pacific lowlands in Azuay, Cañar, and Guayas Provinces. It is a rare species that was already suspected to be extinct, but a single specimen was discovered in 2011 by a team from Conservation International during a hunt for missing amphibians. The decline in amphibian populations is well documented. The Atelopus balios is Critically Endangered as a result of the widespread amphibian Chytridiomycosis fungus that has decimated other amphibian populations. There are only 10 known findings of the tadpole, Atelopus balios.
Amolops larutensis is a species of frog in the family Ranidae that is found in the Malay Peninsula from southernmost Thailand to Malaysia; records further north probably represent A. panhai.
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.
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.
Blaira is a small genus of true toads endemic to the southern Western Ghats, India. The genus was erected in 2021 as a valid substitute name for Ghatophryne which was created in 2009 for Ansonia ornata which was found to be distinct enough to warrant its own genus. This was however considered an invalid description as it was published in an only a digital medium ; Ansonia rubigina was moved based on its morphological similarity and distribution.
Ansonia echinata is a species of toads in the family Bufonidae. It is endemic to Sarawak, Borneo. Common name spiny slender toad has been coined for this little known species.
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.
Zhangixalus jarujini is a species of frog in the family Rhacophoridae. It is endemic to north-eastern Thailand and known from the Kalasin, Roi Et, and Ubon Ratchathani Provinces. The specific name jarujini honours Jarujin Nabhitabhata from the National Science Museum of Thailand. Common name Jarujin's treefrog has been coined for it.
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.
