| Ansonia echinata | |
Ansonia echinata is a species of toads in the family Bufonidae. It is endemic to Sarawak, Borneo. [2] [3] Common name spiny slender toad has been coined for this little known species. [3]
The specific name echinata is derived from Latin echinatus, meaning "thorny", and refers to the spinose tubercles on top of the snout and on the sides. [1]
Ansonia echinata is endemic to Malaysian Borneo where it is only known from its type locality, Bukit Kana, a small and isolated hill in Bintulu Division, Sarawak. [2] [3] [4]
The type series consists of four adult males that measured 20–21.3 mm (0.79–0.84 in) in snout–vent length; this means that Ansonia echinata is a relatively small species among the Bornean Ansonia. The habitus is stocky. The canthus is sharp. The tympanum is visible and slightly greater than half eye in diameter. The dorsal surfaces are covered with tubercles. The snout, sides, and limbs bear tubercles with small black spines (the ones that have given the species its name). The toes are partially to fully webbed. The finger and toe tips are rounded but not expanded. [1] The colour in life is unknown; [3] in preservative, the dorsum is dark brown and the raised tubercles are yellowish brown. Ventral colouration is light yellowish brown without pattern. The limbs have dark crossbars. [1]
Males have subgular vocal sacs with a slit-like opening in the floor of the mouth. [1] Female Ansonia echinata are unknown. [3] [4] Hertwig and colleagues discuss the possibility that Ansonia vidua , known only from two female specimens, could be conspecific with Ansonia echinata. Based on morphological and ecological differences, they conclude that the two are separate species, although lack of tissue samples from A. echinata means that this question could not be settled with molecular methods. [4]
Three kinds of Ansonia tadpoles were collected at the type locality. One of them belongs to Ansonia longidigita , whereas the other two could not be assigned to species. Because tissue samples were not available, it was not possible to ascertain which one of them, if any, belongs to Ansonia echinata. Maximum recorded total lengths of these two tadpole types tadpoles were 6.9 and 9.4 mm (0.27 and 0.37 in). [1]
The type series was collected near a small stream (3 metre in width) in primary rain forest at about 250 m (820 ft) above sea level. All of them were perched on leaves up to 1 metre above ground. In addition, a juvenile was found in the stream itself. [1] Otherwise, the natural history of this species is unknown. [3]
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 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 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 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 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.
Phrynoidis juxtasper, also known as the giant river toad or Borneo river toad, is a species of toad in the family Bufonidae. It is found in Borneo and Sumatra (Indonesia) below 1,600 m (5,200 ft) asl. Prior to its species description, it was confused with Phrynoidis asper.
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.
Meristogenys jerboa is a species of frog in the family Ranidae. It is endemic to western Sarawak in Borneo. Common names western torrent frog, Matang torrent frog, and Gunther's Borneo frog have been coined for it. Many cryptic species have been separated from this species. Based on mitochondrial DNA, current "true" Meristogenys jerboa still includes two major lineages. However, because the lineages occur in sympatry and do not differ in morphology, Shimada and colleagues elected to treat them as intraspecific variants.
Meristogenys macrophthalmus is a species of frog in the family Ranidae. It is endemic to Sarawak in northern Borneo (Malaysia) and is only known from its type locality in the Bintulu District. The specific name macrophthalmus is derived from the Greek words macros (="large") and ophthalmos (="eye") and refers to the large eyes of this frog. Common names Matsui's Borneo frog, large-eyed torrent frog, and big-eyed torrent frog have been coined for it.
Robert Frederick Inger was an American herpetologist. During his lifetime, he wrote numerous books and publications about herpetology. He was also the curator for amphibians and reptiles at the Field Museum in Chicago, Illinois.
Ansonia vidua is a species of toads in the family Bufonidae. It is endemic to Sarawak, Borneo. Common names Murud black slender toad and widow slender toad have been coined for this little known species. The latter name refers to the black colouration of this species and the fact that no male individuals are known.
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 saravacensis, also known as Sarawak dwarf toad, is a species of toad in the family Bufonidae. It is endemic to Borneo and only known from Sarawak ; there are records from at least four localities representing three different divisions.
