[2] [3] [5] It is endemic to Borneo and found in all major jurisdictions of the island Kalimantan (Indonesia), Sabah and Sarawak (Malaysia), and Brunei. [3] The specific name kajau is Berawan for "charming". [4]

Description

Males grow to 20 mm (0.8 in) in snout–vent length [4] while females can reach larger sizes. [5] The body is slender. The snout is very short and blunt. The tympanum is small and inconspicuous. The finger and toe tips are broadly rounded. The outer fingers have basal webbing the toes are half-webbed. Skin is dorsally finely shagreened. The dorsum is green above, abruptly ending at flanks, and brown posteriorly in the pelvic region, scattered white dots above. The venter is white anteriorly and transparent posteriorly. The iris is silvery below and golden above, with some dark reticulation and golden ring around pupil that is horizontally oval. [1]

The male advertisement call is soft and high-pitched. [5] Dorsum of tadpoles is brown with scattering of light bronze pigmentation on trunk and forehead. Underside of the tadpole is transparent and internal organs are visible. Tadpoles reach up to 26.7 mm (1.1 in) in total length. Eyes are positioned dorsolaterally. [6]

Habitat and conservation

Feihyla kajau occurs in primary and slightly disturbed lowland rainforests in flat and hilly terrain at elevations below 700 m (2,300 ft) above sea level, sometimes to 1,000 m (3,300 ft). [2] Individuals can be found perching on low vegetation overhanging small, rocky streams or swampy, muddy pools. [2] [5] Eggs are laid on the surface of leaves in clutches of approximately 7–10. [6]

Feihyla kajau can be common in suitable habitat. [2] [5] Parts of its range are threatened by logging concessions, small scale subsistence logging, oil palm plantations, and property development. It is present in a number of protected areas. [2]

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 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.

<i>Nanohyla perparva</i> Species of amphibian

Nanohyla perparva is a diminutive species of frog in the family Microhylidae. It is endemic to Borneo and found in Kalimantan (Indonesia), Brunei, and Sabah and Sarawak (Malaysia). The nominal species includes distinct lineages that likely represent different species. Common names least narrow-mouthed frog and Labang forest rice frog have been proposed for this species.

Meristogenys amoropalamus is a species of frog in the family Ranidae. It is endemic to northern Borneo and occurs in northwestern Sabah and northeastern Sarawak (Malaysia) and in northeastern Kalimantan (Indonesia). Common names mountain Borneo frog and mountain torrent frog have been coined for it. Studies of its larvae revealed that the nominal species contained two cryptic forms, and in 2011, Shimada and colleagues described Meristogenys dyscritus as a separate species.

Meristogenys kinabaluensis is a species of frog in the family Ranidae. It is endemic to Borneo and is found in Sabah, Sarawak (Malaysia), and Kalimantan (Indonesia). The specific name refers to its type locality, Mount Kinabalu.

Meristogenys whiteheadi is a species of frog in the family Ranidae. It is endemic to Borneo and found in both Indonesia (Kalimantan) and Malaysia. Meristogenys stigmachilus and Meristogenys stenocephalus, described as new species in 2011, were formerly included in this species. Owing to the difficulty of distinguishing these species under field conditions, the exact range of this species is uncertain. Its common name is Whitehead's Borneo frog or Whitehead's torrent frog.

<i>Chalcorana megalonesa</i> Species of amphibian

Chalcorana megalonesa is a species of true frog in the family Ranidae, the "true frogs". It is endemic to Borneo and is known from both Malaysia and Indonesia (Kalimantan).

<i>Feihyla inexpectata</i> Species of frog

Feihyla inexpectata is a species of frog in the family Rhacophoridae.

<i>Rhacophorus borneensis</i> Species of frog

Rhacophorus borneensis is a species of frog in the family Rhacophoridae. This recently (2013) described species is endemic to Malaysian Borneo where it is known from its type locality in the Maliau Basin Conservation Area, Sandakan Division, Sabah as well as from the Batang Ai National Park, Sarawak. Prior to its description, it was included in Rhacophorus reinwardtii. It is said to be "one of the prettiest frogs of Borneo". Common name Borneo flying frog has been coined for it.

Philautus kakipanjang, also known as the western long-legged bush frog and long-legged bush frog, is a species of frog in the family Rhacophoridae. As currently known, it is endemic to Sarawak in the Malaysian part of Borneo and recorded with certainty from two mountains, Gunung Serapi and Gunung Gading. Furthermore, there is an acoustic observation from Gunung Santubong that probably can be assigned to this species. The species is probably more widespread in the mountains of western Sarawak, if not beyond.
