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 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.
Pelophryne misera, the black flathead toad or Kinabalu dwarf toad, is a species of toad in the family Bufonidae. It is endemic to northwestern Borneo and known from Sabah and Sarawak (Malaysia), although its distribution is likely to be broader and might extend to Kalimantan (Indonesia). It was first described from specimens collected from Mount Kinabalu.
Pelophryne rhopophilia, also known as lowland dwarf toad, is a species of toad in the family Bufonidae. It is endemic to Borneo and found in north-eastern and south-western Sarawak (Malaysia) and (likely) in adjacent West Kalimantan (Indonesia).
Leptobrachella palmata is a species of frog in the family Megophryidae. It is endemic to Borneo, and only known from its type locality in Lipaso Forest Reserve, Sabah, Malaysia. Common names palm Borneo frog and palm dwarf litter frog have been coined for it.
Glyphoglossus smithi, also known as Smith's squat frog or Smith's burrowing frog, is a species of frog in the family Microhylidae. It is endemic to Sabah and Sarawak in Malaysian Borneo. However, it is likely to occur more widely than currently known and be present in Brunei and Indonesia. The specific name smithi honours Dr Harrison Willard Smith, an American scientist who collected the holotype from the Limbang River district.
Kalophrynus intermedius is a species of frog in the family Microhylidae. It is endemic to Borneo and is found in Brunei, south-central Sarawak (Malaysia), and Kalimantan (Indonesia). Common names intermediate sticky frog, Sarawak grainy frog, and Mengiong sticky frog have been proposed for it.
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.
Limnonectes palavanensis is a species of frog in the family Dicroglossidae. It is found in the Palawan Island and in Borneo. The species shows paternal care, a relatively rare trait in frogs.
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 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 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.
Meristogenys phaeomerus is a species of frog in the family Ranidae. It is endemic to Borneo and known from central Sarawak (Malaysia) and adjacent Kalimantan (Indonesia). The specific name phaeomerus is derived from the Greek phaios for "dusky" and meros for "thigh", in reference to the appearance of the rear of the thigh. Common names Kapit Borneo frog and Kapit torrent frog have been coined for it.
Philautus ingeri is a species of frog in the family Rhacophoridae. It is endemic to northern Borneo and found in Sabah, Sarawak, Brunei, and adjacent northern Kalimantan (Indonesia). Common names Inger's bush frog and Inger's bubble-nest frog have been coined for it. It is named for Robert F. Inger, American zoologist from the Field Museum of Natural History.
Polypedates otilophus is a species of frog in the family Rhacophoridae. It is endemic to Borneo where it is widespread and found in Brunei, Indonesia, and Malaysia, typically in the lowlands but sometimes as high as 1,100 m (3,600 ft) above sea level. This species has prominent, sharp ridges behind the eye, above the ear, referred to in its names.
Leptomantis gauni is a species of frog in the family Rhacophoridae. It is endemic to Borneo and is found in Sabah and central Sarawak (Malaysia), Brunei, and north-eastern Kalimantan (Indonesia). The specific name gauni honours Gaun Sureng, a collector for the Sarawak Museum and a companion to Robert F. Inger on field trips when this species was observed. Common names short-nosed tree frog and Inger's flying frog have been coined for it.
Leptomantis rufipes is a species of frog in the family Rhacophoridae. It is endemic to Borneo and known from isolated locations in south-central Sarawak and eastern Sabah and central Kalimantan (Indonesia). Common names Malaysian flying frog and red-legged frog have been coined for this species. The specific name rufipes refers to the red webbing of this frog.
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). It was split off from Rana chalconota in 2009 by Robert Inger and colleagues, along with a number of other species. Common name large white-lipped frog has been coined for it.
Chalcorana raniceps, also known as the copper-cheeked frog, white-lipped frog, or Peters' Malaysian frog, is a species of "true frog" in the family Ranidae. It is endemic to Borneo, including Brunei Darussalam, Kalimantan (Indonesia), and Sarawak (Malaysia), although it is likely to occur more widely. Previously mixed with Chalcorana chalconota and believed to have much wider distribution, its range was delimited to Borneo in the revision of "Rana chalconota" complex by Robert Inger and colleagues in 2009.
