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. [2] [4] The specific name macrophthalmus is derived from the Greek words macros (="large") and ophthalmos (="eye") and refers to the large eyes of this frog. [3] Common names Matsui's Borneo frog, [2] large-eyed torrent frog, [1] and big-eyed torrent frog have been coined for it. [5]

Description

This species is only known from the holotype, which is an adult male measuring about 37 mm (1.5 in) in snout–vent length. [3] [4] The body is moderately stout. The snout is somewhat blunt. The eyes are large (diameter 6.5 mm (0.3 in)). The tympanum is distinct and also relatively large. The fingers and the toes bear round discs; the toes are fully webbed. Skin is shagreened above. There is a low, glandular dorsolateral fold. The flanks are coarsely granular, the throat smooth, and the venter rugose. Coloration of living animals is unknown; the preserved specimen is grayish-brown dorsal with some indistinct markings. The upper lip is whitish. The limbs have crossbars dorsally. The underside is whitish. [3]

Habitat and conservation

Meristogenys macrophthalmus live primary, hilly, lowland rainforest. Breeding takes place in streams. It is threatened by habitat loss (clear-cutting). [1]

<i>Meristogenys</i> Genus of amphibians

Meristogenys is a genus of true frogs from Borneo. Its tadpoles are adapted to fast-flowing mountain streams and easily recognizable by their divided upper lip with ribs on the outside.

<i>Amolops larutensis</i> Species of frog

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.

Amolops mengyangensis is a species of frog in the family Ranidae. It is known with certainty only from its type locality, the eponymous Mengyang in Xishuangbanna Dai Autonomous Prefecture, southern Yunnan province of China. However, if Amolops daorum is its junior synonym, distribution of Amolops mengyangensis would be considerably wider, including the vicinity of Sa Pa in northern Vietnam near the Chinese border, Hong Kong, and Houaphanh Province in eastern Laos, and presumably also including the intervening areas. This more inclusive species circumscription was taken in the latest assessment of this species for the IUCN Red List of Threatened Species from 2008.

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.

<i>Meristogenys jerboa</i> Species of frog

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.

<i>Meristogenys orphnocnemis</i> Ppecies of frog in family Ranidae

Meristogenys orphnocnemis is a species of frog in the family Ranidae, sometimes known as Sabah Borneo frog or dusky-footed torrent frog. It is endemic to Borneo and found in the mountains of Sabah (Malaysia), Brunei, and East Kalimantan (Indonesia). Its natural habitats are hilly lowland rainforest, also occurring in slightly disturbed forests. Tadpoles live in clear, rocky forest streams where they cling to rocks in strong currents. Siltation of streams caused by deforestation is a threat to this species.

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.

Meristogenys poecilus is a species of frog in the family Ranidae. It is endemic to Borneo and known from between central Sarawak (Malaysia) and central Kalimantan (Indonesia). The specific name poecilus is derived from the Greek poikolos, meaning "pied" or "blotched", in reference to diagnostic pattern on rear of the thigh. Common name Malaysian Borneo frog has been coined for this species.

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.

The Amami tip-nosed frog is a species of frog in the family Ranidae. It is endemic to the Amami Islands, a part of the Ryukyu Islands, Japan. Specifically, it is known from the islands of Amamioshima and Tokunoshima.

Odorrana supranarina is a species of frog in the family Ranidae. It is endemic to Ryukyu Archipelago, Japan, and is known from the islands of Ishigaki and Iriomote, both in the Yaeyama Group. The specific name supranarina refers to the large size of this species —at the time of the species description, it was the largest member of the so-called Rana narina complex. Common name greater tip-nosed frog has been coined for it.

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

It was split off from Chalcorana chalconota by Robert Inger and colleagues in 2009, along with a number of other species in so-called "Rana chalconota group". The specific name eschatia, derived from the Greek word for "outskirt", refers to distribution of this species being at the edge of the geographical range of the group.

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

Meristogenys maryatiae, also known as Maryati's torrent frog, is a species of frog in the family Ranidae. It is endemic to the state of Sabah, in the Malaysian part of Borneo. The specific name honours Prof. Datin Mohamed Maryati, entomologist from the Universiti Malaysia Sabah, who helped the describers of this species during their herpetological surveys in Sabah.

Leptobrachella bondangensis is a species of frog in the family Megophryidae. It is endemic to Central Kalimantan, in the Indonesian part of Borneo, and is only known from its eponymous type locality, Mount Bondang in the Murung Raya Regency. Common name Bondang dwarf litter frog has been coined for this species.

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.
