Chalcorana megalonesa is a species of true frog in the family Ranidae, the "true frogs". [2] It is endemic to Borneo and is known from both Malaysia (Sarawak, Sabah) and Indonesia (Kalimantan). [1] It was split off from Rana chalconota (now Chalcorana chalconota ) in 2009 by Robert Inger and colleagues, [2] [3] along with a number of other species. [3] Common name large white-lipped frog has been coined for it. [1] [4]

Description

Chalcorana megalonesa are moderately large-sized frogs: adult males measure 33–48 mm (1.3–1.9 in) and females 45–66 mm (1.8–2.6 in) in snout–vent length. Body is moderately slender and legs are long. Dorsum is weakly granular. [3] Colouration is mostly green. The snout is long and pointed. Finger and toe tips have adhesive disks. It is very similar to Chalcorana raniceps in colouration and general body shape but is clearly bigger in size. [4]

Habitat

Chalcorana megalonesa occurs in tropical moist lowland and swamp forest at elevations of 20–600 m (66–1,969 ft) above sea level. Breeding takes place in small, permanent ponds (usually >30 cm deep). It can also be found in oil palm and forest concessions and appears to tolerate habitat disturbance. However, the use of pesticides and herbicides on palm oil plantations is a threat to it. It occurs in a number of protected areas. [1]

<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 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.

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.

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

Chalcorana labialis, also known as the white-lipped frog, is a species of "true frog" in the family Ranidae. As currently known, it is endemic to Peninsular Malaysia, although it might also occur in Singapore. Molecular data suggest presence of three distinct lineages in the same area, one of which is not closely related to Chalcorana labialis and which could represent an unnamed species.

<i>Chalcorana</i> Genus of amphibians

Chalcorana is a genus of frogs in the family Ranidae, "true frogs". They are found in Southeast Asia, from Thailand to Malay Peninsula and the Sunda Islands.

Papurana attigua is a species of frog in the family Ranidae, the "true frogs". It is found in central and south Vietnam, eastern Cambodia, and southern Laos. The specific name attigua is derived from Latin attiguus meaning "neighbor". It refers to the similarity of this species to Indosylvirana milleti. The common name similar frog has been coined for this species.

Chalcorana chalconota is a species of "true frog", family Ranidae. It is endemic to Indonesia and occurs in southern Sumatra, Java, Bali, and a few smaller islands. Populations previously assigned to this species now belong to a number of other Chalcorana species, leading to the current delineation of Chalcorana chalconota with a much narrower range. This species is also known as the Schlegel's frog, brown stream frog, copper-cheeked frog, or, among with many other species, white-lipped frog.

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

Chalcorana eschatia is a species of "true frog" in the family Ranidae. It is known from southern Thailand, but is likely to be more widespread. 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 macrops</i> Species of amphibian

Chalcorana macrops is a species of "true frog" in the family Ranidae. It is endemic to Sulawesi, Indonesia. Common name Masarang frog has been coined for it. The specific name macrops refers to the large eyes of this frog.

Chalcorana mocquardi is a species of "true frogs" in the family Ranidae. It is endemic to Sulawesi, Indonesia, including some offshore islands. It is probably similar in its ecological requirements to Chalcorana chalconota and is associated with small lowland forest streams. It occurs in both primary and degraded forests, provided that a reasonably closed canopy remains. Adults disperse more widely in the forest, whereas the tadpoles live in side pools and slow-flowing, deeper sections of the streams. No significant threats to this species are known.

Chalcorana parvaccola is a species of "true frog" in the family Ranidae. It is endemic to Sumatra, Indonesia. It was split off from Chalcorana chalconota by Robert Inger and colleagues in 2009, along with a number of other species. The specific name parvaccola is derived from Latin parvus meaning small and accola meaning neighbor, and refers to this species being smaller than its "neighbor", the related Sumatran species Chalcorana rufipes.

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

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.

Chalcorana rufipes is a species of "true frog" in the family Ranidae. It is endemic to Sumatra, Indonesia. It was split off from Chalcorana chalconota by Robert Inger and colleagues in 2009, along with a number of other species. The specific name rufipes is derived from Latin rufus meaning reddish and pes meaning foot, in reference to the reddish tinge on the underside of the pedal webbing in life.

Chalcorana scutigera is a species of "true frog" in the family Ranidae. However, it is a poorly known species that might actually be synonymous with Polypedates leucomystax. It is endemic to Peninsular Thailand. Common names Haut Sanuk frog and yellow trea frog have been coined for it.
