Chalcorana eschatia is a species of "true frog" in the family Ranidae. [1] It is known from southern Thailand, but is likely to be more widespread. [1] It was split off from Chalcorana chalconota (then Rana chalconota) by Robert Inger and colleagues in 2009, [1] along with a number of other species in so-called "Rana chalconota group". [2] 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. [2]

Description

Chalcorana eschatia are moderate-sized frogs: adult males measure 31–40 mm (1.2–1.6 in) and females 43–57 mm (1.7–2.2 in) in snout–vent length. Body is slender and legs are long. The snout is obtusely pointed, but rounded in profile. The tympanum is distinct, slightly larger in males than in females. The outer fingers have large discs; no webbing is present but the middle fingers have sin folds. The toe tips have discs that are smaller than the fingers ones. The webbing between the toes is extensive. Dorsal skin is granular. Preserved specimens are dark brown dorsally and on the sides; no black spots are present. The venter is whitish or cream-colored, sometimes with round dark spots on the throat. Crossbars on the hind limbs are lacking. [2]

Habitat and conservation

No specific ecological information accompanied the species description, but it was noted that this species (along other related species) appears to be restricted to perhumid forests. [2]

As of early 2019, this species has not been assessed for the IUCN Red List of Threatened Species. [3] The entire type series was collected in a number of national parks: Ngao Falls National Park (the type locality), Khao Luang National Park, Khao Phanom Bencha National Park, Khao Sok National Park, and Kaeng Krung National Park.

Hose's frog is a true frog species with a wide range in Southeast Asia. This species was named after zoologist Charles Hose.

Leptopelis crystallinoron is a species of frog in the family Arthroleptidae. It is endemic to Gabon and only known from the area its type locality near the Barrage de Tchimbélé in the central Monts de Cristal. Only one specimen was known until five specimens were captured in the Crystal Mountains National Park in 2009. It is probable that this species is endemic to the Monts de Cristal and that its range extends into Equatorial Guinea.

Leptopelis oryi, also known as the Garamba forest treefrog and Ory's tree frog, is a species of frog in the family Arthroleptidae. It is found in the northeastern Democratic Republic of the Congo, northwestern Uganda, and adjacent South Sudan. It is morphologically similar to Leptopelis nordequatorialis from Cameroon, and has also been considered its synonym, but is currently treated as a distinct species. The specific name oryi honours Albert Ory, warden in the Garamba National Park, the type locality of this species.

Leptopelis parvus, also known as the Kanole forest treefrog, is a species of frog in the family Arthroleptidae. It is endemic to the Democratic Republic of the Congo and is only known from the Upemba National Park.

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

Amolops spinapectoralis is a species of frog in the family Ranidae, the "true frogs". It is at present only known from a few locations in central Vietnam—that is, it is endemic to Vietnam—but it is likely to be found more widely in the Vietnamese Central Highlands as well as in the adjacent southeastern Laos and northeastern Cambodia. The specific name spinapectoralis is derived from Latin spina for "thorn" and pectoralis for "of the breast" and refers to the pectoral spines in adult males. Common name spinyback torrent frog has been coined for it.

Amami tip-nosed frog Species of amphibian

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.

Ingerana charlesdarwini is a species of frogs in the family Dicroglossidae. It is endemic to the Andaman Islands, India, and is known from the South Andaman Island, Long Island, and North Andaman Island.

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.

Odorrana utsunomiyaorum 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 utsunomiyaorum honours Taeko and Yasuaki Utsunomiya for their contributions to clarifying the amphibian fauna of the Yaeyama Group.

Rhacophorus baliogaster, also known as the belly-spotted frog, is a species of frog in the family Rhacophoridae. It is found in the Central Highlands of Vietnam and the Annamite Mountains of adjacent Laos. Its range probably extends into eastern Cambodia where suitable habitat should be present. The specific name baliogaster is derived from the Greek words balios and gaster, meaning "spotted or dappled belly".

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.

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 macrops</i> Species of amphibian

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.

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.

Papurana supragrisea is a species of true frog, family Ranidae. It is endemic to New Guinea, including some nearby islands. It is known with certainty only from southeastern New Guinea and from the D'Entrecasteaux Islands. However, this name has been used more broadly for a species complex that is widely distributed in the mountains of New Guinea. Common name Papua gray frog has been coined for it.
