Theloderma lacustrinum, the lake bug-eyed frog, is a frog in the family Rhacophoridae. It is endemic to Laos. Scientists know it exclusively from the type locality: Ban Naxang Village near the Nam Lik Reservoir. [2] [3] [4] [1]

Appearance

The adult male frog measures 17.0–20.6 mm in snout-vent length. The skin of the dorsum is light brown in color with brown and black marks. The frog's belly is gray. The iris of the eye is bronze in color. DNA analysis has indicated that this frog is related to Theloderma lateriticum . [4]

Habitat

This frog lives in mixed evergreen forests, near streams. It has been observed 292 and 361 meters above sea level. People have seen it perched on plants 30–80 cm above the ground. Scientists believe that during the drier, cooler part of the year, it spends more time in the lower canopy, where human observers are more likely to spot it. [1]

Life cycle

Scientists believe this frog breeds through larval development, like its congeners. [1]

Threats

The IUCN classifies this frog as data deficient. It does face some danger from deforestation associated with agriculture, logging, mining, and road construction. The creation of hydroelectric dams has altered the hydrology of the area. While frogs in Theloderma have been found in disturbed areas, scientists think this one is at least somewhat forest dependent. [1]

<i>Theloderma</i> Genus of amphibians

Theloderma, the bug-eyed frogs, mossy frogs or warty frogs, is a genus of frogs in the family Rhacophoridae, subfamily Rhacophorinae. They are found from northeastern India and southern China, through Southeast Asia, to the Greater Sunda Islands; the highest species richness is in Indochina. Some species, especially T. corticale, are sometimes kept in captivity.

<i>Theloderma asperum</i> Species of amphibian

Theloderma asperum is a frog in the family Rhacophoridae. It is also known as the pied warty frog, hill garden bug-eyed frog, or somewhat informally, bird poop frog. The frog can be found in the northeastern India, Burma, China, Thailand, Cambodia, and Vietnam as well as Sumatra in Indonesia. However, because of confusion with Theloderma albopunctatum and Theloderma baibungense, it is known with certainty from its type locality in Peninsular Malaysia.

<i>Nasutixalus jerdonii</i> Species of amphibian

Nasutixalus jerdonii is a species of frog in the family Rhacophoridae. It is found in the northeastern India, in the West Bengal, Nagaland, Manipur, and Meghalaya states. It range might extend into the adjacent Nepal. The specific name jerdonii honours Thomas C. Jerdon, an English herpetologist. Common names Jerdon's bubble-nest frog, Jerdon's tree frog, and Jerdon's bush frog have been coined for this species.

Theloderma petilus, the slender warted tree frog or slender bug-eyed frog, is a frog in the family Rhacophoridae. It is occurs in Vietnam, where it has been observed in the Muong Nhe Nature Reserve. It is also native to Laos and Thailand. Scientists think it may live in China.

<i>Theloderma corticale</i> Species of frog

Theloderma corticale is a species of frog in the family Rhacophoridae. It is found in northern Vietnam, south–central Laos, and southern China.

Theloderma gordoni is a species of frog in the family Rhacophoridae. It is known from northern Thailand, northern Laos, and central to northern Vietnam. Common names Gordon's bug-eyed frog, Gordon's warted frog, and large warted treefrog have been coined for it.

Theloderma stellatum, the Taylor's bug-eyed frog, purple-spotted warted frog, spotty warted tree frog, stellar bug-eyed frog, or Chantaburi bug-eyed tree frog is a species of frog in the family Rhacophoridae. It is found in Thailand, Cambodia, Laos, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical periodically flooded lowland and montane forests between 0 and 1500 meters above sea level. This species deposits eggs in rain water collected in small tree holes; the tadpoles feed on the organic matter aggregated in a tannin-rich rain water. Notches aiming resin collection increase carrying capacity of the frogs providing additional breeding sites.
