Leptobrachium smithi (common name Smith's litter frog) is a species of frog found in Southeast Asia. Its specific name honours Malcolm Arthur Smith, one of the early herpetologists to study the amphibians of Thailand. Leptobrachium smithi is a moderate-sized Leptobrachium, with males measuring 36–68 mm (1.4–2.7 in) snout-vent length and females 50–78 mm (2.0–3.1 in) SVL. They have a relatively big, depressed head with striking eyes with upper half of iris scarlet or yellow. Skin above is nearly smooth but with minute granules scattered behind, especially around vent; ventrally granular.
Its type locality is Ton Nam Plu Waterfall, Khao Chong, in Trang Province, southern Thailand. It is also known from adjacent southern Myanmar and from Laos. It may also occur in northeastern India and Bangladesh and in Peninsular Malaysia (Pulau Langkawi). Prior to its description, it was confused with Leptobrachium hasseltii and Leptobrachium pullum. Leptobrachium smithi is a locally common species that is found on the ground in evergreen forest in monsoon and rainforest climatic regions, as well as dense mixed deciduous forest. Tadpoles are found in deep sections... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Smith's Litter Frog is recorded against all the amphibians logged in Khao Sok National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
