Leptobrachium smithi (common name Smith's litter frog) is a species of frog found in Southeast Asia.[3] Its specific name honours Malcolm Arthur Smith, one of the early herpetologists to study the amphibians of Thailand.[2]
Description[edit]
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.[2]
Distribution[edit]
Its type locality is Ton Nam Plu Waterfall, Khao Chong, in Trang Province, southern Thailand.[2] 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.[3]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 of forest streams with little current.[1]

All confirmed records of this species are from northern, northeastern, western and Peninsular Thailand, northeast India (Assam and Meghalaya) southeastern Bangladesh (Chittagong and Rangamati Hill-district), southern Myanmar and western Lao People's Democratic Republic. It might extend into northern Peninsular Malaysia (P. van Dijk and R. Sukumaran pers. comm.). Altitude records range between 60 and 1,350 m asl.

Tadpoles of Leptobrachium smithi have a deep body, and tadpoles of stages 26-31 measured 14.2-19.7mm from head to tail. In January, multiple sizes were found in pools along streams. They are light brown in color with many small darker, irregular dorsal spots, even on the sides of the tail. The base of the tail has a light area bounded with two dark bands. The ventral surfaces have no spotting (Matsui et al. 1999)

Matsui et al. 1999 noted males started calling together, just after sunset. Males called when away from water, on the forest floor. Matsui et al. 1999 recorded multiple populations: at Phu Luang, Doi Suthep, Mae Hong Son, Erawan, Khao Luang, and Khao Chong. All showed similar call characteristics. Calls consisted of a varying number (1-7) of notes, each of which was composed of unclear pulses and lasted 100-600 msec. The dominant frequency was between 600-1700hz. Harmonics were between 3000-8000hz. Calls showed slight frequency modulation and strong intensity modulation (Matsui et al. 1999).
