Leptobrachium smithi Matsui, Nabhitabhata, and Panha, 1999

Smith’s Spadefoot Toad ( Fig. 3F)

Two individuals of L. smithi were observed by P. Brakels and N. Maury on 25 August 2019 in Xay District , Oudomxai Province (20°39.598’N, 102°04.241’E; elevation 850 m asl) .

Morphological characters of the individuals from Oudomxai Province agreed well with the descriptions of Matsui et al. (1999) and Pawangkhanant et al. (2018). The photographed individual ( Fig. 3F) agrees with the diagnosis of L. smithi in the following characters: medium body size; snout obtusely pointed, barely projecting beyond lower jaw; canthus rostralis distinct, sharp; loreal region slightly concave; eye large, projecting from sides of head; tympanum round, distinct; supratympanic fold present; tips of fingers and toes rounded and slightly swollen; dorsal surface nearly smooth, with minute granules scattered behind; ventral surfaces weakly granular; dorsal coloration gray brown with distinct dark markings; tympanum covered with dark markings; bicolored iris (black bellow and bright yellow above).

Ecological notes. The individuals were found at ca. 2200 h on the leaf litter along the side of a road in a mountain valley. The surrounding habitat was moist evergreen forest including parts of riverine forest.

Distribution. In Laos, this species has been previously recorded from Louangphabang, Vientiane, and Xaignabouli provinces ( Pawangkhanant et al. 2018). This is the first record from Oudomxai Province. Elsewhere, this species has been reported from Myanmar, Thailand, and peninsular Malaysia ( Frost 2020).
