One specimen was collected from SRF (UMTZC1761, SVL = 18 mm). Identification. Morphological characters of the specimen agreed well with the description by Berry (1975) , Sumarli et al. (2015) , and Manthey et al. (2016) . Size (SVL = 18 mm, n = 1 male); rounded snout; upper eyelid with dermal tubercles; tympanum hidden; first finger much shorter than second; finger tips lacking discs; toe tips dilated into well-developed discs and bearing circum-marginal grooves; toes fully webbed and reaching to discs of all except fourth toe; subarticular tubercles obscured; distinct metatarsal tubercles; dorsum skin smooth with few tubercles. Remarks. Microhyla superciliaris can be easily mistaken for M. butleri that occurs syntopically in the leaf litter at SLF. This species is a new record for the amphibians in Hulu Terengganu.
