Examined specimens.

Twelve specimens were collected from SRF consisted of one juvenile (UMTZC1032, SVL = 20 mm), males (UMTZC1029, UMTZC1090, UMTZC1235, UMTZC1236, UMTZC1237, UMTZC1383, and UMTZC1384, SVL = 29-36 mm) and females (UMTZC1132, UMTZC1297, UMTZC1317, and UMTZC1622, SVL = 49-55 mm).

Identification.

Morphological characters of the specimens agreed well with the description by Berry (1975) and Hong et al. (2021). Size (SVL: 20 mm, n = 1 juvenile; 29-36 mm, n = 7 males; 49-55 mm, n = 4 females); vomerine teeth in oblique groups between choanae; snout pointed; tympanum distinct; digit tips of dilated into discs with circum-marginal grooves; first finger much shorter than second; nuptial pads present on first finger of males; toes webbed and reaching outer edge of first to third toes, inner edge of fifth toe, and fourth toe with one or two phalanges free of webbing; dorsum skin coarsely granular with weak dorsolateral fold; dorsum colour variable from pale green, brownish or pale yellow.

Remarks.

This species can be found at many swampy locations and flowing streams within SLF. Chalcorana labialis was usually observed perched on the surface of low vegetation along the streams and swampy areas, and was occasionally found at artificial ponds. All collected and observed individuals were found lower than 2 metres from the ground.
