Fig. 8J, K Western Sunda Spotted Stream Frog

Examine specimens.

Four specimens were collected from SRF consisted of three males (UMTZC1376, UMTZC1377, and UMTZC1387, SVL = 40 mm) and one female (UMTZC1375, SVL = 57 mm).

Identification.

Morphological characters of the specimens agreed well with the description by Chan et al. (2020c). Size (SVL: 40 mm, n = 3 males; 57 mm, n = 1 female); head longer than wide; snout pointed; tympanum distinct; supratympanic fold absent; digit tips slightly expended into small disc with circum-marginal groove; nuptial pads distinctly separated on first finger in UMTZC1376 and UMTZC1377, and slightly joined in UMTZC1387; toes slightly more than ½ webbed; dorsum smooth and indistinctly glandular; dorsum colour black; dorsum patterns with conspicuous and defined yellowish to bright orange dorsolateral stripe, dorsum and flanks with yellowish blotches; humeral gland raised and blackly pigmented in males; throat and abdomen with white spots.

Remarks.

Chan et al. (2020b, c) revised this complex and suggested that the Pulchrana picturata from the Malay Peninsula and Sumatra belong to this new species, P. sundabarat that is genetically distinct from the true Bornean P. picturata. The specimens were all found at the pristine areas in SRF. This species usually hide beneath the roots of large trees on stream banks. The distinct calls of males could be easily heard in those areas.
