Examined specimens.

Twenty adult specimens were collected from SRF (Males: UMTZC1164, UMTZC1170, UMTZC1171, UMTZC1172, UMTZC1173, UMTZC1174, UMTZC1233, UMTZC1299, and UMTZC1304, SVL = 32-66 mm; Females: UMTZC1009, UMTZC1044, and UMTZC1063, SVL = 54-96 mm) and SAP (Males: UMTZC1348, UMTZC1351, UMTZC1385, and UMTZC1504, SVL = 32-50 mm; Females: UMTZC1306, UMTZC1323, UMTZC1380, and UMTZC1481, SVL = 48-98 mm).

Identification.

Morphological characters of the specimens agreed well with the description by Berry (1975) and Hong et al. (2021). Size (SVL: 32-66 mm, n = 13 males; 48-98 mm, n = 7 females); vomerine teeth in two oblique series behind choanae; head as long as broad with pointed snout; tympanum distinct; supratympanic fold; tips of digits expanded into large discs with circum-marginal grooves; first finger equal or shorter than second, and all marked with narrow fringes of skin; nuptial pads on first fingers of males; broad webbing reaching tips of all toes; dorsum skin smooth with weak dorsolateral fold.

Remarks.

Odorrana hosii was ubiquitous at the rocky sections of streams with many boulders. All individuals were collected at night but specimens could be observed in the day hiding in the roots of large trees at the stream bank.
