DistributionVietnam (Lam Dong)

Type locality: Near Giang Ly Ranger Station (12o 10.954’N, 108o 40.805’E, at an elevation of 1442 m a.s.l.), Bidoup - Nui Ba National Park, Da Chai Commune, Lac Duong District, Lam Dong Province, the Central Highlands of Vietnam.  
Reproduction 
TypesHolotype: IEBR R.4830, adult male, collected on 10 May 2015 by K.V. Nguyen.
Paratypes: Three specimens collected from the same locality as the holotype: IEBR R.4831, IEBR R.4832, adult males, IEBR R.4833, adult female; the same collection data as for the holotype. 
DiagnosisDiagnosis: The new species from southern Vietnam differs from the remaining congeners of the genus Hemiphyllodactylus by a combination of the following characters: a bisexual taxon; a maximum SVL of 45.9 mm; dorsal scale rows 16; ventral scale rows 8 or 9; chin scales 7–10; postmental scales enlarged; femoral and precloacal pores in a continuous series, 23–25 in total in males, absent in the female; digital lamellae formula 4-5-5/6-5 forefoot) and 5-6-6-6/5 (hind foot); cloacal spurs 2 or 3 on each side in both males and female; enlarged subcaudal scales absent; dorsal trunk pattern with two paravertebral stripes, formed by two rows of dark spots; dark lateral head stripe distinct; postsacral mark cream or orange and bearing anteriorly projecting arms (Do et al. 2021).
