Types	Holotype: VNUF (originally as VFU) R.2014.14, adult male, collected by Vinh Quang Luu and Thidtavanh Suliyavong on 20 June 2014. Paratypes. Two adult males NUOL R-2015.3, IEBR A.2015.33 and one adult female VFU R.2014.16, the same data as the holotype.
Diagnosis	Diagnosis: Gekko sengchanthavongi sp. nov. can be distinguished from its congeners in the Gekko japonicus group by a combination of the following characters: a medium-sized gecko species (SVL 67.7–77.3 mm); nares in contact with rostral; internasals absent; postmentals enlarged; supralabials 8–10; infralabials 6 or 7; dorsal tubercles absent; ventral scale rows from mental to cloacal slit 175–184; scale rows around midbody 120–135; ventral scale rows 35–43; webbing weakly developed between fingers and toes; tubercles on dorsal surface of limbs and tail absent; precloacal pores 3+1 or 3+2 in the males, separated from each other by one poreless scales, absent in the female; postcloacal tubercles 2/2; subcaudals enlarged; dorsum with dark bars.
Comment	Abundance: only known from its original description (Meiri et al. 2017).
Etymology	We name the new species in honour of Mr. Sinnasone Sengchanthavong, Natural Resources and Environment Department of Khammouane Province, Laos, in recognition of his great support of our field research in Hin Nam No NPA.
