Scalation of the typeseries of  Hemiphyllodactylus kiziriani sp. nov.from Luang Prabang Province, Laos.   Etymology.We name the new species in honour of Dr. David A. Kizirian, American Museum of Natural History (New York, USA), in recognition of his contribution to herpetological research in the Indochina region. Ascommon names we suggest Kizirian’s Slender Gecko (English), Kizirians Halbblattfingergecko ( German), and Thạch sùng dẹp ki-zi-ri-an (Vietnamese).  Natural history.  Hemiphyllodactylus kizirianiinhabits disturbed secondary limestone forests near a residential area at elevations between 590 and  640 m.Specimens were found at night on tree bark and limestone cliffs near cave entrances or on a limestone boulder near a forest path, ca. 0.2–1.2 mabove the ground. Two female paratypes(IEBR A.2014.5, NUOL R-2014.2) were gravid with two shelled eggs each.   Distribution.The species is currently known only from Luang Prabang Province in northern Laos( Fig. 4).
