A new species of Cyrtodactylus (Squamata: Gekkonidae) from the karst forest of northern Laos
We describe a new species of the gekkonid genus Cyrtodactylus on the basis of two specimens collected from limestone forests of Luang Prabang Province, northern Laos. Morphologically, the new species is distinguishable from its congeners by a combination of the following diagnostic characters: maximum SVL 86.1 mm; supralabials 9 or 10; infralabials 7-9; dorsal tubercles in 15 or 16 rows at midbody; ventral scale rows 34-36 at midbody; precloacal groove absent; femoral scales not distinctly enlarged; precloacal pores absent in females (unknown in males); subdigital lamellae under the fourth finger 18 or 19, under the fourth toe 18-20; subcaudals not transversally enlarged; dorsal bands white, 4 or 5 between limb insertions plus another one between hind limbs; tail banded. Based on molecular analyses, the new species is clustered in the same clade with C. wayakonei and two other species from Luang Prabang and Houaphan provinces
A new species of Hemiphyllodactylus (Reptilia: Gekkonidae) from northern Laos
A new species of the genus Hemiphyllodactylus is described from Luang Prabang Province, northern Laos.

The new species is named in honour of Mr. Vilaphong Kanyasone, a staff of Provincial Natural Resources and Environmental Office of Luang Prabang Province, Laos, who collected the holotype and provided a great support for our field research in Laos. Ecological notes. Cyrtodactylus vilaphongi inhabits disturbed secondary limestone forest near a residential area at elevations between 577 and 597 m a.s.l. Specimens were found at night, on karst cliff and rock boulder ca. 0.5 m above the ground (Fig. 6). Air temperature at the site was 24–30 o C and humidity ranged from 72 to 86 %.Published as part of Schneider, Nicole, Nguyen, Truong Quang, Le, Minh Duc, Nophaseud, Liphone, Bonkowski, Michael & Ziegler, Thomas, 2014, A new species of Cyrtodactylus (Squamata: Gekkonidae) from the karst forest of northern Laos in Zootaxa 3835 (1), DOI: 10.11646/zootaxa.3835.1.4, http://zenodo.org/record/22461
