A new species of Iguanidae Liolaemini lizard from the San Guillermo National Park in western Argentina, is described. The new species is a member of the Liolaemus darwinii complex within the monophyletic boulengeri species group. It is distinguished by its small body size, relatively long tail, low number of scales around midbody, dorsal scales moderately keeled, precloacal pores only in male, bulged patch of enlarged scales on the proximal posterior surface of the thigh in both sexes, dorsal pattern lacking of light vertebral or dorsolateral stripes, antehumeral fold without black pigment in female but greyish in male, a prescapular dark dot dorsal to antehumeral fold in both sexes, and postscapular spot absent. The new species is terrestrial, living in habitats with gravel and sandy soil in an Andean Monte landscape with sparse vegetation, above 2270 meters of altitude.

A new species of Iguanidae Liolaeminae from the Parque Nacional San Guillermo, San Juan province in western Argentina, is described. The new species is member of the Liolaemus darwinii complex within the monophyletic boulengeri species group. It is characterized by small body size, long tail, relatively low number of scales around midbody, dorsal scales keeled, precloacal pores only in male, bulged patch of enlarged scales on the proximal posterior surface of the thigh in both sexes, and a dorsal color pattern in the male of 12–13 pairs of dark paravertebral spots and irregularly scattered light blue and white scales “speckled” on reddish brown ground. Both sexes lack of light vertebral or dorsolateral stripes. Liolaemus sp. nov. is terrestrial, dwelling on rocky gravel and sandy soil in a Monte landscape with sparse vegetation, and seems to have low population density.

A new species of Lepidophyma from the Biosphere Reserve area of Tehuacan-Cuicatlan, Oaxaca, Mexico, is described. This new species, Lepidophyma cuicateca sp. nov., is known from two areas in the Cuicatlan Valley. Lepidophyma cuicateca sp. nov. is a member of the Lepidophyma gaigeae species Group and is characterized by its small body size, small size of tubercular body scales, poorly differentiated caudal whorls and interwhorls, and relatively large dorsal, ventral and gular scales. It lives in shady places, below rocks along the Apoala River, and is commonly found in plantain, sapodilla, cherimoya, mango and coffee plantations, as well as tropical deciduous forest. The description of L. cuicateca sp. nov. increases the number of species in the L. gaigeae Group to five.

We sampled two forms of Leptobrachium in syntopy at the type locality of L. pullum at upper elevations on the Langbian Plateau, southern Vietnam. The two forms differed in morphology (primarily in coloration), mitochondrial DNA, and male advertisement calls. One form closely agrees with the type series of L. pullum (but not to its original description due to error), and the other is described as new. Leptobrachium leucops sp. nov. is distinguished from its congeners by having small body size (males with SVL 38.8–45.2), the upper one-third to one-half of iris white, a blue scleral arc, a dark venter, and sexually active males without spines on the upper lip. Leptobrachium pullum and L. mouhoti, a recently described species from low-elevation slopes of the Langbian Plateau in eastern Cambodia, are morphologically divergent but genetically similar, warranting further investigation into geographic variation in the red-eyed Leptobrachium of southern Indochina.

A new species of the genus Cyrtodactylus is described from Dien Bien Province, northwestern Vietnam based on morphological and molecular data. Cyrtodactylus ngati sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 69.3 mm; dorsal pattern consisting of six dark irregular transverse bands between limb insertions; inter-supranasals one; dorsal tubercles present on occiput, body, hind limbs and on first half of tail; 17–22 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, with interspersed tubercles; 32–38 ventral scales between ventrolateral folds; 13 precloacal pores separated by a diastema of 5/5 poreless scales from a series of 7/7 femoral pores in enlarged femoral scales; precloacal and femoral pores absent in females; 1–3 postcloacal tubercles on each side; transversely enlarged median subcaudal scales absent. In the molecular analyses, the new species is shown to be the sister taxon to C. interdigitalis from Thailand. This is the 47th species of the genus Cyrtodactylus and the first member of the C. brevipalmatus species group recorded from Vietnam.

A new scincid lizard, Plestiodon takarai sp. nov., is described from the Senkaku Group, Ryukyu Archipelago, Japan. The Plestiodon lizards in this island group have previously been identified as P. elegans because they all exhibit a patch of enlarged and irregularly arranged scales on the posterior surface of their femurs. However, detailed molecular analyses revealed that the Senkaku population, although closely related to P. elegans and other species in the P. latiscutatus species group, is substantially diverged from all other recognized species. Furthermore, although the Senkaku population largely exhibits the characteristic morphological features of this species group, it can be differentiated from all recognized species by the scutellation and hatchling tail coloration. The biogeographical and conservation implications of these findings are briefly discussed.

In this paper we describe Potamophylax qafshtamaensis sp. n., a new species of the Potamophylax winneguthi species group, from Qafështamë National Park in Albania. The new species belongs to the Potamophylax tagas species cluster and is most close to Potamophylax hajlos Oláh, 2012 and Potamophylax alsos Oláh, 2014. Potamophylax qafshtamaensis sp. n.  differs from all known species of the P. tagas species cluster by its unique shape of aedeagus. It also differs from its most similar congeners mainly in exhibiting differently shaped inferior appendages and parameres in males, as well as setose sternite IX and the dorsal unsetose plate of the anal tube in female.The new species is microendemic of Qafështamë National Park and is the fifth known species of the Potamophylax tagas species cluster, which is distributed in Albania and Macedonia.

A new species of Cnemaspis Strauch, 1887 is described from Nilgala Savannah Forest in Sri Lanka. The new species is diagnosed from all other congeners by the following suite of characters: small body size (SVL< 33 mm), dorsal scales on trunk homogeneous, one pair of post mentals separated by a single small chin scale, ventral scales on trunk smooth, subimbricate, 17–19 scales across the belly. Subdigitals scansors smooth, entire, unnotched; lamellae under digit IV of pes 17 –18. Males with femoral pores on each thigh but lacking precloacal pores. Median row of subcaudals smooth, subimbricate, enlarged and in an irregular series of subhexagonal scales. This new species had been previously confused with Cnemaspis alwisi Wickramasinghe & Munidradasa, 2007. The new species differs from Cnemaspis alwisi by having 122–129 ventral scales (versus 146–152), 7–8 supralabials (versus 8–10), and relatively shorter SVL ranging between 31.5–32.9 mm (versus 37.8–39.9 mm). Further, the new species is genetically divergent from Cnemaspis alwisi, the species that it closely resembles by 13.5% and 7.8% from its sister species in the ND2 gene. The present discovery highlights the need for dedicated herpetofaunal explorations in Sri Lanka, especially the intermediate bioclimatic zone and associated cave systems and rock outcrops.

A new species of the genus Cyrtodactylus from Vientiane Province, northern Laos is described based on morphological and molecular data. Cyrtodactylus muangfuangensis sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 83.9 mm; dorsal pattern consisting of dark nuchal loop, nape band and five dark transversal bands between limb insertions; intersupranasals two; dorsal tubercles present on occiput, body, hind limbs and tail base; 15 or 16 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, without interspersed tubercles; 31–37 ventral scales between ventrolateral folds; six precloacal pores and 15 femoral pores in males, which are interrupted by six to eight poreless scales; six precloacal pitted scales plus in total 10–15 pitted femoral scales in females, which are separated by six to eight poreless scales; enlarged precloacal and femoral scales present; two or three postcloacal tubercles; median subcaudal scales transversely enlarged. In molecular analyses, the new species is strongly supported as a member of the Cyrtodactylus phongnhakebangensis species group, and weakly corroborated as a sister taxon to C. pageli. Pairwise genetic comparison shows that it is at least 18% divergent from other congeners in the species group based on a fragment of the mitochondrial cytochrome C oxidase subunit I gene.

We describe a new Pristimantis from La Libertad and Rumiloma, Reserva Mazar, Andes of Southeastern Ecuador, at elevations between 2895–3415 m. This species is assigned to the P. orestes group, from whose members it differs by its small body size (adult males ≤ 18.1 mm; adult females ≤ 23.7 mm), usually reticulated ventral pattern, and visible tympanum. The vocalization of the new species consists of a series of calls; each call is composed by a pulsed, non-modulated note in frequency, and with a dominant frequency of 3122–3171 Hz. A molecular phylogeny based on a fragment of the mitochondrial gene 12S shows that the new species is sister to Pristimantis simonbolivari.

A new species, Folsomia wanxianensis, from China (Chongqing) was described in the present paper. The new species shares some characters with F. albens Kaprus’ & Potapov 1999, such as the absence of ommatidia, sensillar formulae and small body size. However, it could be easily distinguished from F. albens by the number of laterodistal setae on the ventral tube and the number of setae on furca. It is also easily distinguished from all known species in the genus by the combination of the following characters: 4+4 laterodistal setae on the ventral tube, 10+10 dorsal setae on manubrium, 10–11 ventral and four dorsal setae on dens, and other features.
