A case of a successful incubation of a clutch of the European glass lizard (Pseudopus apodus) under controlled laboratory conditions during July 22 – September 19, 2019 is reported here. Fully developed neonates hatched from all eggs (n = 7) on the 60th day of incubation. A detailed description of the temperature and humidity regimes of incubation as well as the size and weight characteristics of eggs and offsprings are provided. Moreover, protecting and caring female behavior in regards to the clutch within the first month of incubation was documented comprehensively for the first time. Some aspects of P. apodus reproductive biology such as parental care, oviposition terms, frequency of reproduction and female fecundity are discussed taking into account the data accumulated within the last decennary for the Crimean populations of the species. Likely causes for the non-annual breeding of females were analyzed

On 26 June 2019, a large number of Suweon treefrogs, Dryophytes suweonensis, was found in a rice paddy located in Gimpo-si, South Korea. A total of 31 adults of D. suweonensis were found, breeding in a single rice paddy. No other Suweon treefrog was found within a radius of approximately 1 km from the rice paddy. The number of Suweon treefrogs recorded was much higher than in any other rice paddy. However, the reason for the large number of Suweon treefrogs gathering in only one rice paddy is unclear. Further studies on the areas where Suweon treefrogs have been found, and protection of the areas and the endangered species is recommended.

Two new species of the genus Acanthosaura Gray, 1831, previously identified as A. lepidogaster (Cuvier, 1829), are described from Yunnan Province, China, based on morphological and genetic data. The first new species from Jiangcheng County, southern Yunnan, is characterized by having very long tail in males and the second new species from most parts of southwestern Yunnan is characterized by having obvious bright red lips in males and fewer nuchal crest scales. Genetically, uncorrected sequence divergences of COI between the two new species and investigated congeners ranged from 5.5 to 21.6%.

In Montenegro, a herpetofaunal species richness has not translated into detailed ecological studies. An example is the marsh frog, one of the most common amphibians in Montenegro, which has insufficient information on its population and ecological structure, including feeding ecology. This study compared the morphological and ecological (diet, type of growth and condition) profiles of marsh frogs from two artificial lakes (Krupac and Slano) located in the central region of Montenegro. The comparison of morphometric ratios between localities revealed that two indices show the weak discrimination between populations. The dietary composition of the marsh frog, from studied artificial lakes, is similar to that of populations from natural habitats. Obtained results showed that marsh frogs from Lake Krupac have a higher growth rate than those from Lake Slano.

Westernmost population of the Snake-eyed Skink is found in Papuk, Croatia, and is the closest to the population from Ilok, Croatia. So far, the ecology of any of them has not been studied, and here, we document the variation between them. Furthermore, we estimated population density in Papuk using line transects, and quantitatively assessed its viability, i.e., chances for its survival under different scenarios; under current situation, with increased habitat, and with the negative effect of catastrophic events (e.g., forest fires, habitat degradation). Our study suggests that the climate between the two populations differs significantly, while other general requirements of the species remain the same in both locations. In the Papuk area we estimated the total population size from 5036 to 5483 individuals, with a relative density of 97 individuals per hectare. The population viability results suggest that the extinction of the Papuk population is likely to happen due to the negative trend in the number of individuals over 100 years. This implies that the population is not stable and under current condition shows the need for urgent conservation measures. We modeled two measures, 1) restoration of habitat via the removal of black pine plantations, and 2) translocation of the Snake-eyed Skink into two new habitats. Both methods rely on the increase of available habitat, and both were implemented in the study area. In 2014 an area of 900 m2 of black pine forest was removed, and in 2014 and 2016 we translocated 100 individuals per year (altogether 200 individuals) into new habitats. Monitoring data confirmed that the newly established subpopulations are present at both sites, and are reproducing, which could imply that our translocation might be successful.

Hitherto, body bending behavior (BBB) has been reported for less than a dozen of different snake species from tropical and subtropical America. Most authors assume that this rarely documented behavior is cryptic and antipredator, e.g., by taking the form of a liana the snake may avoid being attacked by a potential predator. We herein report the first records of this behavior in snakes in Asia and Europe. A dozen cases of body bending are documented for the colubrids Coelognathus radiatus (Boie, 1827), Ptyas carinata (Günther, 1858) and Oligodon joynsoni (Smith, 1917), and Malpolon monspessulanus (Hermann, 1804), and the natricids Fowlea piscator (Schneider, 1799) and Rhabdophis siamensis (Mell, 1931). In addition to the earlier reports from the New World, we suggest that BBB is widespread in snakes throughout the tropical and subtropical world. For a number of species that display it relatively frequently, such as C. radiatus in Thailand, BBB may have a significant adaptive value. We propose that this behavior is basically a kind of defensive immobility response that may develop swiftly or rather slowly and which is most often associated with diurnal activity, open spaces and an inclination to aggressive defenses. Our data suggest that its function is more often aposematic than cryptic.

The recent revision of the Ahaetulla nasuta complex in South Asia (India and Sri Lanka) resulted in a major modification of the systematics of this previously wide-ranging species. Ahaetulla nasuta sensu stricto is now endemic to Sri Lanka while other species inhabit Peninsular India. We here analyze the status of the nominal taxa including those considered synonyms of this species. Based on this analysis, we show that populations inhabiting the eastern part of the range of the former species Ahaetulla nasuta auctorum, namely Myanmar and the Indochinese Region, should be referred to Ahaetulla fusca (Duméril, Bibron et Duméril, 1854), a taxon we here resurrect from synonymy at species level. Its neotype is redescribed. We also discuss the status of populations inhabiting Myanmar. This first-phase revision sets the stage for regional workers to solve the taxonomy of the genus Ahaetulla based on fresh materials and collections across Myanmar and Indochina.
最近对南亚（印度和斯里兰卡）的Ahaeturla nasuta复合体进行了修订，对这一以前广泛存在的物种的系统学进行了重大修改。严格意义上的纳苏塔Ahaeturla nasuta现在是斯里兰卡的特有种，而其他物种则栖息在印度半岛。我们在这里分析了命名分类群的地位，包括那些被认为是该物种同义词的分类群。基于这一分析，我们表明，居住在前物种纳苏塔-auctorum范围东部的种群，即缅甸和印度支那地区，应被称为fusca（Duméril，Bibron et Dumériel，1854），这是我们在物种层面上从同义词中复活的一个分类单元。它的新类型被重新描述。我们还讨论了居住在缅甸的人口的状况。这一第一阶段的修订为地区工作者根据缅甸和中印的新鲜材料和收藏来解决Ahaetulla属的分类奠定了基础。

We describe a new species of the Rhacophorus genus, which differs from its congeners on the basis of a combination of the following morphological characters: (1) medium body size (SVL of adult female — 50.4 mm); (2) head slightly wider than long (HW/HL 1.01); (3) HW/SVL 0.35; (4) HL/SVL 0.35; (5) third finger disk diameter much smaller than tympanum diameter (FTD/TD 0.70); (6) tympanum large, the lower edge of the tympanic annulus almost reaches the edge of the upper lip (TJ/TD 0.27, TJ/OJ 0.48, TJ/NJ 0.39); (7) high ratio TD/ED 0.73; (8) ratio TFL/FLL2 1.62; (9) vomerine odontophores oblique, and widely separated, between choanae (gap is equal to the length of one odontophore), touching anterior edge of choanae, vomerine teeth well developed; (10) triangular calcar absent; (11) color pattern of dorsal surface of head, body, shoulders, forearms, thighs, and shanks looks like a cross-connection between adjacent channels, tubes, fibers and other parts of a network of two general kinds of color: of reddish-brown and beige with small sparsely arranged individual black spots; (12) ventral surfaces of belly, throat, chest, femur and all forelimbs light gray, on the throat, chest and femur pigmentation is somewhat much intensive; (13) belly, throat and chest are smooth; (14) pair of tubercles ventrolaterally from the cloacal opening absent; (15) iris is brown; (16) fingers-webbing formula: I2+ – 3II12/3 – 21/2III2+ – 2IV; (17) toes-webbing formula: I11/2 – 2II1 – 2+III1+ – 21/2IV2+ – 1+V. At present, Rhacophorus trangdinhensis sp. nov. is known only by a single specimen (female) from the type locality in an evergreen forest on limestone karst from 200 m a.s.l. elevation.
