Body condition is an important indicator in many ecological studies since it is expected that individuals and populations perform better in habitats more suitable for species. A wide range of metrics have been proposed as condition indices. In this study, we estimated the phenotypic condition of water frog species using the residual condition index. The study was carried out in three localities adjacent to nature preserves in South Banat, Serbia and with different levels of preserved natural features and anthropogenic pressure. Selected localities are typical habitats of water frogs with two parental and their hemiclonal hybrid species present. The localities were scored for suitability of the aquatic and terrestrial habitats. Statistical significance of residual condition index patterns from a multiway ANOVA was obtained for locality but not for species and sex. The lowest condition index was observed in frogs sampled from a locality maintained by human activity and with the lowest habitat suitability. Furthermore, the highest body condition index was obtained on the locality with the highest habitat suitability. One of the parental species, P. ridibundus had the highest overall body condition index while the hybrid species (P. esculentus) had the lowest. None of the three species from the complex had the highest body condition in all three localities, nor the worst.

A new species of the Cyrtodactylus chauquangensis species group is described from Yunnan Province, China, based on morphological and molecular data. The new species closely resembles C. wayakonei morphologically, but can be separated from the latter by having more white rings on original tail, more lamellae under finger IV and toe IV, less longitudinal ventral scale rows, and enlarged femoral scales. However, the new species is closely related to C. martini rather than C. wayakonei genetically. The new species differs from C. martini by genetic distance of 3.3% and from investigated other members of the C. chauquangensis species group by genetic distances of 6.4 – 17.8% in the COI gene.
根据形态学和分子学数据，描述了中国云南省的Cyrtodactylus chauquangensis种群的一个新种。新种在形态上与C. wayakonei极为相似，但由于其尾部有更多的白色环纹、第IV指和第IV趾下有更多的片状鳞片、腹部鳞片纵行较少以及股鳞片增大，因此可与后者区分开来。不过，从遗传学上看，新种与 C. martini 而不是 C. wayakonei 关系密切。在 COI 基因上，新种与 C. martini 的遗传距离相差 3.3%，与调查的 C. chauquangensis 种群其他成员的遗传距离相差 6.4 - 17.8%。

To investigate morphological traits of the poorly known Zarudny’s tortoise, Testudo graeca zarudnyi Nikolsky, 1896, which has only been reported from Iran so far, we have conducted morphometric analysis to test sexual differences (sexual size and shape dimorphism, SSD) in Marvar Prohibited Hunting Area (central Iran). Our findings showed that males have wider carapace and larger hind limbs; while, females have longer plastron. This pattern has resulted in shape differences with males; that is, have more domed and wider carapace than to the females. Generally, Females are larger than males we will discuss it as a force to fecundity selection. The results showed that this subspecies does not follow Rench’s rule which argues that males are larger than females.
扎鲁德尼陆龟（Testudo graeca zarudnyi Nikolsky，1896 年）是一种鲜为人知的陆龟，目前仅在伊朗有报道，为了研究这种陆龟的形态特征，我们在马尔瓦尔禁猎区（伊朗中部）对其进行了形态计量分析，以检验其性别差异（性大小和性形状二态性，SSD）。我们的研究结果表明，雄性的甲壳更宽，后肢更大；而雌性的甲壳更长。这种模式导致了雄鱼的形状差异，即雄鱼的躯干比雌鱼更圆、更宽。一般来说，雌性比雄性大，我们将把它作为繁殖力选择的一种力量来讨论。研究结果表明，该亚种并不遵循伦奇规则（Rench's rule），该规则认为雄性比雌性大。

At the end of May, a permanent spawning site of Onychodactylus fischeri was first discovered in the gravel-stony layer under the bottom of a small river valley in the upward flows of subsurface alluvial waters (upper reaches of the Pravaya Sokolovka River, the Sikhote-Alin Range, Chuguevka rayon, Primorsky Krai). This place was located at an altitude of 650 m a.s.l. in mixed coniferous-broad-leaved forest in a narrow river valley. The primary spawning site lay beneath the bottom of a small water body that was two meters away from the main river course. The water in the breeding ground was slightly acidic and slightly mineralized. The local population of O. fischeri begins to reproduce in the end of May, when the water temperature inside the site reaches 6.1 – 7.9°C. This site had been used for egg laying on multiple occasions. We found 72 clutches attached to several small stones (n = 11). There were no large cavities between the stones, only narrow gaps. There were two recently laid clutches, 26 clutches in the late stages of embryogenesis, already empty sacs and fragments of old mucous stalks. O. fischeri lays paired egg sacs measuring 35.4 ± 1.9 mm (34.5 – 38.15; n = 3) in length. Egg arrangement in clutches of O. fischeri was varying: in one (or in two) rows in both sacs, or in one row — in one sac and in two — in the other. The mean number of eggs in each sac was 6.8 ± 1.3 (4 – 10; n = 55), the mean number of eggs in the clutch — 13.6 ± 2.2 (9 – 17; n = 27), the egg diameter — 8.08 ± 0.6 mm (6.71 – 8.9; n = 19). For the first time we recorded the otter (Lutra lutra) actively hunting adult O. fischeri. In late May – early July it preyed upon salamanders near the spawning site. The otter ate heads and bodies of O. fischeri but not tails. Perhaps, a high concentration of muciparous glands with poisonous secretion in the tails prevented the predator from eating them.

Although Rhacophorus orlovi from China was once sampled in previous phylogenetic studies, up to now it has never been formally included in any list of Chinese amphibians, which could lead to a misunderstanding that R. orlovi has no accurate distribution in China. Here, we describe R. orlovi for the first time from China based on one specimen collected from Yunnan Province and compare it with the holotype of the species. Molecular evidence supports it belonging to R. orlovi and genetic divergence within R. orlovi ranges from 0 to 1.85%. Compared to the holotype, the specimen from Hekou, Yunnan, China shows some variations in both morphometric characters and color pattern.

Cuora amboinensis is considered to be the most wide-ranging member of its genus and has one of the widest distributions of all geoemydid turtle species. The range of Cuora amboinensis spans major biogeographic barriers and encompasses diverse habitats. The genetics (nuDNA and mtDNA) and morphometry of 288 Cuora amboinensis sensu lato (s.l.) specimens from across its range were analyzed, and we identified five divergent species-level clades and two subspecies-level clades. One of the two identified potential subspecies lacked reliable locality data, requiring further field research before taxonomic steps can be undertaken. We designate a neotype for Cuora amboinensis sensu stricto and elevate both Cuora amboinensis couro and Cuora amboinensis lineata to species-level taxa. In addition, we describe two new species and one new subspecies from the «Cuora amboinensis» complex. The wide distribution of Cuora amboinensis s.l. is problematic because it is indigenous to many Pacific and Indian Ocean islands. We sought to clarify plausible dispersal hypotheses across islands using phylogeographic analyses.

The Indochinese Peninsula represents one of the key global biodiversity hotspots in Southeast Asia. The herpetofauna of Indochina (herein including Vietnam, Laos, Cambodia, and Thailand) currently (as by 10 August 2023) comprises 882 native and six invasive species of reptiles and is one of the richest in the world. About 40% of the Indochinese reptile species were discovered or recorded within the first two decades of the 21st century. We review the literature and our field data to assess all recent discoveries and taxonomic changes; we compile an annotated checklist of reptilian fauna of Indochina, including updated faunal lists for Vietnam and Thailand. Reptile species checklists for Laos and Cambodia are published for the first time. For each species we provide the following information: scientific name; recommended common name in English; information on type specimens; information on recognized subspecies; type locality; data on its distribution within Indochina and beyond; IUCN conservation status; taxonomic comments and the most important references. We review the distribution of each reptilian species across the 23 biogeographic subregions of Indochina, estimate the similarity among the regional faunas and evaluate their species richness and endemism. In total, we record 882 native reptile species belonging to three orders, 34 families and 163 genera; of them 408 species (46.3%) are endemic to Indochina. Comprising 512 known species, the reptilian fauna of Thailand is the richest (114 country endemics, 22.3%), followed by Vietnam with 496 species (157 endemics, 31.7%), Laos with 250 species (39 endemics, 15.6%), and Cambodia with 191 species (15 endemics, 7.9%). A cluster analysis of faunal similarity between the subregions revealed three major groupings, corresponding to the Sundaland fauna south of the Isthmus of Kra, the subtropical fauna of northeastern Indochina, and the tropical fauna of mainland Indochina. Within the latter grouping four clusters can be distinguished: (1) northern, central and southern Annamites, (2) western Indochinese subregions, (3) central-south Vietnam lowlands including the Bolaven Plateau and Cardamom Mountains, (4) and the depleted faunas of river deltas, coastal areas and offshore islands. We identify the Northern, Central and Southern Annamites, the Northwest Uplands of Vietnam, Laos and Thailand, Southern Tenasserim in Thailand as the major centers of reptilian diversity in Indochina. The highest number of Indochinese endemic reptilian species was recorded in Central-Southern Vietnam Lowlands, Northern Annamites, and Central Annamites. The analysis of reptilian distribution patterns suggests the presence of 20 clusters of species sharing similar distribution patterns across Indochina. Our results further underline the key role of Indochina as an important area for diversity and conservation of reptiles. Among 882 native species of Indochinese reptiles, 356 species (40.4%) are considered as Data Deficient

For each species we provide the following information: scientific name; recommended common name in English; information on type specimens; information on recognized subspecies; type locality; data on its distribution within Indochina and beyond; IUCN conservation status; taxonomic comments and the most important references. We review the distribution of each reptilian species across the 23 biogeographic subregions of Indochina, estimate the similarity among the regional faunas and evaluate their species richness and endemism. In total, we record 882 native reptile species belonging to three orders, 34 families and 163 genera; of them 408 species (46.3%) are endemic to Indochina. Comprising 512 known species, the reptilian fauna of Thailand is the richest (114 country endemics, 22.3%), followed by Vietnam with 496 species (157 endemics, 31.7%), Laos with 250 species (39 endemics, 15.6%), and Cambodia with 191 species (15 endemics, 7.9%). A cluster analysis of faunal similarity between the subregions revealed three major groupings, corresponding to the Sundaland fauna south of the Isthmus of Kra, the subtropical fauna of northeastern Indochina, and the tropical fauna of mainland Indochina. Within the latter grouping four clusters can be distinguished: (1) northern, central and southern Annamites, (2) western Indochinese subregions, (3) central-south Vietnam lowlands including the Bolaven Plateau and Cardamom Mountains, (4) and the depleted faunas of river deltas, coastal areas and offshore islands. We identify the Northern, Central and Southern Annamites, the Northwest Uplands of Vietnam, Laos and Thailand, Southern Tenasserim in Thailand as the major centers of reptilian diversity in Indochina. The highest number of Indochinese endemic reptilian species was recorded in Central-Southern Vietnam Lowlands, Northern Annamites, and Central Annamites. The analysis of reptilian distribution patterns suggests the presence of 20 clusters of species sharing similar distribution patterns across Indochina. Our results further underline the key role of Indochina as an important area for diversity and conservation of reptiles. Among 882 native species of Indochinese reptiles, 356 species (40.4%) are considered as Data Deficient","PeriodicalId":48693,"journal":{"name":"Russian Journal of Herpetology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135252210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new species of rock lizards of the genus Darevskia Arribas, 1999 — Darevskia arribasi sp. nov. is described from vicinity of Ertso Lake in South Ossetia. In comparison of Darevskia arribasi sp. nov. with other species of the «saxicola-brauneri» complex [D. lindholmi (Szczerbak, 1962), D. saxicola (Eversmann, 1834), D. brauneri (Mehely, 1909) (including D. b. brauneri, D. b. myusserica Doronin, 2011, D. b. darevskyi (Szczerbak, 1962), and D. szczerbaki (Lukina, 1963)], the new species is characterized by the smallest body size among all representatives of this complex L♂♂ — 55 – 62 mm; ♀♀ — 58 – 63 mm. The number of scales around the middle of the body (Sq.) in D. arribasi sp. nov. (52 – 58, more often 54 – 56) also significantly less than for D. saxicola sensu lato in generally. Along the throat from ear to ear fold there are 36 – 42 scales, less than in D. saxicola sensu lato. Two large preanal shields present in front of the anal shield in half of the individuals examined; in a quarter of individuals on both sides of the small central preanal there are by one enlarged lateral preanal shield, in another quarter all preanal shields are of the same size. Central temporal (Massetericum) always developed; always six pair of mandibulars, three in contact; collar straight, extremely rarely slightly serrated; ribs on the caudal scales are expressed to some extent; rostral usually separated from frontonasal by nasal shields. The coloration of adult males is olive-lettuce, or olive-brown from above; adult females are grey-brown; juvenile coloration coffee-brown with the blue and black spots on the edge of the outer ventral shields at the middle of trunk. Taxonomical status of new species is well supported with result of analysis of the mitochondrial cytochrome b data.
