New records of species distribution help advance our understanding of species biogeographical dynamics and, potentially, local adaptations. Here, we report for the first time the presence of the Mediterranean house gecko (Hemidactylus turcicus) on a small, isolated Aegean island from which only one other reptile species has been previously documented. This discovery contributes new distribution data, enriching future assessments of both the species and its habitat.

Little is known about fire as an agent of direct animal mortality, and specifically, there is controversy regarding the effects of fire on reptiles. In the Sierra Morelos natural protected area in Mexico, both unplanned (e.g., man-made illegal and accidental burns) and prescribed burns occur during the dry season. In this study, we assessed direct fire-induced reptile mortality in the Sierra Morelos natural protected area by comparing live and dead individuals. Of the 14 reptile species reported in the area, seven were found dead due to fire. One-third of the individuals found in 2021 (34% of 169 ind.) and 2022 (33% of 33 ind.) were killed by fire. The mean density of detected dead individuals was 1.60 ± 2.99 individuals/ha in 2021 and 0.31 ± 0.27 individuals/ha in 2022. Mortality densities were similar in areas subjected to prescribed burns and in areas affected by unplanned burns (W= 37.5, p = 0.4383). Since our survey likely underestimated the actual mortality caused by fire, our findings show the important direct impact of fire on the reptile community of the Sierra Morelos natural protected area and support the notion that anthropogenic fire can represent a serious risk for reptiles in fragile ecosystems.

We present information on the occurrence of colubrid vine snakes (Oxybelis) and dipsadid sharpnose snakes (Xenoxybelis) from the lowlands of Bolivia. These genera have been poorly reported from Bolivia and information presented herein includes nine new record provincials from the departments of Beni, Cochabamba, La Paz, Pando, and Santa Cruz, Bolivia. Moreover, we present the first records of Oxybelis inkaterra Jadin, Jowers, Orlofske, Duellman, Blair & Murphy, 2021 from Bolivia and we extend the known range of this species by approximately 207 km (Río Sipia, La Paz) and 628 km (Campamento Guacharos, Cochabamba) southeast of the type locality (Puerto Maldonado, Peru) in South America. In addition, we present morphometric information, meristic characters, coloration pattern, ecological aspects and natural history for the three species of vine snakes (O. aeneus, O. fulgidus, O. inkaterra) and two species of sharpnose snakes (X. argenteus, X. boulengeri) from the Bolivian lowlands.

Insular organisms typically evolve in closed, isolated systems; thus, changes caused by introduced species can drastically affect their ecology. Isle Royale National Park (Michigan, USA) is a remote island in Lake Superior that, until relatively recently, was void of earthworms. Its two native natricine snakes are known to feed on earthworms on the mainland; here, we confirm that eastern gartersnakes (Thamnophis sirtalis) are also feeding on earthworms on Isle Royale. It is unknown how this new important dietary source will impact the snake ecology on Isle Royale.

Achalinus sheni Ma, Xu, Qi, Wang, Tang, Huang & Jiang, 2023 was originally described based on only male specimens from Lianyuan City and Nanyue District, Hunan, China. So far, no information on the females of this species is available. After molecular systematics and morphological characters of recently collected specimens from Xinshao County, Hunan, several specimens (3 males and 1 female) were identified as this species. Therefore, we provided supplementary descriptions of the female characteristics of this species in this study. Meanwhile, we extended the description of this species.

Distinguishing between anthropogenic introductions and natural colonizations can be complex, especially in groups that are evidently both capable natural colonizers and anthropophilic, such as some geckos of the genus Hemidactylus. However, such information is fundamental both for constructing appropriate conservation approaches, as well as to identify biogeographical patterns. Here we assessed the origins and taxonomic status of the Hemidactylus geckos found on the Îles Éparses, disjunct small islands of the western Indian Ocean located around Madagascar, using partial mitochondrial DNA sequences. Hemidactylus platycephalus was confirmed on Juan de Nova, presumed introduced from continental Africa. The H. mabouia-mercatorius complex was identified on Juan de Nova, Europa, Tromelin, and Grande Glorieuse, with H. mabouia (sensu stricto) on Juan de Nova and H. mercatorius on Europa, from where it is likely to have been introduced to Tromelin. An unnamed lineage within H. mercatorius, previously known only from the Aldabra Islands, was identified on Grande Glorieuse, and further demonstrated the unexpectedly high genetic diversity within this lineage.
区分人为引入和自然定殖可能很复杂，尤其是对于那些显然既能自然定殖又嗜人类的类群，如半齿壁虎属的一些壁虎。然而，这些信息对于构建适当的保护方法以及识别生物地理模式都是至关重要的。在这里，我们利用部分线粒体DNA序列评估了在马达加斯加周围的西印度洋小岛（Îles Éparses）上发现的半爪壁虎的起源和分类地位。在新胡安岛（Juan de Nova）上确认了半爪蟾蜍（Hemidactylus platycephalus），推测它们是从非洲大陆引进的。在新胡安岛、欧罗巴岛、特罗姆林岛和格朗德格洛里厄斯岛发现了马布亚-梅卡托里斯半齿龙复合体，其中新胡安岛发现了马布亚半齿龙（严格意义上的），欧罗巴岛发现了梅卡托里斯半齿龙，它很可能是从那里传入特罗姆林岛的。在大格洛里厄斯岛发现了 H. mercatorius 的一个未命名品系，该品系以前只在阿尔达布拉群岛出现过。

Melanophryniscus fulvoguttatus is a small toad that inhabits the Cerrado, Atlantic Forest, and humid Chaco of South America. Due to its aposematic coloration and behavior, it is a species that may present chemical defenses such as alkaloids and a restricted diet similar to other species of the genus. Although it was described in the early 20th century, there is still little information on its natural history and ecology. Here, we described the diet, tested the sexual dimorphism, and calculated the fertility index of M. fulvoguttatus based on a sample of eight males and 21 females from a population within the Cerrado. Sexual dimorphism was assessed using 15 morphometric measures; diet was calculated as an index of relative importance by prey item and tested for sex differences; fertility was tested for relations between body size and the number of eggs; and we also estimated the reproductive investment. Our results demonstrate that this population’s diet consisted mostly of ant species, with Pheidole radoszkowskii being the most important, followed by Crematogaster sp. and Cyphomyrmex transversus. Regarding sexual dimorphism, we observed that females were significantly larger than males, with a positive relationship between female size and the number of eggs. We did not find significant differences in the diets of males and females. Although the diet and reproductive aspects of M. fulvoguttatus are similar to those of its congeneric species, further studies are needed in order to address the relationship between the species diet and its chemical defenses.

The Napo Treefrog Rhacophorus napoensis was described based on five male specimens from Napo County, Baise City, Guangxi Autonomous Region, China. Herein, we report on new findings and a range extension of this species based on an examination of preserved specimens collected from Bac Giang and Nghe An provinces, Vietnam. Futhermore, molecular analyses of specimens Rhacophorus spp. previously identified as R. rhodopus that were reported in Bac Giang, Nghe An as well as Thanh Hoa, and Ha Tinh provinces based on mitochondrial DNA supported the morphological findings. The Vietnam specimens have a pairwise divergence of less than 2% from those of the type series of Rhacophorus napoensis (based on the 16s rRNA mtDNA gene). Based on the new information, we confirm the presence of R. napoensis in Vietnam and update the diagnostic characters of this species and distribution. We suggest the species should be considered as of Least Concern (LC) following the IUCN’s Red List categories. Further studies reassessing the populations of the Rhacophorus bipunctatus complex are required.

The Paddy frog species Micryletta hekouensis was described based on only two specimens from Nanxi Village, Nanxi Town, Hekou County, Honghe Prefecture, Yunnan Province, China. Herein, we report on new findings and a range extension of this species based on a re-examination of preserved specimens deposited in Duy Tan University (DTU) and Zoological Museum of Lomonosov Moscow State University (ZMMU) collected from Vietnam. All new specimens were previously identified as Micryletta cf. inornata or M. cf. steinegeri. Molecular analyses based on mitochondrial DNA supported the morphological findings. The newly identified specimens have a pairwise divergence of only 0.7% from those of the type series of M. hekouensis, based on the 16s rRNA mtDNA gene. Based on the new information, we confirm the presence of M. hekouensis in Vietnam and update the diagnostic characters of this species and its distribution. We suggest the species should be considered as Near Threatened (NT) following the IUCN’s Red List categories. Further studies reassessing the populations of the Micryletta inornata complex in the Indochinese Region (including Vietnam, Laos, Cambodia, and Thailand) are required.
河口稻田蛙（Micryletta hekouensis）是根据中国云南省红河州河口县南溪镇南溪村的两个标本描述的。在此，我们重新研究了保存在 Duy Tan 大学（DTU）和莫斯科国立大学罗蒙诺索夫动物学博物馆（ZMMU）的标本，并在此基础上报告了该物种的新发现和分布区扩展情况。所有新标本之前都被鉴定为 Micryletta cf. inornata 或 M. cf. steinegeri。基于线粒体 DNA 的分子分析支持了形态学研究结果。根据 16s rRNA mtDNA 基因，新鉴定的标本与 M. hekouensis 的模式系列标本的成对差异仅为 0.7%。基于这些新信息，我们确认了越南存在M. hekouensis，并更新了该物种的诊断特征及其分布。根据世界自然保护联盟红色名录的分类，我们建议将该物种视为近危物种（NT）。需要进一步研究，重新评估印度支那地区（包括越南、老挝、柬埔寨和泰国）的Micryletta inornata复合种群。

Current knowledge of the vertical distribution of Triturus macedonicus places the species at altitudes up to 2140 m. Herein, we report its presence in the alpine lake Gistova at 2360 m on Mt. Grammos, Greece, thus extending the highest altitudinal point for the species, as well as for the Triturus genus. This record showcases the adaptive capacity of the Macedonian newt, which allows it to occupy markedly different environments. More populations may exist at similar or even higher altitudes and their discovery could positively impact conservation efforts.
