Abstract

Background: The odd-scaled snake genus Achalinus, which is widely distributed in northern Vietnam, China and Japan, is a poorly-known group of snakes. Numerous species within this genus have been described based on few specimens or only a single type specimen. Achalinushunanensis Ma, Shi, Xiang, Shu & Jiang, 2023 was described based on only two male specimens from Huaihua City and Changsha City, Hunan Province, China. To date, this species has only been recorded in Hunan Province and the information on females is not available. During our herpetological surveys in 2024, two Achalinus specimens were collected from Guizhou Province, China. We compared morphology and mitochondrial DNA sequence data of these two specimens with all the species of the genus Achalinus. Both datasets strongly supported classification of the adult female specimen from Dushan County to A.hunanensis and the adult male specimen from Xifeng County to A.yunkaiensis.

New information: In this study, we describe the first female specimen of A.hunanensis in detail and provide revised diagnoses of this species based on newly-collected and examined specimens and update the distribution of A.hunanensis and A.yunkaiensis.

首次描述了Achalinushunanensis Ma， Shi, Xiang, Shu & Jiang, 2023（蛇形目，Xenodermidae）的雌性和形态变异，并扩展了该物种和A.yunkaiensis Wang, Li & Wang, 2019。

背景：奇鳞蛇属Achalinus广泛分布于越南北部、中国和日本，是一种鲜为人知的蛇类。本属内的许多种已根据少数标本或仅一个模式标本被描述。对湖南省怀化市和长沙市的Achalinushunanensis Ma， Shi, Xiang, Shu & Jiang， 2023进行了描述。迄今为止，该物种仅在湖南省有记录，雌性资料不详。我们在2024年的爬行动物调查中，在贵州省采集了2个阿卡林纳斯（Achalinus）标本。我们将这两个标本的形态和线粒体DNA序列数据与所有阿卡林纳斯属的物种进行了比较。这两组数据都有力地支持了独山县至湖南古猿的成年雌性标本和西峰县至云开古猿的成年雄性标本的分类。新信息：本研究详细描述了湖南古猿的第一个雌性标本，并根据新采集和检验的标本对该物种进行了修正诊断，更新了湖南古猿和云开古猿的分布。

期刊介绍： Biodiversity Data Journal (BDJ) is a community peer-reviewed, open-access, comprehensive online platform, designed to accelerate publishing, dissemination and sharing of biodiversity-related data of any kind. All structural elements of the articles – text, morphological descriptions, occurrences, data tables, etc. – will be treated and stored as DATA, in accordance with the Data Publishing Policies and Guidelines of Pensoft Publishers. The journal will publish papers in biodiversity science containing taxonomic, floristic/faunistic, morphological, genomic, phylogenetic, ecological or environmental data on any taxon of any geological age from any part of the world with no lower or upper limit to manuscript size.
