BACKGROUND
The Hekou Torrent Frog () was recently discovered from southern China and northern Vietnam in 2022. The knowledge about natural history and feeding ecology of this species is virtually lacking.
NEW INFORMATION
Based on our recent fieldwork in northern Vietnam, we report a new population of from Ha Giang Province. In this study, we provide novel data on the diet of , based on stomach content analyses of 36 individuals (17 males and 19 females). A total of 36 prey categories with 529 items, comprising 515 items of invertebrates and 14 unidentified items, were found in the stomachs of . The dominant prey items of the species were Hymenoptera (Formicidae), Orthoptera (Acrididae), Lepidoptera (Lepidoptera other), Mantodea (Mantidae) and Araneae. The importance index (Ix) of prey categories ranged from 7.1% to 11.5%. Hymenoptera (Formicidae) had the highest frequency of prey items, found in 36 stomachs.
背景
河口湍蛙于2022年最近在中国南部和越南北部被发现。关于该物种自然史和食性生态的知识几乎空白。
新信息
基于我们近期在越南北部的野外工作，我们报告了来自河江省的一个新的河口湍蛙种群。在本研究中，我们基于对36个个体（17只雄性和19只雌性）的胃内容物分析，提供了关于河口湍蛙食性的新数据。在河口湍蛙的胃中总共发现了36类猎物，共529个猎物个体，其中包括515个无脊椎动物个体和14个无法鉴定的个体。该物种的主要猎物种类为膜翅目（蚁科）、直翅目（蝗科）、鳞翅目（其他鳞翅目）、螳螂目（螳螂科）和蜘蛛目。猎物种类的重要性指数（Ix）在7.1%至11.5%之间。膜翅目（蚁科）的猎物个体出现频率最高，在36个胃中均有发现。
