Abstract

BACKGROUND

The White-lipped Treefrog Yu, Hui, Hou, Wu, Rao & Yang, 2019 was previously confused with (Blyth, 1852). Records of from Yunnan (China), Vietnam and Thailand were recognised as a misidentification and this taxon was subsequently described as a new species, based on morphological and molecular evidence. This species is currently known from southern China, Thailand, Laos and Vietnam. However, knowledge about its natural history and feeding ecology is virtually lacking.

NEW INFORMATION

We herein report a newly-discovered population of from Lang Son Province, northern Vietnam. In addition, we provide novel data about the diet of , based on stomach content analyses of 38 individuals (37 males and one female). A total of 26 prey categories with 681 items were found in the stomachs of . The dominant prey items of the species were Orthoptera (Acrididae, Tettigoniidae), Coleoptera (Languriida, Leiodidae, larvae, other Coleoptera), Mantodea (Mantidae) and Blattodea (Blaberidae, Blattidae, other Blattodea). Coleoptera (Coccinellidae, Cupedidae, Elateridae, Languriidae Leiodidae, Tenebrionidae, larvae and other Coleoptera) was the category with the highest frequency of prey items, found in 24 stomachs. The most important (IRI) groups amongst the prey of were Coleoptera (24.52%) and followed by Orthoptera (24.43%), Blattodea (9.12%), Mantidae (8.14%) and Hemiptera (4.05%).

摘要

背景

白唇树蛙（Yu, Hui, Hou, Wu, Rao & Yang, 2019）曾被误认为是（Blyth, 1852）。来自中国云南、越南和泰国的该物种记录被认为是错误鉴定，随后基于形态学和分子证据将这个分类单元描述为一个新物种。该物种目前分布于中国南部、泰国、老挝和越南。然而，关于其自然历史和食性生态的知识几乎空白。

新信息

我们在此报告在越南北部谅山省新发现的一群白唇树蛙。此外，我们基于对38个个体（37只雄性和1只雌性）的胃内容物分析，提供了关于白唇树蛙食性的新数据。在白唇树蛙的胃中总共发现了26个猎物类别，包含681个猎物个体。该物种的主要猎物为直翅目（蝗科、螽斯科）、鞘翅目（长蠹科、葬甲科、幼虫、其他鞘翅目）、螳螂目（螳螂科）和蜚蠊目（硕蠊科、蜚蠊科、其他蜚蠊目）。鞘翅目（瓢虫科、长扁甲科、叩头甲科、长蠹科、葬甲科、拟步甲科、幼虫和其他鞘翅目）是猎物个体出现频率最高的类别，在24个胃中被发现。白唇树蛙猎物中最重要的（相对重要性指数）类群是鞘翅目（24.52%），其次是直翅目（24.43%）、蜚蠊目（9.12%）、螳螂科（8.14%）和半翅目（4.05%）。
