Abstract

Background: The Annam Stream Frog Hylaranaannamitica was recently discovered from north and central Vietnam and Laos by Sheridan and Stuart (2018). Knowledge of its natural history is virtually lacking.

New information: In this study, we provide an extended morphological description of Hylaranaannamitica, based on newly-collected specimens from Vu Quang National Park, Ha Tinh Province, Vietnam. In addition, we present data on the diet of Hylaranaannamitica, based on stomach content analyses of 46 individuals (32 males and 14 females) and compare prey selection between sexes. We found a total of 37 prey categories with 339 items, comprising 327 items of invertebrates, two items of vertebrates and 10 unidentified in the stomachs of H.annamitica. The most important (IRI) groups amongst the prey of H.annamitica were Coleoptera (17.19%), followed by Mantodea (14.78%), Orthoptera (11.26%), Lepidoptera (11.13%), Araneae (10.0%) and Blattodea (9.87%). There was an overlap of 45.63% in the diet between males and females and, in both sexes, the trophic spectrum was similar, predominantly consisting of Araneae, Coleoptera, Dermaptera, Diptera, Hemiptera, Hymenoptera, Isoptera, Lepidoptera, Mantodea and Orthoptera.

越南中部Hylaranaannamitica (Sheridan & Stuart, 2018)（两栖类：蛙科）的重新描述和饮食生态学。

背景：安南溪蛙Hylaranaannamitica是Sheridan和Stuart（2018）最近在越南北部和老挝中部发现的。人们对它的自然历史几乎一无所知。新资料：本研究基于在越南河亭省武光国家公园新采集的标本，对Hylaranaannamitica进行了扩展的形态描述。此外，作者还对46只海拉尔纳纳米亚虫（32只雄性，14只雌性）的胃内容物进行了分析，并比较了不同性别对猎物的选择。共发现37个猎物种类339个，其中无脊椎动物327个，脊椎动物2个，未知物种10个。棉蚜的主要捕食类群为鞘翅目（17.19%），其次为螳螂目（14.78%）、直翅目（11.26%）、鳞翅目（11.13%）、蜘蛛目（10.0%）和小蠊目（9.87%）。雌雄食性重叠率为45.63%，两性营养谱相似，主要由蜘蛛目、鞘翅目、皮翅目、双翅目、半翅目、膜翅目、等翅目、鳞翅目、曼托亚目和直翅目组成。

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.
