Abstract

Background: Microdaccus Schaum, 1864 and Psammodromius Peyerimhoff, 1927 are regarded as two closely-related taxa of Lebiinae, comprising a total of 11 species. The species known to date occur from south-eastern Europe and Egypt to Kazakhstan, Afghanistan and Iran.

New information: Microdaccus birgitae sp. nov. is described from the Hajar Mountains, Sultanate of Oman. Characterised by its slender pronotum with lateral margin almost not widened to hind angles and strongly rounded elytra, this species extends the known distribution range of the genus to the southern Arabian Peninsula. We studied taxonomically most of the Microdaccus and Psammodromius species, including some type material, re-assessing characters and rank Psammodromius Peyerimhoff, 1927 stat. nov. as a subgenus of Microdaccus Schaum, 1857. An illustrated key enables the identification of the known Microdaccus species.

Schaum Microdaccus Schaum， 1864：阿曼一新种，分类学注释及该属种的鉴定关键（鞘翅目，蠓科，Lebiinae）。

背景：Microdaccus Schaum（1864）和Psammodromius Peyerimhoff（1927）被认为是Lebiinae的两个近缘分类群，共有11种。目前已知的物种分布在欧洲东南部、埃及、哈萨克斯坦、阿富汗和伊朗。新资料：在阿曼苏丹国的哈贾尔山脉描述了布吉塔微蝇。其特点是其侧面边缘几乎没有扩大到后角的细长的前前额和强烈圆形的鞘翅，该物种将该属的已知分布范围扩展到阿拉伯半岛南部。本文对大部分小黄鸭属和沙黄鸭属进行了分类研究，包括一些类型资料，重新评价了Psammodromius Peyerimhoff， 1927 stat. 11 .作为Schaum小黄鸭属的一个亚属进行了分类。一个图示的钥匙使识别已知的Microdaccus物种。

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.
