. We analysed the status and distribution of the Sage Skipper Muschampia proto (Ochsenheimer, 1808), a rather rare and local Hesperiidae species at the edge of its range in the north-western part of the Balkan peninsula, mainly Croatia and Bosnia & Herzegovina. In order to determine the species’ presence in the region, we mapped the occurrence of its hostplant, Jerusalem Sage Phlomis fruticosa Linnaeus (Lamiaceae). We also summarized all the available knowledge on M. proto in the Balkan Peninsula and provided a literature overview for each country this species has been recorded in so far. In Croatia, the distribution of M. proto is very limited and is located only in the wider surroundings of Dubrovnik city. In the present paper, we also provide the first and only record of M. proto in Bosnia & Herzegovina, from a single locality close to the Croatian border in the Dubrovnik area. Due to its limited distribution in both countries, we propose that the conservation status of the species should be changed from none to vulnerable.

Sage Skipper Muschampia proto（Ochsenheimer，1808）（鳞翅目，Hesperiidae）在西北巴尔干地区的分布范围之内的分布和地位

。我们分析了鼠尾草原先鼠（Ochsenheimer，1808年）的现状和分布情况，鼠尾草原鼠是在巴尔干半岛西北部（主要是克罗地亚和波斯尼亚和黑塞哥维那）其边缘范围内的一种相当稀有的本地蛇蛛科物种。为了确定该物种在该地区的存在，我们绘制了其寄主植物耶路撒冷鼠尾草Phrutis fruticosa Linnaeus（唇形科）的位置。我们还总结了巴尔干半岛所有关于原生质支原体的知识，并提供了迄今为止已记录该物种的每个国家的文献综述。在克罗地亚，原始M. proto的分布非常有限，仅位于杜布罗夫尼克市更广阔的环境中。在本文中，我们还提供了波斯尼亚和黑塞哥维那原产M. proto的第一个记录，也是唯一记录，来自杜布罗夫尼克地区克罗地亚边境附近的一个地方。由于其在两个国家的分布有限，我们建议将该物种的保护状况从无改变为脆弱。
