The paucity of studies on Egyptian mongoose Herpestes ichneumon (Linnaeus, 1758) in Africa highlights the need for baseline information on the geographic range of this species as well as factors that may determine its distribution. This study presents eight novel locality records of H. ichneumon in Laikipia County, central Kenya, addresses questions on the species’ distribution in Africa, and predicts environmental (climatic) suitability across its range. From a total of 4,822 H. ichneumon occurrence records, we used 4,432 georeferenced records to generate distribution maps, conduct ecological niche modelling, and identify environmental limits for this species across its range with a focus on Africa. 20% of all records originate from continental Africa, including 121 records for Kenya. Despite extensive field research and predicted habitat suitability, H. ichneumon has not been previously reported in Laikipia County. Our niche models, however, predicted parts of Laikipia to be environmentally suitable for H. ichneumon. Similarly, our new distribution maps show extended geographic ranges both in Laikipia and Kenya as compared to the 2016 IUCN map. The eight Laikipia records underscore the limited knowledge for this species, its distribution, and its environmental requirements in Africa.

非洲埃及猫鼬Herpestes ichneumon(Linnaeus,1758)的生物地理学,肯尼亚中部莱基皮亚县的首次记录

在非洲缺乏对埃及猫鼬疱疹鱼的研究(Linnaeus,1758年),突出表明需要有关该物种地理范围以及可能决定其分布的因素的基线信息。这项研究提供了肯尼亚中部莱基皮亚县的八指鱼嗜血杆菌的新的本地记录,解决了非洲物种分布的问题,并预测了其范围内的环境(气候)适应性。从总共4,822 Hichichmon发生记录,我们使用了4,432个地理参考记录来生成分布图,进行生态位建模,并确定该物种在整个非洲范围内的环境极限,重点是非洲。所有记录中有20%来自非洲大陆,其中包括肯尼亚的121条记录。尽管进行了广泛的实地调研和预测的栖息地,H. ichneumon的以前未在莱基皮亚县报道。但是,我们的利基模型预测莱基匹亚虫的某些部分在环境上适合鱼腥藻。同样,与2016年世界自然保护联盟地图相比,我们的新分布图显示了莱基皮亚和肯尼亚的地理范围扩大。八种Laikipia记录强调了该物种的知识,分布及其在非洲的环境要求。
