Abstract

The Wroughton’s free-tailed bat (Otomops wroughtoni) is classified as Data Deficient under IUCN Red List due to inadequate information on its distribution, population, and ecology. The species was previously recorded from Belgaum district of Karnataka and from East Khasi Hills and Jaintia Hills districts of Meghalaya and from Cambodia, represented by a single specimen. Through our study on Chiroptera taxa across 19 Community Reserves between October 2021 and January 2022 using physical search, mist netting and acoustic study we have identified a new colony of O. wroughtoni from the Mikadogre village in South Garo Hills District of Meghalaya, which extends the current distribution to 135 km from the nearest known distribution site. Interestingly, unlike other known roosts of O. wroughtoni which are in large caves with high roofs and deep crevices or cupolas, this roost was in the open limestone cliff located next to a stream. In addition to this, we have also documented the breeding colony of the species from a previously known site at Pynurkba. This new finding emphasises that there are more potential roosts across the Northeast region of India with similar habitats and altitudes waiting to be identified.

印度梅加拉亚邦沃尔顿自由尾蝠（Otomops wroughtoni）（爬行动物门：蝠科）的新分布和繁殖记录

由于缺乏有关其分布、种群和生态学的资料，沃尔顿自由尾蝠（Otomops wroughtoni）在《世界自然保护联盟红色名录》中被列为数据不足物种。该物种曾在卡纳塔克邦的贝尔高姆地区、梅加拉亚邦的东卡西山区和詹蒂亚山区以及柬埔寨被记录，仅有一个标本。在2021年10月至2022年1月期间，我们使用物理搜索、雾网和声学研究等方法，对19个社区保护区的翼手目分类群进行了研究，在梅加拉亚邦南加罗山地区的米卡多格雷村发现了一个新的O. wroughtoni群落，这将目前的分布范围扩大到距离最近的已知分布地点135公里。有趣的是，不同于其他已知的疣鼻鳽栖息地，它们的栖息地都在有高屋顶、深裂缝或冲天炉的大型洞穴中，这个栖息地位于一条溪流旁边的开阔石灰岩悬崖上。除此之外，我们还记录了该物种在皮努尔克巴一个已知地点的繁殖地。这一新发现表明，在印度东北部地区，还有更多具有类似栖息地和海拔高度的潜在栖息地等待我们去发现。

期刊介绍： Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
