The Mexican free-tailed bat, Tadarida brasiliensis mexicana, is one of the most widely distributed bats, and its range includes the whole Mexican territory. Ectoparasites of this bat have been the subject of isolated reports, but no studies of its community ecology have been conducted. The acarine infracommunities associated with this bat were analyzed, comparing bat populations from three arid regions of Mexico: an abandoned factory in Nombre de Dios, Durango; a cave in Santiago, Nuevo León; and a church in Concepción del Oro, Zacatecas. The acarine infracommunity in Nuevo Le6n's bats exhibited the highest levels of diversity as reflected by a higher richness, a lower dominance, and a moderate and relatively homogeneous abundance in this locality in relation to the other two. This pattern is influenced by stable cave conditions relative to artificial habitats. Notwithstanding, further studies are required to determine whether or not different habitat conditions are a primary factor in the process of structuring the acari infracommunities.
墨西哥游离尾蝠（Tadarida brasiliensis mexicana）是分布最广泛的蝙蝠之一，其分布范围涵盖了整个墨西哥领土。关于这种蝙蝠的体外寄生虫已有一些孤立的报道，但尚未对其群落生态学进行研究。对与这种蝙蝠相关的螨类小群落进行了分析，比较了来自墨西哥三个干旱地区的蝙蝠种群：杜兰戈州Nombre de Dios的一座废弃工厂；新莱昂州圣地亚哥的一个洞穴；以及萨卡特卡斯州康塞普西翁德尔奥罗的一座教堂。新莱昂州蝙蝠身上的螨类小群落表现出最高的多样性水平，这体现在该地区相对于其他两个地区具有更高的丰富度、更低的优势度以及适度且相对均匀的丰度。这种模式受相对于人工栖息地而言稳定的洞穴条件影响。尽管如此，仍需要进一步研究以确定不同的栖息地条件是否是构建螨类小群落过程中的主要因素。
