Despite the applied importance of necrophilous histerid beetles, their communities and habitat preferences had not been characterized in the Iberian Peninsula. The current article describes the composition of those communities in seven types of natural habitats along a bioclimatical gradient in central Spain, describing and discussing the habitat preferences and niche breadths of the most abundant species. In total, 25 species of necrophilous Histeridae were collected using carrion-baited traps. As a result, six groups of species can be distinguished according to their habitat preferences. These groupings depend on either the distribution among habitats or their restriction to certain habitats. Moreover, within each habitat, the type of vegetation was a factor structuring histerid communities, with those species with wide distribution throughout several habitats showing a preference for more open areas.
尽管嗜尸阎甲科甲虫具有应用重要性，但其群落和栖息地偏好尚未在伊比利亚半岛得到描述。本文描述了西班牙中部沿生物气候梯度的七种自然栖息地中这些群落的组成，描述并讨论了最丰富物种的栖息地偏好和生态位宽度。使用腐肉诱饵陷阱共收集到25种嗜尸阎甲科甲虫。结果，根据其栖息地偏好可区分出六组物种。这些分组取决于栖息地之间的分布情况或对某些栖息地的限制。此外，在每个栖息地内，植被类型是构建阎甲科群落的一个因素，那些在多个栖息地广泛分布的物种表现出对更开阔区域的偏好。
