This paper reports for the first time the presence of Aethina tumida Murray, 1867 in hives of Apis mellifera Linnaeus, 1758, established in the locality of Pucnachen Municipality of Calkini the State of Campeche, México. Nitidulids were collected manually on the honey combs in the frames of A. mellifera hives, defecating on honey and on the floor of the hives, fermenting honey making it useless. A. tumida is a potential pest in beekeeping due to direct damage caused to honey as a food product, causing significant economic losses for beekeepers of this region of México. Also, the presence of this beetle was verified for the first time in stingless bee colonies, which are of great importance in traditional honey production. A detailed morphological description of the beetle is provided.

本文首次报道了1867 年Aethina tumida Murray 在Apis mellifera Linnaeus 的蜂巢中的存在，Linnaeus 于 1758 年在墨西哥坎佩切州卡尔基尼的 Pucnachen 市建立。Nitidulids 是在A. mellifera蜂箱框架中的蜂巢上手动收集的，它们在蜂蜜和蜂箱地板上排便，发酵蜂蜜使其无用。A. tumida由于对作为食品的蜂蜜造成直接损害，因此是养蜂业的潜在害虫，给墨西哥该地区的养蜂人造成重大经济损失。此外，这种甲虫的存在首次在无刺蜂群中得到证实，这在传统蜂蜜生产中非常重要。提供了甲虫的详细形态描述。
