Bumblebees (Bombus spp.) are important pollinators of agricultural crops and wild plants, especially tomato and sweet pepper species requiring large-sized and buzzing pollinators. The endoparasitic mite Locustacarus buchneri Stammer 1951 (Acari; Podapolipidae) was identified from commercial populations of the introduced European bumblebee Bombus terrestris. We report the genus and species of this mite for the first time in Koran fauna. Identification was based on morphological and molecular characteristics. Morphological details were illustrated and compared with those to the original description. We analyzed partial cytochrome oxidase I gene to understand the phylogenetic relationship and possible source of invention. The maximum likelihood tree and haplotype network revealed that the Korean population is closely related to Japanese population than European population. The ecological significance of this finding and possible consequences of the invasive species to the native species are discussed.

大黄蜂（Bombus spp。）是农作物和野生植物的重要授粉媒介，特别是需要大型且嗡嗡作响的授粉媒介的番茄和甜椒品种。从引入的欧洲大黄蜂Bombus terrestris的商业种群中鉴定出内寄生螨Locustacarus buchneri Stammer 1951（Acari； Podapolipidae）。我们首次在古兰经动物群中报告了这种螨的属和种。鉴定基于形态和分子特征。说明了形态学细节，并将其与原始描述进行了比较。我们分析了部分细胞色素氧化酶I基因，以了解系统发生关系和可能的发明来源。最大似然树和单倍型网络显示，与欧洲人口相比，韩国人口与日本人口密切相关。讨论了这一发现的生态意义以及入侵物种对本地物种的可能后果。
