The rhodesgrass mealybug, Antonina graminis (Maskell, 1897), is reported for the first time from Chile, in the northern region of Tarapacá. This legless mealybug is widely distributed in tropical and subtropical regions around the world, and yet mentioned in the neighbouring countries. It feeds on a large variety of grasses (Poaceae), and can be considered as pest. The species identification was based on morphological and molecular data using the 28S gene as barcode marker. Of the five sites sampled, A. graminis was found in only one, indicating it may correspond to a recent introduction. Thus, it would be important to survey more closely its distribution within the country. A key to the genera of Pseudococcidae from Chile is provided, including relevant genera considered as pest, and not established in the country. This key is of direct interest to stakeholders in Chile, such as national phytosanitary services, and farm advisors.

罗丹草粉虱Antonina graminis（Maskell，1897），是塔拉帕卡北部地区的智利首次报道。这种无腿的粉虱在世界各地的热带和亚热带地区广泛分布，但在邻国却被提及。它以各种各样的草（禾本科）为食，可以被认为是害虫。物种鉴定是基于形态学和分子数据，使用28S基因作为条形码标记。在五个采样点中，A。graminis仅在一个中被发现，表明它可能对应于最近的介绍。因此，重要的是更仔细地调查其在国内的分布。提供了智利假球菌科的一个关键，包括被认为是有害生物且在该国未建立的相关属。智利国家利益植物检疫服务机构和农场顾问等利益相关者直接感兴趣。
