A new acanthoecid choanoflagellate species, Acanthocorbis mongolica sp. nov. was found in preserved phytoplankton samples from the freshwater lake Bayan Nuur (Uvs Nuur Basin, NW Mongolia) in concentrations of up to 1.8×10(5)cellsL(-1). It is the first well-documented species of the mainly marine order Acanthoecida to be found in a freshwater lake. The lorica structures were studied with scanning electron microscopy. Key morphological features of the vase-shaped lorica are spine bases that are composed of multiple (2-4) parallel costal strips, and the existence of two transverse costae. The ecological implications of this find are discussed.
一种新的刺冠盘虫（Acanthocorbis mongolica sp. nov.）在蒙古乌布苏湖（Uvs Nuur 盆地，西北蒙古）的淡水浮游植物样品中被发现，其浓度高达 1.8×10(5)cellsL(-1)。这是首次在淡水中发现的主要海洋刺冠盘虫目中有详细记录的物种。通过扫描电子显微镜研究了外壳结构。花瓶形外壳的关键形态特征是由多个（2-4）平行肋条组成的刺基部，以及存在两条横向肋条。讨论了这一发现的生态意义。
