  • 摘要: 美洲龟甲轮虫Keratella americana Carlin,1943年被认为主要分布在美洲地区,但陆续报告在其他地区有出现。2015年在对华南地区浮游动物调查时发现,星云湖、抚仙湖、百色水库及飞来峡水库中均出现该种类。检测了广西百色水库中龟甲轮虫的COⅠ序列,与已知美洲龟甲轮虫序列相似度高达98%。中国该龟甲轮虫种群与墨西哥美洲龟甲轮虫种群间差异度为2%,进一步确定为美洲龟甲轮虫。文章描述了美洲龟甲轮虫形态及生境,使用扫描电镜法比较了美洲龟甲轮虫、螺形龟甲轮虫Keratella cochlearis(Gosse,1851)、热带龟甲轮虫Keratella tropica(Apstein,1907)及无棘龟甲轮虫Keratella tecta(Gosse,1851)的咀嚼器。美洲龟甲轮虫主要特点为:背甲长度远大于宽度,侧中棘刺短于侧棘刺,背甲中央最后一个板块未封闭,向后棘刺延伸。4种龟甲轮虫咀嚼器主要区别在于砧基的形状,美洲龟甲轮虫砧基比其他3种轮虫发达,螺形龟甲轮虫砧基似“T”形,热带龟甲轮虫砧基为扇形,无棘龟甲轮虫平直。种间的砧基存在明显差异,可作为热带地区龟甲轮属的分类依据。
    Abstract: Keratella americana Carlin, 1943 mainly distributes in the America, and it had also been found in other continents. When we investigated zooplankton in South China in 2015, the species was found in Xingyun Lake, Fuxian Lake, Baise Reservoir and Feilaixia Reservoir. Its mitochondrial cytochrome oxidase subunitⅠ(COⅠ) gene was sequenced and showed a similarity of 98% with the sequences from GenBank, and this confirmed the species as K. ame-ricana. In the present study, a description was given of K. americana. Its trophi were compared with these of three common species:Keratella cochlearis (Gosse, 1851), Keratella tropica (Apstein, 1907) and Keratella tecta (Gosse, 1851), using a scanning electron microscope. K. americana is characterized by the following features:width of lorica narrower than its length; intermediate spines shorter than lateral spines; last facet in dorsal plate polygonal, open. The trophi of the four species differ in the shape of the fulcrum:The fulcrum of K. americana is stronger than the other three species. K. cochlearis has a T-shaped fulcrum and that of K. tropica is fan-shaped. The fulcrum of K. tecta is straight. The fulcrum therefore appears to significantly differ in shape and can be used for taxonomy and identification of diffe-rent Keratella.
