摘　　要：我国此前关于光薄甲藻GlenodiniumgymnodiniumPenard在西藏那错湖的记录是基于错误的鉴定,作者在相差显微镜下对标本进行了重新检查,发现此甲藻的细胞壁由多数甲片构成,甲片大小相似,多为六角形,应属于网甲藻属WoloszynskiaThompson的微小网甲藻W.tenuissima(Lauterborn)Thompson。中型四角甲藻TetradiniumintermediumGeitler采于武汉的一小池塘,附着于一鞘藻属Oedogonium植物的丝状体上,属于甲藻门中的不运动种类,营养时期不能运动。两个属种均为中国新记录。A re-examination under the phase contrast microscope of a collection made in a small lake in Xizang, China, which had been previously referred to Glenodinium gymnodinium Penard, has shown that the cell wall is composed of numerous usually hexagonal platelets, and thus the species should be a relatively common member of the genus Woloszynskia, namely W. tenuissima （Lauterborn） Thompson. Tetradinium intermedium Geitler is an immobile species collected from a small pond in Wuhan City, Hubei Province, China. It was attached on filaments of an Oedogonium species. Both genera are newly recorded in China.
