中国无色裸藻类的新分类单位

NEW TAXA OF COLOURLESS EUGLENOIDS FROM CHINA

于1975—1985年，相继在湖北、湖南、云南和陕西等省进行淡水藻类标本的采集，然后进行裸藻门分类学研究，发现了裸藻类的新分类单位．它们是无色裸藻类中2个属的10个新种类：隶属于变胞藻属（Astasia）的有5个新种和1个新变种，即梭形变胞藻（A.acus）、棒形变胞藻（A.claviformis）、纺锤变胞漠（A.fusiformis）、梨形变胞藻（A.pyriformis）、矩形变胞藻（A.rectangularis）和膨大变胞藻粗壮变种（A.inflatavar.crassa）；隶属于瓣胞藻属（Petalomonas）的有2个新种和2个新变种，即短尾瓣胞藻（P.brevicauda）、斜沟瓣胞藻（Pobliqussulcus）、内卷瓣胞藻卵形变种（P.involutavarovata）和瓣胞藻不对称变种（P.mediocanellatavar．asymmetrica）。模式标本存放在中国科学院水生生物研究所淡水藻类标本室．

During 1975-1985, specimens of freshwater algas were collected from Hubei, Hunan, Yunnan and Shanxi Provinces in China. In a study on algal taxonomy, many new taxa of euglenoids are found. Ten new taxa of colouress euglenoids are repoded in this WL Among these, five new species and one new variehes belong to Astasia (i. e. they are A. acus, A. claviformis, A fusuformis, A. Pyriformis, A rectangularis and A. inflata var. crassa); two new species and two new varieties belong to Petalomonas (i. e. P brevicauda, P obliquisulcus, P involuta var. ovata and P. mediocanellata varasymmetrica). Their holotypes and paratypes are preserved in the 'Herbarium of Institite Hydrobiology,The Chinese Academy of Sciences'.
