| 摘要: |
| 2011-2012年间对扎龙国家级自然保护区的藻类标本进行采集及观察鉴定.研究发现，该区域鼓藻类植物生物多样性较高，共观察到90个分类单位.研究过程中发现宽带鼓藻属的一个新种——Pleurotaenium parvulum Li，Fan&Wei.该物种特征为植物体单细胞，细胞小型，长圆柱形；半细胞顶端平截，其缘边横断面可见5个小结节；细胞壁平滑或具点纹；半细胞具两个轴生星状的色素体，每个色素体具1个蛋白核.本文比较了该物种与其相近种类之间的差异. |

| Abstract: |
| A very abundant desmids biota was found in Zhalong National Nature Reserve in 2011-2012,including 90 taxa in total.Among them,a Pleurotaenium species is proposed as new to science,Pleurotaenium parvulum Li,Fan&Wei.The new species is characterized of small cells and a long cylinder without processes,a truncated apex,five small nodules on cross section,cell wall smooth or with puncta,semicells with two axial longitudinal ridge-shaped chromatoplasts,and each with two pyrenoids.Differences between the species and allied taxa are discussed. |
