在对云南省拉市海高原湿地/自然保护区硅藻生物多样性调查中，发现一种异丝藻新种。新物种类似于Gomphonema acuminatum复合体的成员，具有独特的轮廓，其中瓣膜的肿胀中心与头杆一样宽或更宽。瓣裂的膨胀的中间部分比在本种组中的其他类群更向两极延伸。我们描述了新分类群的形态特征的基础上，光镜和扫描电镜观察。这是中国云南异鞭藻属一新种的另一报道，最近在该种复合体中也描述了一个新分类群。
During an investigation of the diatom biodiversity of Yunnan Province, one new Gomphonema species was observed from a plateau wetland / nature reserve area associated with Lashi Lake. The new species resembles members of the Gomphonema acuminatum complex, possessing a distinctive outline where the tumid center of the valve is as wide or wider than the headpole. The swollen middle portion of the valve extends more towards both poles than in other taxa in this species group. We describe the morphological features of the new taxon based on LM and SEM observations. This is another report of a new Gomphonema species from Yunnan Province, China; recently a new taxon in this species complex was also described from this Province.
