摘要

在瑞典西海岸收集附生硅藻样本时，观察到一个小的Mastrogloia物种，与所描述的任何分类群都不匹配。光镜和电镜观察表明，该种为新种，隶属于乳舌亚科乳舌亚组。这个物种非常小，阀门长度不超过16.3微米。其特征是胸骨中缝两侧有窄的几乎直的中间凹陷，无边缘脊，瓣幔上有圆形乳晕，胸骨外侧完全透明。并与同类分类群作了比较。wulffii是一种中等数量的海洋物种，生长在广泛分布在瑞典Vrango岛沿岸的圆形红藻Polyides上。

Mastogloia wulffii, a new diatom (Bacillariophyceae) from the west coast of Sweden

While collecting epiphytic diatom samples from the west coast of Sweden, a small Mastrogloia species has been observed and could not be matched with any of the described taxa. Based on both light and electron microscopes examination, this species has been described as new, Mastogloia wulffii sp. nov. and included in Mastogloia section Sulcatae. This species is very small with valve length not exceeding 16.3 µm. It is characterized by having a narrow, almost straight median depression on both sides of the sternum-raphe, no marginal ridge and with rounded areolae on valve mantle as well as having completely hyaline lateral sterna. A comparison with similar taxa is given. M. wulffii is a marine species growing in moderate numbers on the red alga Polyides rotunda which is widely distributed along the coast of Vrango Island, Sweden.
