本文报道了采自加拿大的针藻科一新种--少质体Haramonaspauciplastidasp. nov.。Haramonas的模式种是Haramonas dimorpha，目前已知的只有两个种。这种新的真菌属于该属，因为它在细胞的后端具有管状内陷，产生大量的粘液，并在其生命周期中产生运动和非运动阶段。少质体哈氏藻的叶绿体颜色为黄绿色，与绿色Haramonasviridis Horiguchi et Hoppenrath相似。 然而，这种植物与该属其他物种的不同之处在于它拥有较少的叶绿体，很少重叠。超微结构的研究表明，这两个物种之间的差异，在片层中的类囊体的数量，分散的蛋白核基质的存在下，和plastapelluli的位置。小亚基核糖体RNA基因的系统发育分析表明，三个物种可以从遗传上相互区分，他们形成了一个强大的分支，在针藻。这一结果支持的概念，Haramonas的特征是synapomorphies。这是Haramonas物种分子数据的第一份报告。
A new species of the Raphidophyceae, Haramonas pauciplastida sp. nov. from Canada is described. The genus Haramonas has been described based on the type species Haramonas dimorpha and currently only two species are known. This new alga belongs to the genus because it possesses a tubular invagination at the posterior end of the cell, producing a large amount of mucilage and generating both motile and non‐motile phases in its life cycle. The chloroplast color of H. pauciplastida is yellowish green, and is similar to that of Haramonas viridis Horiguchi et Hoppenrath. However, this alga differs from the other species of the genus in that it possesses fewer chloroplasts, which are rarely overlapping. The ultrastructual study shows differences between these two species in the number of thylakoids in the lamella, the presence of a scattered pyrenoid matrix, and the position of the plastoglobuli. The phylogenetic analyses of the small subunit ribosomal RNA gene from the Haramonas species reveal that three species can be distinguished genetically from each other and they form a robust clade in the Raphidophyceae. This result supports the notion that the characteristic features of Haramonas are synapomorphies. This is the first report of molecular data from the Haramonas species.
