摘要:

本文对我国沿海岸采集的褐藻门（Phaeopyta）短毛藻科（Elachistaceae）短毛藻属（Elachista Duby）海藻进行了分类学研究。发现2个新种，即长海短毛藻E.changhaiensis Luan et Ding sp.nov.和暗色短毛藻E.fusca Luan et Ding sp.nov.。文中对此2个种的形态特征进行了较详细的特征描述，并对新种提供了相应的英语特征描述，以及较完整的其他分类学信息，与相似种进行了比较。长海短毛藻藻体黄褐色，长同化丝直径7~22 μm，多室囊长95~150 μm，由23~38个小室组成；短同化丝长200~350 μm，由11~24个细胞组成。暗色短毛藻藻体暗褐色，长同化丝直径8~14 μm，多室囊分枝，长75~150 μm，由27~39个小室组成；短同化丝着生于长同化丝的基部，长0.13~0.33 mm，由5~13个细胞组成。模式标本保存在中国科学院海洋研究所海洋生物标本馆（AST）。

Abstract:

The specimens of genus Elachista in family Elachistaceae were investigated from Chinese coasts. Two new species were identified, viz. E. changhaiensis Luan et Ding sp.nov. and E. fusca Luan et Ding sp.nov.. The taxonomic characteristics of these species were described in detail with other data referring to species classification. E. changhaiensis Luan et Ding sp.nov. is yellow brown, and has long assimilating filaments with 7-22 μm in diameter, plurangia with 95-150 μm long and 23-38 chambers, and short assimilating filaments with 200-350 μm long and 11-24 cells. E. fusca Luan et Ding sp.nov. is dark brown, and has long assimilating filaments with 8-14 μm in diameter, plurangia branched with 75-150 μm long and 27-39 chambers, and short assimilating filaments born from the base of long assimilating filaments with 0.13-0.33 mm long and 5-13 cells. Holotypes were preserved in the Marine Biological Herbarium, the Institute of Oceanology, Chinese Academy of Sciences (AST).
