摘要：

报道了横断山区异极藻属（Gomphonema）硅藻中国新记录18种，分别为：缠结异极藻头端变种（G. intricatum var. capitata Hustedt）、变窄异极藻（G. angustius Reichardt）、非洲异极藻（G. afrhombicum Reichardt）、假中间异极藻（G. pseudointermedium Reichardt）、尖顶型异极藻（G. auguriforme Levkov）、加利福尼亚异极藻（G. californicum Stancheva & Kociolek）、近拉蒂科尔异极藻（G. sublaticollum Reichardt）、球顶异极藻（G. sphenovertex Lange-Bertalot & Reichardt）、威尔斯科异极藻（G. wiltschkorum Lange-Bertalot）、瓦尔达异极藻（G. vardarense Reichardt）、微小异极藻（G. parvuliforme Lange-Bertalot）、细小异极藻（G. parvuloides Cholnoky）、维多利亚异极藻（G. lacus-victoriensis Reichardt）、尤卡塔尼异极藻（G. yucatanense Metzeltin & Lange-Bertalot）、窄头异极藻（G. angusticephalum Reichardt & Lange-Bertalot）、长贝尔塔异极藻（G. lange-bertalotii Reichardt）、中间异极藻（G. intermedium Hustedt）和中亚异极藻（G. medioasiae Metzeltin, Lange-Bertalot & Nergui）。本研究对新记录种的形态特征进行了详细描述，给出了每个种的地理分布、生境信息和理化指标，并对新记录种及其相似种的形态特征进行了讨论。

This paper reports 18 new records of diatoms from the genus Gomphonema in the Hengduan Mountains of China, including G. intricatum var. capitata Hustedt, G. angustius Reichardt, G. afrhombicum Reichardt, G. pseudointermedium Reichardt, G. auguriforme Levkov, G. californicum Stancheva & Kociolek, G. sublaticollum Reichardt, G. sphenovertex Lange-Bertalot & Reichardt, G. wiltschkorum Lange-Bertalot, G. vardarense Reichardt, G. parvuliforme Lange-Bertalot, G. parvuloides Cholnoky, G. lacus-victoriensis Reichardt, G. yucatanense Metzeltin & Lange-Bertalot, G. angusticephalum Reichardt & Lange-Bertalot, G. lange-bertalotii Reichardt, G. intermedium Hustedt, and G. medioasiae Metzeltin, Lange-Bertalot & Nergui. Detailed descriptions of the morphological characteristics, geographical distribution, habitat preferences, and physicochemical indices for each species are provided. Furthermore, comparative analyses of the morphological characteristics of the newly recorded species and their closely related counterparts are discussed.
