Two new diatom taxa belonging to the genus Stauroneis Ehrenberg were discovered from an aerophilic habitat in Sikkim, India, a part of the Eastern Himalayas. The morphology of Stauroneis sikkimensis sp. nov. and Stauroneis lepchae sp. nov. are illustrated with light and scanning electron micrographs and compared with similar species in the genus. S. sikkimensis is characterised by lanceolate valves with a median constriction, bluntly rounded apices, radiate striae, and a H-shaped stauros. S. lepchae has broadly elliptical to lanceolate valves with obtusely rounded apices, radiate striae, and a characteristic bow-tie shaped stauros. These are the first two diatom species described from the Eastern Himalayas of India.

从喜马拉雅山脉东部的印度锡金一个有氧的生境中发现了两个属于Stauroneis Ehrenberg属的硅藻类群。锡金斯氏金藻的形态。年11月。和Stauroneis lepchae sp。年11月。用光和扫描电子显微照片进行说明，并与该属中的相似物种进行比较。锡金链球菌的特征是具有正中部收缩的披针形瓣，钝圆形的顶端，放射状的纹状体和H形星形。沙丁鱼具有宽椭圆形到披针形的瓣膜，具有钝角的圆形顶端，放射状的条纹和典型的领结状星形。这是从印度喜马拉雅山脉东部描述的头两个硅藻物种。
