ResumoTwo 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.
