The present study aimed to document the freshwater microalgal diversity of the Scenedesmaceae family and their seasonal occurrence in Kothandaramar Temple Tank, West Mambalam, Chennai. The study recorded a total of 28 species belonging to 8 genera of microalgae. The seasonal variation of individual species was recorded from 2021 to 2023. Four seasonal patterns—winter, summer, monsoon, and post-monsoon—were observed throughout the two-year study period. Results revealed that Tetradesmus obliquus, Scenedesmus smithii var. linearis, Desmodesmus armatus var. longispina, and Pectinodesmus javanensis were reported in all four seasons of the study period. Based on Algaebase, the current names of 10 species from this family were reported for the first time in this study area.
