A total number of 60 Diatoms belonging to 21 genera species are identified from Cauvery river at Bhavani region in Erode District, Tamil Nadu State and examined by using Light Microscopy (LM). The fresh water species Synedra ulna (Nitzsch) Ehrenberg and Synedra rumpen are recorded for the first time in the study area and abundant of epiphytic diatoms species. The Synedra ulna and Synedra rumpen species belonging to the genus Synedra are illustrious by tiny taxonomic features. The detailed morphology of the species Synedra ulna (Nitzsch) Ehrenberg and Synedra rumpen with the length and breadth of the valve, number of striae, shape of the apices, shape of the psedudoraphe and shape of the central area are examined.
