The objective of this work is to describe the taxa belonging to the genus Nitzschia encountered in the marine waters of Ngor (Senegal) and to propose a determination key. Observation of the samples collected between July 2009 and November 2011 has allowed to describe 7 taxa (Nitzschia coarctata, N. granulata, N. lorenziana, N. panduriformis, N. scalpelliformis, N. sigma, N. spathulata). A dichotomous determination key, based on morphological characters such as the shape of keels, frustules, valves and valves apices, has been proposed to facilitate their identification.
