S. chalakkudiensis can be told apart from S. denisonii by possession of an inferior mouth (vs. subterminal) and presence of a black marking in the dorsal-fin (vs. absence), and the scarlet body stripe being duller and terminating beneath or anterior to the dorsal-fin origin (vs. brighter and terminating beneath the centre of the dorsal-fin).
