We report the first occurrence of partial xanthism in Notopterus synurus (Bloch and Schneider 1801), collected from West Bengal, India, in May 2018. The specimen has yellow colouration on the dorsal portion, head and fins, except for a white ventral region, melanophores on the pectoral fin base and black eyes.
