Callerebia dibangensis was recently described from a single specimen collected in 1987 from Upper Dibang Valley, Arunachal Pradesh along with comparison of wing morphology of this single male individual with the congeners.  However, there is no other information on the species.  The current study recorded a large number of live individuals of such a species around Mayodia pass and was thus able to note the variations in wing morphology, the wing morphology of the female, distinguishing features between the sexes, observations on biology and ecology of C. dibangensis from Mayodia pass (1,900–2,265 m) in lower Dibang Valley, Arunachal Pradesh, India along with comparison of male genitalia of C. dibangensis with its closest ally C. scanda opima from the same locality.
