In India, the butterfly is found along the Himalayas from Sikkim to Assam and eastwards to south Myanmar. It also has been recorded from the Andaman islands.[2][4]

The type locality is Bengal.[2]

Status

It is considered by William Harry Evans to be very rare in Hong Kong, rare in South India, but not rare in the Himalayas.[4]

Cilia of hindwing orange yellow. Underside paler suffused with orange yellow; forewing with a curved series of pale purple narrow streaks between the veins before the apex, and a broad pale buff patch along the posterior margin; hindwing with the veins and lines between them and cilia orange yellow: a black orange yellow encircled basal spot on both wings; a discal series of pale purplish streaks. Third joint of palpi brown; palpi beneath, front and sides of thorax, legs and streak alongside of abdomen orange yellow; middle of thorax and abdomen and anal tuft orange yellow.

Vane-Wright and de Jong (2003) (see TOL web pages on genus Bibasis and genus Burara in the Tree of Life Web Project) state that Bibasis contains just three diurnal species, the crepuscular remainder having been removed to Burara. The species now shifted to Burara are morphologically and behaviorally distinct from Bibasis, within which many authors have formerly included them.
