Mycalesis anaxias, the white-bar bushbrown, is a species of satyrid butterfly found in South and Southeast Asia. In South Asia, it inhabits Sikkim, eastwards through the hill-ranges to Assam, Cachar, Myanmar and Tenasserim. Also in southern India, in the Nilgiris and Travancore.

Description

Dry-season form

Wet-season form: male and female: Upperside dull Vandyke brown, paler in the female; subterminal and terminal fine lines on both forewings and hindwings fulvescent (tawny): cilia brown. Forewing with an oblique white preapical short band not quite reaching either the costa or the termen. Underside: forewing: basal area up to the white band, and in a transverse line from lower end of band to dorsum, blackish brown; terminal margin beyond broadly paler brown; a white-centred fulvous-ringed black ocellus in interspace 2, and two preapical, smaller similar ocelli, followed by a very sinuous subterminal and a straighter terminal dark brown line. Hindwing: basal two-thirds blackish brown, terminal border broadly paler, bearing normally seven ocelli similar to those on the forewing, and subterminal and terminal dark brown lines.[1]

Dry-season form: Upperside as in the wet-season form. Underside differs in the ocelli being indistinct or absent, and the subterminal and terminal dark lines on both forewing and hindwing absent or very faint; the terminal margins are broadly rufescent (reddish) brown, fading inwardly into lilacine, the oblique white bar on the forewing outwardly diffuse. Antennae, head, thorax and abdomen dark brown; the antennae ochraceous towards apex.[1]
