Earlier Aulocera brahminoides was considered a subspecies of A. brahminus.[3]
Aulocera brahminoides is 50 to 60 mm in wingspan and its smaller than A. brahminus.[3]
The narrow-banded satyrs are large, powerfully built Himalayan butterflies which are black or very dark brown above. They are characterised by a white discal band across both wings. The hindwing band is narrow and even in width. The white discal spots in 1 to 4 along the inner edge of the forewing are in line. The wings are rounded with convex termens and have chequered fringes. A dark apical spot or ocellus is present on the forewing. The under hindwing is dark below, with beautiful white variegations not as prominent as the dark background.[3][4]
The tegumen is gradually sloped to the tip.[3]
In A. brahminus, the under-forewing apical ocellus is well-defined and prominently pupilled while in A. brahminoides it is less well defined, much smaller and darker. The upper-hindwing discal band to dorsum, which is a characteristic feature in A. brahminus is much curved in the case of A. brahminoides.[3]
