Common Silverline
 The space between the central band and the outer band is quite wide on the under side of the hind wing of both sexes. Also, the underside has a pale yellow ground colour with orange bands that are edged with black. The orange area on the upper side is more restricted than the Plumbeous Silverline, which it resembles very closely.

Male: The upper side of the hind wing does not usually have any trace of shot-blue. If it does, it is a darker shade of blue than the Plumbeous Silverline.

Female: No blue on upper sides.

Plumbeous Silverline
Both sexes are slightly larger than the Common Silverline. The orange areas on the upper sides are more extensive and scattered than in any other Silverline. The underside has a pale yellow ground colour with yellowish brown bands that are edged with black.

Male: The brilliant shot-blue on the upper sides of the hind wing is lighter than in any other species. There is no blue on the forewing.

Female: The upper sides of the forewing are profusely dusted with plumbeous scales, hence its name.

Clouded Silverline
The first band  on the hind wing (the band closest to the base of the wing) is broken into three small spots. The underside of both sexes is an unmistakable brick red.

Ceylon Silverline
In both sexes, the first band on the under side of the hind wing is divided into 3 small spots. The under sides are pale yellow with well defined markings in the wet season form and khaki with more diffused markings in the dry season form. The bands on the undersides are pale orange brown.

Male: The shot-blue on the upper side of the hind wings always extends to the lower margin of the forewing in varying degrees; in the wet season forms it stops at vein 1 while in the dry season forms it may extend all the way to vein 3. The blue is intermediate in shade between the darker blue of the Long Banded Silverline and the lighter coloured Plumbeous Silverline.

Female: No shot-blue on the upper sides.

Scarce Shot Silverline
Male: Extensive shot-blue on both wings above.

Females: No blue on the upper sides. In both sexes, the undersides are khaki to reddish brown but not as dark as in the Couded Silverline. The first band on the hind wing is broken into three spots, as in the Ceylon Silverline. The bands on the under sides are reddish orange. This is a rare butterfly of the dry zone.

Long-banded Silverline
The largest Silverline in the group. The bands on the undersides are dark red to crimson, and the ground colour is a bright pale yellow. The second band on the under side of the hind wing joins the central band towards the distal end; a feature that distinguishes it from all other Spindasis.

Male: Brilliant shot-blue on the upper side of both wings.

Female: Devoid of any blue or orange markings on the upper side.
