Subspecies and variation

There is a slight variation in size and in the width and intensity of the color of the pale areas; two subspecies are recognized.

Similar species

G. meyeri is rather similar to G. eurypylus pamphylus with which it occurs in the same area , but in the latter the white band on the underside of the hindwing is continuous from costa near the end of vein 7 towards tornus.
