[3] Hyperolius swynnertoni was described by Vivian Frederick Maynard FitzSimons in 1941, based on material collected from Chirinda Forest near Mount Selinda, Zimbabwe.

[2] Hyperolius marmoratus broadleyi, which may or may not be synonymous with this species,[3] has a light mid-dorsal band running the whole length of the animal, and a pair of dorso-lateral light bands running from edge of upper eyelid and upper half of eye to base of leg.

[2] Hyperolius swynnertoni is associated with emergent vegetation at the margins of swamps, rivers and lakes in savannas, grasslands and forest edges, as well as many human-modified habitats such as cultivated land and gardens.

Breeding takes in a variety of aquatic habitats, both temporary and permanent, ranging from very small to very large ponds.

[1] Hyperolius swynnertoni is an extremely abundant and adaptable species that spreads rapidly into recently created waterbodies; there are no significant threats.
