Western West Africa from Sierra Leone into Guinea, Liberia, and westernmost Ivory Coast. Found in forest, sometimes open secondary forest, and savanna.

Life History, Abundance, Activity, and Special Behaviors
The species is arboreal, with the males calling from branches of bushes and trees 2-4 metres up in the forest. Although apparently associated with a typical forest fauna, K. cochranae will often call on more exposed sites at the edges of ponds or beside roads. In Sierra Leone, where several treefrogs are known to behave differently from elsewhere in their range, K. cochranae were heard calling from the ground on several occasions. Acoustically the voice is a typical Kassina call, but analysis, especially at low speeds, reveals a number of pulses with a rising frequency, rather than a rising frequency modulation of a single note as is sometimes reported for this genus.

Development takes place as in other members of the genus. Tadpoles reach up to 58 mm with a very high fin. Tooth formula 1/1+1,1.
