Two characteristic elements of the West African bushland fauna, Hyperolius concolor and H. picturatus, are strangely absent from the western half of Sierra Leone, although suitable habitats seems plentiful. Instead H. occidentalis is found, similar to both species. In morphology it is most similar to H. picturatus but has a different voice, a double or triple click, and a constant pattern. H. occidentalis differs from H. concolor in being smaller, with a shorter snout, smaller gular flap and a different pattern and voice. It is tempting to regard H. occidentalis as a western subspecies of H. picturatus. It is not done here since H. picturatus may be a composite of two cryptic species.
Captive-reared tadpoles did not develop normally but they seem to have the usual tooth formula of 1/1+1,2.
