The call of Hyperolius wermuthi is similar to that of H. f. fusciventris from the same areas, but apparently slower and higher pitched.

§Habitats[edit]
Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, swamps, and intermittent freshwater marshes. It is threatened by habitat loss and environmental damage.

A small forest Hyperolius (males 18–23 mm, females 22–29 mm) from western West Africa, similar to H. fusciventris but phase J never with a dark vertebral line. In life Phase F with red canthal stripe. No dark lateral pigmentation. Ventrum transparent bluish green. Pupil horizontal.
This frog is remarkably similar to H. fusciventris, especially after preservation, but differs in a number of minor morphological characters and, in life, by its ventral coloration. Furthermore H. fusciventris is a bushland form while H. wermuthi is a forest form, so although their ranges overlap they may not actually be sympatric.The correct name for this species may be Hyperolius soror Chabanaud 1921, type locality N’Zerekoré, Guinea.
This species shows developmental changes in patterning, with two phases, J (juveniles and many mature males) and F (mature females and some mature males). All newly metamorphosed individuals are phase J, which is normally brownish to green with paired light dorsolateral lines, or an hourglass pattern. All females, and some males, develop into phase F before the first breeding season. Phase F is often colorful and variable, showing the diagnostic color characteristics for the species or subspecies. Either well-defined morphs may be present, or graded variation.

This species is known only from southern Guinea, Liberia and western Cte dIvoire. It is so similar to Hyperolius fusciventris that it might well be overlooked. It probably occurs up to over 1,000m asl on Mount Nimba.

Found in swamps in dense forest. Only known from a small forested area in Liberia and Côte dIvoire, but may have been overlooked elsewhere in West Africa since it is so similar to H. fusciventris.
