About Hyperolius semidiscus Hewitt, 1927
Hyperolius semidiscus Hewitt, 1927 can reach a snout–vent length of 35 mm (1.4 in). Its dorsum is either green or brown. Individuals of this species typically have sharp-edged yellow canthal–dorsolateral lines, which often have a thin black outline. The hidden surfaces of the limbs, digits, and interdigital webbing are yellow or orange. The venter is cream or yellow, and males have a dark yellow gular flap. The pupil of this species is horizontal. Tadpoles of Hyperolius semidiscus grow up to 48 mm (1.9 in) in total length. The male advertisement call consists of a harsh "creak", with occasional longer, pulsatile "croaks". This species inhabits savanna and thicket habitats, mostly at low elevations, but it can occasionally be found as high as 1,000 m (3,300 ft). It is most often found in dense reeds and emergent vegetation growing along rivers and pans. Breeding occurs in semi-permanent water bodies. Hyperolius semidiscus is an uncommon species. Local populations are negatively impacted by afforestation, agricultural activity, and urban expansion. However, the species may benefit from the spread of invasive water hyacinth, which provides suitable breeding habitat. It occurs in several protected areas.
