Comment

In the Hyperolius concolor superspecies according to Schiøtz, 1975, Treefrogs E. Afr.: 113. Easily confused with Hyperolius quinquevittatus, to which Schiøtz's Malawi record should be referred. See comment under Hyperolius raveni and Hyperolius pustulifer. Poynton and Broadley, 1987, Ann. Natal Mus., 28: 196-197, considered material from Malawi, allocated by previous authors to Hyperolius kivuensis to Hyperolius quiquevittatus.
