AbstractThe larval descriptions of 'Uranotaenia (Pseudoficalbia) sp. indet.' by Ramos & Ribeiro (1975) and 'the atypical larvae of Ur. (Pfc.) fusca Theobald,1907' by Mattingly (1954) actually refer to Uranotaenia (P.) nigripes (Theobald, 1905). Characters to the separation of 4th-stage larvae of nigripes and fusca are given. The known distribution of nigripes, confined to the West African (Guinean-Congolese) subregion, is shown on a map. The species is recorded for the first time from Kenya and Angola. The ratio saddle height/saddle length in the 4th-stage larva of fusca decreases clinally in the direction southwest to northeast in the southern part of its range.
