On the ecology and distribution of the species of the simulium damnosum complex in different bioclimatic zones of Liberia and Guinea.
A chromosomal identification of Simulium damnosum material collected in Liberia and Guinea revealed five species of this complex. S. yahense Vajime and Dunbar: Widely distributed in the rain forest zone (Liberia, Southern Guinea) and in the Fouta Djallon mountains. Breeding places typically in small watercourses, shaded streams and narrow rivers. S. sanctipauli Vajime and Dunbar: Restricted to the rain forest zone. Breeding confined to large rivers. S. soubrense Vajime and Dunbar: Breeding established in large and medium rivers under high forest (Liberia) and in the Guinea savanna (head waters of the Niger and its southern tributaries). S. damnosum Theobald: Distributed in the forest zone and Guinea savanna. Breeding in rivers and irrigation systems. S. sirbanum Vajime and Dunbar: Confined to the Northern Guinea savanna. Breeding in rivers and irrigation plants, occasionally in streams arising from lakes. Larvae of S. yahense and S. sanctipauli could be separated by morphological characters. The associations with other blackfly species are discussed.
