Abstract
Morphometric multivariate analyses were carried out in order to separate the females of the closely related anthropophilic and non-anthropophilic members of the Simulium damnosum s.l. complex occurring in western Uganda. Simulium kilibanum (= ‘Nyamagasani’), ‘Nkusi’, ‘Sebwe’ and S. pandanophilum were compared with the West African S. damnosum subcomplex, S. soubrense and S. yahense to correlate the results with those of previous studies. Simulium pandanophilum could be clearly discriminated. However, only 72%–88% of identifications among the closely related S. kilibanum, ‘Sebwe’ and ‘Nkusi’, which all belong to the ‘Sanje’ subcomplex, were correct. The two forest species S. soubrense and S. yahense slightly overlapped but were distinct from all others.
