Notes on Ethiopian Anophelini

Extract

Edwards (Bull. Ent. Res., 1930, 21, p. 290) originally described this species from the Belgian Congo. Two further adults from Ndola, N. Rhodesia, were examined by Evans (Mosquitoes of the Ethiopian Region, II, Anophelini, 1938, p. 246) who noted that these differed from the type species in having the costa without a pale sector spot and the third vein with a large dark area at the apex. The present specimens (also from Ndola) show that these differences are not constant; in one of the two females there is a small sector spot present on one wing, the other wing and both wings in the second female have no sector spot, both females have a rather small dark area at the apex of the third vein. In two of the three males a sector spot is present on both wings, while in the third specimen this spot is absent from both wings. On the whole the wings may be said to be darker than those of typical walravensi from the Congo, and these Ndola specimens may be taken as representing a darker form but not worth subspecific rank. Associated with these five adults were four larval pelts and five pupal pelts obtained from isolated specimens. We therefore take this opportunity of describing the larva and pupa.
