Populations of Anopheles annulipes Walker s. 1. from eastern and northern Australia were studied by crossing to a laboratory colony (Standard) and, in some cases, to each other. The resulting adult females had normal reproductive systems. Some of the crosses produced males with reduced testes. Extensive asynapsis, with or without banding sequence differences in the polytene chromosomes, characterised many of the progeny of the crosses. Four new X chromosomes were revealed and are illustrated. Rearing parameters showed evidence of genetic incompatibility between the chromosomal types. Duration of copulation was also found to vary. The evidence presented in this paper suggests that the taxon is a complex of up to 10 species.
