<I>Anopheles splendidus</I> Koidzumi is an important species due to its highly variable prevalence. The cytogenetic investigations were carried out on a mountain population of this species collected from Solan (H.P.) located at an altitude of 1200 m. The standard polytene chromosome map was produced and compared with the map produced for its population prevalent in the plains near Chandigarh. The standard banding pattern of X-chromosome and the autosomal arms 2R, 2L, 3R and 3L presented homologies to a considerable extent, as nearly 80% of the DNA rich bands were comparable in the two populations. However, both differ with respect to the incidence of paracentric heterozygous inversions in the autosomes, while the X-chromosome was free from any such structural alterations. The adaptive significance of the genomic changes has been discussed in the light ofecological differences in their habitats.
