Abstract
Morphometric studies were carried out on Glossina pallidipes from Zimbabwe in southern Africa and Uganda in eastern Africa. Ten and seven characters were used in the multivariate discriminant analysis for the male and female populations respectively. All the characters showed highly significant morphological discrimination «0.001) between the two populations. These were further confirmed by the separate scatterplot for each sex population. The consistent discriminant characters between the male and female population are: 2nd and 3rd antennal segment length, head narrowest point width arid eye base to bucca tip length. The most powerful discriminator between the male populations is the 2nd and 3rd antennal segments length whereas in the female populations it is the eye base to bucca tip length. The percentage of “grouped” cases correctly classified for each sex populations was 100 with no overlap. The morphological variations observed between the allopatric populations in relation to biological species concepts are discussed.
