Honeybees sampled from 285 colonies at 57 localities were morphometrically analysed. The multivariate analysis established five statistically separable morphoclusters occupying ecologically different areas: Apis mellifera jemenitica in the northwest and eastern arid and semi-arid lowlands; A. m. scutellata in the west, south and southwest humid midlands; A. m. bandasii, in the central moist highlands; A. m. monticola from the northern mountainous highlands; and A.m.woyi-gambell in south western semi-arid to sub-humid lowland parts of the country. Moreover some areas with high inter and intracolonial variances were noted, suggesting introgression among these defined honeybee populations.

Key words: Apis mellifera / morphometry / race / introgression / Ethiopia
