Abstract
Bemisia tabaci whitefly species are some of the world’s most devastating agricultural pests and
plant-virus disease vectors. Elucidation of the phylogenetic relationships in the group is the basis
for understanding their evolution, biogeography, gene-functions and development of novel control
technologies. We report here the discovery of five new Sub-Saharan Africa (SSA) B. tabaci putative
species, using the partial mitochondrial cytochrome oxidase 1 gene: SSA9, SSA10, SSA11, SSA12 and
SSA13. Two of them, SSA10 and SSA11 clustered with the New World species and shared 84.8‒86.5%
sequence identities. SSA10 and SSA11 provide new evidence for a close evolutionary link between the
Old and New World species. Re-analysis of the evolutionary history of B. tabaci species group indicates
that the new African species (SSA10 and SSA11) diverged from the New World clade c. 25 million years
ago. The new putative species enable us to: (i) re-evaluate current models of B. tabaci evolution, (ii)
recognise increased diversity within this cryptic species group and (iii) re-estimate divergence dates in
evolutionary time.
