Since the state of the art meeting in Xalapa,Mexico in 1998 our knowledge of this group has increased dramatically.We hereby present an overview of the recent accomplishments in thetaxonomic studies of the African representatives of these groups.The almost exclusively African Ceratitidine genera Ceratitis MacLeay,Capparimyia Bezzi, Carpophthoromyia Austen and Trirhithrum Bezzihave been taxonomically revised during the last decade. In the course ofthese studies 44 species new to science were described. Altogether therevised genera comprise 159 species or 88% of all known African speciesbelonging to Ceratitidina. Molecular (for some representatives of Ceratitisand Trirhithrum) and morphological (for all representatives of Ceratitisand Capparimyia) phylogenies were proposed. The phylogeneticrelationships in Ceratitis, were studied in relation to the subgenericclassification and evolutionary tendencies on host plant specificity.The African (and Middle Eastern) representatives of the Dacine generaBactrocera Macquart and Dacus Fabricius were taxonomically revised.Fifteen Bactrocera and 177 Dacus species were recognized of which 26are new to science. For Dacus, a preliminary phylogeny based on aselection of 30 exemplars from among the 66 recognized species groupswas performed, and discussed in relation to formally established subgenera,and to host specificity.56
