RESUMO

The term "spermiocladistics" express the use of structural and ultrastructural charcteristics to compose character matrices for phylogenetic studies. Such studies, carried out for different animais, including insects, have been shown to be consistent and useful, at least for higher taxa. Therefore, we proposed, in this thesis, to carry out a detailed ultrastructural analysis of the spermatozoa of the tribes: Melliponini, Euglossini and Bombini, in order to identify characters that could potentially contribute to the understanding of phylogenetic relationships in this group. For this study, we employed the methods: (1) light microcopy using phase contrast, DAPI fluorescence and (2) transmission electron microscopy with conventional preparations and cytochemistry (EPT A). Our data were compared with those described in the literature for the Apini tribe, so as to compose a consistent character matrix. Phylogenetic analysis of our data suggested (Meliponini (Euglossini (Bombini + Apini»). However, we believe that our data should be considered together with the data obtained with research on somatic morphology, behavior and molecular biology, in an effort to develop more consistent results. This thesis includes two manuscripts that are being submitted for publication, one was accepted and one article already published: : Zama, U., Uno-Neto, J. &Dolder, H. 2001. Ultrastructure of spermatozoa in P/ebeia (P/ebeia) droryana Friese (Hymenoptera: Apidae: Meliponina). Journal of Hymenoptera Research, 10 (2): 261-270
