Abstract: Internal transcribed spacer 1 (ITS-1) sequences of the nuclear rDNA of eight bee species of the genus Melipona were studied. Complete ITS-1 sequence and flanking regions from three Melipona species were PCR-amplified, cloned, sequenced, and their variability compared. These sequences show length variation (1391 to 1417 bp), several repeated elements of one, two, three, and four nucleotides, and a repeated tandem sequence of approximately 80 bp. The low variation level between M. quadrifasciata and M. mandacaia sequences supports the hypothesis that they diverged recently. PCR-amplification, cloning, and sequencing of a partial ITS-1 sequence (394 to 496 bp) of eight Melipona species and two outgroups were performed and the obtained sequences used for phylogenetic analysis. The single tree estimated from parsimony analysis recovered four well-defined clades and monophyly of the genus Melipona. The phylogenetic relationships derived from sequences of ITS-1 fragments corroborate the taxonomic classification of Melipona based on morphological characters.
