Resumo: | The stingless bee species Melipona quadrifasciata includes two subspecies, Melipona quadrifasciata anthidioids and Melipona quadrifasciata quadrifasciata. The morphological difference between the two subspecies is the presence of three to five continuous yellow stripes on the terga on the 3rd to 6th segments in workers and males of M. q. quadrifasciata, and two to five interrupted bands in M. q. anthidioides. We identified a DNA marker which is present in M. q. quadrifasciata and absent in M. q. anthidioides. Only one among the M. q. quadrifasciata colonies did not present the marker. It was also absent in bees collected in northern Minas Gerais State (Brazil), despite their morphological resemblance to M. q. quadrifasciata. The marker can be used for studying the genetic structure of the hybridization zone formed by the intercrossing of the two subspecies.
