Resumo

Summary—The behaviour and morphology of dwarf gynes produced in worker-sized cells of nor- mal colonies in Nannotrigona testaceicornis (Meliponinae, Trigonini) were studied.The behaviour of these dwarf virgin queens was the same as observed for normal Trigonine gynes.The glandular equipment is also the same: Dufour glands, fat bodies and spermathecae are present.Despite these similarities, their ovaries are different.The functional significance of dwarf gynes is unknown, but may be a basis for an alternative reproductive strategy.dwarf gynes / larval food /
