    ABSTRACT

    The pupa of Stilobezzia (Eukraiohelea) elegantula is described and illustrated, being the first description of a pupa for a species belonging to this subgenus. The studied material was collected large banks of floating aquatic macrophytes in the Marchantaria Island, in the municipality of Iranduba, Amazonas, Brazil, located at 15 km from Manaus, and surrounded by the white waters of the Solimões river. The collected pupae were isolated and observed in the laboratory until the adult emergence and then identified as S. (E.) elegantula. The described pupa is compared with those of Neotropical species Stilobezzia (Stilobezzia) punctulata and S. (S.) rabelloi.
