The immature stages of Euschistus hansi Grazia, 1987 are described and illustrated, with emphasis on the external morphological characters of the egg and five instars. Adults and nymphs were fed on fresh branches and ripe fruits of "ligustro", Ligustrum lucidum Ait. (Oleaceae). Nymphs of E. hansi are compared to previously described immatures of other Neotropical species of Euschistus Dallas, 1851: E. heros (Fabricius, 1798), E. sulcacitus Rolston, 1971 and E. bifibulus (Palisot de Beauvois, 1805). Biological data are also provided.
