The present paper briefly describes the Lithosiini genitalia and discusses their terminology. Twelve new terms are introduced: medius, introrsum, conjuga, collis, iuba, jugum basalis, jugum distalis, arcus, intersaccular bridge, lamella centralis, clasper region, and elasma for the male genitalia, and diverticulum bursae for the female genitalia. The terminological inconsistencies in Noctuidae are discussed with reference to the original concept by the various authors who introduced the terms, and the approaches by authors sensu auct. are also considered. In cases of discrepancies the terms preferable are suggested. Fully annotated figures are provided for the structures discussed.
