Comment. The examination of the type (female) of Stenoscelidea albovaria , deposited in the Hope Entomological Collections, Oxford University Museum of Natural History, Great Britain (OXUM), and the type (female) of Stenoscelidea histrionica , deposited in the Museum für Naturkunde, Humboldt Universität zu Berlin , Germany (ZMHU), allowed us to confirm that both the species are in fact conspecific. Each species was described from Brazil . Considering the precedence between the two names, S. histrionica is herein assigned as a junior synonym of S. albovaria .
