Stenoscelidea albovaria Westwood, 1842

= Stenoscelidea histrionica ( Stål, 1859) , syn. nov.

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 .
