Etymology. This species name is given in apposition after “Saci-Pererê”, a remarkable character from the Brazilian folklore. The word “pererê” means leaping in the Tupi Guarani language.

Remarks. Pigments in forewings are usual in Hagenulopsis species and it may occur on cross veins, longitudinal veins, on the membrane or surrounding longitudinal and cross vein (Fig. 4). The males of H. perere sp. nov. are somewhat similar to males of H. diptera sharing with them the general color, the upper portion of compound eye meeting dorsally, and the brown bands on middle and apex of hind femur. However, the males of H. perere sp. nov. can be differentiated from the males of H. diptera by the remarkable brown clouds surrounding the cross veins located between longitudinal veins C to RP 1 and by a brown spot at the midlength on the outer surface of the middle femur. In addition, mature nymphs and females of H. perere sp. nov. can also be distinguished from all other species by the presence of clouds surrounding the cross veins between longitudinal veins C and RP 1.
