Wings: membrane hyaline, longitudinal and cross veins yellowish-brown, costal brace dark brown; cross veins between longitudinal veins C and RP 1 clouded with brown, clouds more extensive on cross veins between Sc and RP 1; 4–5 cross veins basal to bulla, 15–16 distal to bulla. Abdomen: dark brown with light brown lines U shaped, terga IX similar to male; egg guide dark brown, apically acute (Fig. 3J–K). Caudal filaments white with black annulations on basal fourth and apex of each annulation.
Female subimago (Fig. 2C) General coloration brown, similar to female imago. Wings opaque, covered by microtrichia; longitudinal veins yellowish opaque tinged with brown, cross veins dark brown; cross veins between C and RP 1 clouded. Egg guide brown, whitish brown toward apex.

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.
