Material: Holotype and 1 paratype male imagos from Brazil, Minas Gerais, rio Peixe / rio Itambé confluence, S 19º 17.525' - W 43º 15.457', 500 m, 4-II-1998, Holzenthal & Paprocki Cols . Holotype deposited at MZSP, paratype at IFML .

Etymology: We dedicate this species to H. Paprocki, Trichoptera specialist, one of the collectors of the type material.

Discussion: The male imago of Askola paprockii sp. nov. can be distinguished by the following combination of characters: 1) General coloration yellowish white with grayish marks ( Figs. 4–5 ), wings with grayish spots ( Fig. 26 ); 2) dorsal portion of eyes grayish black, eyes widely meeting dorsally on meson of head ( Fig. 6 ); 3) 4 costal cross veins from bulla to costal brace ( Fig. 26 ); 4) forceps whitish except basal half washed with gray ( Fig. 5 ); 5) penes not extending beyond posterior margin of styliger plate ( Figs. 31–32 ).
