The male of G. brasiliensis Šámal, 1921 and the female of G. flinti Froehlich, 1993 are described. New figures for G. maculosa Jewett, 1960, for the male of G. reticulata Brauer, 1866, and for the female of G. brasiliensis are provided. Keys to adult males and to nymphs are provided.

Introduction
The Family Gripopterygidae, Gripopteryx, new species, Brazil Introduction The family Gripopterygidae is the most diverse among Antarctoperlaria, with 55 genera and about 300 described species (DeWalt et al. 2010), distributed in South America, Australia and New Zealand (Zwick 2000). For South America, 83 species in 26 genera are recorded (Froehlich 2010). Brazil has only four genera, all belonging to the subfamily Gripopteryginae McLellan, 1977: Gripopteryx (Pictet, 1841), Paragripopteryx Enderlein, 1909, Tupiperla Froehlich, 1969 and Guaranyperla Froehlich, 2001.
Gripopteryx was originally proposed by Pictet (1841) as a subgenus of Capnia; Klapálek (1904) elevated Gripopteryx to generic level. Enderlein (1909) proposed the family Gripopterygidae, with Gripopteryx as type genus. Until Jewett (1960) and Illies (1963) the genus had not been well defined and, in fact, encompassed several genera. The present delimitation of the genus was made by Froehlich (1969, 1990).
Gripopteryx has 17 described species, including the two new species described here: G. cancellata (Pictet, 1841), G. reticulata Brauer, 1866, G. brasiliensis (Šámal, 1921), G. serrei Navás, 1930, G. pardina Navás, 1936, G. garbei Navás, 1936, G. maculosa Jewett, 1960, G. elisae Illies, 1964, G. juetah Froehlich, 1990, G. pilosa Froehlich, 1990, G. coruja Froehlich, 1993, G. pinima Froehlich, 1993, G. liana Froehlich, 1993, G. serrensis Froehlich, 1993, G. flinti Froehlich, 1993, G. japi n. sp., G. clemira n. sp. The genus occurs from northeastern Argentina, Paraguay and Uruguay to Brazil, including the mountains of southern, southeastern and central Brazil, and along the southern Brazilian coast (Froehlich 1993) up to the south of the Northeastern Region (Fig. 1). Their nymphs are found on rocks, leaf packs or moss in running water, and often more than one species is found in the same stream. Adult coloration is dark brown or gray, and they are somewhat active during the day, but can be collected at light traps.
In this study we present a revision of the genus Grypopteryx in South America and describe two new species. In addition, we describe the male of G. brasiliensis, the female of G. flinti, and present new comparative figures of G. reticulata, G. brasiliensis and G. maculosa. Keys to adult males and nymphs are also provided.
