Introduction
Plecoptera nymphs are generally found in water courses, especially in the rithral zone.
Together with Ephemeroptera and Trichoptera, they are important water-quality indicators.
The order is composed of sixteen families and approximately 2000 species (Zwick,
1974; Romero, 2001). The majority of these families are concentrated in the temperate
regions of both hemispheres (Illies, 1965). The distribution of the global fauna was cataloged by Classen (1940), Illies (1966) and Zwick (1973); in North America, Stark et al.
(1986) and Stark (2001b) recorded 628 species in nine families. About 100 species of Plecoptera are known from Brazil, belonging to two families: Perlidae and Gripopterygidae
(Froehlich, 1969, 1984a, b, 2002, 2003; Ribeiro-Ferreira & Froehlich, 1999, 2001).
Species of Perlidae found in South America belong to the tribe Anacroneuriini of the
subfamily Acroneuriinae, and are placed in ten genera. In Brazil the following genera are

present: Anacroneuria Klapálek; Macrogynoplax Enderlein; Enderleina Jewett and Kempnyia Klapálek.
The genus Anacroneuria is distributed over all South and Central America; two species reach the Nearctic region: Anacroneuria comanche Starck & Baumann, in Texas
(Stark & Baumann, 1987) and Anacroneuria wipukupa Baumann & Oslo, in Arizona
(Baumann & Oslo, 1984), which are present in mountainous regions as well in lowland
regions. Stark (2001a) estimated that the number of species in South America is over 300,
while in Brazil, 31 species have been recorded (Froehlich, 2002, 2003; Ribeiro-Ferreira &
Froehlich, 2001). The Anacroneuria species occurring in Brazil are: A. minuta Klapálek;
A. manauensis Ribeiro-Ferreira; A. marlieri Froehlich; A. badilinea Jewett; A. debilis Pictet; A. dilaticollis Burmeister; A. fuscicosta Enderlein; A. impensa Jewett; A. novateutonia
Jewett; A. oculatila Jewett; A. plaumanni Jewett; A. polita Burmeister; A. subcostalis
Klapálek; A. tinctilamella Jewett; A. trimacula Jewett; A. cathia Froehlich; A. coscaroni
Froehlich; A. flintorum Froehlich; A. stanjewetti Froehlich; A. petersi Froehlich; A. rondoniae Froehlich; A. saltensis Froehlich; A. caraja Froehlich; A. toriba Froehlich; A.
uyara Froehlich; A. xinguensis Froehlich; A. ytuguazu Froehlich; A. blanca Stark; A.
pastaza Stark; A. fittkaui Froehlich and A. amazonica Froehlich.
Macrogynoplax nymphs occur in habitats similar to those of Anacroneuria, but in
Central Amazonia the first genus present lower frequency and abundance than the latter
(Bobot & Hamada, 2002). This genus is comprised of thirteen species, six of which are
present in Brazil: M. guayanensis Enderlein; M. veneranda Froehlich; M. delicata Ribeiro
& Froehlich; M. pulchra Ribeiro & Froehlich; M. poranga Ribeiro & Froehlich and M.
marauia Froehlich (Ribeiro-Ferreira & Froehlich, 1999; Froehlich, 1984 b, 2003). The
other species are recorded in other northern South American countries such as Peru, Venezuela, Suriname and Guiana (Stark, 2001 a).
The genus Enderleina, with five described species, is restricted to northern South
America (Brazil and Venezuela). These species are: E. preclara Jewett; (Roraima, Brazil
and Venezuela); E. yano Stark (Cerro de la Neblina, Venezuela); E. flinti Stark (Cerro de la
Neblina, Venezuela); E. bonita Stark (Venezuela) and E. froehlichi Ribeiro-Ferreira (Amazonas, Brazil) (Ribeiro-Ferreira, 1995; Stark, 1989, 2001 a).
The genus Kempnyia, with 30 species, can be found in mountainous regions of southern and eastern Brazil (Stark, 2001 a). The following species occur in Brazil: K. alterosarum Froehlich; K. auberti Froehlich; K. barbiellinii (Navás); K. brasilica (Navás); K.
brasiliensis (Pictet); K. calabriae Jcost; K. colossica (Navás); K. flava Klapálek; K. gracilienta (Enderlein); K. guassu Froehlich; K. jatim Froehlich; K. klugii (Pictet); K. mirim
Froehlich; K. neotropica (Jacobson & Bianchi); K. obtusa Klapálek; K. petersorum Froehlich; K. petropolitana (Navás); K. reichardti Froehlich; K. remota (Banks); K. reticulata
(Klapálek); K. sazimai Froehlich; K. serrana (Navás); K. sordina Klapálek; K. tamoya
Froehlich; K. taunayi (Navás), K. tenebrosa Klapálek; K. tijucana Dorvillé; K. umbrina

hlich, 1984 a, 1988, 1996; Jcost, 1980; Stark, 2001 a).
Gripopterygidae are primarily oligostenothermic, and they are distributed in mountainous regions, spreading from south to west along the Andes as far as Peru and probably
to Colombia (Claudioperla Illies) and to the east as far as the mountains of south, southeast and central Brazil (Froehlich, 1981, Romero, 2001). Four genera of this family are
present in Brazil: Tupiperla Froehlich, 1969; Paragripopteryx Enderlein, 1909; Gripopteryx Pictet, 1841 and Guaranyperla Froehlich, 2001.
The genus Tupiperla is represented by sixteen species in Brazil, Paraguay and Argentina. Ten species occur in Brazil: T. gracilis Burmeister; T. tesselata Brauer; T. eleonorae
Froehlich; T. illiesi Illies; T. modesta Froehlich; T. oliveirai Froehlich; T reichardti Froehlich; T. robusta Froehlich; T. sulina Froehlich and T. umbya Froehlich (Froehlich, 1998).
The genus Paragripopteryx has been reported in Uruguay, Argentina, Paraguay and
Brazil. Nine of the ten described species occur in Brazil: P. klapaleki Enderlein; P. anga
Froehlich; P. blanda Froehlich; P. delicata Froehlich; P. guardae Froehlich; P. merui Froehlich; P. hamata Froehlich; P. eleonorae Froehlich and P. egena Froehlich (Froehlich,
1994 ).
The genus Gripopteryx is represented by twelve species, all of which occur in Brazil:
G. cancellata Pictet; G. reticulata Brauer; G. garbei Navás; G. juetah Froehlich; G. pilosa
Froehlich; G. pardina Navás; G. maculosa Jewett; G. coruja Froehlich; G. pinima Froehlich; G. liana Froehlich; G. serrensis Froehlich and G. flinti Froehlich (Froehlich 1990;
1993).
The genus Guaranyperla is represented by three species: G. guapuiara Froehlich; G.
beckeri Froehlich and G. nitens Froehlich; all of them can be found in the southeastern
region of Brazil (Froehlich, 2001). This genus can be easily distinguished from the others
based on autapomorphism (especially at the nymph stage) such as lateral extension of the
pronotum flanking the head (Fig. 35), vesicular setae covering the body (Fig. 35) and posterior extension of urotergite X (Figs 35, 36).
The first stages of all species are, in general, very similar, making it difficult to distinguish between them. Adults and last-instar nymphs have similar aspects and dimensions;
however, instead of wings last-instar nymphs have wing pads on the meso and metathorax
and, in most cases different species have different color patterns. Many nymphs breathe
with thoracic gills, which are exposed in branches along the body; their number, position
and aspect have great taxonomic importance (Shepard & Steward, 1983).
One of the major problems in the study of Brazilian Plecoptera is the lack of general
literature bringing together information about all of the groups that occur, especially for
identification of the immature forms. Froehlich (1984 c) and Dorvillé & Froehlich (1999)
provided keys to perlid nymphs from southeastern Brazil; Hamada & Couceiro (2003)
published a key to perlid nymphs from Central Amazonia and Froehlich (2003) provided a
key for identification of known female and male Macrogynoplax species. Unfortunately,
there are no keys to the genera/species of Gripopterygidae.

In view of the lack of compiled information on Plecoptera from Brazil, the objective
of this study is to provide an illustrated key for identification of nymph genera recorded
for Brazil.
Material and Methods
The specimens used for establishing the identification key belong to the Entomological
collection of the Departamento de Zoologia, Instituto de Biologia, Universidade Federal
do Rio de Janeiro (UFRJ) and Instituto Nacional de Pesquisas da Amazônia (INPA).
The characters used in the identification key provided are based on the works of Dorvillé and Froehlich (1999), Froehlich (1969, 1984 c, 1990, 1993), Hamada and Couceiro
(2003), Stark (1989) and on new characters observed. All line drawings were prepared
with a drawing tube mounted on a Zeiss SV6 stereomicroscope. We observed, whenever
possible, a minimum of ten specimens of distinct species of each genus.
The present key is adequate for last-instar nymphs, since at the earlier nymphal stages
identification is difficult. One example of this situation can be observed on the Paragripopteryx and Gripopoteryx nymphs that are very similar at the beginning of their development. The nymphs of Kempnyia and Enderleina, although very similar, have different
geographical distributions without overlap, which can be used to distinguish them; Kempnyia is restricted to southern and southeastern Brazil. Also, the two genera can easily be
distinguished by the extension of the ventral sulcus in the femur; however this character
needs to be used with caution since only a small number of Enderleina specimens have
been examined.
