667887F1FFDCFFF2FF3DFC29435F1BD5.taxon	discussion	Remarks. Zwick (1972, 1973) redescribed the male and female of A. debilis. Froehlich (2002) commented on the variation in shape of the lobes of the female subgenital plate. This species has a wide distribution including Missiones and Entre Ríos (Argentina), Paraguay, and southern and southeastern Brazil (Froehlich, 2002). The species has a characteristic penial armature, which includes a transversal dorsal keel in dorsal view, prominent in lateral view. In lateral view, the apex of penial armature is triangle-shaped and, in some specimens, the extremity is directed dorsally.	en	Baldin, Carolina, Bispo, Pitágoras Da Conceição, Novaes, Marcos Carneiro (2013): New species and records of Anacroneuria (Plecoptera: Perlidae) from Rio de Janeiro State, Brazil.

667887F1FFDCFFF0FF3DF8E6412D1DDA.taxon	discussion	Remarks. The males of the above material have a forewing mean length of 10.75 mm (10 – 11 mm); forewing mean length of females was 12.75 mm (11.5 to 14 mm). This species is yellowish with two brownish stripes laterally on the pronotum. Wings have brownish subcostal veins. The color pattern of the head and pronotum of the specimens collected in Macaé agrees with the description of Jewett (1960). However, these specimens do not have the lighter window on the distal part of the wing, which is a common characteristic of A. subcostalis. The penial armature is identical to that described by Froehlich (2004).	en	Baldin, Carolina, Bispo, Pitágoras Da Conceição, Novaes, Marcos Carneiro (2013): New species and records of Anacroneuria (Plecoptera: Perlidae) from Rio de Janeiro State, Brazil.

667887F1FFDEFFF0FF3DFEE040951E74.taxon	discussion	Remarks. This species was described by Froehlich (2002) based on a single specimen collected in Nova Friburgo, Rio de Janeiro State. In the specimens studied above, the mean length of the forewings of the males is 11.25 mm (10 – 12 mm) and females 16 mm (15 – 17 mm). Anacroneuria flintorum has been recorded in streams of the mountainous regions of southeastern and southern Brazil (Froehlich, 2002; Bispo & Froehlich, 2004 a). This brown species exhibits much variability in color pattern (Bispo & Froehlich, 2004 a). However, the penial armature of all specimens examined is elongated and has hooks well separated from the vesicles, agreeing with the original description of A. flintorum (Froehlich, 2002).	en	Baldin, Carolina, Bispo, Pitágoras Da Conceição, Novaes, Marcos Carneiro (2013): New species and records of Anacroneuria (Plecoptera: Perlidae) from Rio de Janeiro State, Brazil.

667887F1FFDEFFF0FF3DFC0546601801.taxon	discussion	Remarks. This species was described by Froehlich (2002). The length of the male forewings collected in Macaé is 9 mm and 11 – 12 mm in the females. The head and pronotum have a characteristic color pattern. The head is medially brownish and partially laterally pale; pronotum is brown. The membrane of the wings is milky. The body is pale. This is the first record of the species for Rio de Janeiro State. The species can also be found in São Paulo and Paraná States (Froehlich, 2002; Froehlich, 2004; Bispo & Froehlich, 2004 a).	en	Baldin, Carolina, Bispo, Pitágoras Da Conceição, Novaes, Marcos Carneiro (2013): New species and records of Anacroneuria (Plecoptera: Perlidae) from Rio de Janeiro State, Brazil.

667887F1FFDEFFF0FF3DFADA42EC1BD2.taxon	discussion	Remarks. This species was recently described by Froehlich (2010 b) based on material collected in the Serra da Mantiqueira, São Paulo State. This represents the first record of the species in Rio de Janeiro State. In this specimen, the length of the male wing is 10 mm. As described by Froehlich (2010 b), this species can be easily confused with A. subcostalis; however, it is darker and its penial armature has a larger apex, which is slightly curved.	en	Baldin, Carolina, Bispo, Pitágoras Da Conceição, Novaes, Marcos Carneiro (2013): New species and records of Anacroneuria (Plecoptera: Perlidae) from Rio de Janeiro State, Brazil.

667887F1FFDEFFF6FF3DF8E8478A1CAA.taxon	discussion	Remarks. Anacroneuria itatiaiensis and A. fuscicosta (Enderlein 1909) are similar in color and wing length, but are distinguished by the differences in details of the penial armature and in size of hammer (shorter in A. itatiaiensis). In dorsal view, the apex of penial armature is pointed in A. itatiaiensis and rounded in A. fuscicosta. In lateral view, the penial armature of A. itatiaiensis has a strong subapical constriction, which is less pronounced in A. fuscicosta.	en	Baldin, Carolina, Bispo, Pitágoras Da Conceição, Novaes, Marcos Carneiro (2013): New species and records of Anacroneuria (Plecoptera: Perlidae) from Rio de Janeiro State, Brazil.
