977887E4FFF4FF8BFF31F9A3FC0BFD55.taxon	etymology	Etymology. The name honors Gelson Luiz Fiorentin for his contribution to the knowledge of aquatic insects in Rio Grande do Sul State.	en	De, Valdelânia R., Froehlich, Claudio G.

977887E4FFF4FF8BFF31F9A3FC0BFD55.taxon	discussion	Remarks. The head pattern of A. fiorentini is distinctive, being most similar to that of A. oculatila Jewett (1959), known from Nova Teutonia, Santa Catarina, Brazil and from Misiones, Argentina (Froehlich 2002). However, in A. oculatila, the lighter central frons is enclosed by dark pigment and, in the male, the penis is very different, without a dorsal depression, with a V-shaped keel and a downsloping apex. The penial armature of A. fiorentini has some resemblance to that of A. minuta Klapálek (1922), a species from northern Brazil, especially in the deep depression in front of the keel, but in A. minuta it is deeper, and the apex is broader. In the female, A. minuta has paired patches of hairs in sternum nine.	en	De, Valdelânia R., Froehlich, Claudio G. (2007): Two new species of Anacroneuria (Plecoptera: Perlidae) from southern Brazil.

977887E4FFF6FF8BFF31FD7BFA32FA3B.taxon	etymology	Etymology. The name refers to the municipality in which it was collected. Noun in apposition.	en	De, Valdelânia R., Froehlich, Claudio G.

977887E4FFF6FF8BFF31FD7BFA32FA3B.taxon	discussion	Remarks. This species was collected together with A. fuscicosta (Enderlein 1909), to which it bears some resemblance. The latter, however, is darker and, medially on the frons, the brown pigment occupies the area from the postfrontal line to the M-line. They are readily separable by their penial armatures; that of A fuscicosta having a ventrally sloping apex, small ventral vesicles and apices of hooks blunt. In fact, the penis of A. caraa, with its lack of a keel, the large ventral vesicles and the upturned apex form a unique combination in the genus. The scaly area in the ventral membrane near the base of the hooks of A. caraa is also uncommon.	en	De, Valdelânia R., Froehlich, Claudio G.
