Last instar nymph description. General color brown. Head brown with M-line ochraceous to yellowish ( Fig. 2View FIGURES 2–7); anteriorly parietalia brown and posteriorly ochraceous to yellowish; eyes and ocelli black; clypeal area yellowish; labrum brown; postfrontal line as an open V ( Fig. 2View FIGURES 2–7); mouthparts as in Figs. 3–5View FIGURES 2–7, mandibles with a dense brush of bristles in molar area ( Fig. 3View FIGURES 2–7); palpi pale yellow; scape, pedicel and flagellum ochraceous. Pronotum brown with thin median line and rugosities light yellow ( Fig. 2View FIGURES 2–7). Forefemur brownish dorsally and ochraceous ventrally; dorsal surface covered by setae and with a glabrous longitudinal line; dorsal surface also covered by sparse bristles, which are more robust and reach higher density in the posterodorsal part; posterior part of the femur with a band of bristles ( Fig. 6View FIGURES 2–7). Tibia anteriorly with sparse thick bristles, and posteriorly with a row of thick bristles and a well-developed band of hairs ( Fig. 6View FIGURES 2–7). Tarsus brownish. Abdomen brown dorsally and ochraceous to yellow ventrally. Cerci light brown with thick bristles; segments differ in shape and size from base to apex ( Fig. 7View FIGURES 2–7). Thoracic gills: ASC1, PSC1, AT2, AT3 and PT3 (sensu Shepard & Stewart, 1983; Stewart & Stark, 2002).

Remarks. Compared to the other known Brazilian Anacroneuria  nymphs that are known, A. iporanga  has the head and pronotum pattern similar only to A. flintorum ( Almeida et al., 2018)  . However, the two species differ in the light spots near the ocelli and M-line. In addition, the nymph of A. iporanga  has the dorsal surface of the forefemur with a higher density of thick bristles than that of A. flintorum  .

Biological notes. Nymphs of A. iporanga  occurs mainly in riffles of small streams with fast currents. The preference for riffles may suggest that this species requires well-oxygenated lotic habitats, similar to other species of Anacroneuria  . Examination of stomach contents of Anacroneuria  nymphs have indicated that they are predatory consuming mainly Ephemeroptera, Trichoptera  , and Diptera  immature, as shown for Kempnyia  ( Dorvillé & Froehlich, 2001; Bispo & Froehlich, 2008). In A. iporanga  , we identified two preferred prey items Simuliidae  ( Diptera  ) (63.5%) and Ephemeroptera  (26%). The mayflies were represented by two families, the Baetidae  and Leptophlebiidae  . The predominance of the Simuliidae  in the diet was expected since larvae occur abundantly in riffles with A. iporanga  .
