 Last instar nymph description. General color brown. Head brown with M-line ochraceous to yellowish (Fig. 2); anteriorly parietalia brown and posteriorly ochraceous to yellowish; eyes and ocelli black; clypeal area yellowish; labrum brown; postfrontal line as an open V (Fig. 2); mouthparts as in Figs. 3–5, mandibles with a dense brush of bristles in molar area (Fig. 3); palpi pale yellow; scape, pedicel and flagellum ochraceous. Pronotum brown with thin median line and rugosities light yellow (Fig. 2). 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. 6). Tibia anteriorly with sparse thick bristles, and posteriorly with a row of thick bristles and a well-developed band of hairs (Fig. 6). 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. 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.
