039987A1FF8FD03FFF0157D8C6985767.taxon	description	Description. General color brown. Head light brown with central part yellowish; clypeal area setose; M-line incomplete, slightly visible and with diffuse limits; (Fig. 2); lappets brown; gena and parietalia light brown; postfrontal line U-shaped; antenna and palps brow.

Forewing length 11.1 – 11.7 mm. Hammer a truncate cone (Fig. 3). Penial armature with a pair of small ventral, membranous lobes (Figs. 4 – 6); in dorsal view, 3 - lobed apically with lateral lobes (shoulders) well sclerotized (Fig. 4); ventral apical part (Fig. 5) a thin flap-shaped sclerotized structure (ventral membranous lobes are attached to this structure); hooks relatively large, regularly curved and with apex pointed (Fig. 5); dorsal keel absent. Female. Forewing length 14.7 – 15.5 mm. Subgenital plate light brown and 4 - lobed (Fig. 7). Median notch relatively deep, mesal lobes wider than lateral ones. Lateral lobes slightly shorter than medial ones. Egg elongate oval, ca. 0.22 x 0.45 mm (Fig. 8). Nymph. General color dark brown. Head dark brown with lighter areas near ocelli, compound eyes and parietallia (Fig. 9); M-line slightly visible and with diffuse limits; eyes and ocelli black. Pronotum dark brown with median line and scattered areas light brown (Fig. 9). Mandibles, maxillae, and labium as in Figs. 10 – 12, respectively. Forefemur with lateral surface covered by sparse bristles (Fig. 13); dorsally and ventrally with higher density of thick bristles; dorsally, with strong fringe of hairs. Tibia ventrally with sparse thick bristles, and dorsally with a row of thick bristles and a well-developed band of hairs. Cerci dark brown with thick bristles; segments differ in shape and size from base to apex (Fig. 14). Thoracic gills: ASC 1, PSC 1, AT 2, AT 3 and PT 3 (sensu Shepard & Stewart 1983; Stewart & Stark 2002). Measurements (n = 5): head width 2.9 – 3.1 mm; head length 1.7 – 1.9 mm; antennae length 5.5 – 5.8 mm; pronotum width 3.0 – 3.4 mm; pronotum length 1.8 – 2.5 mm; cercal length 6.9 – 7.1 mm; total length (without cerci) 10.9 – 11.5 mm.	en	Novaes, Marcos Carneiro, Vilela, Diogo Silva, Lopez, Vinicius Marques, Ferreira, Rhainer Guillermo Nascimento (2018): Certain species of Plecoptera from the headwater springs of National Integration River (São Francisco), Brazil.

039987A1FF8FD03FFF0157D8C6985767.taxon	discussion	Remarks. The penial armature of A. saofrancisco resembles A. tabatae Froehlich 2010 a. However, the apical penial structure of A. saofrancisco is wider than A. tabatae, as shown in ventral, dorsal, and lateral views (Figs. 4 – 6). Additionally, A. tabatae has only a single ventral membranous lobe, whereas A. saofrancisco has two. The head and pronotal color pattern of the nymphs of A. saofrancisco resembles that of A. flintorum Froehlich 2002 (Almeida et al., 2018). However, the nymph of A. saofrancisco is lighter than A. flintorum. Furthermore, the M-line in A. flintorum is well defined but indistinct in A. saofrancisco.	en	Novaes, Marcos Carneiro, Vilela, Diogo Silva, Lopez, Vinicius Marques, Ferreira, Rhainer Guillermo Nascimento (2018): Certain species of Plecoptera from the headwater springs of National Integration River (São Francisco), Brazil.

039987A1FF8CD03FFF015511C1B3543F.taxon	discussion	Remarks. It is not presently possible to identify specifically the nymph of this taxon collected from this spring. The general habitus including the coloration appears to be different from other nymphs studied from this area. Associated male adults will be necessary for positive identification.	en	Novaes, Marcos Carneiro, Vilela, Diogo Silva, Lopez, Vinicius Marques, Ferreira, Rhainer Guillermo Nascimento (2018): Certain species of Plecoptera from the headwater springs of National Integration River (São Francisco), Brazil.
