Anacroneuria manauensis Ribeiro  –Ferreira, in Ribeiro– Ferreira & Froehlich, 2001: 189, Figs. 5–10View FIGURES 1 – 5View FIGURES 6 – 10; Froehlich, 2003: 130.

Diagnosis. This species is characterized by a dark head, body, and wings with a prominent, pale pronotal stripe. The ocelli are separated by twice their width and the aedeagus is sclerotized with a truncate apex. Females are characterized by the eight sternum having a deep median notch, with paramedian lobes being longer and thinner than lateral lobes.

Redescription of male. Holotype. Brown to dark brown. Body length 7.4 mm, excluding antennae and cerci ( Fig. 6View FIGURES 6 – 10). Head ( Fig. 8View FIGURES 6 – 10) medially dark brown, anteriorly light yellow with conspicuous spots of the same color as integument, laterally with clear areas between the base of antennae and ocelli; frons dark brown medially, light yellow anteriorly, and with conspicuous spots of the same color as integument anterolaterally, extending laterally to base of antennae and anteriorly to ocelli; ocelli separated by approximately twice their width. Scape, pedicel, and flagellum dark yellow to black; maxillar and labial palpi uniformly dark yellow. Pronotum light yellow medially with wide lateral margins and narrow posterior margins dark brown ( Fig. 8View FIGURES 6 – 10). Meso– and metanotum with dark brown protuberances outlined in black. Legs dark brown ventrally with yellow spots medially; coxa and trochanter light yellow; femora anteriorly dark brown, posteriorly light brown with longer posteroventral bristles; tibia medially light yellow, without basal and apical brown spot. Fore– and hindwings with costal and distal areas infuscated with brown ( Figs. 9–10View FIGURES 6 – 10). Abdomen light yellow with margins of segments slightly darker; cerci dark brown with long lateral bristles and usually with last segment light yellow; sternum nine ( Fig. 26View FIGURES 26 – 35) wider than long with longer lateral and medial bristles, posterior margin projected medially; hammer ( Figs. 27, 28View FIGURES 26 – 35) rounded in ventral view, flattened in lateral view, approximately 0.1 mm long; paraproct ( Fig. 29View FIGURES 26 – 35) wider at base with longer bristles basally and medially and short subapical denticle. Aedeagus with a relatively short, truncate apex, without a keel ( Figs. 30–32View FIGURES 26 – 35). Penial armature with hooks short, folded forward ( Fig. 31View FIGURES 26 – 35).

Female. Similar in coloration to male ( Fig. 7View FIGURES 6 – 10). Sternum eight with four lobes, median notch deeper and paramedial lobes longer than lateral ones ( Fig. 33View FIGURES 26 – 35). Sternum nine with longer and denser submedian bristles and short median bristles extending anteriorly ( Fig. 34View FIGURES 26 – 35). Cerci brown. Vaginal sclerite membranous ( Fig. 35View FIGURES 26 – 35).

Nymphs. Unknown.

Eggs. Unknown.

Variations. Males vary in body length 4.9 –9.0 mm; frons color yellow to light brown; antennae color light to dark brown; anterior wing 6.9–8.3 mm long, 2.0– 2.6 mm wide; posterior wing 5.6–7.1 mm long, 2.4–3.1 mm wide; longitudinal and transversal vein color in anterior wing light to dark brown.
