Adult habitus. General color dark brown patterned with yellow. Anterior third of head yellow, posterior region dark brown; dark area with a small median emargination on anterior margin ( Fig. 50View Figs). Pronotum mostly dark but with a median, yellow V-shaped area. Wings brown, veins darker. Femora banded, pale at base and dark apically; foreleg yellow band reduced, hind leg yellow band subequal to dark.

Female. Forewing length 9.5 mm. Subgenital plate weakly 4-lobed; inner lobes separated by V-shaped notch, lateral lobes separated by shallow emarginations ( Fig. 51View Figs). Transverse sclerite of sternum 9 weak, but armed on posterolateral margins with small patch of strong setae; mesal setal patch with well defined lateral patches consisting of mixed setae and median stalk of short, fine setae.

Egg. Spindle shaped but much shorter and wider than typical Anacroneuria  eggs ( Fig. 52View Figs).

Discussion. The Brazilian specimen shares the leg and pronotal patterns but has a slightly different head pattern. The subgenital plates also differ slightly but the setal patterns of sternum 9 are very similar. The collection locality belongs to the Región Natural Amazónica in lowlands of Río Amazonas central basin. The water of the small streams is slightly colored by soluble organic compounds such as tannins and lignins from the flooded forest in this area. Water temperature at the time of collection was 23°C and the air 26°C.
