Fittkauneuria adusta Pescador & Edmunds 1994: 268 View in CoL .

The genus was described for two species, one of them known from nymphs and male imagos, and the other only from nymphs. The species collected in this study is known only from nymphs.

Material. Venezuela, Edo Bolívar, Kamoirán river , 5º37’12’’N – 61º21’47’’W, 1313 m GoogleMaps , 23/XI/2005, 1 nymph. Tarotá stream, 5º49’15’’N – 61º25’04’’W, 1324 m GoogleMaps , 27/ VI /2007 , 3 nymphs. Specimens were deposited at the MLBV ( Venezuela) and IBN ( Argentina).

Discussion. The nymphs of F. adusta can be characterized by the abdominal gills, in which the dorsal lamellae is ovate, and the ventral tuft is vestigial. From the distribution of its two species, it appears that the genus is restricted to northern Amazonia and Venezuelan highlands.

Distribution. Brazil and Venezuela.

Ecology. Individuals were collected during the rainy season, in partially shaded small and medium size streams, both having a rock-bottom and acidic waters (pH=5).
