The males share the apex of the penis lobe rounded, and males and females share the forewing with costal and subcostal areas hyaline. Both species can be found in savanna areas in the RoraimaState, but the  U. passorumspecimens can be found at altitudes>300 meters above the sea level, while  U. flavopedescan be found in areas near 100 meters above the sea. The adults of  U. passorumare easily recognized by the presence of brownish wing bases. 1950907468 2014-11-01 UFRR Boldrini, R.
