U. amajari sp. nov. has a forewing coloration and penis shape similar to that of the widespread species U. uruguayensis (Traver) but it differs from the latter by the shape of the penis lobe apex in the male imago and by the lines of pectinate setae on the ventral surface of tibia III, in the nymph.
