Praeacrospila patricialis is a moth in the family Crambidae. It was described by William Schaus in 1912. It is found in Costa Rica.[1]
The wingspan is about 34 mm. The forewings are pale yellow and thinly scaled, the costa shaded (darkest at the base). There is a fuscous basal spot on the costa and a subbasal spot in the cell, as well as an antemedial, wavy, oblique, fuscous line, followed by a small annular spot in the cell. The submedian is brownish and a short line is found medially below it to the antemedial. There are two dark lines at the end of the cell, connected with the postmedial by a single line. The terminal area from the postmedial is more heavily scaled and purplish brown, enclosing a small yellow spot close to the postmedial below vein 2 and one on the inner margin. The hindwings are semihyaline pale yellow, shaded with brown at the apex. There is a postmedial dark lunular line from the costa to vein 2.[2]
