Length of fore wing 10−11 mm . Antenna bipectinate, setae 1.5 times longer than antenna rod diameter. Fore wing brown, basally with wide dark-brown band, cubitally with bright round white spot, postdiscally with thin dark-brown band, submarginally with poorly noticeable blurred dark-brown small spots on brown background; fringe mottled, dark at veins, light between veins. Hind wing brown without pattern. Male genitalia . Uncus long, apically extended (spearhead-shaped); valve relatively long, oval, basally with long harpe which is apically crescent, its abdominal edge covered with tiny prongs; trapezoidal short harpe at abdominal edge of valve; saccus trapezoidal, apically blunt; phallus thin, crescent, apically thin, acute, vesica without cornuti. Female quite similar, bigger and brownish. No further differences. Female genitalia not dissected. Diagnosis . The new species clearly differs from the known species of the genus in the small size, the dark color, the crescent apices of the harpes on the basal edge of the valve and the thin apically acute phallus. Flight period . November−April. Distribution . Paraguay ( Alto Paraná , Cordillera and Concepción Department ), Argentina (Misiones Province). Etymology . Guarani are a group of culturally-related native indigenous peoples of South America. They are distinguished from the related Tupi by their use of the Guarani language. The traditional range of the Guarani people is in present-day Paraguay between the Uruguay River and lower Paraguay River, the Misiones Province of Argentina , southern Brazil once as far east as Rio de Janeiro , and parts of Uruguay and Bolivia .
