Holotype ♀ (Figs 2a–b): Brazil – SC [Santa Catarina], Urubici, Santa Bárbara, 1360 m, 25.- 27.XII.2019, 28° 8’30.70’’ S, 49° 38’6.84’’ W, C. Mielke & E. Joerke leg./ 41.065 Col. C. Mielke / HOLOTYPUS, Agripialus variabilis C. Mielke, Grehan & Koike, 2021 / (DZUP). Paratypes (7♀). BRAZIL. Paraná: 2♀, Curitiba: 4.II.1975 (CGCM 15.404 (MGCL)); 18.II.1975, V. O. Becker leg. (CGCM 15.746 (CGCM)). Santa Catarina: 1♀, São Bento do Sul, Rio Natal, 4.IX.1999, A. Rank leg. (CGCM 7261 (CGCM)); 2♀, same locality and collector as the holotype, 1.–3.II.2019 (CGCM 38.744 (CGCM), CGCM 38.764 (DZUP)); 1♀, São Joaquim, 22–24.I.1983, 1400 m, V. Becker leg. (CGCM 15.036 (CGCM)). Rio Grande do Sul: 1♀, 28–31.I.2000, São José dos Ausentes, Silveira, 1200 m, A. Moser leg. (CGCM 3.652 (CGCM)). Diagnosis. Distinguished from its most similar species by differences in the shape of the subrectangular subanal plate, particularly the narrow lobate dorso-posterior corner, and the narrower (by about half) ductus bursae (Fig. 52). Description. Male. Unknown. Female (Figs 2–4, 21, 29, 32, 37, 52). Head. Antenna with ~42 antennomeres. Basal and distal labial palpomeres equal in length, second segment one and a half to two times longer. Thorax. Forewing length: 15–22 mm, wingspan: 35–45 mm. Wing ornamentation as shown in Figs 2–4. Genitalia (Fig. 52). Dorsal plates connected by thickened membranous cuticle or by a narrow sclerotised bar. Dorsal plate subrectangular with shallow convex lateral edge; shallow dorsal, ventral, and medial edges with lobe shaped dorsal corner. Lamella antevaginalis weakly sclerotized, in some cases with a ventrally oriented anterior tip. Subanal plate slightly sclerotised, subrectangular. Ductus bursae length subequal to corpus bursae. Geographical distribution. Known from southern Brazil in eastern Paraná, Santa Catarina and northeastern Rio Grande do Sul at altitude ranging from 800 to 1400 m (Figs 58, 62). Host plants. Unknown. Etymology. The proposed specific name alludes to variation in the ornamentation of the forewing dorsally (Figs 2a, 3–4). It is treated as an adjective in the nominative singular.
