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.
