Diagnosis. Forewing length, male: 10–11mm; female: 11–12mm (n=10) ( Figs 7–10 , 25 ). Easily distinguished from other species of the genus by the presence of two orange bands on the forewing: a proximal band, from costal margin to the end of discal cell; and a distal band, extending diagonally from the costal margin to the outer margin close to the tornus. Stichelia dukinfieldia presents an additional orange band on the hindwing. Male genitalia ( Figs 33–34 ) with the ventral projection of the tegumen and the dorsal projection of the saccus slightly curved, uncus rectangular and angular in lateral view; projections of the gnathos closer to each other than other species of the “ bocchoris ” species group; pedicel thin in ventral view; aedeagus slender than other species of the genus; anterior projection of the saccus bilobed as in S. bocchoris ; ventral lobe of the valve of about the same size as the dorsal lobe. Female genitalia ( Figs 42–44 ) with lamella postvaginalis arched as in S. bocchoris ; ductus bursae straight, but slightly curved before the corpus bursae; signa absent (n = 3).

Taxonomic comments. Schaus (1902) described this species based in an unknown number of specimens from Castro, Paraná, Brazil, although he provides a voucher number for the type, No. 5904 (USNM). However, there are four additional specimens, three males and one female, from the same locality and with the same voucher number, and a female specimen with the same voucher number, but from an unknown locality in the state of São Paulo, Brazil deposited at the USNM. To avoid future confusion and assure the stability of the type location (ICZN 1999), a male specimen from Castro, illustrated by Warren et. al. (2013) and deposited in the type collection of the USNM, is here designed lectotype, and the three remaining specimens from Castro are designed paralectotypes. The female specimen from São Paulo is not considered to be part of the type series: it is not cited by Schaus (1902) in the original description, even though it bears the same voucher number and probably was used to describe the species. Apparently this species closest ally is S. bocchoris , as S. dukinfieldia also have orange scales on the pleura of the last abdominal segments; male genitalia with the anterior projection of the saccus slightly bilobed, and female genitalia with lamella post-vaginal arched.

Distribution. Occurs exclusively in open environments in the states of Bahia to Rio Grande do Sul, Brazil, at elevations above 800m ( Fig. 51 ). As S. bocchoris , most individuals (circa 93%) were recorded between December and March (n = 80).

Type material. The lectotype of Charis dukinfieldia Schaus, 1902 , here designated, has the following labels: / Castro, Parana[, Brazil]/ Collection W. Schaus/ Charis dukinfieldia type Schaus/ Type No. 5904 U.S. N.M./ LECTOTYPE Charis dukinfieldia Schaus, 1902 , Dias, Dolibaina, Casagrande & Mielke det. 2013/ LECTOTYPUS / (deposited at USNM). The characteristic lectotype label will be sent to the curator of the collection.
