Cumbre belli eberti [misidentification]; K. Brown & Mielke, 1967. Jour. Lep. Soc. 21: 166. Cumbre sp. n.; Dolibaina; Mielke & Casagrande, 2011. Biota Neotrop. 11 (1): 345.

Diagnosis. This species is distinguished from all the other species of Rufocumbre by having the uncus widely bifid, with the arms extremely narrowed; proximal margin of ampulla not projected; distal projection of harpe exceeding the distal margin of ampulla by a short distance (Fig. 36); lamella antevaginalis widely bifid, with narrow projections, and a patch of membrane in the middle (Fig. 41).

Description. Forewing length: Male 15.5–17.2 mm, female 14.2–17 mm.

Forewing dorsal (Figs 13, 15, 24): brand with the distal margin of the superior projection irregular near the middle, and the inferior projection angled; ellipsoid cream spot on 2A, at the center of 2A, developed in both sexes.

Hind wing ventral (Figs 14, 16): basal and postdiscal bands dark orange, without gray to purple scales on the basal band; postdiscal band very short in Rs-M1.

Male genitalia (Fig. 36): Fenestra semicircular and large; uncus widely bifid, arms parallel to gnathos, narrow, about 1/3 the width of the gnathos arm, tip pointed; ampulla with the proximal margin not projected, and dorsodistal margin with a small tip; distal spine of harpe larger and less pointed than in other species, short, exceeding the distal margin of ampulla by a short distance; aedeagus distally bifid, with convergent and unequal projections; cornutus absent.

Female genitalia (Figs 41, 46): Lamella antevaginalis widely bifid from base, with narrow and divergent projections, and a patch of membrane at the middle of each projection; lamella postvaginalis distally bifid, with large and convergent rounded projections; ductus bursae smooth at the insertion with corpus bursae; corpus bursae with two long and large lines of signa, extending for almost all its extension, each line medially crossed by a narrow and smooth area.

Comments. This species is very similar and potentially sympatric with R. celioi sp. nov. (Figs 1–4). Both species were collected in adjacent areas in Paraná state (Figs 54, 56); however, unlike the situation for R. celioi sp. nov., R. schneideri sp. nov. is known from few and sparse records from Tocantins to Paraná (Fig. 56), with just one specimen collected for each locality (with the exception of Sobradinho, Brasília, Distrito Federal where a male and a female were collected in 1966 and 1968, respectively). The males of R. schneideri sp. nov. are readily distinguished from those of R. celioi sp. nov. by the developed brand on the dorsal forewing (Fig. 24) and by the deeply bifid uncus with narrow arms (Fig. 36). Females are easily separated by the presence of the lamella antevaginalis in R. schneideri sp. nov. (Fig. 41) whereas it is absent in R. celioi sp. nov. (Fig. 38), a character easily observable in dry specimens after removing the scales of the tip of the abdomen (dissection is not required).

Brown & Mielke (1967) listed this new species as Cumbre belli eberti from Central Brazil Plateau (specimen from Sobradinho, Brasília), while Dolibaina et al. (2011) mentioned it as Cumbre sp. n. from Guarapuava region, Paraná.

Geographical distribution and phenology. Rufocumbre schneideri sp. nov. is known from a few records from Tocantins, Distrito Federal, Minas Gerais and Paraná, in areas between 200 and 1365 m (Fig. 56). Specimens were collected in January, February, March, May, October and December.

Etymology. This new species is dedicated in memory of our friend the late Hipólito Schneider, an amateur insect collector that lived in Guarapuava, Paraná, whose work inspired the first author to study Lepidoptera .
