Diagnosis.
Rufocumbre emeryi
sp. nov.
is distinguished from all species of
Rufocumbre
by the uncus slightly bifid, with pointed arms; ampulla wider than base of valva, with the proximal margin pointed; distal spine of harpe shorter, not exceeding the distal margin of the ampulla (
Fig. 34
); lamella antevaginalis absent (as in
R. celioi
sp. nov.
); distal margin of the lamella postvaginalis with two long projections separated from each other by a short distance (
Fig. 39
).
Description.
Forewing length
: Male 13.9-17.5 mm, female 15.2-17 mm.
Forewing dorsal
(
Figs 5, 7
,
22
): brand with the inferior projection short.
Hind wing ventral
(
Figs 6, 8
): basal and postdiscal bands light orange, without gray to purple scales on the basal band; discal band separated from submarginal band by a short distance, with its distal margin angled.
Male genitalia
(
Fig. 34
): Uncus slightly bifid, with short and pointed arms; sacculus with about 1/5 of the width of valva, proximal margin close to the base of valva; ampulla wider than base of valva, proximal margin pointed; distal spine of harpe short, not exceeding the distal margin of ampulla; aedeagus about 2.3 times longer than the combined length of tegumen+uncus; aedeagus distal margin bifid, with divergent projections; cornutus as a small flattened plate with a short spine at the middle.

Female genitalia
(
Figs 39
,
44
): Lamella antevaginalis absent; distal margin of the lamella postvaginalis with two long projections separated from each other by a short distance; ductus bursae with an irregular sclerotized ring near the insertion with corpus bursae; corpus bursae with two weak lateral lines of signa, shorter than half of the corpus bursae.
Comments.
Rufocumbre emeryi
sp. nov.
was erroneously identified as
C. belli eberti
in surveys on the butterfly fauna from the Central Brazilian Plateau (
Pinheiro & Emery 2006
,
Mielke
et al.
2008
). Both species are easily distinguished by the presence of gray to purple scales on the ventral hind wing basal band of
R. eberti
stat. nov., comb. nov.
(
Figs 10, 12
). However, as this character may not be clearly seen in old or damaged specimens, the study of the genitalia is always needed. Males of
R. emeryi
sp. nov.
are distinguished from
R. eberti
(
Fig. 35
) by the shorter distal spine of harpe, never exceeding the distal margin of ampulla (
Fig. 34
), while the females of the former (
Fig. 39
) do not have the lamella antevaginalis, whereas it is present in
R. eberti
(
Fig. 40
).
Geographical distribution and phenology
. This species was recorded only in areas of Cerrado vegetation of the states of Mato Grosso, Goiás, Distrito Federal and Minas Gerais, between 350 and 1200 m (
Fig. 55
). Specimens were collected in January, April to July, and December.
Etymology.
This new species is named in memory of our friend the late Eduardo Oliveira Emery, in gratitude to his extensive support. Eduardo always kindly brought us with relevant information about the
Lepidoptera
fauna from Central Brazil, including specimens of
R. emeryi
sp. nov.
