(Figs 1, 3O–R, 4M–P, 5D, 6)
Diagnosis. Males of I. mineirus sp. nov. (Fig. 3O–P) are most similar to I. fasciatus (Fig. 3E–F) due to the presence of three hyaline spots in the apical area of the FW and similar wing length. But, as noted in the diagnosis of I. fasciatus, the upper distal margin of the ampulla is concave in I. mineirus (Fig. 4M–N), while is rounded in I. fasciatus (Fig. 4E–F). For females, the distal third of the ductus bursae is enlarged with a somewhat larger, rounded signum (Fig. 5D), very different when compared to the other species (Fig. 5A–C).
Description. Male (Fig. 3O–P) — FW length: 11 mm to 13 mm. DFW: Presence of three hyaline spots in the apical area. Presence of one hyaline cell spot. HW length: 8 mm to 9 mm. VHW: Presence of cream-white scales most abundant near the marginal area. Genitalia (Fig. 4M–P): Uncus tapering to the distal region. Valva longer than wide, with an upper distal concavity in lateral view; sacculus about three times longer than wide, rectangular; harpe very narrow, approximately four times longer than wide, with similar width throughout its extension and making a curve upwards at its distal portion; ampulla with general aspect similar to harpe, darker, bearing small denticles on its distal margin. Aedeagus with a spined cornutus. Female (Fig. 3Q–R)—Differs from the male as follows: FW length: 13 mm. DFW: Brown with lighter and darker transverse bands, in some individuals the lighter bands are much more evident than on males (Fig. 3O–P). HW length: 9 mm. Presence of three small, white spots in the apical area, one hyaline cell spot, two additional spots can be present or absent, one between M 2 -M 3 and the other between M 3 -CuA 1. Genitalia (Fig. 5D): Lamella antivaginalis quadrangular in ventral view. Lamella postvaginalis as a semi-rounded plate. Distal third of ductus bursae enlarged, with a somewhat rounded signum.
Hostplants. No record.
Etymology. The epithet mineirus refers to the Brazilian word “mineiro”, which means a person born or inhabiting Minas Gerais (state of Brazil) where the type series was collected. The name is treated as a masculine noun in the genitive case.
