Bia rebeli acreana Casagrande & Penz , NEW SSP.

( Figs 6 a–b, 10h, 12)

Diagnostic description. Defined by the following combination of characters: (1) MF DFW white apical ocelli small. (2) MF DFW orange band moderately wide, opaque, orange scales somewhat extended proximally along veins. (3) M DFW iridescent band not reaching CuA2, and appearing less intense than in other taxa. F DFW iridescent band less intense and of a paler hue; this band is narrower and shorter than that of other rebeli subspecies, extending less than half the height of the discal cell and not reaching the tornus. (4) M DFW androconial organ on the CuA- CuA1-CuA2 intersection pale, contrasting scale color of surrounding area. (5) DHW discal androconial pad cream-colored. (6) DHW discal hairpencil brown, darker than scales of the associated androconial pad. (7) F VFW ripple pattern slightly less dense than, or similar to, that of M.

Etymology. This subspecies is named after the Brazilian state of Acre.

Type material. Holotype M ( Fig. 6 a), deposited in the DZUP collection, four labels separated by // and transcribed verbatim: HOLOTYPUS // 23–30-VIII-2014, Rio Moa , P [ar]q.[ue] Nac.[ional] Serra do Divisor (Séde), Mâncio Lima, Acre, Brasil . Mielke, Casagrande, Carneiro, Dias, Dolibaina, Siewert & Salik leg. 7°26’52’’S. 73°30’55’’// DZ 32.591 // Holotypus Bia rebeli acreana Casagrande & Penz, 2017 . Paratypes are listed in Appendix, and Fig. 6 b shows a paratype F.

Distribution and examined specimens. Fig. 12 and Appendix.

Remarks. The dorsal hind wing discal androconial pad of rebeli acreana ( Fig. 10 h) is as light as that of rebeli rebeli ( Figs 1 c, 6a), but the hairpencil of the latter seems to be lighter in color. These two subspecies are allopatric. The male dorsal forewing orange band of rebeli acreana is more similar to rebeli aegina than to rebeli arikeme and rebeli pareci .
