Bia actorion ecuatoria DeVries & Penz , NEW SSP.

( Figs 3 c–d, 10b, 12)

Diagnostic description. Defined by the following combination of characters: (1) MF DFW white apical ocelli medium-small (larger in F). (2) MF DFW orange band medium-wide; orange scales somewhat extended proximally along veins. (3) M DFW iridescent band from anal margin to approximately half of the CuA2 cell. F DFW blue iridescence well developed but variable; usually extended across the entire DC, diffuse anteriorly; usually visible at the CuA1-CuA2 intersection; below the discal cell, the iridescent area is wide and it spreads towards the tornus. F seems indistinguishable from actorion actorion . (4) M DFW androconial organ on the CuA- CuA1-CuA2 intersection dark brown, matching scale color of surrounding area. (5) DHW discal androconial pad chocolate-brown, comparable in color to the associated hairpencil. (6) M DHW discal hairpencil dark brown. (7) F VFW ripple pattern of the postmedial area clearly less dense than that of M.

Etymology. This taxon is named after the country of Ecuador.

Type material. Holotype M ( Fig. 3 c), deposited in the PJD collection, two labels separated by // and transcribed verbatim: Ecuador: Prov. Sucumbios, Garza Cocha—Anyañgu, 175km E.S. E. of Coca , 6 Aug 1993, P. DeVries, T. R. Walla & H. Greeny, Trap: 15 und // HOLOTYPE Bia actorion ecuatoria Penz & DeVries, 2017 . Paratypes are listed in Appendix, and Fig. 3 d shows a paratype F from the same locality as the holotype .

Distribution and examined specimens. Fig. 12 and Appendix.

Remarks. The dorsal hind wing androconial pads are paler than expected in two specimens collected in areas near Iquitos ( Peru; CMNH collection, Appendix), resembling those of rebeli . Photographs of specimens from Colombia, Leticia and San Vicente del Caguán provided by Gonzalo Andrade fit the description above (complete label data in Appendix).
