Bia rebeli Bryk, STAT. NOV. (Figs 1 c, 5, 6, 7, 11d, 12) Diagnostic re-description. General characters as described for the genus. Remarkably variable in all diagnostic characters that follow: (1) MF DFW white apical ocelli vary from medium to small and sometimes absent. (2) MF DFW orange band moderately wide but variable across range, usually opaque but diffuse in some specimens (e.g., Brazil, Amazonas, Arimã); orange scales can be somewhat extended proximally along veins, including the anterior tip of discal cell in some localities (e.g., Brazil, Amazonas, Tapajós), but not extended along veins in others (e.g., Bolivia). (3) M DFW iridescent band extremely variable, such as: limited to tornus; extending from anal margin to approximately half of the CuA2 cell; nearly reaching CuA2; and, less frequently, reaching CuA2. This band also shows some size variation within localities. F DFW iridescent band more diffuse and narrower than that of actorion, especially noticeable below CuA2 where the iridescence is less extended towards the tornus (more extended in actorion). (4) M DFW androconial scales on the CuA-CuA1-CuA2 intersection pale, contrasting scale color of surrounding area. (5) M DHW discal androconial pad varying geographically from chocolate-brown, to medium brown (silvery), or cream. (6) M DHW discal hairpencil varying geographically from chocolate-brown, to medium brown, or cream. (7) F VFW ripple pattern usually less dense than that of M, but some geographical and local variation was observed (see subspecies accounts). Male genitalia: tip of valva a narrow, rounded point that usually extends beyond the spiny projection (lateral view), spiny projection usually of medium height, infrequently tall; gnathos narrow, usually ending at a narrow point (lateral view); phallus narrowing towards tip. Type material. Holotype M (Fig. 1 c), deposited at the NRM collection, six labels separated by // and transcribed verbatim: PERU, Roque 26/4 1925 Douglas Melin // Bia actorion (L.) ssp. rebeli (m) // Typus // 23 // NRM Sthlm Loan 50/10. // NRM-01-10. The collecting locality is presumably in the San Martín Region, Lamas Province. Genitalia dissected and examined by TJS.

Geographical variation in all diagnostic characters serves as the basis for the subspecific classification proposed below.
