Holotype: “Holotipo ♂ de Yungas de Palmar, 1.000 m., Bolivia, Zischka leg., 6. V. 1948, en la colección del Sr. Alberto Breyer, de Buenos Aires. Preparación de los órganos genitales N o Br. 49.” [not examined]
Diagnosis: This subspecies differs from the nominotypical (Figs. 1 B, 2D–F) in the larger size, expressed in wing span, a much darker ground colour of both, dorsal and ventral wing surfaces, slightly wavier submarginal lines, and fainter, more diffused postdiscal VFW lines, as well as in a slightly thicker uncus, thinner apex of the valva and less arched aedeagus.
Redescription (MALE): Head: eyes dark brown or black and densely hairy; labial palpi with long, dark brown scales and shorter, yellowish scales, concentrated on the inner side of palpi; antenna slightly shorter than half the costal FW margin, dorsal surface brown to blackish, underside slightly brighter, beige or yellowish, with scales generally covering the basal half of the antenna; club elongated, composed of 11 segments.
Thorax: brown, dorsally covered with long, copper-brown, hair-like scales; all segments of legs hairy with additional short black bristles, scales on tibia generally brighter than those on femur and tarsus, tibial spurs present.
Abdomen: densely covered with brown scales, similar to those on thorax.
Wings (Fig. 1 A): forewing length: 28 mm, wing shape same as in the nominate species; dorsal forewing (DF): dark brown, no androconial patch, hair-like scales in anal area, dorsal hindwing (DH): same as on DF, with long, hair-like scales covering basal and discal area; ventral forewing: slightly brighter than DF, postdiscal line faint, arched, disappears on the vein M3, submarginal line diffuse, with semicircular curves, disappears on CuA2, marginal line thin, parallel to the wing margin, four pale yellow subapical dots; ventral hindwing: color same as DH; discal line faint and diffuse, almost straight, only softly arched in radial area, postdiscal line diffuse, arched and softly wavy, submarginal line with semicircular curves, not touching the marginal line; marginal line thin and softly wavy, five pale yellow submarginal dots, not touching the submarginal line.
Genitalia (Fig. 2 A–C): valva rhomboid, with a distinct, semicircular lateral process, apex elongated, pointed dorsally, uncus long, beak-shaped, slightly arched, saccus shorter than uncus, arched; aedeagus thin and very slightly arched in the middle.
FEMALE: So far unknown.
Geographical range: Only known from the eastern slopes of the Andes in northern Bolivia: Cochabamba Department, Carrasco Province (Yungas de Palmar, Villa Tunari via Locotal, Yendo a Chocolatal, Villa Tunari via Cochabamba).

Remarks. F. inornata species presents a widely disjunctive distribution. It is reported from the two extremes of tropical Andes, and is not found in the central Andes between south–central Ecuador and Bolivia, except for the two aforementioned, unconfirmed reports from central Peru. In most cases of such an “aberrant” distribution pattern the arising question is whether a disjunction is a fact or, simply, if the intermediate areas have been sampled enough for butterflies. In this case, we may rather convincingly rule out the latter hypothesis. Extensive field research have been carried out throughout Peru for at least three decades, and much attention has been dedicated to cloud forest satyrines. F. inornata is not an uncommon butterfly wherever it occurs, and hardly ever passes unnoticed. It is not the only species of Andean montane satyrine with such a widely disjunctive pattern, although admittedly the only one within the genus Forsterinaria. A similar distribution case was uncovered recently for Eretris mendoza Pyrcz, described from extreme northern Peru (Pyrcz, 2004) and recently discovered from central Bolivian Yungas in the Cochabamba province (Pyrcz, in prep.). More examples are known for the species of Pronophilina satyrines, including Thiemeia Weymer, Lasiophila C. & R. Felder, Steremnia Thieme and Pedaliodes Butler (Pyrcz, op. cit.).
Prior to this study, the taxonomic status of F. inornata magdalena was discussed and changed twice (Forster 1964, Peña & Lamas 2005). In both cases the considerations were based on the study of a single specimen, a different one in each case. The specimen examined by Peña & Lamas (op. cit.) was collected in late XIX century (1888–89) and, has most likely faded, thus loosing its distinctive darker coloration, and leading the authors to the conclusion that both subspecies are synonymous. This study, based on a series of specimens confirms Forster’s judgment.
Peña & Lamas (op. cit.) indicate that Hayward’s holotype of Euptychia magdalena, is deposited in the collection of Alberto Breyer in Buenos Aires. Although the collection of A. Breyer is indeed deposited in the Universidad Nacional in La Plata,, the type specimen of E. magdalena is not there (E. Nuńez-Busto, pers. comm.). Our research did not reveal its presence in any other major collections in Argentina, including the Institute of Miguel Lillo (Tucumán) (E. Perez, pers. comm.) and the Museo Argentino de Ciencias Naturales ¨Bernardino Rivadavia¨ (Buenos Aires), nor in the Natural History Museum (London). It is therefore currently missing. We could not determine, however, that it is actually destroyed, therefore we abstain from naming a Neotype here. Nevertheless, such an action will most probably be needed. In that case, the topotypical specimen deposited in Munich which possesses identical labels as the holotype (except for the collection date and the elevation, changed from originally printed ‘1000 m’ to hand written ‘2000 m’) should be designated as the Neotype.
