MATERIALS AND METHODS The comparative material examined is listed in the Appendix. The following collection acronyms are used throughout the text: AMNH = American Museum of Natural History, New York (USA), BMNH = The Natural History Museum, London (United Kingdom), HNHM = Hungarian Natural History Museum, Budapest (Hungary), JFLC = private collection of JEAN FRANÇOIS LECROM, Bogotá (Colombia), MUSM = Museo de História Natural, Universidad Nacional Mayor de San Marcos, Lima (Peru); MZUJ = Zoological Museum of the Jagiellonian University, Krakow (Poland), PB = private collection of PIERRE BOYER, Aix en Provence (France) (will be donated to MZUJ), USNM = National Museum of Natural History, Smithsonian Institution, Washington DC (USA). Terminology used for androconia, genitalia and wing pattern morphology is after ELIOT (1973), ROBBINS (1991) and JOHNSON (1992). We examined only male genital structures, because "Penaincisalia' females are rare in collections, consequently the genital structures were not studied in such a wide array of taxa as in the case of males. More dissections have to be made in order to gain a better understanding of the female structures. This is out of the scope of the present paper. In the dissections of the genitalia standard techniques for Lepidoptera were used (WINTER 2000). After macerating the abdomen in a hot 10% KOH solution the fakes, aedeagus, valvae, vinculum, saccus, and dorsal capsule were separated and mounted in Euparal on slides, to examine them under optical microscope. The valvae were divided and positioned in lateral and ventral view, respectively. The adult images were taken with a digital camera (Nikon Coolpix 4500) and manipulated with Adobe Photoshop 7.0. The images of the genitalia structures were taken with the same camera attached to a Leica MZ12 stereo-microscope and a Leica DMRB microscope. DESCRIPTONS OF NEW SPECIES Penaincisalia amatamba PRIETO, BOYER, LECROM et BÁLINT, sp. n. (Figs 3-4, 11-12, 16, 19, 22) Type material - Holotype male, set dorsally, in perfect condition, labelled as: "Ecuador, Azuay/Morona Santiago, Chiguinda-sigsig, 2900/3500m, 03/12/98, leg. P. Boyer"; now in PB, will be deposited in MZUJ. Paratype: Ecuador, Cordillera Lagunillas, 3300m, XL 2000, leg. I. ALDAS (JFLC). Diagnosis - The species is placed in the balzapamba group of species sensu HALL etal. (2005) within "Penaincisalia" sensu ROBBINS (2004) on the basis of a large forewing scent pad situated in the apical part of the discal cell, a slender aedeagus, which is longer than the genital capsule and is at least 1 /4 of the total aedeagus length and the presence of a gray disc situated in the anal area of the hindwing ventral surface.
