E-mail: hdahners@gmx.de Abstract - Beatheclus beatrizae sp. n. is described on the basis of 50 male and 1 female specimens (type locality: 2200 m, San Antonio, Rio Aguacatal, Valle, Colombia). The new species has distinctive dorsal ground colour, ventral pattern and male genitalia. Beatheclus gen. n. (type species: Beatheclus beatrizae sp. n.) is erected on the basis of male genital and wing pattern characters, and is placed in the Panthiades Section sensu ROBBINS. With 13 figures and one table. Key words - South America, Eumaeini, Panthiades section, aedcagus, structural colour, new species, new genus. INTRODUCTION During extensive field work in Colombia a large lycaenid species was discovered in the San Antonio area of province Valle. It was immediately recognised that the species belongs to the Panthiades lineage of the Eumaeini, because of the wing pattern and dorsal forewing androconia. However, its generic placement aroused controversy: none of the genera of the Panthiades Section as defined by ROBBINS (2004: 277) offered a convincing solution. The male phenotype has a relatively large circular scent pad in the apex of the forewing discal cell like Michaelus phoenissa (HEWITSON, 1867) ROBBINS, 2004 (Figs 1-2), but the wing shape, dorsal ground colour, and ventral pattern diverge from Michaelus NICOLAY, 1979 (type species: Thecla vibidia HEWITSON, 1868). All the other Panthiades Section genera are more different in wing shape, colouration and pattern, or their combina-
