FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LXII 2001 pp. 151-165 Species descriptions and miscellaneous notes on the genus Pseudolucia (Lepidoptera: Lycaenidae) Zs. Bálint, D. Benyamini and K. Johnson Species descriptions and miscellaneous notes on the genus Pseudolucia (Lepidoptera: Lycaenidae) — Three polyommatinc lycaenids Pseudolucia kechico sp. n. (Chile, Reg. Aysen), Pseudolucia henyah sp. n. (Chile, Reg. Metropolitana) and Pseudolucia arauco sp. n. (Chile, Reg. Araucania) are described. A lectotype for Pseudolucia andina (Bartlett-Calvert, 1893) is designated. The male of Pseudolucia magellana Benyamini, Bálint et Johnson, 1995 and the female of Pseudolucia patago (Mabille, 1899) are recorded and figured for the first time. The type locality of Pseudolucia charlotte Bálint et Johnson, 1993 is corrected and restricted. With 35 original figures. Key words: Neotropics, Argentina, Chile, Polyommatini, Pseudolucia. INTRODUCTION The butterfly fauna of Chile recently received thorough study (Pcna & Ugarte 1997). In the introduction to that study, Lamas (1997: 18) suggested there might be little chance for discovering additional new species. However, as field work reached into hitherto unexplored areas of Chile, and more material became available from this geographically complex region, the peculiarity of the genus Pseudolucia Nabokov, 1945 in Chile became more and more obvious. Across South America's southern cone, the genus reveals a high diversity of species, mirroring the highly specialized niches available in the region's oreal biome because of microclimatic and edaphic conditions. This phenomenon also typifies the Holarctic lycaenid fauna where the genera Aricia Reichenbach, [1819], Plebejus Kluk, 1780 and Polyommatus Latreille, 1804 show similar high diversity in the oreal biome of the Northern Hemisphere. As a further contribution to the knowledge of the oreal lycaenid fauna of South America we have prepared this paper for (1) description of three new species, (2) supplementary descriptions of two species hitherto known from a single sex, and (3) designation of a (i) lectotype for Pseudolucia andina (Bartlett-Calvert, 1893) and (ii) type locality restriction for Pseudolucia charlotte Bálint et Johnson, 1993. These latter serve nomenclafural stability and taxonomic clarity.
