whose distributions somewhat parallel the chilensis-species group include the well known Tigrinota "hairstreak" taxa binangula (Schaus) (temperate Peru/Argentina) and bolima (Schaus) (montane Parana). Similar distributions should be explored in ongoing work on the recently described hairstreak genus Bussa Johnson, Kruse and Kroenlein 1997. With incipient species including thargelia Burmeister (arid-temperate N Argentina and N Patagonian Steppe) and congeners west of the Andean divide northward in South America, additional members may be amongst undescribed species of montane eastern Brazilia. Of interest also is another "hairstreak" lineage, treated by lepidopterists either as Strymon sensu lato or Strymon plus several smaller-sized, drabber and tailless sister genera in the high Andes, Chile and Patagonia (Johnson, Miller and Herrera 1991, Benyamini and Johnson 1996). The prospect of montane Brazilian sisters of these latter groups should also be investigated. The question of an ancient Austral-South American fauna contributing part of the modern biota of the Andes and Patagonia has long fascinated lepidopterists. A classic enigma in this regard is the extremely primitive morphology of the pierid Colias ponteni Wallengren, whose original specimens, collected in the mid-19th century, may have come from the Magellanic steppe just north of Tierra del Fuego. As Johnson and Coates (1999) have generalized, and Shapiro (1991, 1993) recorded in detail, this butterfly, which may be one of the keys to understanding origins of the Austral-Antarctic butterfly fauna, has never since been collected. Pseudolucia is a genus which, among the polyommatines, also shows a distinctly southern South American distribution. Among the species groups of Pseudolucia the morphology of the chilensis-species group appears to be the most, or among the most, primitive. Thus, the discovery of the chilensis, parana, jujuyensis disjunction is of particular Zoogeographie interest. Acknowledgements — To Arthur M.
