Species
Habitat and distribution
L. atriventris has arboreal habits, living and nesting on trees. On the other hand, L. picinus and L. valdiviensis are terrestrial species and have almost the same geographical distribution. The species have been found at Neuquén, Río Negro, Chubut and Santa Cruz provinces but only L. picinus reaches the southern tip of Patagonia at Tierra del Fuego. Despite the similarity in their geographical ranges, patterns of habitat use are thought to be different. L. picinus lives in humid areas of western Patagonia but it can penetrate more arid areas following the vegetation that grows along the rivers or where subterranean water makes the soil more humid. L. valdiviensis in turn, lives in more arid areas in the eastern part of the genus distribution. However, within the arid areas L. valdiviensis is thought to prefer sites with relatively humid soils.
