compiled original distribution
records for hawkmoths (Lepidoptera: Sphingidae) from
Southeast Asia and Malesia and used them to estimate overall
geographic ranges for those species in the region. These maps
were used to estimate and analyse patterns of regional species
richness in the tropical, insular parts of the region (Beck et
al., 2006a), where regional species richness is high in the west
but low in the east.
