    Abstract

    Results of a 13-day field survey of butterflies in the Darwin - Katherine - Kakadu area in 2008 are compared with existing synoptic maps and a private national database of butterfly records. Ten records of four species are beyond distributions previously mapped for them. The most substantial extensions (> 200 km) are for a species ('Cephrenes augiades') that may be expanding its range and another ('Nacaduba biocellata') that may be subject to large-scale seasonal irruptions. The Darwin - Katherine - Kakadu area has been moderately surveyed by Australian standards but has only one record of each species per 3,700 km2. Whilst it is likely that national synoptic maps of species' distributions represent the ranges of most species reasonably accurately, much remains to be learnt about butterfly distributions in the region.
