摘要
Based on nearly 2000 available records, the broadscale geographical distribution of the native earthworm fauna of Australia was mapped. Native earthworms were recorded from south-eastern, eastern and northern Australia within 400 km of the coast. Isolated faunas were present in Tasmania and south-west Western Australia, and apparently isolated faunas occurred in the Adelaide area/Fleurieu Peninsula of South Australia and the ranges of central Australia. All but 30 locality records occurred where annual rainfall averaged or exceeded 400 mm; 16 of these records were instances of moisture-gaining sites (moist caves, waterholes, banks of large rivers, edge of granite domes). A collecting strategy to both fill in gaps in the distribution map and discover additional anomalous occurrences (with respect to the 400 mm isohyet) is outlined.
