based on Australian type-species, as the latter are listed with their type-localities 

 in the catalogue of species that accompanies each generic (or sub-generic) name. 



Geographical distribution. An attempt has been made to provide a brief 

 synopsis of the known distribution of each species listed as valid in the catalogue. 

 Geographical data is given to the level of state or territory for Australia itself, 

 and to the level of island(s), country or zoogeographical region, as appropriate, 

 for species that occur extra-limitally as well as in Australia. Australian 

 distribution is given first, with the states listed alphabetically, followed by 

 extra-limital distribution (if any); the extra-limital distribution is listed with the 

 areas closest to Australia (e.g. New Guinea) first and more distant areas afterwards. 

 If there is only doubtful evidence of the occurrence of a particular species in any 

 Australian state, or if a published record from a state appears suspect, then the 

 state(s) in question are listed at the end of the Australian distribution and are 

 followed by a query mark: for example, Blepharipa fulviventns is recorded as 

 from 'N.S.W., QLD, TASM. (?)', this format indicating that records from New 

 South Wales and Queensland are considered confirmed but from Tasmania 

 doubtful (if records from two or more states are doubtful then a query mark 

 follows the entry for each such state) . The abbreviations used for listing Australian 

 states and territories are as follows: 



A.C.T. Australian Capital Territory 



N.S.W. New South Wales 



N.T. Northern Territory 



Qld Queensland 



Lord Howe Island is listed separately from New South Wales and is not 

 abbreviated. 



Nomenclatural changes. It has been necessary to establish in the catalogue 

 several new generic and specific synonymies, many new combinations for 

 generically re-assigned species, and a few new names for preoccupied homonyms: 

 a summary of these changes is provided on p. 157. The usual bold-face 

 abbreviations have been used to signify these changes, viz. Comb. n. (new 

 combination), Norn. n. (new name) and Syn. n. (new synonym). New combinations 

 are only marked as such when considered taxonomically valid; species-group 

 names that are assigned for the first time to a particular generic taxon are not 

 marked as new combinations if they are also junior synonyms (as in these instances 

 there are no valid new binomina in use) . The abbreviation Comb. n. when given 

 is placed after the type-locality data (which concludes the essentially nomenclatorial 

 matter) and before the distributional data in the body of the catalogue, and each 

 new taxonomically valid binomen is set out formally in the summary of new 

 combinations (p. 158). 



Miscellaneous annotations. Whenever it is necessary or desirable to call 

 attention to some specially pertinent point concerning a species-group name 

 appearing in the catalogue (e.g. to elucidate points of homonymy, possible
