based on Australian type-species, as the latter are listed with their type-localities 
in the catalogue of species that accompanies each generic (or subgeneric) 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 fulviventris 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 S.A. South Australia 
N.S.W. New South Wales Tasm. Tasmania 
NA. Northern Territory Vict. Victoria 
OLD Queensland W.A. Western Australia 
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), Nom. 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
