TACHINIDAE OF AUSTRALIA 101 
systematic order within subfamilies (rather arbitrary positional placements being 
made for the more aberrant tribes). Genera, subgenera and species treated as 
valid are listed alphabetically within their higher category, as there is no accepted 
systematic order for their placement. Nomenclatorial synonyms are listed 
chronologically under their respective valid names. Incorrect subsequent spellings 
and misidentifications are listed after the nomenclatorial synonyms (if any), and 
each entry of a misidentification is placed in square brackets. 
CITATION OF NAMES AND REFERENCES. In each entry the name (generic, 
subgeneric or specific) is cited first, followed by its author and date of publication 
and the page reference to the work in which the name appeared; the author, year 
date (letter-suffixed if more than one work by the same author in any year), and 
page are always sufficient for obtaining the complete reference to the work containing 
the name from the bibliography. Where a work is best known from a separately 
paginated reprint version the reprint page reference is given in parentheses 
immediately after the journal page reference. 
The name of the original genus to which any species-group name was assigned 
when first published is shown in parentheses immediately after the page reference, 
but only when different from the present generic assignment (if no generic name 
follows the page reference it is always to be inferred that the species-group taxon 
in question was originally placed in the same genus as that in which it is here 
listed). It is always clear from this convention whether or not any species remains 
in its original genus, and parentheses have intentionally not been placed around 
the authors’ names for those species that are no longer in their original genera 
(mainly because the custom of bracketing around the names of authors of transferred 
species does not lend itself to this type of catalogue in which both year date and 
page reference are given). 
Spellings of names accord with the rigid requirements of the International Code 
of Zoological Nomenclature. Ordinarily the original spelling is the correct one 
for each name, but as a few of the Australian tachinid genera have a neuter gender 
(e.g. the names ending in -stoma and -soma) it has sometimes been necessary to 
change the endings of adjectival specific names associated with such generic 
names (to accord with Article 30 of the Code). For example, most species here 
placed in Senostoma were originally described in genera with feminine gender 
and the names originally had feminine endings; on being brought into combination 
with Senostoma (neuter) the endings have had to be changed appropriately. 
(Here it may be noted that I have no personal sympathy with Article 30, which 
imposes an unnecessary burden on zoological nomenclature.) In some instances 
a specific name when first published was associated with an incorrect subsequent 
spelling of a generic name: when it appears helpful to do so, the incorrect spelling 
is cited in parentheses after the page reference even though the species in question 
remains in the same genus. 
Citations of the mode of fixation of type-species accord with the Code, and are 
‘original designation’, ‘monotypy’, and ‘subsequent designation’ (with a reference 
to the designator given). Many monotypic genera when originally erected had
