SYNOPSIS 
A comprehensive re-classification is proposed for the Rutiliini, a Tachinid tribe confined to the 
Oriental and Australasian Regions. Diagnoses and identification keys are provided for all 
genera and subgenera recognized, and all nominal species are appropriately placed in the 
classification after examination of the types. Keys are given, under their respective genus-group 
taxa, to almost all of the 121 described species that are recognized as valid; it is emphasized 
that the species keys are only tentative, as species limits are often uncertain and several un- 
described species are known. ‘The proposed classification is summarized and an index-cata- 
logue is provided to all nominal species-group taxa and their primary types. One new genus, 
one new subgenus and seven new species are described; 47 specific names and 15 genus-group 
names are newly placed in synonymy; 29 lectotypes and 12 neotypes are newly designated; 
and one new name is proposed for a preoccupied secondary homonym. There are 26 new 
combinations (excluding those implied by new synonymy).
