PART II — A TAXONOMIC CATALOGUE OF THE ORIENTAL 



TACHINIDAE 



INTRODUCTION 



The Oriental Tachinidae described up till the latter part of the nineteenth century 

 were catalogued by Bigot (1892) and Wulp (1896) in their general catalogues of 

 Oriental Diptera, but up to now - in the present paper and in Crosskey (in press) - 

 have remained uncatalogued this century. The Bigot and Wulp works have been 

 long outdated and lack all but historical interest. A new catalogue has been an 

 outstanding need for some time in tachinid taxonomy in order to synthesize the 

 many hundreds of generic and specific names pertaining to Oriental Tachinidae 

 that have been published in the past 80 years, mainly by specialists such as Baranov, 

 Mesnil, Townsend and Villeneuve. 



The new catalogue here presented is based upon a study of very nearly all existing 

 primary types of Oriental tachinids that has been made over the past ten years, 

 and therefore embodies a complete re-appraisal of the classification of Oriental 

 forms. Compilation merely from existing literature would have been, in the 

 confused state of past taxonomy, almost worthless - particularly because of the 

 problems created by the quite excessive generic splitting of Townsend, and because 

 of the habit of earlier workers of describing so-called new species without due 

 regard to the work of their predecessors (as the result of which many names that 

 are really junior synonyms have masqueraded for a long time as valid names). 

 But study of the types has inevitably resulted in the finding that many nominal 

 species have, through lack of previous investigation, remained in inappropriate 

 genera and that many names (both generic and specific) must be sunk as new syno- 

 nyms. Consequently many unavoidable changes of nomenclature have had to be 

 made in order to catalogue the taxa in a manner that reflects modern ideas of 

 classification: a summary of the nomenclatural changes is given after the body of 

 the catalogue. 



A total of 228 genera and 725 described species are treated as valid, but it must 

 be appreciated that some of the specific names accepted as valid might prove to 

 by synonyms when their respective genera are thoroughly revised; in large and 

 difficult genera, for example Carcelia, it has not been feasible to study the male 

 genitalia of types and other material (essential for determining specificity) and 

 it therefore cannot be claimed that all cases of specific synonymy have necessarily 

 been discovered. Generic limits are, of course, very subjective and specialists
