THE TACHINID TAXA OF PMESNIL,LOUIS, WITH NOTES ON NOMENCLATURE (INSECTA, DIPTERA)

Louis Paul Mesnil (1904-1986) wrote more than 90 published articles on the Tachinidae between 1936 and 1980. He proposed, in those works, a total of 172 new genus-group names and 838 new species-group names. Th ese genus-group and species-group names are listed here along with ann otations and a complete record of Mesnil's publications on the Tachini dae. Certain nomenclatural problems concerning the taxa of Mesnil are addressed, namely difficulties arising from the fascicle format of the series ''Die Fliegen der palaearktischen Region'', determination of t he type status of primary types (syntypes vs. holotypes), improperly l abeled types in collections, taxa described in cryptic fashion, type d epositories not stated or since changed, and manuscript names in colle ctions. The rules of the International Code of Zoological Nomenclature are followed to standardize usage of Mesnil's names.
