Annotated catalogue of the Tachinidae (Insecta, Diptera) of Chile.

Abstract

The Tachinidae (Diptera) of Chile are catalogued and information is given on distributions, name-bearing types, synonyms, nomenclatural issues, and pertinent literature. The history of tachinid collectors in Chile and authors who have contributed to the systematic knowledge of Chilean tachinids is extensively reviewed. The classification has been updated and 122 genera and 264 species are recognised in Chile. There is a significant amount of endemism with 28 genera and 100 species known only from Chile. There are also 113 species with distributions shared only between Chile and Argentina, particularly in the southern portions of these countries comprising Patagonia.The catalogue is based on examination of the original descriptions of all nominal species and all other references known to us containing relevant taxonomic and distributional information, for a total of approximately 450 references. Many of the name-bearing types and other Chilean specimens housed in collections were examined. Taxa are arranged hierarchically and alphabetically under the categories of subfamily, tribe, genus, subgenus (where recognised), and species. Nomenclatural information is provided for genus-group and species-group names, including lists of synonyms (mostly restricted to Neotropical taxa) and name-bearing type data. Species distributions are recorded by country within the New World and by larger geographical divisions in the Old World. Additional information is given in the form of notes and references under valid names at the level of tribe, genus, and species. Two genera are newly recorded from Chile: Chaetoepalpus Vimmer & Soukup, 1940 (Tachinini) (also newly recorded from Argentina) and Patelloa Townsend, 1916 (Goniini). Four species are newly recorded from Chile or other countries: Lyphaornata Aldrich, 1934 (Chile); Chaetoepalpuscoquilleti Vimmer & Soukup, 1940 (Argentina and Chile); Phytomypteraevanescens (Cortés, 1967) (Argentina); and Xanthobasisunicolor Aldrich, 1934 (Chile). Eight species previously recorded from Chile are deemed to have been misidentified or misrecorded from Chile (known distributions in parentheses): Archytasincertus (Macquart, 1851) (Argentina, Brazil, Paraguay, Uruguay); Archytasseminiger (Wiedemann, 1830) (Brazil, Colombia); Goniacrassicornis (Fabricius, 1794) (Brazil, Peru, Venezuela, Middle America, West Indies, Nearctic); Lespesiaandina (Bigot, 1888) (Cuba); Lespesiaarchippivora (Riley, 1871) (widespread Nearctic and most of Neotropical); Neoethillaignobilis (van der Wulp, 1890) (Mexico, United States); Siphona (Siphona) geniculata (De Geer, 1776) (Palaearctic, Nearctic [introduced]); and Winthemiaquadripustulata (Fabricius, 1794) (Palaearctic, Nearctic, Oriental]. As First Reviser we fix Paratheresiarufiventris Townsend, 1929 as the senior homonym and Sarcoprosenarufiventris Townsend, 1929 as the junior homonym when the two are placed together in Billaea Robineau-Desvoidy, 1830; and we fix Mayophoriniaangusta Townsend, 1927 as the senior homonym and Metarrhinomyiaangusta Townsend, 1927 as the junior homonym when the two are placed together in Myiopharus Brauer & Bergenstamm, 1889. New replacement names are proposed for eight preoccupied names of Neotropical species (country of type locality in parentheses): Billaearufescens O’Hara & Wood for Sarcoprosenarufiventris Townsend, 1929, preoccupied in the genus Billaea Robineau-Desvoidy, 1830 by Paratheresiarufiventris Townsend, 1929 (Peru), nom. nov.; Billaeatriquetrus O’Hara & Wood for Sarcoprosenatriangulifera Townsend, 1927, preoccupied in the genus Billaea Robineau-Desvoidy, 1830 by Dexiatriangulifera Zetterstedt, 1844 (Peru), nom. nov.; Eucelatorianudioculata O’Hara & Wood for Eucelatorioideanigripalpis Thompson, 1968, preoccupied in the genus Eucelatoria Townsend, 1909 by Chetolyganigripalpis Bigot, 1889 (Trinidad), nom. nov.; Eucelatoriaoblonga O’Hara & Wood for Urodexodeselongatum Cortés & Campos, 1974, preoccupied in the genus Eucelatoria Townsend, 1909 by Exoristaelongata van der Wulp, 1890 (Chile), nom. nov.; Lespesiathompsoni O’Hara & Wood for Sturmiopsoideaobscura Thompson, 1966, preoccupied in the genus Lespesia Robineau-Desvoidy, 1863 by Eurigasterobscurus Bigot, 1857 (Cuba), nom. nov.; Myiopharuscharapensis O’Hara & Wood for Metarrhinomyiaangusta Townsend, 1927, preoccupied in the genus Myiopharus Brauer & Bergenstamm, 1889 by Mayophoriniaangusta Townsend, 1927 (Peru), nom. nov.; Myiopharusincognitus O’Hara & Wood for Stenochaetaclaripalpis Thompson, 1968, preoccupied in the genus Myiopharus Brauer & Bergenstamm, 1889 by Neoxynopsoideaclaripalpis Thompson, 1968 (Trinidad), nom. nov.; and Myiopharusrufopalpus O’Hara & Wood for Paralispepalpalis Townsend, 1929, preoccupied in the genus Myiopharus Brauer & Bergenstamm, 1889 by Myioxynopspalpalis Townsend, 1927 (Peru), nom. nov. New type species fixations are made under the provisions of Article 70.3.2 of the ICZNCode for three genus-group names: Parafabricia Brauer & Bergenstamm, 1894 (synonym of Archytas Jaennicke, 1867), type species newly fixed as Parafabriciaperplexa Townsend, 1931; Tachinodes Brauer & Bergenstamm, 1889 (synonym of Archytas Jaennicke, 1867), type species newly fixed as Juriniametallica Robineau-Desvoidy, 1830; and Willistonia Brauer & Bergenstamm, 1889 (synonym of Belvosia Robineau-Desvoidy, 1830), type species newly fixed as Willistoniaaldrichi Townsend, 1931. Lectotypes are designated for the following four nominal species, all described or possibly described from Chile: Echinomyiapygmaea Macquart, 1851 (a valid name in the genus Peleteria Robineau-Desvoidy, 1830); Goniachilensis Macquart, 1844 (a junior synonym of Goniapallens Wiedemann, 1830); Masiceraauriceps Macquart, 1844 (a valid name in the genus Lespesia Robineau-Desvoidy, 1863); and Prosopochoetanitidiventris Macquart, 1851 (a valid name in the genus Prosopochaeta Macquart, 1851).
