A world review of the bristle fly parasitoids of webspinners.

BACKGROUND: Dipteran parasitoids of Embioptera (webspinners) are few and extremely rare but known from all biogeographical regions except Australasia/Oceania. All belong to the fly family Tachinidae, a hyperdiverse and widespread clade of parasitoids attacking a variety of arthropod orders. RESULTS: The webspinner-parasitizing Diptera are reviewed based mostly on records from the collecting and rearing by Edward S. Ross. A new genus is erected to accommodate a new Afrotropical species, Embiophoneus rossi gen. et sp. nov. The genus Perumyia Arnaud is reviewed and a new species, Perumyia arnaudi sp. nov., is described from Central America while P. embiaphaga Arnaud is redescribed and new host records are given. A new species of Phytomyptera Rondani, P. woodi sp. nov., is described from Myanmar, representing the first report of a member of this genus obtained from webspinners. The genus Rossimyiops Mesnil is reviewed, R. longicornis (Kugler) is redescribed and R. aeratus sp. nov., R. fuscus sp. nov. and R. rutilans sp. nov. are newly described from the Oriental Region, and an updated key to species is given. CONCLUSIONS: Webspinners were probably colonized independently at least four times by tachinids shifting from other hosts, most likely Lepidoptera.

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

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 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).

Twenty years of Dipterology through the pages of Zootaxa.

We present a summary and analysis of the Diptera-related information published in Zootaxa from 2001 to 2020, with a focus on taxonomic papers. Altogether, 2,527 papers on Diptera were published, including 2,032 taxonomic papers and 1,931 papers containing new nomenclatural acts, equivalent to 22% of all publications with new nomenclatural acts for Diptera. The new nomenclatural acts include 7,431 new species, 277 new genera, 2,003 new synonymies, and 1,617 new combinations. A breakdown by family of new taxa and new replacement names proposed in the journal during the last two decades is provided, together with a comparison of Zootaxa's output to that of all other taxonomic publications on Diptera. Our results show that the journal has contributed to 20% of all biodiversity discovery in this megadiverse insect order over the last 20 years, and to about 31% in the last decade.

Diptera of Canada.

The Canadian Diptera fauna is updated. Numbers of species currently known from Canada, total Barcode Index Numbers (BINs), and estimated numbers of undescribed or unrecorded species are provided for each family. An overview of recent changes in the systematics and Canadian faunistics of major groups is provided as well as some general information on biology and life history. A total of 116 families and 9620 described species of Canadian Diptera are reported, representing more than a 36% increase in species numbers since the last comparable assessment by JF McAlpine et al. (1979). Almost 30,000 BINs have so far been obtained from flies in Canada. Estimates of additional number of species remaining to be documented in the country range from 5200 to 20,400.

Molecular phylogeny and evolution of world Tachinidae (Diptera).

We reconstructed phylogenetic relationships within the diverse parasitoid fly family Tachinidae using four nuclear loci (7800 bp) and including an exceptionally large sample of more than 500 taxa from around the world. The position of the earthworm-parasitizing Polleniinae (Calliphoridae s.l.) as sister to Tachinidae is strongly supported. Our analyses recovered each of the four tachinid subfamilies and most recognized tribes, with some important exceptions in the Dexiinae and Tachininae. Most notably, the tachinine tribes Macquartiini and Myiophasiini form a clade sister to all other Tachinidae, and a clade of Palpostomatini is reconstructed as sister to Dexiinae + Phasiinae. Although most nodes are well-supported, relationships within several lineages that appear to have undergone rapid episodes of diversification (basal Dexiinae and Tachininae, Blondeliini) were poorly resolved. Reconstructions of host use evolution are equivocal, but generally support the hypothesis that the ancestral host of tachinids was a beetle and that subsequent host shifts to caterpillars may coincide with accelerated diversification. Evolutionary reconstructions of reproductive strategy using alternative methods were incongruent, however it is most likely that ancestral tachinids possessed unincubated, thick shelled eggs from which incubated eggs evolved repeatedly, potentially expanding available host niches. These results provide a broad foundation for understanding the phylogeny and evolution of this important family of parasitoid insects. We hope it will serve as a framework to be used in concert with morphology and other sources of evidence to revise the higher taxonomic classification of Tachinidae and further explore their evolutionary history and diversification.

First fossil of an oestroid fly (Diptera: Calyptratae: Oestroidea) and the dating of oestroid divergences.

Calyptrate flies include about 22,000 extant species currently classified into Hippoboscoidea (tsetse, louse, and bat flies), the muscoid grade (house flies and relatives) and the Oestroidea (blow flies, bot flies, flesh flies, and relatives). Calyptrates are abundant in nearly all terrestrial ecosystems, often playing key roles as decomposers, parasites, parasitoids, vectors of pathogens, and pollinators. For oestroids, the most diverse group within calyptrates, definitive fossils have been lacking. The first unambiguous fossil of Oestroidea is described based on a specimen discovered in amber from the Dominican Republic. The specimen was identified through digital dissection by CT scans, which provided morphological data for a cladistic analysis of its phylogenetic position among extant oestroids. The few known calyptrate fossils were used as calibration points for a molecular phylogeny (16S, 28S, CAD) to estimate the timing of major diversification events among the Oestroidea. Results indicate that: (a) the fossil belongs to the family Mesembrinellidae, and it is identified and described as Mesembrinella caenozoica sp. nov.; (b) the mesembrinellids form a sister clade to the Australian endemic Ulurumyia macalpinei (Ulurumyiidae) (McAlpine's fly), which in turn is sister to all remaining oestroids; (c) the most recent common ancestor of extant Calyptratae lived just before the K-Pg boundary (ca. 70 mya); and (d) the radiation of oestroids began in the Eocene (ca. 50 mya), with the origin of the family Mesembrinellidae dated at ca. 40 mya. These results provide new insight into the timing and rate of oestroid diversification and highlight the rapid radiation of some of the most diverse and ecologically important families of flies.

Annotated catalogue of the Tachinidae (Insecta, Diptera) of the Afrotropical Region, with the description of seven new genera.

The Tachinidae of the Afrotropical Region are catalogued and seven genera and eight species are newly described. There are 237 genera and 1126 species recognized, of which 101 genera and 1043 species are endemic to the region. The catalogue is based on examination of the primary literature comprising about 525 references as well as numerous name-bearing types and other specimens housed in collections. Taxa are arranged hierarchically and alphabetically under the categories of subfamily, tribe, genus, subgenus (where recognized), species, and rarely subspecies. Nomenclatural information is provided for all genus-group and species-group names, including lists of synonyms (mostly restricted to Afrotropical taxa) and name-bearing type data. Species distributions are recorded by country within the Afrotropical Region and by larger geographical divisions outside the region. Additional information is given in the form of notes, numbering about 300 in the catalogue section.

Three genera are newly recorded from the Afrotropical Region: Madremyia Townsend, 1916 (Eryciini); Paratrixa Brauer & Bergenstamm, 1891 (Blondeliini); and Simoma Aldrich, 1926 (Goniini). Three genera previously recorded from the Afrotropical Region are no longer recognized from the region: Calozenillia Townsend, 1927 (Palaearctic, Oriental and Australasian regions); Eurysthaea Robineau-Desvoidy, 1863 (Palaearctic, Oriental and Australasian regions); and Trixa Meigen, 1824 (Palaearctic and Oriental regions). Two species are newly recorded from the Afrotropical Region: Amnonia carmelitana Kugler, 1971 (Ethiopia, Kenya); and Simoma grahami Aldrich, 1926 (Namibia). Three species previously recorded from the Afrotropical Region are no longer recognized from the region: Euthera peringueyi Bezzi, 1925 (Oriental Region); Hamaxia incongrua Walker, 1860 (Palaearctic, Oriental and Australasian regions); Leucostoma tetraptera (Meigen, 1824) (Palaearctic Region). New replacement names are proposed for five preoccupied names of Afrotropical species: Billaea rubida O'Hara & Cerretti for Phorostoma rutilans Villeneuve, 1916, preoccupied in the genus Billaea Robineau-Desvoidy, 1830 by Musca rutilans Fabricius, 1781, nom. n.; Cylindromyia braueri O'Hara & Cerretti for Ocyptera nigra Villeneuve, 1918, preoccupied in the genus Cylindromyia Meigen, 1803 by Glossidionophora nigra Bigot, 1885, nom. n.; Cylindromyia rufohumera O'Hara & Cerretti for Ocyptera scapularis Villeneuve, 1944, preoccupied in the genus Cylindromyia Meigen, 1803 by Ocyptera scapularis Loew, 1845, nom. n.; Phytomyptera longiarista O'Hara & Cerretti for Phytomyzoneura aristalis Villeneuve, 1936, preoccupied in the genus Phytomyptera Rondani, 1845 by Phasiostoma aristalis Townsend, 1915, nom. n.; and Siphona (Siphona) pretoriana O'Hara & Cerretti for Siphona laticornis Curran, 1941, preoccupied in the genus Siphona Meigen, 1803 by Actia laticornis Malloch, 1930, nom. n.

First North American record of the Palaearctic rhinophorid Stevenia deceptoria (Loew) (Diptera: Rhinophoridae).

The Rhinophoridae (Diptera) have a cosmopolitan distribution and a known fauna of about 150 species (Cerretti & Pape 2007). So far as known, all species are parasitoids of terrestrial woodlice (sow bugs) of the order Isopoda (Oniscoidea) (Pape 2010). Female rhinophorids lay eggs in the vicinity of potential hosts and the planidial first instars parasitize sow bugs as they pass by (Pape 1998).

The identity of Tachina westermanni Wiedemann, 1819 (Diptera: Calliphoridae or Tachinidae) with a solution to a nomenclatural problem.

Tachina westermanni Wiedemann, 1819 was based on four syntypes, two conspecific calliphorids and two conspecific tachinids. Two existing but contradictory lectotype fixations have resulted in confusion as to the correct application of the specific name westermanni Wiedemann. Evidence is presented showing that the lectotype fixation of Townsend in 1931 is valid and assigns westermanni Wiedemann to the Calliphoridae, with Pericallimyia westermanni as the valid binomen. The valid name for the tachinid taxon becomes Brachelia westermanni Robineau-Desvoidy, 1830 and a neotype is designated for it in the interests of nomenclatural stability.

Explosive radiation or uninformative genes? Origin and early diversification of tachinid flies (Diptera: Tachinidae).

Molecular phylogenetic studies at all taxonomic levels often infer rapid radiation events based on short, poorly resolved internodes. While such rapid episodes of diversification are an important and widespread evolutionary phenomenon, much of this poor phylogenetic resolution may be attributed to the continuing widespread use of "traditional" markers (mitochondrial, ribosomal, and some nuclear protein-coding genes) that are often poorly suited to resolve difficult, higher-level phylogenetic problems. Here we reconstruct phylogenetic relationships among a representative set of taxa of the parasitoid fly family Tachinidae and related outgroups of the superfamily Oestroidea. The Tachinidae are one of the most species rich, yet evolutionarily recent families of Diptera, providing an ideal case study for examining the differential performance of loci in resolving phylogenetic relationships and the benefits of adding more loci to phylogenetic analyses. We assess the phylogenetic utility of nine genes including both traditional genes (e.g., CO1 mtDNA, 28S rDNA) and nuclear protein-coding genes newly developed for phylogenetic analysis. Our phylogenetic findings, based on a limited set of taxa, include: a close relationship between Tachinidae and the calliphorid subfamily Polleninae, monophyly of Tachinidae and the subfamilies Exoristinae and Dexiinae, subfamily groupings of Dexiinae+Phasiinae and Tachininae+Exoristinae, and robust phylogenetic placement of the somewhat enigmatic genera Strongygaster, Euthera, and Ceracia. In contrast to poor resolution and phylogenetic incongruence of "traditional genes," we find that a more selective set of highly informative genes is able to more precisely identify regions of the phylogeny that experienced rapid radiation of lineages, while more accurately depicting their phylogenetic context. Although much expanded taxon sampling is necessary to effectively assess the monophyly of and relationships among major tachinid lineages and their relatives, we show that a small number of well-chosen nuclear protein-coding genes can successfully resolve even difficult phylogenetic problems.

A review of genus-group names in Diptera (Insecta) that J.C. Fabricius "borrowed" from other dipterists and proposed as new in his systematic works from 1775 to 1805.

It is shown that a total of eight pre-existing genus-group names in Diptera were "borrowed" and deliberately given new identities in the systematic works of J.C. Fabricius: Bibio Fabricius, 1775, Ceria Fabricius, 1794, Hirtea Fabricius, 1798, Mulio Fabricius, 1798, Scatophaga Fabricius, 1805, Sicus Fabricius, 1798, Thereva Fabricius, 1798 and Voluccella Fabricius, 1794. These names are reviewed from the standpoint that they are nomenclaturally available as intentional homonymous proposals of names for new genus-group taxa. New type-species designations are made for Bibio Fabricius, Mulio Fabricius, and Scatophaga Fabricius. Bibio Fabricius, 1775 is recognized as a senior synonym of Thereva Latreille, 1797, syn. n., but is invalid as it is a junior homonym of Bibio Geoffroy, 1762. Scatophaga Fabricius, 1805 is recognized as a junior synonym of Psila Meigen, 1803, syn. n. The nominal species Musca suilla Fabricius, 1794 has been misinterpreted as a species of Scathophaga Meigen, 1803 by subsequent authors. Scathophaga spurca Meigen, 1826 is revived as the valid name for Scathophaga suilla auct. nec (Fabricius, 1794), stat. rev. A lectotype is designated for Musca suilla Fabricius and it is shown to belong to the scathophagid Norellisoma spinimanum (Fallén, 1819), syn. n. In order to maintain stability of nomenclature and prevailing usage, reversal of precedence is invoked to declare Cordylura spinimana Fallén, 1819 as a nomen protectum and Musca suilla Fabricius, 1794 as a nomen oblitum. 

A new Loewia Egger (Diptera: Tachinidae) from Turkey, with taxonomic and nomenclatural remarks on congeners.

The new species Loewia papei sp. nov. from southern Anatolia (Turkey) is described, illustrated and compared with congeners. A brief diagnosis of Loewia Egger is provided and the systematics of the genus are discussed. Loewia nudigena Mesnil, 1972 is fixed as the type species of Fortisia Rondani, 1861 (junior synonym of Loewia). A full list of previously known valid species of Loewia is provided along with information on primary types, type repositories (where known), and type localities. A lectotype is designated for Thrychogena brevifrons Rondani, 1856 (= Loewia brevifrons (Rondani, 1856)).

Reassessment of Paleotachina Townsend and Electrotachina Townsend and their removal from the Tachinidae (Diptera).

The monotypic genera Paleotachina Townsend, 1921 and Electrotachina Townsend, 1938 were originally described as fossils in amber but were later discovered to be inclusions in copal. Both taxa were originally assigned to the Tachinidae (Diptera) and this placement has continued to the present day. The holotypes of the two type species, P. smithii Townsend and E. smithii Townsend, were examined and the following taxonomic and nomenclatural changes are proposed: Paleotachina is transferred to the Muscidae and placed in synonymy with Aethiopomyia Malloch, 1921, syn. n.; P. smithii Townsend, type species of Paleotachina, is synonymized with Aethiopomyia gigas (Stein, 1906), syn. n.; Electrotachina is transferred to the Sarcophagidae and placed in synonymy with Dolichotachina Villeneuve, 1913, syn. n.; E. smithii Townsend, type species of Electrotachina, is recognized as a valid species of Dolichotachina comb. n. Images of the holotypes of P. smithii and E. smithii are provided and features that have helped place these copal inclusions in their new combinations are discussed.

History of tachinid classification (Diptera, Tachinidae).

The history of the classification of the Tachinidae (Diptera) is traced from Meigen to the present. The contributions of Robineau-Desvoidy, Townsend, Villeneuve, Mesnil, Herting, Wood and many others are discussed within a chronological, taxonomic, and geographic context. The gradual development of the Tachinidae into its modern concept as a family of the Oestroidea and the emergence of the classificatory scheme of tribes and subfamilies in use today are reviewed. Certain taxa that have in the past been difficult to place, or continue to be of uncertain affinity, are considered and some are given in a table to show their varied historical treatments. The more significant systematic works published on the Tachinidae in recent decades are enumerated chronologically.

The type specimens of Tachinidae (Diptera) housed in the Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", Buenos Aires.

The type material of species of Tachinidae (Diptera) housed in the collection of the Entomology Division of the Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" were examined and are herein documented. The collection contains 202 type specimens consisting of 54 species described by E.E. Blanchard and 12 described by J. Brèthes. Comparison of their original descriptions with the label information reveals the existence of 24 holotypes, 1 lectotype, 141 syntypes and 36 paratypes. Complete information is given for each type, including reference to the original description, label data, and preservation condition.

Neoethilla, a new genus for the first record of the Ethillini from the New World (Diptera, Tachinidae, Exoristinae).

New genus Neoethillagen. n., is described to include two New World nominal species formerly recognized as valid species in Winthemia Robineau-Desvoidy: Exorista ignobilis van der Wulp and Winthemia antennalis Coquillett. Winthemia antennalis is proposed as a junior synonym of Exorista ignobilissyn. n.Neoethilla ignobiliscomb. n. is removed from the Winthemiini and placed in the tribe Ethillini (Exoristinae) based on a study of the external features of adults, male terminalia, female reproductive system, and egg morphology. The small tribe Ethillini, not hitherto known from the New World, currently comprises fourteen genera worldwide. The phylogeny and systematics of the Ethillini and their relationships with related tribes are discussed and documented by descriptions and illustrations of relevant character states.

TACHINIDAE: evolution, behavior, and ecology.

Tachinidae are one of the most diverse and ecologically important families in the order Diptera. As parasitoids, they are important natural enemies in most terrestrial ecological communities, particularly as natural enemies of larval Lepidoptera. Despite their diversity and ecological impact, relatively little is known about the evolution and ecology of tachinids, and what is known tends to be widely dispersed in specialized reports, journals, or texts. In this review we synthesize information on the evolutionary history, behavior, and ecology of tachinids and discuss promising directions for future research involving tachinids. We provide an overview of the phylogenetic history and geographic diversity of tachinids, examine the evolution of oviposition strategies and host associations, review known mechanisms of host location, and discuss recent studies dealing with the ecological interactions between tachinids and their hosts. In doing so, we highlight ways in which investigation of these parasitoids provides insight into such topics as biogeographic patterns of diversity, the evolution of ecological specialization, the tritrophic context of enemy-herbivore interactions, and the role of host location behavior in shaping host range.
