Abstract

Nearly thirty-five years have passed since Hackman published his “Check list of the Finnish Diptera” (1980). The number of true flies (Diptera) known from Finland has increased by more than two thousand species since then. At the same time, hundreds of erroneous records have been recognized and purged from the checklist.

ZooKeys issue 441 provides a new checklist of the Diptera species of the Republic of Finland. This introductory paper presents the rationale behind the project, provides technical documentation on the checklist format and sources used, and summarizes the results. The remaining papers in this issue cover one or more Diptera families in detail.

Two electronic appendices are provided: supporting data (additional references to first published records and the previous checklist) and a complete list of Finnish Diptera taxa in Darwin Core compliant format for easy computer access and processing.

The new checklist records 6920 fly species from Finland, 2932 belonging to the nematoceran or lower flies and 3989 to the suborder Brachycera. The changes since 1980 are most prominent in the Lower Diptera. For example, more than 400 non-biting midges (Chironomidae) have been added since 1980, and the number of moth flies (Psychodidae) known from Finland has more than tripled. Among the larger families, large increases in known Finnish species are also seen in Cecidomyiidae (161% increase), Pipunculidae (98%), and Chironomidae (90%).

Introduction

The Diptera is a large order of holometabolous insects commonly known as flies and midges. With some 150,000 described extant species (Pape et al. 2011) and many more still undescribed, the Diptera is one of the most successful groups of animals by any measure. Flies and midges are also an important part of food webs in most land and freshwater ecosystems, particularly so in the arctic and alpine zones (Mani 1968, Pape 2009a). The economic relevance of flies is also considerable (see Pape 2009b for a recent summary): they are key pollinators and biological control agents, but also – less beneficially – important vectors of human and domestic animal diseases.

Why a new checklist

The history of Finnish Diptera catalogs starts with Evert J. Bonsdorff (1861, 1866), who reviewed a part of the brachyceran fauna known from the country at the time, totaling 657 species. Systematic maintenance and publishing of faunistic data began with the start of Wolter Hellén’s amazing series of summary papers covering new country records (and deletions) of all Insecta and running uninterrupted for six decades (Hellén 1922, 1926, 1931, 1936, 1941, 1946, 1952, 1956, 1961, 1966, 1971, 1976). Richard Frey, Lauri Tiensuu, and Ragnar Storå (1941) published the first complete list of Diptera recorded from Finland. It included 3824 species.

The era of Hellén culminated in a revised list of Finnish Diptera by Walter Hackman (1980a, 1980b, 1980c) in cooperation with Bernhard Lindeberg and Rauno Väisänen. The number of species had increased to 4852. Hans Silfverberg succeeded Hellén as the author of regular updates on additions and deletions to the Finnish insect fauna (Silfverberg 1981, 1986, 1991, 1996, 2007, 2012).

Nearly thirty-five years have passed since Hackman’s checklist. The number of Diptera species known from Finland has increased by more than two thousand species since 1980 (an increase of more than 40%). Several hundred erroneous records have been recognized during the same period. Many new names have been introduced and others found invalid, incorrectly used, or synonymized. The Diptera fauna of the whole Palaearctic Region has been catalogued (Soós and Papp 1984–1993) and many new local, regional, or global checklists have been published.

At this point, an updated checklist is urgently needed to provide a current reference to the Diptera fauna of Finland as a fresh starting point for further studies into the taxonomy, ecology, and other aspects of flies in Northern Europe.

Methods and format

Definition of a checklist

There is no universally accepted definition for an entomological checklist. The word is often used for lists of species with more information than merely valid names, but without comprehensive details on nomenclature or distribution and incomplete literature references. This new checklist of Finnish Diptera falls into category 5 on the comprehensiveness scale of Thompson and Knutson (1987). It does include full names with authorships and some but not all synonyms. Some literature references are provided in an Suppl. material 2.

National insect checklists have traditionally included the species recorded at least once from the country. Exotic imports without locally reproducing populations are usually excluded, but vagrants are included. This is by no means the only possible approach: the latest Danish list (Petersen and Meier 2001) use a predictive approach: it lists not only the species actually recorded from the country, but also those that are likely to be present based on the fauna of neighboring countries. The latter method works best when the fauna of the surrounding areas is at least as well known as the study area.

Taxonomic, geographical, and temporal limits

This checklist covers the Diptera fauna of the Republic of Finland. Only species recorded at least once within the current (i.e. post-1944) borders are included.

Many species were originally reported from Finland on the basis of specimens collected from areas ceded to Russia in 1944. If no reliable records (preferably voucher specimens) from within the current borders of the country exist, species were excluded from the checklist. In some cases – e.g. the muscid Coenosia comita (Huckett, 1936) – it has been impossible to determine whether the purported Finnish collecting localities fall within the current borders of the country. These species are indicated with a question mark on the checklist and are usually accompanied by a comment in the Notes section of the relevant paper.

No fossil or subfossil records were considered during the preparation of the checklist. Nationally extinct species are included. In practice, the oldest collected Diptera specimens from Finland are from the early 19th century, so all of the species in this checklist have been found in the country at least once during the last two hundred years.

Data sources and validation

Draft checklists for each family were created in the latter part of 2012 by combining data from the most recent checklist of the Finnish fauna of the family in question, the Palaearctic Catalog (Soós and Papp 1984–1993), Fauna Europaea (Beuk and Pape 2012), Silfverberg’s updates to Hackman’s checklist and references therein, other relevant scientific literature, and the Finnish Insect Record Database (Finnish Museum of Natural History 2013). From here onwards, the individual authors of each checklist paper were responsible for data validation.

For a great majority of families, the next step was examining the major Diptera collections in Finland (see the Acknowledgments). Fortunately, these collections have voucher specimens for most Diptera species reported from the country. If no recently identified specimens from the country could be found, the reliability of the record was judged by section authors based on details provided in the literature. For example, the record of Alliopsis longiceps (Ringdahl, 1935) from Finland was rejected. While Ringdahl correctly recorded this species from Finland in 1935, the type location (“Kuusamo bei Paanajärvi”) is now Russian territory, and no later observations have been published.

Exceptions to the procedure include Trichoceridae, Ceratopogonidae, Cecidomyiidae (subfamily Cecidomyiinae), and Phoridae (genus Megaselia Rondani, 1856), for which the checklists are largely based on a critical literature review. For more details on sources and validation, see the introductions and notes of individual checklist papers.

Checklist structure and presentation

The new checklist of the Diptera of Finland is presented in three formats: a series of papers each covering one or more families, a comma separated values (CSV) file with the full taxon list, and a PDF (portable document format) file with literature references for species records. The latter two are included as electronic appendices to this paper.

All checklist papers follow the same general format. An introduction to the families covered is followed by a table or list of number of species recorded from the world, Europe, and Finland. An estimate of the faunistic level of knowledge is also given on a simple three-step scale (poor–average–good). This estimate is admittedly very subjective, being based on individual authors’ judgment. The following factors were considered: the number of species known from Finland in comparison with neighboring countries, taking into account known habitat preferences, etc., of absent species; the number of specialists who have worked with Finnish fauna; the number of publications on the Finnish fauna; and the quantity and quality of identified material collected from Finland.

The Checklist section of each paper starts with the systematic position of the family or families treated. As an example, the checklist of lauxanoid flies starts with:

suborder Brachycera Macquart, 1834

clade Eremoneura Lameere, 1906

clade Cyclorrhapha Brauer, 1863

infraorder Schizophora Becher, 1882

clade Muscaria Enderlein, 1936

parvorder Acalyptratae Macquart, 1835

superfamily Lauxanoidea Macquart, 1835

The family-level classification used follows mostly Marshall (2012), with exceptions noted in the Introductions of individual papers. The presentation order of subfamilies, tribes, genera, and subgenera can be either alphabetical or systematic depending on the author’s preference. Species are always listed alphabetically within a genus or subgenus.

Each species record starts with the name of the taxon, the author’s name, and the year of description. Doubtful records are indicated with a question mark (?) before the species name. The valid name may be followed by one or more additional names used for the same taxon. These names can be younger synonyms, preoccupied names, misidentifications, or common misuses in Finnish or international literature. As an example, the following entry lists three additional names used for Rhamphomyia trilineata.

Rhamphomyia trilineata Zetterstedt, 1859

= sulcatina Collin, 1926

= tibialis auct. nec Meigen, 1822

= propinqua misid.

R. sulcatina Collin is a younger synonym of R. trilineata. The name R. tibialis Meigen was erroneously used for this species by Frey (1956) and others; the genuine R. tibialis of Meigen has not been found in the Nordic countries. Frey et al. (1941) misidentified this species as R. propinqua de Meijere (in reality a junior synonym name for R. sulcata Meigen).

Table 1 lists abbreviations used in the checklist papers.

The Diptera has traditionally been split into two suborders, Nematocera and Brachycera. It is now generally agreed that while Brachycera is a monophyletic lineage, Nematocera is not (see Yeates et al. 2007 and references therein). The Brachycera may have evolved from a bibionomorphan ancestor, but this has so far proved difficult to confirm (Lambkin et al. 2013). The systematic order of Table 2 follows Marshall (2012), with one exception: Conopoidea is given superfamily status. Families are listed alphabetically within each superfamily.

Two nematocerous families dominate by absolute numbers of species: the non-biting midges (Chironomidae) with 780 species, and the true fungus gnats (Mycetophilidae, 691 spp.). These two families also show the largest number of new species reported since 1980 (369 and 260 species respectively). Hoverflies (Syrphidae, 362 spp.) is the largest brachyceran family, followed closely by tachinid parasitic flies (Tachinidae, 319 spp.). The largest absolute increases are seen in Tachinidae (118 spp.) and Anthomyiidae (112 spp.). The relative number of moth fly (Psychodidae) species has more than tripled since Hackman’s checklist, mostly due to the work of Jukka Salmela. Among the larger families, major increases are also seen in the Pipunculidae (98% increase), Cecidomyiidae (161%), and Chironomidae (90%).

Most Diptera families show a decreasing trend in the number of species with latitude in Europe, but some are genuinely more diverse in the boreal zone (see Kjærandsen et al. 2007). The number of species known from Finland compares favorably with the results from neighboring countries (see Table 3). With 6920 species, Finland has the highest reported Diptera diversity among the Nordic countries. Only Germany (9544 species, Schumann 2009) and the Czech Republic (7917 spp., Jedlička et al. 2009) of all the North and Central European countries report significantly higher national Diptera faunas. This must, however, be at least partially attributed to differences between surveying intensity and the history of various countries. Most countries have only a few (if any) active dipterologists. Up until the last decade, access to the taxonomic literature required for Diptera identification was restricted to those working in close cooperation with major taxonomic institutes.

The number of species present in an area does usually increase with the size of the area (see Ulrich and Buszko 2003 for an example involving European insects). Peterson and Meier (2001) presented a species-area curve (of type IV, see Scheiner 2003) for Diptera species of European countries. Figure 1, based on Table 3, is an updated version of their figure. Two simple models (linear and logarithmic) were fitted to the data using least squares fits. One should, however, not draw too many conclusions from these models: the true number of Diptera species present in each country is likely to be significantly larger than the known number of species. Furthermore, large – or at least populous countries—countries are more likely to harbor dipterists, who contribute faunistic records (see Figure 2).

Figure 1. 

The species-area curve for some Northern, Western and Central European countries based on Table 3, excluding the Baltic states (see also Fig. 1 in Petersen and Meier 2001). Data for Finland is marked by a circle, other countries by rectangles. The two lines show linear and logarithmic least-squares fit models for the data.

From an accumulation curve of new records over the last century (Figure 3), one can immediately see that the Finnish fauna is far from completely known. If almost all species present in the country had already been found, one would expect the rate of new records to diminish (but not fall to zero as genuine expansive species would still occasionally arrive). What has actually happened is the opposite; the rate of new discoveries has increased in the last decade. The number of species found as new to Finland during each five-year period seems to reflect the number of active dipterologists in the country. To a degree, this may represent a backlog from the 1980s and 1990s, when the number of dipterists collecting in Finland and publishing new faunistic records was smaller than during the previous 70 years, or in the 21st century. Still, one could predict that the true number of Diptera species present in Finland may be well over eight thousand species, including hundreds of still unknown and undescribed species (Fontaine et al. 2012).

Acknowledgments

Where to begin? Creating this checklist has very much been a collaborative effort, with many amateur and professional dipterists providing insightful commentary and snippets of data since this project began in the year 2002.

First and foremost, I want to thank all authors of the papers in this issue of ZooKeys, and Jukka Salmela, the coeditor of this checklist, for taking responsibility for the papers dealing with the lower flies. This project would not have been possible without the existence of Finnish entomological museums and their sympathetic staff: the Finnish Museum of Natural History (MZH), the Zoological Museums of the University of Turku, University of Oulu, and University of East Finland, the Kuopio Natural History Museum, the Forssa Nature Museum, and the Tampere Museum of Natural History (Vapriikki). Equally critical was the support of Finnish amateur entomologists with significant private Diptera collection, including Jari Flinck (Helsinki), Antti Haarto (Turku), Jari Ilmonen (Karkkila), Jevgeni Jakovlev (Helsinki), Jere Kahanpää (Helsinki), Iiro Kakko (Hämeenlinna), Sakari Kerppola (Helsinki), Lauri Paasivirta (Salo), Jouni Penttinen (Jyväskylä), Jukka Salmela (Rovaniemi), and Kaj Winqvist (Turku). In addition, Miroslav Barták, Hans Bartch, Christer Bergström, Peter Chandler, Milan Chvála, Henry Disney, Neal Evenhuis, Steve Gaimari, Jean-Paul Haenni, Christian Kehlmaier, Valery Korneyev, Iain McGowan, Bernhard Merz, Verner Michelsen, Lorenzo Munari, Alexei Polevoi, Marc Pollet, Adrian Pont, Jindřich Roháček, Michael von Tschirnhaus, Andrzej Woźnica, and Theo Zeegers, among others, contributed by examining collection specimens, providing literature, commenting on preliminary lists or species, and being supportive and friendly when pestered for answers.

The Finnish Expert Group for Diptera (http://dipteratyoryhma.myspecies.info/) provided funds and other support, allowing the author and Kaj Winqvist to spend a few months examining Finnish Diptera fulltime in 2003–2007. Finally, I would personally like to thank my friends K. Winqvist and A. Haarto for introducing me to the fascinating and curious world of flies.
