A checklist of the family Simuliidae (Diptera) is provided for Finland and recognizes 56 species. One new record has been added (Simulium latipes) and one name sunken in synonymy (Simulium carpathicum). Furthermore, Simulium tsheburovae is treated as a doubtful record.

Checklist, Finland, Diptera , Simuliidae

Simuliidae is a relatively small family of nematoceran flies, comprised of 2,163 species (2,151 living and 12 fossil) world-wide (Adler and Crosskey 2014). Numerous taxonomical confusions and different views on nomenclature between eastern and western scientists have created confusion in blackfly studies for many decades. Some taxonomical issues concerning species occurring in North Europe have been resolved by recent synonymisations (Raastad et al. 2010, Adler and Crosskey 2014). Systematics and nomenclature of the enumeration follow that of Adler and Crosskey (2014), and only the most relevant synonyms used in previous checklists for Finland are listed.

The faunistic level of knowledge in Finland is good, only few changes were made since compilation of the previous checklist (Ilmonen and Adler 2008). Few additional species can be expected to be found, and many taxonomical issues have been resolved within the last two decades.

Number of species:

World: 2151 species (Adler and Crosskey 2014)

Europe: 230 species (Adler and Crosskey 2014)

Finland: 56 species

Faunistic knowledge level in Finland: good

= pygmaeum of some authors

Simulium tsheburovae (Rubtsov, 1956) see Notes

Simulium fuscipes (Fries, 1824). Adler and Crosskey (2014) treat fuscipes as a valid species of S. ruficorne species group in the subgenus Nevermannia, but no known records exist from Finland.

Simulium meigeni Rubzov & Carlsson, 1965. Adler and Crosskey (2014) recognize the identity of S. meigeni within the subgenus Hellichiella, but there are no known records of this species in Finland. The name pygmaeum in Kuusela (1971) refers to the form of pygmaeum that is a synonym for pusillum, not meigeni (see Adler and Crosskey 2014).

Simulium tsheburovae (Rubtsov, 1956). No confirmed records of this species exist from Finland (Raastad et al. 2010), and the name probably subsumes one or more of the existing species within the subgenus Hellichiella (Adler and Crosskey 2014).
