Abstract: A taxonomic account and an annotated checklist of the Finnish Mymaridae
(Hymenoptera: Chalcidoidea) are given, comprising 85 named species in

Stethynium Enock, 1909, 1 subgenus, Anagrus
(Paranagrus Perkins, 1905), and the following 25 species represent new
records for Finland: Anagrus (Anagrus) avalae Soyka,
1956, A. (Anagrus) bakkendorfi Soyka, 1946,
A. (Anagrus) ensifer Debauche, 1948, A.
(Anagrus) nigriceps (Smits van Burgst, 1914), A.
(Anagrus) obscurus Förster, 1861, A.
(Anagrus) parvus Soyka, 1956, A. (Anagrus)
subfuscus Foerster, 1847, A. (Paranagrus)
optabilis (Perkins, 1905), Anaphes (Anaphes)
stygius Debauche, 1948, Camptoptera magna Soyka, 1946,
Cleruchus megatrichus Novicky, 1965, C. taktochno Triapitsyn,
2014, Cosmocomoidea oxypygus (Foerster, 1856), C. tremulae
(Bakkendorf, 1934), Dicopus minutissimus Enock, 1909, D.
moscovit Triapitsyn, 2015, Gonatocerus aegyptiacus Soyka, 1950,
Lymaenon aureus (Girault, 1911), L. longior (Soyka, 1946),
Polynema flavipes Walker, 1846, P. fuscipes Haliday, 1833,
P. pusilloides Debauche, 1948, P. valkenburgense Soyka, 1931,
P. vitripenne (Foerster, 1847), and Stethynium triclavatum
Enock, 1909. New distributional records and taxonomic notes on some genera and
species are also provided. Caraphractus Walker, 1846, syn. nov. is
synonymized with Eustochus Haliday, 1833 and treated as its subgenus,
E. (Caraphractus), stat. revid., and its type species
Caraphractus cinctus Walker, 1846 is transferred to Eustochus
as Eustochus (Caraphractus) cinctus (Walker, 1846),
comb. nov. Eustochus (Eustochus) koponeni Triapitsyn,
sp. nov. is described from Finland and Germany. Lymaenon gracilentus
(Hellén, 1974), stat. restit. is resurrected as a valid species from the
previous synonymy with Lymaenon aureus and redescribed. The previously
unknown male of Alaptus schmitzi Soyka, 1939 is described.
Polynema depressicollis Hellén, 1974, syn. nov., is synonymized with
Polynema (Doriclytus) vitripenne. Anagrus
(Paranagrus) optabilis is newly recorded from the Canary
Islands and Madeira, and Cleruchus megatrichus is for the first time
reported from France.
