New species record for Finland . Anagrus ( Anagrus ) subfuscus Foerster, 1847 Anagrus ( Anagrus ) subfuscus Fඈൾ*©ඌඍൾ*© (1847: 214–215). Type locality (of the neotype designated by C*üංൺඉඉංඇං 1989: 109): Belgium , Flemish Brabant, Leuven, Egenhoven. Nൾඈඍඒඉൾ: ♀ [ISNB], examined (T*©ංൺඉංඍඌඒඇ 1998). ?

Ta : Janakkala, Kalpalinna (6757:8369), 7.vii.2017 , V. Vikberg ( 1 ♀ , VVCT ). Remarks. Some female specimens from Finland , more or less attributable to A. subfuscus , as defined by C*üංൺඉඉංඇං (1989) and T*©ංൺඉංඍඌඒඇ (2015b), have an mps on F3 of at least one of the antennae and the ovipositor length: protibia length ratio of 3.5–4.0, thus being intermediate between A. subfuscus and A. ensifer . That may be indicative to their potential conspecificity which, however, will need to be further demonstrated by a combination of detailed morphometric and molecular studies that are beyond the scope of this communication.According to T*©ංൺඉංඍඌඒඇ (2015b), females of the former have one mps on F3 and the ovipositor length: protibia length ratio of 3.0–3.4 whereas those of the latter nominal species lack an mps on F3 and have the ovipositor length: protibia length ratio of 3.9–4.0. However, presence or absence of mps on F3 of the female antenna may vary in several other species of Anagrus (T*©ංൺඉංඍඌඒඇ 2015b), such as A. incarnatus Haliday, 1833 (T*©ංൺඉංඍඌඒඇet al. 2018). Distribution. Palaearctic ( Belgium , Bulgaria , Denmark , France , Germany , Greece , Italy , Japan , Poland , Romania , Russia , Spain , Switzerland , United Kingdom ), Nearctic ( Canada , USA ), and Neotropical ( Argentina ) regions (T*©ංൺඉංඍඌඒඇ 2015b).
