Note. Euxoa tritici , E. nigrofusca (Esper, [1788]) and E. eruta (Hübner, [1817]) were previously considered as three distinct species ( Fibiger 1997) but the further morphological and molecular studies did not support this opinion ( Hausmann et al. 2011; Mutanen 2005; Behounek 2011) suggesting that nigrofusca and eruta are most probably only ecological forms of E. tritici . Huemer (2013) considered nigrofusca and eruta as synonyms of E. tritici and this concept is also followed in the present paper.

Literature: Pospelov (1962); Titov et al. (2017b, as E. nigrofusca and E. eruta ).
