(2011) with some corrections and additions to the original description (Kaprus & Tsalan 2009). Arrhopalites acanthophthalmus Gisin, 1958 (Figs 3-5) is known from Romania, Austria, France and Spain, while its presence in Germany is doubtful (Bretfeld 1999, Betsch & Fjellberg 2011). Like the latter species, A. acanthophthalmus was also found in the oak-ash-elm forest as well as in the tall herb fen meadow habitat.
