Ephippiochthonius boldorii Beier, 1934

Remarks: The species is known from the neighbouring Austria (Mahnert 2004), Croatia (Ozimec 2004) and Slovakia (Christophoryová & Krumpál 2005; Christophoryová 2013). In Slovakia, it was reported from oak-hornbeam forests in the South-Western part of the country Christophoryová (2013) and similar habitats also exist in the neighbouring regions of Hungary. Therefore, the occurrence of this species is expected from the western half of Hungary.
