New country record for Greece (island of Rhodes) (see map, Fig. 9 ). The record of the species B . ( B .) unicornis (Schrank, 1789) from the island of Rhodes by Schatzmayr (1936) most likely relates to the species B . ( B .) nireus . Note. The distribution in Iraq is based on a single female specimen from Assur tentatively assigned to this species by Krikken (1977) . We have not studied this specimen, so we cannot confirm with certainty what species it belongs to. In addition, this Iraqi locality of the species is very far from its distribution in Turkey (see map, Fig. 9 ). Their distribution in Syria is based on two females (including the holotype ) collected at “Akbes”. This locality, nowadays a small village Maydân Akbis belongs to the territory of Syria ( Aleppo Governorate ) and is situated very close to the border with Turkey (see map, Fig. 9 ). Between 1881–1926 there was the Trappist monastery “Abbaye d’Akbès” ( Le Bras et al. 1979 ). The site is not in modern Turkey , as stated in some papers, see Kryštufek et al . (2001) , Keith (2005) or Arnone & Massa (2010) .
