This species was erroneously interpreted by Kaszab (1968) who listed it for Tunceli , by Ferrer & Soldati (1999) who recorded E. corrugatus for Istanbul , Antalya and Bingöl provinces, and by Tezcan et al. (2004) who listed it from Bartın , Muğla and Mersin provinces. In fact, it occurs only from Kahramanmaraş Province in the north to Amanos Dağları ( Osmaniye , Gaziantep , and Hatay provinces) in the south and probably in adjacent areas of Syria . The species was collected from 19:30 to 20: 30 in the old Pinus brutia liana floodplain forest from pine trunks. After 20:30 the beetles climbed higher up the trunks and we could not register their further activity.
