With this study, Cataldag province extending at the provincial borders of Balıkesir and Bursa, the field studies were performed at 11 different study areas per three weeks using pitfall traps and window traps with old and hollow seven different original forest tree species (Alnus glutinosa, Carpinus betulus, Platanus orientalis, Fagus orientalis, Quercus petreae, Q. cerris, Q. cerris x Q. infectoria) in between April and November months during 2014-2015. At the result of the study, 112 saproxylic beetles species belonging to 83 genus of 25 families were identified. Anobium hederae Ihssen, Gastrallus corsicus Schilsky, Hemicoelus canaliculatus (Thomson), Cryptophagus pubescens Sturm, Symbiotes gibberosus (Lucas), Triplax russica (Linnaeus), T. scutellaris Charpentier, Hylis cariniceps (Reitter), Isorhipis marmottani (Bonvouloir), Phloiotrya tenuis (Hampe), Litargus balteatus (LeConte), Sacodes flavicollis (Kiesenwetter), Tetratoma desmarestii Latreille and Synchita undata Guérin-Méneville are the new records for Turkish beetles fauna. 89 saproxylic beetles of 22 families are recorded for Balıkesir and Bursa provinces for the first time. 35 species in red list prepared for endangered saproxylic beetle species in Europe and Mediterrenean basin were determined. Podeonius acuticornis endangered (EN), Cardiophorus gramineus, Megapenthes lugens, Mycetochara quadrimaculata near threatened (NT), Ischnodes sanguinicollis and Lucanus ibericus vulnerable (VU) categories are included. 88 saproxylic beetle species were determined in Susurluk and the most species were collected from P. orientalis (32 species), nonetheless 56 saproxylic beetle species were determined in Mustafakemalpaşa and the most species were collected from Q. cerris (20 species). Saproxylic beetle species were collected with 82 % window trap and 25 % pitfall trap.
