Nine species were recorded for the first time in Syria. The status of 2 subspecies previously recorded was considered doubtful, and alternatives were suggested. Modern classification of the identified species is given; type species and some synonyms of taxa are also mentioned. A checklist of Cerambycidae fauna of the SCR is suggested.This knowledge of the Cerambycidae in SCR was a result of the study and exam- ination of a total of 1224 specimens collected from 173 sites distributed across the different areas of the SCR during the period from 2011 until 2014. Collected specimens were prepared, examined, and then identified. All specimens were curated and permanently preserved in Entomology Laboratory of Tishreen University. Available chorotypes, distribution ranges of the identified species are provided; relating remarks, personal observations, and, sometimes, suggestions are also supplied.
