The species is recorded from the Orontes river basin, Jordan river basin and coastal plain rivers at Syria, Lebanon and Israel.
The subspecies Unio terminalis delicatus is present on the lower Orontes in Turkey and Syria, and in the coastal plain rivers of Syria, Lebanon and Israel. However its presence on most of the coastal rivers is now unlikely due to habitat degradation and is already extinct in Israel (Milstein et al. 2012). The subspecies Unio terminalis terminalis is present on the Jordan catchment in Jordan and Israel (Kinzelbach 1987).
Another subspopulation reported as Unio terminalis is listed from south Anatolia, but this record has been discounted based on taxonomic uncertainties.
