The genus Eirenis encompasses 20 small-sized colubrid species, showing its highest diversity with 13 species in Iran. Eirenis coronelloides (Jan, 1862) is one of these 13 species which found in western Iran. Two additional specimens of this species were collected in western Ilam Province, Western Iran. This taxon has a crescent-like distribution in the Middle-East with eastern ramous extended in the western and southwestern regions of Iran. Morphological analyses of the additional specimens are presented. The number of ventrals in some specimens increases geographically from west to the east. This taxon is distributed in two different geographic regions, namely the Zagros Mountains and the western foothills of the Zagros Mountains, with different climatic conditions. This species is sympatric with at least three congeners in western Iran, namely E. collaris, E. persicus and E. punctatolineatus.
