During a survey conducted to study mermithids fauna in the rangelands of Jolfa County in East Azarbaijan province of Iran, a population belonging to the genus Oesophagomermis was recovered. The specimen is characterized by its 8.60-11.60 mm long body, six cephalic papillae; no lip papillae; absence of cuticular recess at the frontal end; cuticle with very fine cross fibers; oral opening central and terminal; head rounded and 30-36 μm broad; amphidial fovea pocket-shaped; six hypodermal cords at mid-body; pharynx long, passes through the entire body, almost reaching near the trophosome end; female reproductive system didelphic-amphidelphic; vulva oblique, at 54-57% of body length; vagina S-shaped, 75-135 μm long, twisted in one plane, posterior loop is smaller in length than anterior loop; young female tail conical with the appendage of the previous molt stage; postparasitic juveniles with tail appendage, conoid and long. The newly collected population from Iran was compared with four previously known species of the genus, the Iranian population could mainly be separated based on presence of a long and conoid appendage in tail tip of post-parasitic juvenile. However, due to the lack of adult females and males as well, it was not identified up to the species level and therefore the population is considered as Oesophagomermis sp.
