Material examined. 10 ♀♀,, 8 ♂♂: IRAN, West-Azarbaijan Province , Naqadeh, Solduz Wetland, 37º02′ N, 45º35′ E, 1277 m a.s.l., 21 July 2020, 29 April 2021, M. Razmi leg., ex Calamagrostis epigejos GoogleMaps .

Diagnosis (abstracted from Szelényi 1976). Female ( Fig. 23B): head and mesosoma predominantly black ( Figs 23B, 24A); scape ( Fig. 23D), legs including fore coxa, tegula ( Fig. 23B) and gaster ventrally rufous; meso- and metacoxae testaceous ( Fig. 24A); head transverse (about 2.5× as wide as long), frons and vertex with coarse umbilicate punctures ( Fig. 24G,H); occipital carina distinct, postgenal lamella absent ( Fig. 24I); mesosoma elongate; pronotum shorter than mesoscutum; scutellum and mesoscutum about equal in length; dorsum of mesonotum densely punctured with narrow carinulae; propodeum coarsely rugulose, weakly impressed medially ( Fig. 24C,D); wings hyaline, discal setae dusky ( Fig. 24E); marginal vein slightly widened apically, less than 1.5× as long as stigmal vein ( Fig. 24E,F); gaster about as long as mesosoma with tergites laterally finely alutaceous ( Figs 23B, 24B).

Male ( Fig. 23A): body length 1.8‒2.0 mm; body predominantly black, with antenna, including scape ( Fig. 23C), coxae, femora and tibiae darker than female, only tarsi pale ( Fig. 23A); scape convex on its outer surface for one-third of its length; pedicel significantly rounded; flagellum with five funiculars, all of which are notably convex, with two or more rows of erect setae that are approximately twice the width of the funicular; Fu 1 distinctly longer than the following ones and Fu 2 –Fu 5 subequal in length; clava well defined, composed of three segments, and 3× as long as wide ( Fig. 23C); gaster two-thirds length of mesosoma, with a smooth and polished surface without alutaceous sculpture dorsally or laterally; in lateral view, petiole cylindrical and approximately equal in length to metacoxa ( Fig. 23A).

Remarks. Females of this species are similar to those of Eurytoma flavimana Boheman, 1836 , with the primary distinction being the absence of the postgenal lamella and a shorter marginal vein (slightly broadened distally and measuring less than 1.5× the length of the stigmal vein). A comparison of our specimens with the descriptions published by Szelényi reveals minor discrepancies for females: mesocoxae infuscate ( Fig. 23B), whereas the mesocoxae of the holotype are rufous; metafemora rufous (metafemora slightly blackened medially for holotype); and gaster in our specimens slightly longer than the mesosoma (gaster approximately equal in length to the mesosoma for the holotype). Previously, the male ( Fig. 23A) of this species was unknown; and we provide a brief description and clear images of the male for the first time.

Distribution. IRAN: West Azarbaijan Province ( new record). EXTRALIMITAL: Mongolia ( Type locality) ( Szelényi 1976; UCD Community 2023).
