Eurytoma leviuscula Szelenyi, 1976

Figs 23 , 24

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 .

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).

Biological association. Currently, there are no documented associations for this species.
