Figs 1–2 View Figs 1–6 , 14–17 View Figs 7–17 , 83 View Figs 76–91 .

SYNONYMY: Stenotus paykulli (Turton,1802) ; Stenotus sareptanus Jakovlev, 1877 .

SPECIMENS EXAMINED. Iran, Guilan province: Totkabon; Shirkoh 2♂, 2♀ (36°89´N 49°59´E, 303m), 31.V.2018. Mazandaran province:Ramsar 2♂, 2♀ (36°90´N 50°58´E, 580 m), 25.VI.2018, M. Zamani, sweeping .

DIFFERENTIAL DIAGNOSIS. S. binotatus is easily distinguished from S. pallidus Reuter, 1904 and S. brevior Poppius, 1910 by its small size: 5.6– 6♀ (in S. pallidus 6.3– 6.7 ♀), presence of black markings on pronotum (in S. pallidus pronotum uniformly yellow; in S. brevior black markings indistinct), labium reaching metacoxa and often surpassing metacoxa (in S. pallidus short and not extending beyond the mesocoxa), 2 nd antennal segment 3x as long as 1 st antennal segment (4x in S. brevior ), posterior margin of pronotum 2.3–2.5x as long as 1 st antennal segment (3x in S. brevior ) [ Poppius, 1905; Akramovskaya, Kerzhner, 1978].

This species has been reported from all zoogeographic regions. Namyatova et al. [2013] and Kim and Jung [2016] provided detailed redescriptions quite recently. Here we have briefly redescribed the male and female genitalia as follow.

MALE GENITALIA. Left paramere sickle-shaped, sensory lobe strongly swollen and greatly expanded, apophysis prominent and widened, distally angulate, with flattened tip ( Fig. 15 View Figs 7–17 ); right paramere subapically with a depression, apophysis apically inclined upward, apex almost flattened ( Figs 16– 17 View Figs 7–17 ); vesica multilobed, membranous lobes apically spinose, medial lobe apically with concentration of enlarged spines ( Fig. 14 View Figs 7–17 ).

FEMALE GENITALIA. Dorsal labiate plate small; sclerotized rings small, elliptical, widely separated, oval, placed laterally and oriented vertically; posterior wall with interramal sclerites, spinulate interramal lobes (medially separated), dorsal structure and large median process ( Fig. 83 View Figs 76–91 ).

COMMENTS. Stenotus is composed of 53 species in the world ( Schuh, 2002 –2013). Eleven species are known in Palearctic region and only two species were previously recorded from Iran (including S. pallidus and S. brevior ) [ Wagner, 1968; Linnavuori, 2009]. Stenotus binotatus as a new record from Iran, was collected on Geramineous plants.
