Eustenancistrocerus iranicus Gusenleitner in Gusenleitner et al. 2013: 110, figs 6–9, ♂ (type locality: “ Iran, Fars, Larestan, 870m, 27°32’N, 54°22’E ”).
Description of female (hitherto unknown). Body length (from head to apical margin of T2) 7–7.5 mm; forewing length 5–5.5 mm. Head about 1.2× as wide as long in frontal view. Clypeus about 1.4× as wide as long, its apical emargination about 0.25× as deep as wide, taking about 0.4 of clypeal width, apical teeth rounded. Distance between lateral ocellus and occiput about 1.16× as distance between lateral ocelli and about 1.12× as distance between lateral ocellus and compound eye. Occipital carina complete at gena and rounded dorsally. Width of gena in front of ocular sinus about 0.8× as width of compound eye at ocular sinus. Pronotal carina complete; antero-lateral angles of pronotum in dorsal view blunt. Scutum and scutellum slightly convex. Epicnemial carina distinct. Metanotum crenulate dorsally and sharply edged posteriorly. Propodeum without distinct dorsal surface; median suture with carina at lower 3/4–4/5 of propodeal concavity. Propodeal valvula separated from projection of submarginal carina of propodeum, rounded to rectangularly rounded apically. T1 with transverse carina separating anterior vertical part from posterior horizontal part; anterior vertical part of T 1 in frontal view narrowing posteriorly, with medio-apical margin more than three times narrower than maximal width of anterior vertical part of T1; posterior horizontal part of T1 widening posteriorly, about 0.4× as long as apically wide. T 2 in dorsal view about 1.2× as wide as T1 apically; apical margin of T2 depressed. Basal transverse furrow of S2 with longitudinal carinae longer medially than laterally. S2 posterior to basal transverse carina very slightly convex and then nearly flat, without longitudinal furrow.
Clypeus shining, shallowly rugoso-punctate, interspaces exceeding puncture diameter. Lower 2/3 of frons and gena sculptured similarly to clypeus but slightly coarser. Sculpture becoming more distinct on upper 1/3 of frons and vertex where punctured deep, reaching 1/3 of diameter of median ocellus, interspaces less than puncture diameter, less shining. Dorsal surface of pronotum, scutum, and scutellum with coarse punctures reaching 1/2 of diameter of median ocellus, interspaces less than puncture diameter, moderately shining. Lateral surface of pronotum dull, with coarse longitudinal wrinkles. Tegula shining, with indistinct microsculpture only. Dorsal and ventral mesepisternum and mesepimeron punctate even coarsely than dorsal surface of pronotum, scutum, and scutellum, interspaces very narrow and rather dull. Epicnemium, posterior surface of metanotum, and metapleuron with dull reticulate microsculpture. Dorso-lateral surface of propodeum sculptured similarly to dorsal and ventral mesepisternum and mesepimeron. Lateral surface of propodeum with shallow punctures forming longitudinal rows, interspaces edge-like, bottom of punctures dull, with reticulate microsculpture. Propodeal concavity transversally wrinkled, with small indistinct punctures and reticulate microsculpture between wrinkles. Anterior vertical part of T1 shallowly irregularly punctate, interspaces reaching puncture diameter, rather shining but with distinct micropunctation. Posterior horizontal part of T1 coarsely punctate basally, interspaces much less than puncture diameter, with reticulate microsculpture; punctation becoming much finer and sparser towards apical part of T1 where interspaces reaching puncture diameter. T2 with deep dense punctation at central part, punctures somewhat elongate, interspaces reaching puncture diameter, with reticulate microsculpture; punctures becoming larger towards base of T1 and sparser towards apical margin of T1. Following terga with punctures becoming finer and sparser towards apex of metasoma; T6 mostly with reticulate microsculpture, with only few indistinct punctures. S2 posterior to basal transverse carina shallowly punctate, interspaces less than puncture diameter; punctures becoming deeper, finer, and sparser towards apical margin of S1. Following sterna with punctures becoming finer and sparser towards apex of metasoma; S6 mostly with reticulate microsculpture, with only few indistinct punctures.
Setation weakly developed. Mandible and labrum with erect setae as long as diameter of median ocellus. Frons with setae as long as about 2/3 of diameter of median ocellus. Other parts of body with only very short setae, about two times shorter than those on frons or even shorter. All setae whitish.
Basal color black. Following parts yellow: basal spot on mandible, clypeus, scapus, M-shaped spot on lower 2/3 of frons, upper 2/3 to 3/4 of gena, dorsal surface of pronotum, tegula, parategula, scutellum, dorsal mesepisternum, small spot on ventral mesepisternum (absent in one specimen), dorso-lateral surface of propodeum, broad apical band on T1 emarginate medio-basally, lateral spots fused with apical band on T2, apical bands on T3 – T5 extended medially and laterally towards base of these terga, T6, large apical band on S2 taking nearly whole sternum and emarginate medio-basally; apical bands on T3 – T5 extended medially and laterally towards base of these sterna, lateral spots on S6 (absent in one specimen), legs except brownish-yellow tarsi and dark apical ends of claws. Mandible ferruginous except black teeth and basal yellow spot. Labrum brownish-yellow. Antennal sockets and flagellum ventrally ferruginous; dorsal surface of flagellum dark brown. Wings fuscous, particularly in marginal cell; veins and pterostigma dark brown.

Distribution. * Azerbaijan (Nakhchivan AR), Iran.
Remarks. The female of this species is similar to Eustenancistrocerus amadanensis (de Saussure, 1855) but clearly differs from the latter species by a longer clypeus (Fig. 2C). Besides, both sexes of E. iranicus have the transverse carina of T1 very distinct (Fig. 2D) from that of E. amadanensis.
