Stephanus turcomanorum Semenov, 1891: 435 , ♀.

Material examined. Saudi Arabia: 1 ♀, Riyadh, Rawdhat Khoreim [25°25′57″N, 47°13′52″E], 572 m, 14.iv.2012, by sucking on Nitraria retusa , leg. Al Dhafer et al. ( KSMA). GoogleMaps

Diagnosis. FEMALE. Length 12 mm; fore wing: 4.5 mm.; ovipositor length: 9.0 mm. morphometric ratios: Cxl/Cxh 3.5; tw/iEE 0.59; btl/btw 3.3; Pnl/Smw 1.18; Pnl/Ew 1.88; GSl/Ptl 3.2; Ptl/T3l 1.45; Hdl/Ew 2.27; Ew/Tw 1.76; iEE/eEE 0.6; Ppl/Ew 1.59; io/oo 8.3; Ptl/alinotum 1.53; 1Cu/1cu-a 1.11.

Description. Body length 12 mm; fore wing length 4.5 mm; ovipositor length 9.0 mm.

Head ( Figs 25 View FIGURES 23 – 28 ̄28). Globular. Antenna with 22 long and slender flagellomeres. Frons ventrally until middle area between inner eye margins transversely rugose; frontal carina indistinct. Cornal area with few radiating carinae from central tubercles, integument smooth in between; anterior and central coronal tubercles sharp and well-elevated, while posterior coronal tubercles weakly elevated and widely separated; large areolations could be seen in the area between anterior and central coronal tubercles. Vertex anterior to posterior coronal tubercles with a large transverse carina, followed by a shorter one, integument smooth and shiny in between; posterior area of vertex transversely rugose followed by areolated area reaching occipital carina. Gena alutaceus, with some fine transverse striations towards hypostemal carina. Malar area 0.73 × mandibular base. Occipital carina thin and sharp.

Mesosoma ( Figs 29 & 30 View FIGURES 29 – 32 ). Pronotal colo deeply emarginated anteriorly, U-shaped, as deep as broad, with 4 thick annulations; pronotal fold absent. Pronotum transversely rugose medially and areolate laterally, broadly concave posteriorly; pronotal lobe weakly developed, strigate. Mesoscutum areolate, sparsely punctate laterally; notauli absent. Scutellum smooth and shiny medially, with fine longitudinal striations laterally and few punctures posteriorly. Propodeum alutaceus antero-laterally, irregularly areolate medially, that are separated by short distances less than areolar diameter, becoming larger and closer posteriorly. Mesopleuron anteriorly coarsely areolate, followed by finely punctate large area above, with shiny area between punctures and areolate ventrally. Metapleuron coarsely areolate throughout.

Wings. Fore wing ( Fig. 33 View FIGURES 33 – 34 ) with venation beyond 1cu-a and IM are spectral; vein 2 r fully tubular, vein 1Cu tubular at basal 0.75; vein 4Rs upwardly curved, with 4 well-separated setae along its length, terminating a distance from wing apex. Vein M+Cu with three widely separated fine hairs at base; 1cu-a slightly postfurcal, with a slight break at point of connection with 1-1A.Vein 1-1A straight; vein 2-1A entirely spectral. Hind wing with Sc+R vein fully tubular, other veins are indistinct.

Legs ( Figs 31 & 32 View FIGURES 29 – 32 ). Hind coxa transversely strigate, with exterior longitudinal oval alutaceus area. Hind femur finely alutaceus; right hind femur with short triangular tooth at basal 0.2, followed by 2 large ones medially and a tooth at preapical 0.7; 2 small unequal tubercles present between central ones and 3-4 smaller ones present after the apical one and extending to apex ventrally; all tubercle apices bearing single short hair. Left femur, three tubercles between large central teeth, while those after the apical tooth not evident. All teeth smooth and not bearing apical hairs as tubercles. Hind tibia alutaceus along its entire length, with basal half thin, apical half dilated and compressed ventrally; compressed part with two longitudinal carinae, with golden pilosity mesally that becomes longer and denser distally.

Metasoma ( Figs 24 View FIGURES 23 – 28 & 34 View FIGURES 33 – 34 ). Petiole finely transversely strigate, petiolar tubercles absent. Metasoma finely alutaceus on remaining tergite. T3 petiolate, T4 with two sub-basal rounded spots laterally. Pygidium small, posterior margin emarginate. Ovipositor about 0.75 body length.

Color ( Figs 23 View FIGURES 23 – 28 ̄25, 29 & 34). Head and metasoma dark reddish-brown; mesosoma black, posterior rim of pronotum golden; petiole reddish brown at basal 0.2 and distal 0.1; T3 reddish brown basally; T4 with two subbasal rounded yellowish to ivory spots laterally; ovipositor reddish, ovipositor sheath dark brown to black.

Remarks. This species is similar to F. turcomanorum (Semenov) in having pronotum entirely transversely strigate and areolate laterally; the yellowish spots on T4 small and widely separated; vein 1-1A of fore wing straight, vein 2-1A spectral.

However, it differs from it in the following combination of characters (based on Aguiar et al. 2010): Comparative morphometrics:: Cxl/Cxh 3.5 (3.41); tw/iEE 0.59 (0.59); btl/btw 3.3 (1.63); Pnl/Smw 1.18 (1.32); Pnl/Ew 1.88 (2.14); GSl/Ptl 3.2 (1.19); Ptl/T3l 1.45 (2.16); Hdl/Ew 2.27 (2.00); Ew/Tw 1.76 (1.31); iEE/eEE 0.6 (0.53); Ppl/Ew 1.59 (2.05); io/oo 8.3 (8.5); Ptl/alinotum 1.53 (1.57).

Other characters: vertex anteriorly, behind posterior pair of coronal tubercles, with large transverse carina followed by shorter one ( Figs 25 & 26 View FIGURES 23 – 28 ) (in turcomanorum , the large carina is U-shaped); gena entirely alutaceus ( Fig. 27 View FIGURES 23 – 28 ) (in turcomanorum , gena micro-areolate, centrally weakly alutaceus appearing smooth); scutellum smooth medially, finely longitudinally striate laterally, and sparsely punctate posteriorly ( Fig. 29 View FIGURES 29 – 32 ) (in turcomanorum , scutellum alutaceus medially, with sparse shallow foveola, with some longitudinal striations laterally); propodeum alutaceus antero-laterally, irregularly areolate medially (in turcomanorum , coarsely rugose); vein 1Cu spectral at apical 0.25 ( Fig. 33 View FIGURES 33 – 34 ) (0.2 in turcomonarum).

Distribution. Turkmenistan ( Semenov 1891), Tajikistan, Afghanistan ( Tobias 1988), Saudi Arabia (Riyadh region) (new record).
