 Type material   
 Male (holotype), Jazan (Damad), 17º08 ʹ 05.1 ʺ N 42º45 ʺ 58.8 ʺ E, 20–25.xii.2020, on Moringa oleifera Lam. (Moringaceae) [Malaise trap], leg. Usama Abu El-Ghiet; Paratype: 1 ♂, same data of holotype (with broken head, glued on a card).   
 Diagnosis   
 Oryttus pulawskii is well characterised by the following characters (Figures 21 (a–c)), 23(a)): body mainly black and yellow, with some ferrugineous and reddish brown areas; T1 not globular apically, slightly broader apically; T2 entirely dull black, superficially punctate with large distances between punctures; F8-10 deeply excavated beneath, excavation extremely large on F8; gastral S1 with median longitudinal carina (Figure 22 (d)); S7 very narrow, parallel-sided, deeply emarginate apically in the form of inverted V (Figure 23 (b)); fore wing subhyaline, with dark brown patches in marginal cell, apex of SMC1, all SMC2 and 2nd discoidal cell (Figure 22 (a)); middle tibia with two spurs (Figure 21 (d)).   
 Description of male holotype   
Body length: 12 mm., fore wing length: 9.0 mm.  
  Colouration (Figures 21 (a–c), 22(a) and 23(a,b)).  Body generally black and yellow, with the following reddish brown to ferruginous: head (dark ferruginous), inner margins of eyes reddish above and yellowish below; clypeus reddish brown (except yellow laterally); pronotum and scape above ferruginous. Yellow are: scape beneath, maxillary and labial palps, scutellum (except at base), postscutellum, apical third of gastral T1, T3 (except at base), posterior two-thirds of T4, almost all T5 and T6, T7 (except brownish at apex), small postero-lateral triangular areas on S4-6. Pedicle dark brown, all flagellum orange to bright red. Legs black except: front femur apico-ventrally, inner surface of front tibia, an inner streak on mid tibia, ventral side of front tarsus yellow, all tarsi dark reddish brown; tegula dark brown. fore wing subhyaline, with dark brown patches in the marginal cell, apex of SMC1, all SMC2 and 2nd discoidal cell, pterostigma and wing veins dark brown.   
  Head (Figure 21 (a,b)).  Posteriorly and face densely finely punctate, sparser on posterior margin of head in dorsal view. Covered with very fine pubescence not concealing integument. Clypeus smooth, with dense fine, silvery pubescence not concealing integument, glabrous at apex, convex medially, with straight apical margin. Inner eye margins slightly convergent towards clypeus. Mandible with one subapical, small tooth. Antenna with scape cylindrical, slightly shorter than F1; F1-6 slender, distinctly longer than wide, last flagellomere long, narrowly rounded at apex; F8-10 deeply excavated beneath, excavation very large on F8.   
  Thorax (Figure 21 (a,c)).  Pronotum swollen medially, posterior margin with 2–3 transverse ridges. Mesoscutum densely coarsely punctate, with irregular, finely rugose interspaces. Scutellum and postscutellum superficially foveolate, ridged between foveoli especially on scutellum. Propodeum with V-shaped enclosure, with middle sulcus, coarsely wrinkled around sulcus, lateral sides around enclosure densely coarsely punctate. Lateral panel of pronotum with few oblique striae; mesopleuron densely areolated throughout, metapleuron coarsely rugose. Mesosternum dull, densely superficially punctate. Middle tibia with two spurs.   
  Gaster (Figures 22 (b–d) and 23(a,b)).  Gastral T1 somewhat widened posteriorly, nearly shiny and smooth yellow band, sparsely punctate above; T2 dull, superficially punctate, with large, finely alutaceous interspaces, remaining terga nearly smooth, impunctate. Gastral S1 with median longitudinal carina; S2, S3, and S6 sparsely punctate, sterna smooth; S7 very narrow, parallel-sided, with deep, inverted V-shaped emargination apically. Male genitalia: Figure 23 (c,d).   
 Distribution   
Known only from Jazan (southwestern Saudi Arabia).  
 Etymology   
The species is named in honour of the sphecid expert W. J. Pulawski, who helped in recognising that the species is an undescribed one.
