Figs 18A–E , 19A .

Material examined: 1♀, Kharga Oasis (New Valley) [25°31’34.0”N 30°37’19.9”E], May, 2022, blue pan trap in V. faba intercropped with B. napus ; 1♀, Kharga Oasis (New Valley) [25°31’34.0”N 30°37’19.9”E], May, 2022, white pan trap in V. faba intercropped with B. napus .

Diagnosis. Body (including antenna) black, mandible yellow (except dark base and tip), palpi pale yellow; tegula yellow, legs ferruginous (especially femora and tibiae), hind tibia ferruginous, with small ivory area at base and minute black portion apically; hind femur entirely ferruginous, hind trochanter black, with ferruginous apex; hind trochantellus ferruginous; ovipositor ferruginous, ovipositor sheath black. Antenna with 36 antennomeres; mesopleuron smooth and shiny above (epimeron), clearly differentiated from rest of mesopleuron; hind tarsal claw with two teeth along basal half; fore wing with rhomboid areolet, distinctly petiolate; vein 2m-cu with one bulla; propodeum with superomedial and petiolar areas confluent, forming a deep trough distinctly carinated, transversely coarsely ridged along the inner trough; ovipositor about 2.2× as long as hind femur, upwardly curved along whole length, with a preapical notch on upper valve, lower valve distinctly deepened before level of upper notch; ovipositor sheath clavate towards apex, flexible, densely setose along its whole length.

Distribution in the MENA: Egypt (new record)

Comments: This is apparently the first record of S. tibialis for the Middle Eastern and North African countries, and only the second record for the Palaearctic region (from Egypt), after being described from two females from Sweden by Sanborne (1984). Characters of this species agree well with Sanborn’s key of Palaearctic species (1984: 65, couplet 23), as well as his species description (1984: 279), except for the antenna with 35 antennomeres in the Swedish females (36 antennomeres in the Egyptian specimens). Nothing is known about the biology or hosts of this species.
