A919AB4FFFD3F94BFF09FA7141093FDA.taxon	materials_examined	Type material: Saudi Arabia, Holotype (♀), Fifa Mountain (Jazan Province), 1260 m [17 º 16 ’ 07 ʺN 43 º 07 ’ 32.3 ʺE], May, 2023, Malaise trap in coffee orchard, Usama Abu El-Ghiet collector. Recognition. The new species belongs to B. tridens group because of the following combination of characters (de Beaumont 1954; Schmid-Egger 2004): eyes noticeably convergent towards clypeus; flagellum normal, not claviform, F 1 about 2.2 × as long as wide; clypeus shorter than least distance between eyes; front metatarsus not enlarged; hindfemur more than 3.5 × as long as wide; gastral terga shiny, sparsely punctate. Characters of our female specimen does not agree well with Schmid-Egger’s key (2004: 12). It resembles B. proximus in having T 1 with a band interrupted medially, T 2 with complete band, T 3 with small band medially and T 6 black. It differs from B. proximus in having T 4 completely black (T 4 with complete yellow band in B. proximus), and T 5 with complete band (T 5 with lateral spots in B. proximus). It matches B. bytinskii in de Beaumont’s key (1954: 246, couplet 2) in having the propodeum without posterior notch and T 4 entirely black. However, it differs from female of B. bytinskii in having T 1 with the band interrupted medially (Fig. 1 E) (T 1 with complete band in B. bytinskii, see fig. 60 in Schmid-Egger 2004, or very slightly notched medially (de Beaumont 1954), as well as Saudi Arabian specimens (see Fig. 3 E); T 5 with band widened laterally and medially (T 5 with band widened laterally, and deeply concave medially in B. bytinskii); scutellum, metanotum and propodeum all black (Fig. 2 B) (scutellum with lateral yellow spots, metanotum with central band, and sometimes outer edge of propodeum with some yellow in female of B. bytinskii (Fig. 3 E )); S 2 and S 3 with lateral small triangular yellowish spots (Fig. 3 C) (S 2 – S 5 with lateral spots and small band apically in female of B. bytinskii); apical flagellomere distinctly excavated ventrally, spoon-like (Fig. 3 A) (apical flagellomere normal in female of B. bytinskii); clypeus with baso-medial black, quadrate spot, among which a rounded yellow spot could be seen (Fig. 1 D) (clypeus with apico-median black spot in female of B. bytinskii (Fig. 3 D )).	en	Gadallah, Neveen S., Edmardash, Yusuf A., Abu El-Ghiet, Usama M., Al-Fifi, Zarrag I.

A919AB4FFFD7F946FF09FAC740AE394E.taxon	discussion	Comments. The double-edged gastral terga of the species attributes it to the genus Synnevrus A. Costa, 1859 based on Guichard (1986) and Nemkov (2001). However, in a cladistic analysis of the subfamily Bembecinae by Nemkov & Lelej (2013), based on morphological characters, Synnevrus was synonymized with Nysson Latreille. In a personal communication, W. Pulawski recognizes this synonymy because of some intermediate species. Our female specimen greatly agrees with Schmid-Egger’s holotype male of the United Arab Emirates (2011) in having the thorax mainly black (Fig. 5 A), with a yellow pronotum (Fig. 5 A), scutellar base yellow (Fig. 5 A), reduced yellow markings on the gaster (Fig. 5 B), as well as the reddish ferruginous tegula and T 1 (Fig. 5 A, B); the body sculpture; a sharply angulate antero-lateral side of the pronotum (Fig. 4 A); antenna without any yellow. It differs from the male in having a larger body size (5.5 mm rather than 4.0 mm); S 1, S 2 and S 6 reddish ferruginous, and remaining sterna dark brown (Fig. 5 C) (in the holotype male, the sterna are black with some reddish parts, and S 7 is reddish). It also resembles N. barrei Radoszkowski (Nemkov 2001, as Synnevrus barrei) in having the double-edged gastral terga; the presence of lateral spine on the propodeum (Fig. 5 A); pronotum sharply angulate antero-laterally (Fig. 4 A). However, it differs from N. barrei in having the thorax mainly black (mainly ferruginous in N. barrei); body length 4.5 mm (in N. barrei, 6.0 – 6.5 mm).	en	Gadallah, Neveen S., Edmardash, Yusuf A., Abu El-Ghiet, Usama M., Al-Fifi, Zarrag I.

A919AB4FFFDAF945FF09F91846C93B32.taxon	diagnosis	Diagnosis. The new species belongs to the subgenus Oxycrabro Leclercq, 1961 based on the following combination of characters: occipital carina complete, not interrupted ventrally (Figs 6 B, 7 D); mandible bifid (Fig. 6 C); collar with a small notch medially (Figs 6 B, 7 D); mesopleuron with small denticle in front of midcoxa; pygidial plate slightly depressed on apical half (Fig. 7 B); body small-sized (4.5 – 4.8 mm) (Leclercq 1961, 2009: 158, couplet 1). The subgenus Oxycrabro includes three currently known species (Bohart & Menke 1976; Leclercq 2009; Pulawski 2023): C. (O.) acanthophorus (Kohl) (western and central Palearctic), C. (O.) federationis Leclercq (Malaysia), and C. (O.) taru de Beaumont (Turkey). Our specimens do not agree with any of the three species. They differ from C. taru in having the free margin of the middle clypeal lobe with three distinct minute, rounded teeth (Fig. 6 D) (in C. taru the median lobe of the clypeus is slightly concave, see de Beaumont 1967: 353, fig. 71); F 1 is 2.0 × as long as wide (in C. taru, F 1 is 1.3 × as long as wide); gaster sculpture differs in both species. C. arabicus differs from C. acanthophorus in having the gastral T 2 and T 3 without basal depressions (in C. acanthophorus both terga are conspicuously depressed basally); flagellomeres distinctly longer than wide (in C. acanthophorus flagellomeres are not longer than wide); although the colour varies in C. acanthophorus, but distribution of yellow maculae differs in both species. The new species differs from C. federationis in the following: propodeum smooth and shiny, with broad median transversely ridged sulcus, lateral surface finely wrinkled (Fig. 7 D) (in C. federationis the propodeum is very finely punctate); the free margin of middle clypeal lobe has three distinct minute, rounded teeth (Fig. 6 D) (in C. federationis the middle lobe of the clypeus is truncate, without any trace of teeth); median sulcus attaining the middle ocellus not deep (in C. federationis this sulcus is very deep); scutum densely finely punctate throughout, not foveolate at apex (Fig. 7 D) (in C. federationis, the scutum is foveolate at apex).	en	Gadallah, Neveen S., Edmardash, Yusuf A., Abu El-Ghiet, Usama M., Al-Fifi, Zarrag I.
