Genus Trypoxylon Latreille, 1796 Trypoxylon Latreille, 1796: 121, no included species. Type species: Sphex figulus Linnaeus, 1758, designated by Latreille, 1802.

Gastrosericus moricei E. Sauders, 1910 Fig. 6A–F Gastrosericus moricei E. Saunders, 1910: 529, ♁. Diagnosis. Body length: 7.5 mm. Body colour: see Fig. 6 (A–F). The female of this species shares with that of Gastrosericus sanctus the entire pygidial plate covered with dense, stout setae (Fig. 6F); appressed genal (Fig. 6C) and propodeal pubescence (Fig. 6D); the apical tarsomeres with one or more basoventral spines (spines lacking in some sanctus); gastral terga without yellow bands (Fig. 6A). It differs from G. sanctus by the following: free margin of clypeal lobe arcuate (Fig. 6B) (somewhat sinuate in most G. sanctus, see Pulawski 1995: 119, fig. 102a, b); the lobe free margin and the lip are simple (free margin slightly projecting close to lateral corners in G. sanctus, see Pulawski 1995: 120, fig. 103a, b); apical tarsomeres with one to four basomedian spines ventrally (0–2 spines in G. sanctus). Material examined: 1♀, Farasan, Abdulmajeed farm [16 Q 42.07970’N; 42 Q 08.5781’E], 23–30.ix.2022. Previous Saudi Arabian records: Asir (Wadi Lasaba), Bahra, Riyadh (Pulawski 1995), Jeddah, Haddat Asham (Pulawski 1995; Gadallah & Assery 2004), Hutet Beni Tamim (10 km south of Riyadh) (Gadallah et al. 2013). Distribution: Algeria, Burkina Faso, Egypt, Gambia, India, Israel, Kazakhstan, Libya, Mali, Mauritania, Morocco, Niger, Oman, Pakistan, Saudi Arabia, Senegal, Somalia, Sri Lanka, Sudan, Thailand, Tajikistan, Togo, Tunisia, United Arab Emirates, Uzbekistan, Yemen. Comments. Characters of the only specimen collected agree with Pulawski’s key (1995: 19, couplet 18). It differs from the Arabian specimens in having femora black, pale yellow apically (in the Arabian specimens, femora reddish, pale yellowish apically, Pulawski 1995), but it resembles the Somalian females in having all femora black, yellow at tip (Pulawski 1995). This may be attributed to the fact that Farasan Archipelago belongs to the Afrotropical region.

Nysson arabicus Gadallah & Edmardash sp. nov. Figs 3A–D, 4A, B, 5A–C Type material: SAUDI ARABIA. Holotype (♁), Sala Mountain, 1186 m [17°04’10.5”N 43°07’43.3”E] (Abdul Rahman Al Jabri farm), 15.xi.2022, Malaise trap, on Coffea arabica, collector Usama Abu El-Ghiet. Description of male holotype: body length: 6.0 mm. Colouration (Figs 3A–C, 5A–C): Head and thorax black (except posterior margin of pronotum, tegula, and basal area of scutellum dark ferruginous), antenna with scape (except yellow ventrally), pedicel and the following 4–5 flagellomeres dark reddish brown, rest dark brown; mandible ferruginous with dark tip; abdomen: T 1 mostly dark ferruginous, with two yellow postero-lateral oval markings, posterior margin black; T 2 with thin, medially interrupted yellow band posteriorly; T 3 with broad band posteriorly, narrowly interrupted medially; T 4 and T 5 with complete broad yellow bands posteriorly, T 6 and T 7 entirely reddish; metasomal sterna mostly ferruginous, but S 1 mostly black, ferruginous at base; legs all ferruginous, with some yellow at tip of fore femur, and along whole length of hind tibia dorsally, hind tibia reddish ventrally, with black spurs. Fore wing slightly darkened, fumigated at apex, with dark brown veins. Head (Figs 3C, D, 4A). In dorsal view as broad as mesoscutum, densely rugulose-lacunose, with dense fine silvery pubescence laterally; vertex thin and sharp; frons densely foveolate, with sharp carina between antennal bases, with coarser silvery setae; clypeus with dense silvery setae, with about 4–5 rounded teeth at apex; antennae placed at an elevated tubercle, scape longer than wide, distinctly notched apically, pedicle cup-shape, all flagellomeres transverse, wider than long, last flagellomere longer than wide, 1.5× as long as its basal width, obliquely truncate at apex. Thorax (Figs 3A, B, 4B). Pronotum distinctly angulate antero-laterally, posterior margin coarsely punctate along ferruginous area; mesoscutum densely areolate, scutellum and metanotum densely areolate (except scutellum basally nearly smooth and shiny); scutellum with two indistinct teeth laterally, hardly seen because of the coarse foveolation of the integument; propodeum broadly strigate dorsally, with two pale sharp teeth postero-laterally; tegula with dense fine and shallow punctures; mesopleuron densely foveate, metapleuron transversely strigate, shiny; mesosternum densely foveolate. Legs normal, simple. Wings as in other Nysson species. Gaster (Figs 3A, B, 5B, C). Terga double-edged, T 1 irregularly punctate, with distinct spaces between punctures, punctures coarser and larger in the yellow areas; T 2 and T 3 with dense shallow punctures, alutaceous in between punctures; T 3 slightly elevated and smooth at base, together with the following two terga with punctures more distinct along yellow bands; terga narrowed towards apex; T 6 and T 7 densely foveolate along their whole areas, T 7 with two short spine-like processes, with rounded area in between; S 1 densely punctate with large spaces between punctures, sparsely setose; S 2 with large rounded hump (not tubercle) near to the middle, posterior margins of S 2–4 with fine punctures arranged in two or three rows; S 5 with dense coarse punctures throughout. Female: Unknown. Etymology. This species is named after the Arabian area where the specimen was collected. Distribution: Saudi Arabia (Alridah, Jazan). Comments. On the generic level, the double-edged gastral terga of the new species agree with Synnevrus A. Costa, 1859 (Guichard 1986; Nemkov 2001), however, in a cladistic analysis of the subfamily Bembicinae (based on morphological characters) carried out by Nemkov & Lelej (2013), this genus was synonymized with Nysson Latreille.Another opinion was that of W. Pulawski (pers. comm.), who attributed this to the presence of intermediate cases in some species. The genus is a new record to the Saudi Arabian fauna. The new species agrees with N. barrei (= Synnevrus barrei) in Nemkov’s key (2001: 4, couplet 4) in having two lateral small teeth on scutellum; pronotum sharply angulate antero-laterally (Fig. 4A, B); however, it differs from N. barrei in having thorax mainly black, with few areas ferruginous (Figs 3A, 4B) (thorax mainly ferruginous in N. barrei). Based on Radoszkowski (1893: 71), our male specimen differs from the male N. barrei in having posterior margin of prothorax dark ferruginous, not interrupted medially (Fig. 4A) (with ivory white band, interrupted medially in N. barrei); mesoscutum, scutellum (except ferruginous at base) entirely black (Fig. 4B) (reddish in N. barrei); T 1 with two postero-lateral oval yellow spots, posterior margins of T 2–5 with yellow bands, interrupted medially on T 2 (Figs 3A, 5C) (posterior margins of T 1–4 with ivory-white bands, interrupted medially in N. barrei); gaster ventrally mostly dark ferruginous, except basal two thirds of S 1 black (Fig. 5B) (S 2 reddish in N. barrei); fore wing slightly darkened, fumigated at apex (Fig. 5A) (transparent in N. barrei); only hind tibia along its whole dorsal side (all tibiae ivory white dorsally in N. barrei). On the other hand, the male N. arabicus somewhat agrees with the male N. ohli (Schmid-Egger 2011: 592) in having the sharply angulate antero-lateral sides of pronotum (Fig. 4A); the same body sculpturing (Fig. 3A); the presence of a median bulge between spines at apex of T 7 (Fig. 5C). However, it differs from N. ohli in the following combination of characters: body length 6.0 mm (4.0 mm in N. ohli); antenna with scape yellow ventrally (Fig. 3C) (whole antenna reddish, darkened apically in N. ohli); pronotum dark ferruginous posteriorly reaching dark ferruginous pronotal lobes (Fig. 4A) (light yellow in N. ohli reaching the dark reddish pronotal lobe); scutellum dark ferruginous at base (Fig. 4B) (clear yellow in N. ohli); T 2–5 with yellow bands posteriorly that is interrupted medially on T 2 (Figs 3A, 5C) (T 2 & T 3 with narrower lateral yellow spots, rest of terga black in N. ohli); sternal colour differs in the two species; terga medially without medial bulges (with small medial bulges in N. ohli); S 2 with a distinct, large rounded hump near to middle (absent in N. ohli); hind tibia broadly yellow dorsally (Fig. 3A) (all tibia with narrow light yellow over whole length dorsally in N. ohli). T 6 & T 7 entirely reddish (Fig. 5C) (T 6 partly and T 7 reddish in N. ohli).

It greatly resembles the male of M. papyrus de Andrade, but differs from it in the following: clypeus slightly arcuate (Fig. 8C) (clypeus mesally pointed at apex in M. papyrus, Pulawski 1964: 124, fig. 62); propodeal dorsum densely granulate (striate in M. papyrus; Pulawski 1964); gaster entirely red (T 4 and T 5 clearly brownish in M. papyrus; Pulawski 1964); S 8 with two long spines curved along almost their whole length, parallel-sided at apex (Fig. 10C) (spines parallel-sided throughout in M. papyrus, see Pulawski 1964: 123, fig. 63); gonoforceps with dense long setae that are distinctly bent medially (Fig. 10D) (bent at apex in M. papyrus; see Pulawski 1964: 123, fig. 64). It also resembles M. ctenopus Kohl in having posterior ocelli closer to each other than the distance between each of them and the posterior ocellus (Fig. 8B); radial cell distinctly larger than the petiolate SMC 2 (Fig. 10E). However, it differs from M. ctenopus in the following (based on Kohl’s key to males, 1885: 221, couplet 2): mesoscutum dorsally with noticeable side corners in M. ctenopus (side corners gently rounded in M. sauditus, Fig. 9A); fore wing in M. ctenopus light, heavily clouded at tip margin (in M. sauditus fore wing more or less subhyaline, heavily clouded subapically, Fig. 10E); gaster bright red, except brownish medially in M. ctenopus (in M. sauditus gaster entirely red, Figs 8A, 9C, D). Based on de Andrade (1954): M. sauditus differs from the male M. ctenopus in the following aspects: free margin of clypeal lobe normal (Fig. 8C) (depressed medially and slightly raised at the sides in M. ctenopus); spines of tarsal comb thin (not spatulate) (spatulate in M. ctenopus); lower edge of the apical zone of gonoforceps distinctly curved (Fig. 10D) (not markedly curved in M. ctenopus, see de Andrade (1954: 11, fig. 25)); gonoforceps with dense long setae that are distinctly bent or curved medially (Fig. 10D) (somewhat irregularly wavy in M. ctenopus; see de Andrade 1954: 11, fig. 25).

Masi (1944) saw a male of Braconella and suggested that it was B. minor, however, he had some doubts as it differed substantially from the female he examined. Here we considered our specimen as being the unknown male of B. minor and describe it for the first time. The specimen examined here resembles the Tanzanian female described by Brues (1924), except for the following: metasoma with T1, base of T2 broadly, and posterior margin of T2���4 thin ivory white to pale yellowish (Fig. 2B) (in female the metasoma to apex of T5 ferruginous); vein r 0.3�� as long as vein 3���SR (Fig. 2A) (two-thirds as long as 3���SR in female); vein SR1 distinctly longer than veins r and 3���SR combined (Fig. 2A) (as long as both veins combined in the female)., Published as part of Abu El-Ghiet, Usama M., Edmardash, Yusuf A. & Gadallah, Neveen S., 2022, New species and records of braconid wasps from Farasan Archipelago (Jazan) Saudi Arabia, with notes on Diolcogaster mayae Shestakov, pp. 49-79 in Zootaxa 5104 (1) on pages 52-54, DOI: 10.11646/zootaxa.5104.1.3, http://zenodo.org/record/6257841, {"references":["Szepligeti, G.

Afghanistan, Algeria, Armenia, Azerbaijan, Iran, Israel-Palestine, Kazakhstan, Mongolia, Romania, Russia, Tajikistan, Turkmenistan, Uzbekistan, Yemen (Ghafouri Moghaddam et al. 2019). Remarks. In the present study, the genus Diolcogaster is recorded for the first time for the fauna of Saudi Arabia. Characters of the Saudi Arabian specimen agree with those of D. mayae in the key of Ghafouri Moghaddam et al. (2019, alternative of couple 3, p. 100), as well as Table (3) (p. 106). The species is known by its high intraspecific variability (colour and measurements), in which three forms (A���C) were recorded in the Iranian fauna (see Ghafouri Moghaddam et al. 2019), as well as other hot countries including Yemen. We designate this Saudi Arabian specimen of D. mayae as form D. It is closest to form B, but differs from form B in the following: head black, with face behind antennal bases ferruginous, with a yellow longitudinal streak extending a distance from antennal bases to clypeal base (Fig. 7A) (entirely black in form B of Iran, see Ghafouri Moghaddam et al. (2019), Fig. 11D, p. 113); mesosoma yellow, slightly darker on mesoscutum and middle of scutellum (Fig. 7D), while propodeum honey yellowish (Fig. 8C) (brownish on mesosoma and dark brown on propodeum of Iranian specimens, see Ghafouri Moghaddam et al. (2019), Figs 12A, B, p. 114); pterostigma clear honey yellow (Fig. 8B) (dark brown in the Iranian specimens, see Ghafouri Moghaddam et al. (2019), Fig. 12F, p. 114); metatibia clear yellow, somewhat whitish at basal third (Fig. 6B) (reddish yellow in the Iranian form); antenna shorter than body, 0.82�� as long as body (Fig. 6A) (longer than body in the Iranian form); metasomal T3 without any trace of median field (Fig. 8D) (with weak median field in the Iranian form). These are in addition to morphometric differences provided in Table 1. On the other hand, giving the proximity of Farasan Islands (Jazan) with Yemen, and that form A of D. mayae is the only form collected from Yemen (Ghafouri Moghaddam, pers. comm.), a comparison of our specimen with form A (Ghafouri Moghaddam et al. 2019), shows that they are completely different by the predominance of black on the body; the pale spot on pterostigma of fore wing; and the bicoloured metatibia (see Figs 7���10, Ghafouri Moghaddam et al. 2019). Extensive studies should be carried out on this species as a great deal of morphological variation is seen among samples studied from the Arabian Peninsula (Fernandez-Triana, pers. comm.), and is likely to be a species complex. Due to the scarcity of specimens, we considered our specimen to be another form of D. mayae. There are many differences in morphometric measurements (see Table 1) between our Saudi Arabian specimen and the forms in Ghafouri Moghaddam et al. (2019)., Published as part of Abu El-Ghiet, Usama M., Edmardash, Yusuf A. & Gadallah, Neveen S., 2022, New species and records of braconid wasps from Farasan Archipelago (Jazan) Saudi Arabia, with notes on Diolcogaster mayae Shestakov, pp. 49-79 in Zootaxa 5104 (1) on pages 59-60, DOI: 10.11646/zootaxa.5104.1.3, http://zenodo.org/record/6257841, {"references":["Shestakov, A.

In the present study, the subfamily Gnamptodontinae is recorded for the first time for the Arabian Peninsula from Farasan Islands (Jazan, Kingdom of Saudi Arabia). The specimen does not agree with any of the Afrotropical species included in van Achterberg���s key (1983), or those of Fischer���s (1987). However, because of the bad condition of the specimen, we have refrained from allocating a species name until more specimens are collected., Published as part of Abu El-Ghiet, Usama M., Edmardash, Yusuf A. & Gadallah, Neveen S., 2022, New species and records of braconid wasps from Farasan Archipelago (Jazan) Saudi Arabia, with notes on Diolcogaster mayae Shestakov, pp. 49-79 in Zootaxa 5104 (1) on pages 56-57, DOI: 10.11646/zootaxa.5104.1.3, http://zenodo.org/record/6257841, {"references":["Fischer, M.

The genus Yelicones is a first record for the fauna of Saudi Arabia. Characters of the Saudi Arabian specimen agree well with the Omani specimen in Quicke & Chishti���s key (1997, couplet 7, p. 78), except for: shortest distance between hind ocelli 0.9�� to nearly as long as distance between hind ocellus and eye (in Omani specimens, 1.8-2.5��); length of head behind eye 0.52�� as long as horizontal length of eye (measured perpendicular to plane of face) (In Omani specimens, 0.65��); the general body colour which is uniformly reddish yellow in the Omani specimens (in Saudi Arabian specimen, head and mesosoma dark reddish yellow with some parts ferruginous, metasoma orange). It also agrees with Papp���s key (1992, couplet 6, p. 155), as well as Papp���s description (1992, p. 152). It differs from the Tanzanian specimens (Papp 1992) in the following: temple 0.3�� as long as eye height (0.5�� in Tanzanian specimens); pterostigma 3.0�� as long as wide (2.64�� in Tanzanian specimen); vein r 1.6�� as long as pterostigmal width (slightly longer than pterostigmal width in Tanzanian specimens); SR1 4.0�� as long as 3���SR (4.5-5.0�� in the Tanzanian specimens); posterior width of T1 2.4�� as wide as its basal width (twice in the Tanzanian specimens). In addition to the above-mentioned references. Our specimen is compared with coloured photos of Y. vojnitsi from Egypt, Gambia and Namibia (British Museum of Natural History (London) (NHML)). All specimens are in bad condition, however, the main difference that could be seen is the general body colour, which is yellowish red (except black stemmaticum), while in our specimen, head and mesosoma are dark red, with some parts ferruginous, and metasoma light yellowish red., Published as part of Abu El-Ghiet, Usama M., Edmardash, Yusuf A. & Gadallah, Neveen S., 2022, New species and records of braconid wasps from Farasan Archipelago (Jazan) Saudi Arabia, with notes on Diolcogaster mayae Shestakov, pp. 49-79 in Zootaxa 5104 (1) on page 64, DOI: 10.11646/zootaxa.5104.1.3, http://zenodo.org/record/6257841, {"references":["Papp, J.
