5C3AAE49D87F3C5F63BE6F5FFAF327FF.taxon	discussion	Remark: In former reviews of Crabronidae from the UAE (Schmid-Egger, 2011, 2014), specimens of Didineis from Wadi Bih were identified as D. bucharica with the key of Nemkov (2015). In the meantime, we could examine two males and two females of true D. bucharica from Russia, Kalmykia (see Mokrousov et al. (2016) for location and discussion of species). The specimens from the UAE differ in some important details from the Russian specimens, and belong to an undescribed species. A male was choosen as the holotype, because the description of D. bucharica is also based on a male. D. bucharica is restricted in its distribution to southern Russia (Dagestan, Kalmykia and Orenburg Prov.) and to Uzbekistan.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

Remaining species have longer and normally rounded flagellomeres. Females of both species have also short and thick flagellomeres, but they share this character with other species from North Africa. See also Nemkov (2015) for further details. For distincion of D. bucharica and D. mokrousovi, see Table 1.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8783C5A63BE6B3CFCCF27BE.taxon	diagnosis	Diagnosis. Gastrosericus albidaaensis is a member of the G. moricei species group (characterized by appressed setae on gena, by bristle-like appressed setae on pygidial plate and by a patch of long setae on some sterna in males). The female can be recognized by a special character combination: clypeus with medial emargination, its apical clypeal margin only slightly prominent medially (distinctly prominent in G. thoth Pulawski from Egypt), and hindtarsomere V as long as hindtarsomere II. Hindtarsomere V is shorter in the similar G. sanctus Pulawski, and the clypeus is partly yellow in the latter and black in G. albidaaensis. The species also differ from related species by its larger body size (see description). The male is characterized by a pointed tooth on apical clypeal margin, and by large patches of long white appressed pubescence on sterna III and IV. Sternum VII is rounded apically.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8763C5663BE69E6FB3D23DC.taxon	discussion	Remarks. The species was mentioned in Schmid-Egger (2011) as G. eremicus Pulawski, 1995. Pulawski (1995) mentions an aberrant female of G. funereus from United Arab Emirates and gives a figure of the clypeus. Another female from Barqa al-Saqoor in the UAE agrees with the “ aberrant ” specimen. It is clearly distinguishable from true G. funereus from Iran (several specimens from the Kerman province were examined, in coll. CSE). The main difference is the form of lateral lower pronotum near propleuron. Shape of clypeal teeth also characterizes the female well (see. fig. 45 b and 45 e in Pulawski, 1995). Consequently, we describe this specimen as new. We also could examine other specimens from Dhofar in southern Oman. They agree with fig 45 d in Pulawski (1995), also described as ” aberrant ” specimen. These belong to a further, third species of this lineage. This species is described elsewhere (Schmid-Egger & Al-Jahdhamdi under prep.). We choosed the specimens from Iran as true “ G. funereus ”, because they agree with the description of Pulawski (1995) of type specimens from Turkmenistan, and is also closer to the type area than the Arabian specimens.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8763C5663BE69E6FB3D23DC.taxon	diagnosis	Diagnosis. Gastrosericus barqaalsuqoorensis is a member of the G. funereus species-group which is characterized in females by a shiny pygidal area in combination with a deeply sulcate pronotum and two teeth or a lamella on clypeal disc. The female of G. barqaalsuqoorensis is well characterized by the special form of lower margin of propleuron (latero-dorsal view, below the lateral pronotal edge). It is wing-like prolonged versus head, and normally rounded in other species. Teeth of clypeus are small and triangular, and lamelliform or otherwise in other species. Propleuron near hindmargin has on each side a large, triangular tooth, directed backwards. Abdomen is red in G. barqaalsuqoorensis as in G. funereus, and black in the new species from Oman. The new Omanian species is also characterized by the lack of the lateral pronotal edge and a rounded lower gena. Both G. funereus and G. barqaalsuqoorensis have a distinct lateral pronotal edge, and a clear edge between underside and lateral side of gena. The male differs from true Iranian G. funereus by a rectangular medial tooth of clypeus. It is widely obtuse in G. funereus and the new species from Oman.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8703C5263BE6ADEFB132750.taxon	discussion	Discussion. It is difficult to determine the male / female relation amoung the new described species, because we found only two single males from locations different from these of the females, and both males cannot be assigned assuredly with the females by morphology. The male which is assigned here to G. pulawski comes from the Hajar mountains in eastern UAE (Wadi Wurayah), and the female paratype also from the same mountains, but in eastern Oman, whereas the holotype female originates from near to Dubai. Nevertheless, this male is assigned to the female of G. pulawskii.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

Gastroceriucus pulawskii is a member of the G. moricei species group (characterized by appressed setae on gena, and by bristle-like appressed setae on pygidial plate in female) and can be recognized by an all red mesosoma and by a sharp longitudinal keel on pronotum laterally. Remaining species have a black mesosoma, and pronotum is rounded laterally. The clypeus bears two shiny transverse swellings near apical margin, which is also unique in the species group. The male differs by a larger body size, by evenly red legs (partly whitish in G. moricei), by a red clypeus (yellow in G. moricei and by an apically emarginate sternum VII, which is rounded G. moricei.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D86F3C4D63BE6ADEFD4A272C.taxon	diagnosis	Diagnosis. Gastrosericus sheikhae is a member of the G. waltlii species group (characterized by erect and semierect setae on gena). The female can be recognized by all red legs and abdomen and by an obtuse angled clypeal lamella. The mesosoma is partly red. The related G. waltlii has at least black femora and a partly or all black abdomen. In G. sheikhae setae of gena may also be appressed and not erect, but this can result from preservation of specimens in ethanol. Specimens with appressed pilositiy on gena can be confused with G. albidaaensis. The latter differs by a prolonged apical clypeal margin, which is short and medially emarginate in G. albidaaensis. Male sterna III and IV of G. sheikhae each have a large impression, covered with patch of long setae. This impression does not reach apical sternal margin, and is distinctly separated by a sharp margin from remaining sternal surface. The species shares this special character with G. waltlii. Both are similar and differ mainly by gastral colour. It is red in G. sheikhae and dark in G. waltlii.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8683C4A63BE6A96FB51242B.taxon	discussion	Remark. Odontosphex is a small and rarely collected genus with six described species worldwide. The genus and its taxonomic position were restudied by Bohart and Menke (1976), who placed the genus in its own tribe Odontosphecini within the subfamily Philanthinae. Melo (1999) placed the genus into the subfamily Pemphredoninae, tribe Psenini. Recently, Sann et. al. (2018) confirmed this result and placed the genus as a sister group of Psenini in their new family Psenidae, based on genetic data. Recently, Mokrousov & Proshchalykin (2021) described a new species, O. leleji from Turkmenistan, and gave a key to species and further description of the genus. A single male of Odontosphex, collected in 2015 in the UAE and first recognized as an undescribed species, agrees with the description of O. leleji and confirms the occurence of the species in Arabia.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

They most probably also refer to O. leleji. O. bidens was described from Mauritania and is only known from West Africa. The third old world species, O. damara Pulawski, 1991 is only known from Namibia and will not occur in the Palearctic or Saharan region.

5C3AAE49D8663C4563BE6ECFFEF92692.taxon	description	The present sample includes a large number of Parapiagetia species with three undescribed species. For that reason, a new key for all Arabian species is given. It includes most species which are mentioned from Arabian peninsula by Gadallah (2020). However, some species were probably misidentified and do not occur in Arabia. The records of Parapiagetia odontostoma in Gadallah (2020) may refer to P. arabica, and those of P. erythropoda may refer to P. huwroberts Schmid-Egger, sp. nov. Another missidentified species is P. mongolica, which actually is P. alwathbaensis Schmid-Egger, sp. nov. Parapiagetia mongolica is not included in the key. See Gadallah (2020) for citations of these species. The females of P. kroupai and of P. haladai are unknown. However, we could examine a female from Oman with a unique character combination. It may represent the unkown female of P. haladai. It will be treated and described in detaileed in a later publication (Schmid-Egger & Al-Jahdhami in prep.), but was included in the key. Remaining Palearctic species can be identified with Pulawski (1977). The species distribution in the key is only given for Arabia, see also Pulawski (1977) for general distribution. Species already described and figured in Schmid-Egger (2011, 2014) are not mentioned in detail, because no new records were available, apart from P. arabica. For terminology of wing venation see Pulawski (1977).	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8643C4763BE6ADEFDDF21A1.taxon	discussion	Remarks. Parapiagetia alwathbaensis keys out with Parapiagetia mongolica in the key of Pulawski (1977). However, a detailed comparisation with the description in Pulawski (1977) and with true P. mongolica from Morocco shows some minor differences in morphology, and a distinctly different male genitalia. For that reason, the species is decribed here as new. P. mongolica is widely distributed in North Africa and Central Asia, and lacks in Arabian peninsula.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8643C4763BE6ADEFDDF21A1.taxon	diagnosis	Diagnosis. Parapiagetia alwathbaensis is close to P. mongolica. Both species are mainly characterized by a short marginal cell (AT as long as AR). This character is also best suited for distinction from P. arabica. The females of both species are also characterized by two long medial teeth on clypeus, and a straigth lateral margin. The lateral margin bears a short tooth in P. arabica, and a long tooth in P. odontostoma (both species also with two long medial teeth). The female of Parapiagetia alwathbaensis differs from the similar P. mongolica by the pubescence of the face. It reaches ocellar region or vertex in P. alwathbaensis, and ends more or less in the middle between antennal base and midocellus in P. mongolica. The male differs from P. mongolica mainly by the shape of the volsella which is as narrow as penis valve in P. alwathbaensis (lateral view), and twice as large as penis valve in P. mongolica. Also, the volsella is evenly curved downwards in P. alwathbaensis, and more or less straight in P. mongolica. Longest setae on ventral margin of the volsella are longer than the diameter of the volsella in P. spec. A from Oman, and much shorter and restricted to the medial part of the volsella in P. mongolica.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8633C4363BE6885FB932365.taxon	discussion	Remarks. Schmid-Egger (2011) published Parapiagetia species from the UAE as P. erythropoda. More detailed examination and comparisation with other specimens of the P. erythropoda lineage from different localities in Africa, Iran and India show that the UAE specimens belong to an undescribed species. P. erythropoda sensu Pulawski (1977) comprises some different and clearly distinghuishable species, which are already described and are currently synonymised with P. erythropoda. In our opinion, P. erythropoda s. str. is restricted to Iran, India and adjacent countries, whereas the African taxa belong to different species. The topic will be treated in a separate contribution.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.

5C3AAE49D8633C4363BE6885FB932365.taxon	diagnosis	Diagnosis. Parapiagetia huwrobertsi is a member of the P. erythropoda lineage. The females of this lineage are characterized by a shiny surface of forecoxal venter, which is separate from the fore margin by a carina. The forecoxa is evenly rounded in other species groups. Parapiagetia huwrobertsi has an all red abdomen (apically black in remaining species of the P. erythropoda lineage) and two teeth on clypeal lobe near apical margin, which are directed downwards. In the remaining species these teeth are located near the middle of clypeal disc and directed forewards, and therefore prominent in lateral view. The male differs from males of P. erythropoda s. str and from P. saharica de Beaumont mainly by colour. Abdomen and femora are uniformily greyish in P. huwrobertsi and black with first terga and some or all femora red in the other species. The species is the largest of the genus in the Arabian Peninsula.	en	Schmid-Egger, Christian, Harten, Antonius Van (2022): Additions to the digger wasps (Hymenoptera, Spheciformes) of the United Arab Emirates with description of ten new species.
