Diagnosis, Female. Head convex, with many very evanescent tracks of rugosities ( Figs 2E View FIGURE 2 , 4E View FIGURE 4 ); frontal line complete ( Figs 2C, E View FIGURE 2 , 4C, E View FIGURE 4 ); occipital carina complete ( Figs 2E View FIGURE 2 , 4E View FIGURE 4 ); antenna clavate ( Figs 2A View FIGURE 2 , 4A View FIGURE 4 ); pronotum anteriorly crossed by slight transverse impression ( Figs 2F–G View FIGURE 2 , 4F–G View FIGURE 4 ); notauli incomplete, very shortly visible near anterior margin of mesoscutum ( Figs 2F–G View FIGURE 2 , 4F–G View FIGURE 4 ); mesoscutum granulate, with evanescent rugosities ( Figs 2F–G View FIGURE 2 , 4F–G View FIGURE 4 ); metapectal-propodeal disc without strong transverse posterior carina, reticulate rugose; propodeal declivity without longitudinal carina ( Figs 2G View FIGURE 2 , 4G View FIGURE 4 ); forewing without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than proximal part ( Figs 2B View FIGURE 2 , 4B View FIGURE 4 ); protarsomeres in following proportions: 50:16:20:20:68; enlarged claw with proximal prominence bearing one long bristle; rudimentary claw absent; protarsomere 5 with proximal part approximately as long as distal part, with two rows of 1–7 or 2–5 lamellae ( Figs 2H View FIGURE 2 , 5C View FIGURE 5 ); apex with four lamellae; tibial spurs 1/1/2 ( Figs 2A View FIGURE 2 , 4A View FIGURE 4 ).

Diagnosis, Male. Head granulate and slightly reticulate rugose ( Figs 3C–E View FIGURE 3 ); vertex of head without two oblique keels connecting lateral ocelli to occipital carina( Fig.3C View FIGURE 3 );mesoscutum slightly granulate( Fig.3F View FIGURE 3 );notauli incomplete, reaching about 0.5 × length of mesoscutum ( Fig. 3F View FIGURE 3 ); propodeal declivity with areolae less wide than those of metapectal-propodeal disc ( Fig. 3G View FIGURE 3 ); paramere without inner process, with numerous papillae on inner side ( Fig. 6 View FIGURE 6 ).

Biology. Host unknown.

Collecting methods. Light trap, Malaise trap and sweep net.

Collecting times. Iran (June and July), Kenya (November and December), Madagascar (February and November), South Africa (February, November, and December), Tanzania (May), Yemen (March, May, June, September, October, November, December).

Geographical distribution ( Fig. 7 View FIGURE 7 ). Afrotropical [ Kenya, Madagascar, South Africa, Tanzania, Yemen]; Palaearctic [ Iran (new record)].

Remarks. Females of A. xericum from the Afrotropical region, resemble A. arabicum Olmi, 1984 , by having antenna clavate; frontal line complete; occipital carina complete; pronotal tubercle reaching tegula; propodeal declivity dull, reticulate rugose, without longitudinal carina; forewing hyaline, without dark transverse bands; distal part of 2r-rs&Rs vein much shorter than the proximal part. However, A. xericum has notauli incomplete, very shortly visible near the anterior margin of mesoscutum; mesoscutum alutaceous, with numerous longitudinal weak carinae or furrows metapectal-propodeal disc without strong transverse posterior carina, dull, reticulate rugose; protarsomere 5 proximal and a distal part of about equal length, with two rows of 1–7 or 2–5 lamellae; apex with four lamellae. Whilst A. arabicum , has notauli absent; mesoscutum granulated, with evanescent rugosities; metapectal-propodeal disc reticulate rugose, with the strong transverse posterior carina; protarsomere 5 with proximal part longer than apical part, with four lamellae and some bristles ( Olmi 1984). Also, male specimen of A. xericum is similar to A. leleji Speranza, Olmi, Capradossi & Contarini, 2021 , from Turkey ( Speranza et al. 2021).

In the Palaearctic region, A. xericum is close to A. metuendum Olmi, 1987a , from China, South Korea, and some Oriental countries ( Olmi & Xu 2015). Following the addition of A. xericum to the Palaearctic region, the key to the females of Anteon of the Eastern Palaearctic region ( Olmi & Xu 2015) can be modified by changing couplets 1–5 as follows:

1. Protarsomere 4 at most about 0.5 × as long as protarsomere 1.................................................. 2

- Protarsomere 4 as long as, or longer than, or little shorter than protarsomere 1 (in last case, at least 0.66 × as long as protarsomere 1)................................................................................................. 20 2. Propodeal declivity without longitudinal carinae............................................................. 3 - Propodeal declivity with two longitudinal carinae............................................................ 7 3. Mesoscutum dull, granulated or reticulate rugose, never unsculptured or punctate and unsculptured among punctures...... 4 - Mesoscutum shiny, unsculptured, except few weak tracks of irregular carinae on sides, or punctate and unsculptured among punctures............................................................................................ 6 4. Forewing with one weak dark spot beneath pterostigma................................. A. metuendum Olmi, 1987a - Forewing hyaline, without dark transverse bands............................................................. 5 5. Notauli reaching 0.3–0.5 × length of mesoscutum.................................... A. jurineanum Latreille, 1809 - Notauli absent or hardly visible near anterior margin of mesoscutum............................................ 5’ 5’ Protarsomere 5 with proximal part about as long as distal part.................. A. xericum Olmi & van Harten, 2006 - Protarsomere 5 with proximal part much longer than distal part........................... A. metuendum Olmi, 1987a
