Leucospidae Walker, 1834 View in CoL ): 13. Type genus: Leucospis Duméril, 1823 View in CoL (= Leucospis Fabricius, 1775 View in CoL ).

Key to leucospid species so far known or expected to occur in Saudi Arabia (based only on Bouček 1974 at the generic level; and on Schmid-Egger 2010 for L. vanharteni )

1. Clypeus produced medially at free margin, slightly arcuate ( Figure 10 View Figure 10 (c)); mandible slender, more or less rounded and slightly notched apically, with dense setae towards apex ( Figure 10 View Figure 10 (c)); in both sexes gaster strongly clavate, narrow basally ( Figures 10 View Figure 10 (a) & 11(d)); GT4 of female with hind margin obviously produced backward and sharply angulate ( Figure 11 View Figure 11 (d)); GT6 fused with syntergum ( Figure 11 View Figure 11 (c)) ................................................... .................................................. Micrapion clavaforme Steffan View in CoL

– Clypeus bilobed at free margin, with a tooth in between (e.g. Figure 6 View Figure 6 (b)); mandible robust, bare (e.g. Figure 6 View Figure 6 (b)), lower tooth always somewhat strong; gaster much less clavate ( Figures 2 View Figure 2 (c), 3(a), 7(b), & 9(d)); GT4 of female nearly straight posteriorly ( Figures 5 View Figure 5 (c) & 9(d)); GT6 distinctly separated from syntergum ( Figures 3 View Figure 3 (b) & 8(a)) (genus Leucospis View in CoL ).................................................................................................................................. 2

2. Body dark red/brown, extensively marked with pale yellow ( Figure 8 View Figure 8 (a)); dorsum of pronotum broadly yellow including the surface in front of discal carina, mesoscutellum extensively pale yellow, with narrow red/brown strip anteriorly ( Figures 8 View Figure 8 (a) & 9(b)); postscutellum evenly convex, neither carinate nor bidentate, with sparse setae ( Figure 9 View Figure 9 (b)); ovipositorial furrow longer, anterior end reaching anterior margin of GT1 ( Figure 9 View Figure 9 (d)).......................................................................... Leucospis elegans Klug View in CoL

– Body with fewer pale yellow markings; postscutellum carinate ( Figures 2 View Figure 2 (b) & 5(a)); ovipositorial furrow shorter, at most ending before anterior margin of GT1 ( Figure 5 View Figure 5 (c)) ............................................................................................................................................................... 3

3. Discal carina present on pronotum ( Figure 1 View Figure 1 (b)), sometimes faint and short; anterior end of ovipositorial furrow not reaching base of GT5.. Leucospis africana Cameron View in CoL

– Discal carina completely absent on pronotum ( Figure 3 View Figure 3 (a,b)); anterior end of ovipositorial furrow ends near either base or apex of GT1 ( Figure 5 View Figure 5 (c))................ ................ 4

4. Both wings yellow with red venation, apical third strongly infuscate; pronotum red/orange (except black at base of mesopleuron) ( Schmid-Egger 2010, p. 323, Figure 4 View Figure 4 ); middle teeth of hind femur distinctly longer than basal triangular tooth ( Schmid-Egger 2010, p. 323, Figure 6 View Figure 6 ); postscutellum with straight carinate margin; ovipositorial furrow reaching apical fourth of GT1............................................. .............................................................................. Leucospis vanharteni Schmid-Egger, 2010

– Both wings hyaline, fore wing infuscate below PMV and at apex ( Figure 7 View Figure 7 (a)); a transverse yellow strip visible posteriorly between preapical and marginal carinae, continuing to lateral panel of pronotum ( Figure 4 View Figure 4 (b)) as an oblique marking above the ventral depression of the panel; basal tooth of hind femur longer and more robust than any of the following teeth ( Figure 4 View Figure 4 (c)); postscutellum with curved carinate margin; ovipositorial furrow ending near to base of GT1..................................... ......................................................................
