Diagnosis.

Third tergite flat medially, broadly truncate posteriorly in dorsal view (Fig. 31 ) and acute posteriorly in lateral view (Fig. 32 ); apical antennal segments of ♀ rather slender (Fig. 39 ) and 3 apical segments moniliform; head directly narrowed behind eyes (Fig. 35 ); inner tooth of mandible ca. 0.5 × apical tooth, stout (Fig. 34 ); vein r of fore wing vertical (Fig. 29 ); vein r of fore wing ca. 0.7 × as long as vein 3-SR; mesoscutum coriaceous-like sculptured; vein 1-R1 ca. 1.2 × as long as pterostigma; vein 1-M of fore wing brown); mesosoma approx. twice longer than high in lateral view; hypopygium of ♀ with narrow and long spine-like protuberance apically (Fig. 32 ).

Description.

Female, holotype, length of body (excluding ovipositor) 3.4 mm; antenna 2.5 mm; fore wing 2.2 mm; visible part of ovipositor sheath 0.7 mm (0.15 mm sparsely erect setose).

Head. Width 1.6 × median length in anterior view and part of head above eye in lateral view 0.2 × height of eye (Fig. 37 ); antenna with 23 cylindrical segments and 1.1 × longer than fore wing, three apical segments small and moniliform (Fig. 39 ), with short bristle apically and apical segment without spine, third, fourth and penultimate segments 3.0, 2.8 and 1.0 × longer than wide in lateral view, respectively; area of stemmaticum granulate; OOL: diameter of posterior ocellus: POL = 12: 4: 4; length of eye 3.1 × temple in dorsal view (Fig. 35 ); frons granulate medially, rugose laterally and without median carina; vertex rugose and with satin sheen; temple finely and densely granulate and rather dull, directly narrowed behind eyes; face transversely rugose laterally, rugulose and with obsolescent median bump and rather shiny; clypeus smooth, shiny and 0.8 × minimum width of face, intertentorial distance 2.6 × minimum width between clypeus and eye, long erect setose and with 3 indistinct blunt teeth medio-ventrally (Fig. 36 ); eye medium-sized, strongly convex and in lateral view 1.7 × (measured medially) wider than temple (Fig. 37 ), in anterior view its height equal to minimum width of face; upper condyle of mandible near lower level of eyes (Fig. 36 ); malar space aciculate, with satin sheen and 0.4 × as long as basal width of mandible; lower tooth of mandible half as long as apical tooth, robust (Fig. 34 ).

Mesosoma (Figs 28 , 30 ). Length 2.1 × its width in lateral view; side of pronotum rugose, but anteriorly punctate and dorsally granulate; propleuron posteriorly flattened; mesosternum superficially granulate and with satin sheen; mesoscutum densely and very finely rugulose, rather dull; scutellum flat, distinctly granulate (but medially partly smooth) and rather matt; scutellar sulcus narrow, with nine carinae (Fig. 30 ); metanotum with short median carina medially and finely serrate posteriorly; propodeum rugose, but anteriorly rugulose, without transverse carina or median carina, and latero-posteriorly weakly tuberculate. Wings. Fore wing 2.7 × longer than its maximum width; 1-R1 1.25 × as long as pterostigma; distance between wing apex and marginal cell apex 0.2 × length of 1-R1; r issued far beyond middle of pterostigma and 0.7 × 3-SR; 2-SR slightly curved and subparallel with posterior margin of pterostigma (Fig. 29 ); SR1 straight; 2-SR+M short; m-cu just postfurcal; parastigma medium-sized; 1-CU1 0.4 × as long as vein 2-CU1, cu-a 0.8 × 1-CU1; r:3-SR:SR1 = 5:7:34; 2-SR:3-SR:r-m = 18:7:7; r-m nearly vertical; 2-M slightly curved (Fig. 29 ). Hind wing: M+CU:1-M:1r-m = 16:14:5. Legs. Hind femur matt, 3.1 × as long as wide and robust; middle tibia with ivory blister; inner spur of middle tibia 0.4 × its basitarsus; hind tibia wide medially (Fig. 33 ); hind coxa largely coriaceous but dorsally mostly smooth and shiny.

Metasoma (Figs 31 , 32 ). Nearly parallel-sided in dorsal view, 1.9 × as long as wide and 1.4 × as long as mesosoma; first and second tergites densely and coarsely longitudinally rugose; second metasomal suture rather wide and slightly sinuate; third tergite 1.3 × longer than second tergite and straight, flat medially, broadly truncate posteriorly in dorsal view (slightly concave: Fig. 31 ), acute posteriorly in lateral view (Fig. 32 ), reticulate-rugose and with satin sheen (Fig. 31 ), lateral lamella narrow, wider latero-apically and medio-apically narrow; ovipositor sheath narrow, apically somewhat widened and darkened, its visible part 0.32 × as long as fore wing and 0.58 × metasomal carapace and sparsely setose part 0.07 × fore wing and with few erect setae; hypopygium of ♀ with long narrow triangular and spine-like protuberance apically (Fig. 32 ) and rather sparsely setose.

Colour. Yellowish brown (including most of hind femur); apex of antenna, hind tibia apically and subbasally, parastigma, vein 1-M and apex of ovipositor sheath brown; stemmaticum dark brown; clypeus, palpi, tegulae, remainder of legs first and second tergites and metasoma ventrally pale yellowish or ivory; pterostigma (but basally and apically pale yellowish) dark brown; wing membrane slightly brownish below pterostigma.

Male.

Biology.

Unknown.

Distribution.

Yemen.

Etymology.

From aspidiotes (Greek for shield-bearer) because of the truncated shield-like third metasomal tergite.
