Diagnosis. Head (except black stemmaticum), mesosoma and posterior end of metasoma brownish in colour ( Figs 15A, B View FIGURE 15 , 17D View FIGURE 17 ); scapus slightly, but distinctly oblique apically, longer dorsally than ventrally ( Fig. 16A View FIGURE 16 ); OOL about as long as diameter of posterior ocellus; occipital carina well seen ventrally, weak dorsally, reaching hypostomal carina; notauli absent on mesoscutum ( Fig. 16D View FIGURE 16 ); vein 2–CU1 of fore wing 2.9 × as long as 1–CU1 ( Fig. 17A View FIGURE 17 ); vein 1–SR very short, connected with vein 1–M at the same level ( Fig. 17A View FIGURE 17 ), vein 1–M slightly curved posteriorly ( Fig. 17A View FIGURE 17 ); metasomal T4 superficially granulate to nearly smooth ( Fig. 17D View FIGURE 17 ); fore wing 2.8mm; malar space 0.2 × height of eye ( Fig. 16A View FIGURE 16 ); marginal cell of hind wing parallel-sided apically ( Fig. 17B View FIGURE 17 ); metatibia with inner comb of blunt bristles apically ( Fig. 17C View FIGURE 17 ).

Description. Holotype, ♀, length of body 3.5 mm; length of fore wing 2.8 mm.

Colour ( Figs 15A, B View FIGURE 15 , 16B View FIGURE 16 ). Head and mesosoma (except propodeum), as well as end tergites brownish, propodeum and legs straw yellow; tegula pale yellow; stemmaticum black; wings ( Figs 17A, B View FIGURE 17 ) hyaline, with pale brownish to yellowish veins, pterostigma bright yellow; antenna yellow, with apical half of flagellum brownish (apices broken).

Head ( Figs 16A–C View FIGURE 16 ).Antennae with broken flagella, scapus oblique apically, longer dorsally than ventrally; face superficially punctulate, shiny; OOL about as long as posterior ocellus diameter, finely rugose; vertex granulaterugose; clypeus somewhat convex, small, finely coriaceous, ventral margin concave; width of hypoclypeal depression 0.3× minimal width of face; face very finely granulate; occipital carina complete, but weak dorsally, meeting hypostomal carina ventrally; clypeus located slightly above lower level of eye; malar space 0.2× as long as height of eye laterally; eye distinctly bulged, with slight, but distinct emergination at uppermost part of inner orbits.

Mesosoma ( Fig. 16D View FIGURE 16 ). Mesoscutum very finely coriaceous throughout, notauli absent, posterior margin straight; mesopleuron and metapleuron very finely coriaceous-rugose throughout, rather shiny; scutellum somewhat convex, finely and superficially dotted to coriaceous, without lateral carina; propodeum finely rugose, with a complete median longitudinal carina.

Wings ( Figs 17A, B View FIGURE 17 ). Fore wing: vein r 0.45× vein 3SR; 1–CU1 slightly oblique, 0.34× as long as 2–CU1; vein r–m 0.54× vein 2–SR, and 0.34× vein 3–SR; SMC2 elongate, trapezoidal; vein 1–SR short, straight with 1–M; cu–a rather oblique, somewhat reduced ventrally; vein CU1a distinctly curved at base; vein 1–M slightly curved posteriorly. Hind wing: apical half of marginal cell parallel-sided; vein 2–SC+R very short; vein m-cu greatly reduced, as being just an unpigmented fold; M+CU 1.77× as long as 1–M; 1r–m 0.5× 1–M.

Legs ( Figs 15A, B View FIGURE 15 , 17C View FIGURE 17 ). Claws simple, setose; hind coxa superficially coriaceous; femora thin and slender; hind trochantellus 2.9× as long as ventrally as apical width; metatibia with an inner transparent comb of blunt bristles apically; inner metatibia spur 0.18× as long as hind basitarsus; two metatibia spurs nearly equal in size.

Metasoma ( Figs 17D, E View FIGURE 17 ). Metasomal T1 0.84× as long as its posterior width, flattened and lamellate laterally; T1, T2 and base of T3 finely longitudinally rugose, T1 and T2 with strong longitudinal median carina; mediobasal smooth area of T2 absent; remainder of metasomal tergites superficially coriaceous to nearly smooth. Lateral sides of metasomal tergites with fine, short whitish setae. Ovipositor sheath short, slender, tapering at end, nearly smooth.

Distribution. So far Saudi Arabia (Farasan Islands, Jazan).

Remarks. The new species closely resembles Aleiodes pallidator (Thunberg) (based on the description of van Achterberg & Shaw, 2016), but differs from A. pallidator in the following combination of characters: notauli completely absent ( Fig. 17D View FIGURE 17 ) (in A. pallidator notauli present, narrow, shallow and crenulate ( Fig. 15C View FIGURE 15 )); inner apex of metatibia with comb of transparent, blunt bristles ( Fig. 17C View FIGURE 17 ) (in A. pallidator inner apex of metatibia without comb of bristles); ovipositor sheath not densely setose, very short (hardly seen in lateral view), tapering apically ( Fig. 17E View FIGURE 17 ) (in A. pallidator ovipositor sheath densely setose, well-seen in lateral view, rounded apically).

Measurements of fore wing veins ( Fig. 17A View FIGURE 17 ): vein r 0.45× vein 3–SR (0.3× in A. pallidator ); 1–CU1 slightly oblique (horizontal in A. pallidator ); vein r–m 0.54× vein 2–SR (0.7× in A. pallidator ), and 0.34× vein 3–SR (0.4× in A. pallidator ); vein 1–SR short, straight with 1–M (angled with 1–M in A. pallidator ); cu–a rather oblique, somewhat reduced ventrally; vein CU1a distinctly curved at base; vein 1–M slightly curved posteriorly.

Etymology. The name subpallidator is named with reference to the similarity of this species to Aleiodes pallidator .
