( Figs 4BView FIGURE 4, 6HView FIGURE 6, 8IView FIGURE 8, 11HView FIGURE 11, 14CView FIGURE 14, 20View FIGURE 20 G–I)

Description. Holotype. Male. Length 3.9 mm. LFW 3.8 mm.

Colors. Body dark castaneous; mandible yellowish; legs castaneous and yellowish; wings hyaline, veins castaneous.

Head. Head wider than long, trapezoidal. Frons coriaceous, sparsely puncticulate; frontal line absent. Vertex slightly convex. Clypeus broad with median lobe subtrapezoidal, median tooth small, apical margin crenulate, median carina short in profile. Mandible with four apical teeth, teeth with different size, upper tooth mesad, three upper teeth equally sized. Eye weakly bulging. Ocelli large, triangle with distal edges.

Mesosoma. Dorsal pronotal area very short. Notaulus present, complete, strongly converging posterad. Parapsidal signum weakly impressed. Mesoscutellum longer than large, posterior margin almost straight; mesoscutummesoscutellar sulcus almost straight, narrow, shallow, without fovea on side edge. Axilla subtrapezoidal, deep, large. Metanotal trough mostly imbricate, with few foveae, metanotal fovea drop-shaped; median region wide, narrow, with posterior margin straight. Metapectal-propodeal complex long, posterior margin almost straight; metapostnotal median carina present, metapostnotum rugulose, and polished. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum imbricate, inferior region foveolate. Propodeal declivity foveolate.

Metasoma. Petiole short. Hypopygium with plate long, posterior margin almost straight, flap absent. Genitalia: paramere straight. Basivolsella apical inner margin projected mesad, large, and convex. Basiparamere with apical dorsal projection large, apex convex. Cuspis with apical margin with two apical calli, ventral larger than other, dorsal end short. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe long; subapical membrane absent; aedeagal dorsal cover wide.

Female. Unknown.

Material examined. Holotype ♂, MALAYSIA, Pasoh Forest Res. Negri S., X.14.78, sec. for., P. & M. Becker ( AEIC). 

Comments. This species is similar to A. beliella  by having the notaulus complete and the metapostnotum rugulose. However, A. beliella  has the mandible with five teeth; the mesoscutum-mesoscutellar suture strongly arched and deep; the hypopygium with flap and posterior margin concave, whereas A. itoiela  has the mandible with four teeth; the mesoscutum-mesoscutellar suture straight and shallow; the hypopygium without flap and posterior margin almost straight.

Distribution. Oriental ( Malaysia).
