Description. Holotype. Male. Length 3.2 mm. LFW 3.4 mm.

Colors. Body castaneous; antenna gradually darker distally; mandible castaneous; foreleg castaneous, others light yellowish; wings hyaline, veins castaneous.

Head. Head as long as wide, trapezoidal. Frons coriaceous, densely puncticulate; frontal line absent. Vertex slightly convex. Clypeus broad with median lobe subtrapezoidal, median tooth present, and large, apical margin crenulate, median carina short in profile. Mandible with three apical teeth, teeth with different size, upper tooth mesad, uppermost much smaller than others. Eye weakly bulging. Ocelli large, triangle with distal edges.

Mesosoma. Dorsal pronotal area long. Notaulus absent. Parapsidal signum well delimited. Mesoscutellum longer than large, posterior margin convex; mesoscutum-mesoscutellar sulcus weakly arched, narrow, shallow, without fovea on side edge. Axilla subtrapezoidal, deep, large. Metanotal trough mostly imbricate, with few foveae, metanotal fovea oval; median region narrow, large, with posterior margin straight. Metapectal-propodeal complex short, posterior margin almost straight; metapostnotal median carina absent, metapostnotum row of anterior foveae, polished and weakly imbricate. Metapectal-propodeal complex weakly imbricate; Paraspicular sulcus polished; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum imbricate, inferior region foveolate. Propodeal declivity polished-imbricate.

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

Female. Unknown.

Comments. The trapezoidal head and the mostly polished metapostnotum with texture differentiating only anteriorly of A. joela  are similar to those in A. azeda  . However, A. joela  has the clypeus with a large median tooth; the mandible with three teeth and the cuspis with three apical calli, whereas A. azeda  has the clypeus with a small median tooth; the mandible with four teeth and the cuspis with two apical calli.

Distribution. Australian ( New Caledonia).
