Clypeus broad with median lobe subtrapezoidal, median tooth present, and large, apical margin crenulate, median carina high in profile. Mandible with three apical teeth, teeth with similar size, upper tooth mesad. Eye weakly bulging. Ocelli large, triangle with distal edges.

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

Metasoma. Petiole short. Hypopygium with plate short, posterior margin almost straight, flap absent. Genitalia: paramere slightly sinuous. 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 long. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe short; subapical membrane short; aedeagal dorsal cover wide.

Description. Allotype. Female. Length 5,5 mm. Body light castaneous, metasoma castaneous. Mandible with three apical teeth. Clypeus extending back frons, median lobe with apical margin strongly concave, so that clypeus is nearly absent medially, apical margin with bristles, median carina absent. Eye grey, elliptical, with about 6 facets. Malar space wider than eye length. Frons aciculate, punctures sparse. Head quadrate with sides parallel, vertex slightly concave, 1.1 × as long as wide. Dorsal pronotal area with sides nearly parallel, anterior margin with median emargination. Maximum width of metapectal-propodeal complex 1.8 × its minimum width. Mesopleuron with longitudinal carina dividing dorsal and lateral faces. Mesotibia strongly spinose. Metasoma longer than head and mesosoma together, petiole very short.

Comments. According to label data, some males and females of this species were reared from larvae of the Curculionidae  beetle, Pantorhytes plutus Faust, 1892  . This species is similar to A. azeda  by having the notaulus absent; the pronotum short; the metapostnotum almost all polished and the basivolsella apical inner margin projected and convex. Although males of A. azeda  have the head as long as wide; the mandible with four teeth; the metanotal groove foveolate with a linear median fovea; the metapectal-propodeal complex with the posterior margin convex; the metapostnotum with a row of anterior fovea; the hypopygeal posterior margin concave and females with two teeth, whereas males of A. celiela  has the head longer than wide; the mandible with three teeth; the metanotal groove mostly imbricate; the metapectal-propodeal complex with the posterior margin almost straight; the metapostnotum with a row of striae; the hypopygeal posterior margin almost straight and females with three mandibular teeth.

Distribution. Oriental ( Indonesia, Malaysia); Australian ( Papua New Guinea).
