Clypeus broad with median lobe subtrapezoidal, median tooth present, and large, apical margin smooth, median carina short in profile. Mandible with five apical teeth, teeth with different size, upper tooth mesad, four upper teeth equally sized. Eye weakly bulging. Ocelli large, triangle with distal edges.

Metanotal trough imbricate, metanotal fovea oval; median region wide, large, with posterior margin straight. Metapectalpropodeal complex short, 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 present; lateral surface of propodeum imbricate, inferior region strigulate. Propodeal declivity polished-imbricate.

Metasoma. Petiole short. Hypopygium with plate long, posterior margin concave, flap present. Genitalia: paramere slightly sinuous. Basivolsella apical inner margin projected mesad, large, and acute. Basiparamere with apical dorsal projection large, apex acute. Cuspis with apical margin with two apical calli, ventral wider than other, dorsal end very short.

Comments. Apenesia beliella  is similar to A. itoiela  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 a flap and the posterior margin concave, whereas A. itoiela  has the mandible with four teeth; the mesoscutum-mesoscutellar suture straight and shallow; the hypopygium without a flap and the posterior margin almost straight.

Distribution. Oriental ( Thailand, Indonesia, Malaysia) and Australian ( Vanuatu).
