Diagnosis. Female. Length 5.0 mm. Color. Body light castaneous, metasoma castaneous. Mandible with two apical teeth. Clypeus very short, median lobe with apical median margin concave, apical margin with bristles, clypeus strongly projected backward between up to top eye level, median carina absent. Eye dark, elliptical, with about eight facets. Malar space shorter than eye length. Frons aciculate, punctures small and sparse. Head elongate with sides parallel and vertex barely concave, 1.27 × as long as wide. Dorsal pronotal area with sides diverging posteriorly. Maximum width of metapectal-propodeal complex 1.8 × its minimum width. Mesopleuron with longitudinal carina dividing dorsal and lateral faces Mesotibia strongly spinose, spines wide. Metasoma longer than head and mesosoma together, petiole long.

Comments. This species is similar to A. substriata by having the mandible with two apical teeth; the clypeus very short, its median lobe with the apical median margin concave and the eye dark, elliptical, with about eight facets. However, A. unicolor has the head elongate, whereas A. substriata has the head quadrate.
