Mesosoma (Fig. 8): thorax polished. Pronotal disc without anterior carina. Notauli complete, narrow anteriorly. Parapsidal furrows incomplete anteriorly. Propodeal disc 1.38 X as wide as long, polished, with only anterior carina present, declivity polished.

Metasoma: petiolate, petiole very short 0.1 X as long as tergite I. Genitalia (Fig. 10): paramere long and somewhat slender, surface wholly hairy, apex only slightly larger than base, apical margin inclined with outer corner rounded and higher than inner portion; basiparamere with elongate process arising from apical margin dorsally; volsella with the ventral ramus of digitus narrow, with the apex rounded and very hairy; volsella with the ventral ramus of digitus situated at cuspis base, with apex very hairy, inner margin of basivolsella dilated; aedeagus with two pairs of apical lobes, the lateral pair large, rounded and membranous, and directed downward, the median pair sharp and very small.

Remarks. — This species is very similar to A. laevigata (Evans, 1958), however this species shows some different characteristics: head with vertex broadly straight, clypeus with rounded median lobe, genitalia with median region of aedeagus narrow, whereas A. laevigata has head with vertex broadly rounded, clypeus with emarginate median lobe, and the genitalia with two additional short processes arising near base of the parameres, and median region of aedeagus larger.

Etymology. — The name refers to the morphological pattern that is different from the other species of this genus.
