Metasoma ( Figs. 38, 39 ) distinctly elongate, length 3.3–3.6 times width; length of T1 equal to width; length of T2 0.6 times width; length of T3 0.6 times width; length of T4 0.6 times width; length of T5 0.5 times width; all five basal tergites with longitudinal costae, some irregular rugulae at sides; width of T6 0.6 times length; tergites beyond T6 extremely small, length of T7 0.3 times width, length of T8 0.6 times width.

Diagnosis: The female is differentiated from the other flightless species, A. pygmea and A. submetallica , by the presence of short stubs of wings, deeply incised and foveolate notaulus, well-developed and foveolate transscutal articulation, and the elongate metasoma with pairs of longitudinal sublateral depressions on T2– T5. The male is distinguished from most Chilean species by the elongate, tracheate postmarginal vein, a character shared with A. pygmea and A. robusta . From those two species the male may be distinguished by the well-developed notauli (absent in A. pygmea ) and the gentle, but distinct bowlike curving of antennomeres 5– 8 (straight and cylindrical in the other two species).

Etymology: The specific epithet dispar, Latin for unlink or different, stresses the strong secondary sexual dimorphism of the males and females.
