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.
