Diagnosis. The species belongs to the Astrotischeria trilobata  group. The combination of the very slender and long lobes of uncus, and the unique dorsal lobes of valva in the male genitalia (see Fig. 13View FIGURES 11–15) distinguishes A.occidentalis  from all other Astrotischeria  , including other members of the A. trilobata  group. The fact that it feeds on Aster also makes this species distinctive.

Male. Wingspan about 7–8 mm. For a description see Braun 1972: 73, 74.
