To me, your ID sounds good! The abdomen shows the 'hockey-stick'-shaped markings, and on the mesonotum the two pale stripes are joined across the middle, as described in the key by Speight (1981) (see https://www.jstor...b_contents). A similar species, A. transfuga, lacks the 'wasp-waisted' abdomen that is typical for A. contracta, caused by the distinctly concave side margins of tergite 2. In the lower picture of your female one can see this shape of tergite 2, which is also narrower than long. So A. contracta should be OK.
