Agorius constrictus is a species of ant mimicking jumping spider from Singapore.

The orange-brown cephalothorax is about twice as long as wide, with its posterior edge forming a transverse depression behind the rear eyes.

The very long opisthosoma mimics the shape of certain ants, with a small dark oval anterior part, a slender whitish "waist" and a large dark oval posterior part.

The long slender legs are lightish orange.
