Worker ants are monomorphic and have a life cycle of 76–84 days. They have a body length of approximately 4mm, a yellow brownish colour with a darker brown gaster and remarkably long legs and antennae. They are weakly sclerotized, have an oval-shaped head, mandibles with 8 teeth and 11-segmented antennae. The mesosoma is slender, pronotum narrow, with an almost-straight dorsum in profile. The anterior portion of the mesonotal dorsum, back to the propodeum, is gently concave in profile. The propodeal dorsum is convex in profile. The petiole is thick, with an inverted-U-shaped crest. Although they cannot sting, the ants spray formic acid in defence and, while this in itself does not kill the target, it can cause blindness and lead to death by starvation in many vertebrate victims.
