Krusa annulata is native to Mexico. Harvestmen have a single, fused, oval-shaped body section, unlike spiders which have two distinct body segments (cephalothorax and abdomen). They possess eight legs, which are often very long and spindly. The second pair is typically longer and used as sensory organs, like antennae. They also have a pair of pincer-like mouthparts (chelicerae) used for feeding.
