Freya decorata

Koch's original descriptions of the male and female reveal the sexual dimorphism that initially led him to consider them separate species.

Male. The male measures approximately 3.5 mm in length. The cephalothorax and abdomen are deep black, each with three longitudinal snow-white stripes. The lateral stripe on the cephalothorax does not reach the side edges, leaving fairly broad black margins. The legs are rust-yellow with brown rings and white spots. The cephalothorax is of equal width and height, with the head region slightly arched toward the anterior eye row, and the eyes of this row looking somewhat obliquely downward. The chelicerae are fairly long, cone-shaped, and matte-glossy with very fine wrinkles above. The male palps have an upward-standing, curved, fairly long process on the genitalia. The abdomen is narrower than the cephalothorax and egg-shaped, with somewhat long, protruding spinnerets.

Female. The female is also approximately 3.5 mm long but differs noticeably in several features. While sharing the same basic coloration pattern of dark brown body with three yellowish-white longitudinal stripes, the female's cephalothorax has a different shape—the head is somewhat narrower, the thorax broader and more rounded at the side edges. …

F. decorata has been recorded from several countries in northern South America, including Brazil, Colombia, Ecuador, French Guiana, and Guyana.
