The<unk>  or pubic<unk>  (Pthirus pubis) is an insect that is an obligate ectoparasite of humans, feeding exclusively on blood. The<unk>  usually is found in the person's pubic hair. Although the<unk>  cannot jump, it can also live in other areas of the body that are covered with coarse hair, such as the perianal area, the entire body (in men), and the eyelashes (in children). Humans are the only known hosts of the<unk> , although a closely related species, Pthirus gorillae, infects gorillas. The human parasite is thought to have diverged from Pthirus gorillae approximately 3.3 million years ago. It is more distantly related to the genus Pediculus, which contains the human head and body lice and lice that affect chimpanzees and bonobos.
