4-851: Siphunculata Sucking lice ( Anoplura , formerly known as Siphunculata ) have around 500 species and represent the smaller of the two traditional superfamilies of lice . As opposed to the paraphyletic chewing lice , which are now divided among three suborders , the sucking lice are monophyletic . The Anoplura are all blood-feeding ectoparasites of mammals . They only occur on about 20% of all placentalian mammal species, and are unknown from several orders of mammals ( Monotremata , Edentata , Pholidota , Chiroptera , Cetacea , Sirenia , and Proboscidea ). They can cause localized skin irritations and are vectors of several blood-borne diseases. Children appear particularly susceptible to attracting lice, possibly due to their fine hair. At least three species or subspecies of Anoplura are parasites of humans;

12-404: The human condition of being infested with sucking lice is called pediculosis . Pediculus humanus is divided into two subspecies, Pediculus humanus humanus , or the human body louse , sometimes nicknamed "the seam squirrel" for its habit of laying of eggs in the seams of clothing, and Pediculus humanus capitis , or the human head louse . Pthirus pubis (the human pubic louse ) is the cause of
