Sucking louse

The tailed Old World monkeys (Cercopithecidae) support sucking lice of a distinct genus, Pedicinus which has certain similarities to Pediculus and has been placed by most authorities (though not by Ferris) in the Pediculidae.

Of the 200 or so species of sucking lice, only three infest man: the body louse, Pediculus humanus, the head louse, P. capitis and the pubic louse, Pthirus pubis (also known as the crab louse).

In fact, if, as claimed, the "love lice" don't consume blood, then they're not pubic lice, or any other kind of sucking lice, either, since all sucking lice require blood (not dead skin cells) to live.
