phthiriasis

Infestation of the eyelashes is referred to as pediculosis ciliaris or phthiriasis palpebrarum.

Infestations of crab lice are known as pediculosis pubis or phthiriasis pubis (which, unlike the generic name of the louse, is spelled with a phth).

Aristotle reported that it was believed Alcman died from a pustulant infestation of lice (phthiriasis), but he may have been mistaken for the philosopher Alcmaeon of Croton.

Infestation with pubic lice is also called phthiriasis or phthiriasis pubis, while infestation of eyelashes with pubic lice is called phthiriasis palpebrarum or pediculosis ciliarum.
