A family of parasitic tongue worms (order Porocephalida, phylum Pentastomida) characterized by four hooks arranged in a curved line on either side of the mouth. Adults are found in the lungs of reptiles, and larvae or nymphs are found in the tissues of a great variety of vertebrates, including humans.
See also: Linguatulidae, Armillifer, Linguatula.

Two families, Linguatulidae and Porocephalidae of which two important genera Linguatula and Armillifer, respectively, have been known to be of importance in veterinary and human medicine [3].
The most recent phylogenetic systematization showed that the Class Pentastomida is divided into four orders (Cephalobaenida, Raillietiellida, Reighardiida, and Porocephalida), the latter with two superfamilies (Linguatuloidea and Porocephaloidea) and four families (Linguatulidae, Sub triquetridae, Sebekidae, and Porocephalidae; see Almeida and Christoffersen, 1999).
The family Porocephalidae is formed by seven genera, including Porocephalus.

The taxon Pentastomida comprises approximately 131 species distributed in seven families, namely Cephalobaenidae, Linguatulidae, Porocephalidae, Rallietiellidae, Reighardiidae, Sebekidae and Subtriquetridae (Almeida & Christoffersen, 1999), where they are preferentially pulmonary parasites of vertebrates, mainly reptiles (Almeida & Christoffersen, 2002).
Lizards are often and expectedly hosts to a variety of arthropods, including external mites (Leeuwenhoekiidae, Macronyssidae, Pterygosomatidae, Trombiculidae) or ticks (Argasidae, Ixodidae) and internal pentastomids (Cephalobaenidae, Porocephalidae, Sambonidae) (Wharton & Fuller 1952; Zumpt 1961; Yunker & Radovsky 1966; Hoogstraal & Aeschlimann 1982; Self 1982; Cruz 1984).
