(order Phthiraptera, suborder Amblycera)
Family of chewing lice which are parasitic on Caviidae and marsupials in S. America. Members of the family are distinguished from other Amblycera by the contraction of the first abdominal tergal plate, the reduction or absence of the first pleural plate, the loss of the spiracles on abdominal segment 8, and the presence of two tarsal claws on each leg (the last character being unusual in mammal lice). There are six genera, with 10 species.
