Neolinognathidae (order Phthiraptera, suborder Anoplura) Family of sucking lice which are parasitic on Macroscelidea (elephant shrews). The species in this family can be distinguished from all other lice by their possession of a single pair of abdominal spiracles, on segment 8 (most other lice have a pair of spiracles on each of segments 3 to 8, and those that have fewer than six pairs have lost those on segment 8). The family comprises a single genus, Neolinognathus, with two species.
