Lophoproctidae is a family of millipedes in the order Polyxenida containing approximately 65 species in 6 genera.

[1] Lophoproctids are distinguished by a soft body, bearing bristles at the posterior end of each diplosegment;[2] they are blind and generally lack pigmentation.

Individuals are small, ranging in size from 1.2 to 4.2 mm.

[3] Adults have 13 pairs of legs with internal leg buds,[4] except for those in one species (Lophoturus madecassus), which have only 11 pairs of legs.
