Peterjohnsiidae is a small family of millipedes belonging to the order Chordeumatida.^[1] The family was first described in 1987 by Jean-Paul Mauriès.^[2]^[3] These millipedes range from 3 mm to 8 mm in length and are found in Australia.^[4] Species in this family exhibit sexual dimorphism in segment number: adult males have 30 segments, but adult females have 32 segments (counting the collum as the first segment and the telson as the last).^[5]^[3] In adult males in this family, the gonopod complex involves three leg pairs (pairs 8 through 10) rather than just the two (pairs 8 and 9) usually modified into gonopods in this order.^[6]
