Belongs within: Eugnatha.
Contains: Neoatractosomatoidea, Anthroleucosomatidae, Cleidogonoidea, Diplomaragnidae, Conotylidae, Megalotylidae, Metopidiotrichinae.

The Chordeumatida are a group of relatively short, bristly millipedes.

Characters (from Hoffman 1990): Body with 26–30 segments in adults; ocelli usually present; gnathochilarium with short basal mentum and elongate lingual lamellae; ozopores absent; metaterga with well-defined median longitudinal suture; sterna not firmly attached to adjoining sternites but more or less flexibly articulated by connective tissue; males with coxal sacs in ninth and tenth pairs of legs only; gonopods composed of both pairs of legs of seventh segment.
