Similar Taxa

  • GeophilidaeBoth belong to Geophilomorpha and share elongated bodies with numerous segments; Himantariidae can be distinguished by the short with concave labral margin bearing denticles, specific mandibular structure (single dentate plus pectinate lamellae), and ultimate legs typically lacking pretarsus.
  • MecistocephalidaeAnother geophilomorph with high segment counts; Himantariidae differs in mandibular configuration and forcipular segment (stout with short forcipules and wide tergite).
