- Commonly called as centipede.
- Body is elongated, dark greenish-brown in colour, dorsoventrally flattened and is divided into a distinct head and a long, segmented trunk or body.
- Head segments are closely fused. Head appendages are long antennae, ocelli and reduced maxillae and mandible visible on ventral side.

- Body segments have 21 pairs of walking legs. The first pair of legs are curved, clawed and forwardly directed to form maxillipedes or poison claws, while the rest of walking legs have 7 joints. All walking legs are similar.
- Each leg is composed of coxa, trochanter, femur, tibia and 3 tarsi ending in a single claw.
- Paired, oval spiracles or stigmata lie on the pleural areas, above the leg bases on segments 4,6,9,11,13,15,17,19 and 21.
- Last segment bears ventral anus, genital atrium and a pair of anal style.
- There is a single pair of tracheal tufts opening to the exterior on the head.
