| Both types of arthropods employ two short basal segments, coxa and trochanter, although the trochanter and femur are fused in some insects. |
| In one of the legs determine the coxa, trochanter, femur, tibia and tarsal segments. |
| Proxicarpilius exhibits the weak dorsal carapace ridge at the anterolateral corner and the direct articulation of the coxa with the merus, typical of carpiliids. |
| Thus in Tettigonia F. it is bilobed, and between it and the coxa two small pieces are inserted. |
| Flared iliac wings and shallow acetabulae are present along with coxa valga and flaring of the femoral metaphyses. |
| In entomostracan crustaceans, the occurrence of a coxa is restricted to exactly those appendages, the antenna and mandible. |
