The first segments which connect the appendages to the body are known as the coxa (plural coxae).
The arthropod hipleg joint consists of two parts the coxa (or the hip) and the trochanter (or the head of the arthropod leg femur).
He suffered especially from deformed hip joints (due either to hip dysplasia or coxa vara, with secondary osteoarthritis).
Each leg has seven segments which, from the prosoma out, are: coxa, trochanter, femur, patella, tibia, tarsus and pretarsus, and claw.
Certainly in their morphology they are not jointed, and so lack the five segments (coxa, trochanter, femur, tibia, tarsus) of thoracic insect legs.
The mesothorax and metathorax each have a pleural suture (mesopleural and metapleural sutures) that runs from the wing base to the coxa of the leg.
There are a few patches of light cyan on the coxa, the inner part of the femur and sometimes the head.
The inside of the coxa (or gnathobase) carries spins, probably to process prey items.
