The body of Thoracophelia spp. is divided into three distinct body regions: 1) an anterior cephalic region consisting of the prostomium and first two setigers; (2) a swollen thoracic region; and (3) a long narrow posterior region characterized by a ventral groove and branchiae. A transverse groove/lateral notopodial ridge separates the thoracic and posterior region (Santos et al., 2004).
