Specimens of the type species of the ascaridoid genus Iheringascaris Pereira, 1935, I. inquies (Linton, 1901) (Anisakidae), were collected from the digestive tract and mesentery of its type host Rachycentron canadum (Linnaeus) (Rachycentridae, Perciformes) from off the Atlantic coast of South Carolina, USA, during May of 2011. Scanning electron microscopical examination, used for the first time for specimens originating from the West Atlantic, made it possible to study in detail some taxonomically important morphological features, such as the number and distribution of male caudal papillae, cephalic and cuticular structures, deirids and cloacal (anal) lips. The allocation of other, poorly described, species from different hosts in Indian waters to this genus needs to be confirmed.
