| Acumen terminating in upturned corneous spine and reaching just distal of midpoint of antennular peduncle. |
| Plumose setae and aesthetascs are present on the peduncle, and simple setae on the antennular flagellum were noted, from stage I larvae to adults. |
| The long antennular aesthetascs and the long plumose natatory setae of the first and second maxillipeds have been drawn truncated. |
| Behavioral and electrophysiological experiments suggest that the antennular outer flagellum is the site of pheromone reception in the male helmet crab Telmessus cheiragonus. |
| The peripheral and central antennular pathway of the Caribbean stomatopod crustacean Neogonodactylus oerstedii. |
| Although the clypeus and labrum of Reboursia exhibit a sphaeromatoid shape, it has a broad separation between the antennular basal articles. |
