In addition to the Ecdyonurinae characteristics, the following combination of characteristics will identify the genus:

Larval Diagnosis

Larvae of Notacanthurus are easily identified by having a dorsal median abdominal ridge and well-developted gill lamellae (Fig. 18). Larvae of the Indian species N. edentatus Braasch do not have a well-developed dorsal ridge on the abdomen (Braasch, 1986), so they are similar to Electrogena but can be differentiated from by the absence of denticles on the claws.

Adult Diagnosis

Adults of Notacanthurus have a greatly expanded anterior margin of head capsule (Fig. 131), a characteristic not found in any other genus.
