Grammatonotus

Grammatonotus is a genus of marine ray-finned fishes belonging to the family Callanthiidae, which includes the splendid perches and groppos. These fishes are found in the Indian and Pacific Ocean. All of the species in the genus are known in English as groppos.

==Taxonomy== Grammatonotus was first proposed as a monospecific genus in 1905 by the American ichthyologist Charles Henry Gilbert when he described the new species Grammatonotus laysanus, its type locality given as near Laysan Island in the Leeward Hawaiian Islands, which he also designated as the type species of the new genus. He also placed the genus in the family Serranidae while other workers classified it in the Grammatidae. In 1981 Pierre Fourmanoir erected the family Callanthiidae for this genus and Callanthias. The 5th edition of Fishes of the World classifies Grammatonotus as one of two genera in the family Callanthiidae, which it places in the order Spariformes.
