Rhycherus

Rhycherus is a genus of marine ray-finned fishes belonging to the subfamily Histiophryninae in the family Antennariidae, the frogfishes. The fishes in this genus are endemic to the waters off Australia. This genus is classified in the monogeneric family Rhycheridae, the Balrog frogfishes, by some authorities.

==Taxonomy== Rhycherus was first proposed as a monospecific genus in 1907 by the Australian ichthyologist James Douglas Ogilby when he described Rhycherus wildii. R. wildii had its type locality given as South Australia, this taxon is now considered to be a junior synonym of Chironectes filamentosus, originally described by François-Louis Laporte, comte de Castelnau in 1872 from St Vincent Gulf in South Australia. Some authorities classify this genus in the subfamily Histiophryninae within the family Antennariidae, while others place it in the monotypic family Rhycheridae. However, the 5th edition of Fishes of the World does not recognise subfamilies within the Antennariidae, instead classifying the family, including this genus, within the suborder Antennarioidei and the order Lophiiformes, the anglerfishes.
