Kyphosus is a genus of sea chubs native to the Atlantic, Indian and Pacific oceans.[4] It is the only genus in the subfamily Kyphosinae of the family Kyphosidae.[5]

There are currently 16 recognized species in this genus:

Kyphosus analogus (T. N. Gill, 1862) (Blue-bronze sea chub)
Kyphosus atlanticus K. Sakai & Nakabo, 2014 (Caribbean sea chub)[6]
Kyphosus azureus (O. P. Jenkins & Evermann, 1889) (Zebra-perch sea chub)
Kyphosus bigibbus Lacépède, 1801 (Brown chub)
Kyphosus bosquii (Lacépède, 1802) (Bermuda sea chub)[6]
Kyphosus cinerascens (Forsskål, 1775) (Blue sea chub)
Kyphosus cornelii (Whitley, 1944) (Western buffalo bream)
Kyphosus elegans (W. K. H. Peters, 1869) (Cortez sea chub)
Kyphosus gladius Knudsen & Clements, 2013 (Gladius sea chub)
Kyphosus hawaiiensis K. Sakai & Nakabo, 2004 (Hawaiian chub)
Kyphosus incisor (G. Cuvier, 1831) (Yellow sea chub)
Kyphosus ocyurus (D. S. Jordan & C. H. Gilbert, 1882) (Blue-striped chub)
Kyphosus pacificus K. Sakai & Nakabo, 2004 (Pacific chub)
Kyphosus sectatrix (Linnaeus, 1766) (Bermuda chub)
Kyphosus sydneyanus (Günther, 1886) (Silver drummer)
Kyphosus vaigiensis (Quoy & Gaimard, 1825) (Brassy chub)

Some of the above species have now been synonymised with others within the genus; K. analogus and K. incisor with K. viagiensis, K. atlanticus and K. pacificus with K. sectatrix while K. bosquii is synonymised with K. bigibbus.[7]
