Rhonciscus is a genus of marine ray-finned fish, grunts belonging to the family Haemulidae.

The species within the genus are found in the eastern Pacific and western Atlantic Ocean.

[3] Molecular studies now suggest that Pomadasys sensu lato is paraphyletic with the Rhonciscus clade being Sister to the Haemulinae branch comprising the genera Haemulopsis, Conodon and Xenichthys.

[4] The genus Rhonciscus Jordan & Evermann, 1896 was revived to include the species listed above,[5] A third species, Pomadasys branickii, has also been suggested for inclusion in this genus.

[4] The name Pristipoma is unavailable as its type species is Lutjanus hasta, a junior synonym of P.
