The type species of Rhonciscus is Pristipoma crocro which Fishbase still places 'within the genus Pomadasys.[3] Molecular studies now suggest that Pomadasyssensu 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. argenteus.[6]
