Systematics

The type species of Rhonciscus is Pristipoma crocro which Fishbase still places 'within the genus Pomadasys.^[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. argenteus.^[6]
