Paralabrax dewegeri, the vieja, vieja parrot rock-bass or meo viejo, is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae, classified as part of the family Serranidae which includes the groupers and anthias.

It is a carnivorous species which has a diet largely made up of crustaceans but it also feeds on fishes, molluscs, worms and brittle stars.

Females attain sexual maturity at about 11 centimetres (4.3 in) and this species is a protogynous hermaphrodite.

[5] It is the sister taxon to P. callaensis of the eastern Pacific Ocean and, in turn, these two species hare a common ancestor with the Galapagos endemic P.

[6] Paralabrax dewegeri is said to have palatable flesh but it is of little commercial importance to fisheries because of its relatively small size.
