- Description
- The Genus Dinoperca was erected by Boulenger (1895) for the Northern Indian Ocean species Hapalogenys petersi Day and assigned to the Family Serranidae. Boulenger (1903) described a second species, D. queketti, from South Africa. Most subsequent authors have accepted the placement of Dinoperca in the Serranidae, but Johnson (1983) removed it from the Serranidae to the taxonomic limbo of “Incertae sedis’’. Centrarchops Fowler (1923), with a single West African species, was originally assigned to the Serranidae and has been treated by subsequent authors in the Serranidae. The osteology, myology and the otolith (sagitta) of D. petersi reveal no characters that would relate Dinoperca to any particular family of percoids. Furthermore, the presence or absence of certain characters preclude Dinoperca and Centrarchops from the Family Serranidae, and the superfamilies Haemuloidea, Lutjanoidea and Sparoidea. Two features appear to be uniquely derived characters (synapomorphies) justifying a separate family for Dinoperca and Centrarchops: (1) Frontal bones bearing a high median crest that articulates posteriorly with the supraoccipital crest and is cleft dorsally by a narrow median sulcus extending ventrally to the roof of the brain cavity. (2) Large swim-bladder with three pairs of large intrinsic muscles., Rhodes University Libraries (Digitisation)
