Osteology and Myology of the Cephalic Region and Pectoral Girdle of Heptapterus mustelinus, Comparison With Other Heptapterins, and Discussion on the Synapomorphies and Phylogenetic Relationships of the Heptapterinae and the Pimelodidae (Teleostei: Siluriformes)

The cephalic and pectoral girdle structures of the heptapterin Hepapterus mustelinus (Nemuroglanis clade') are described and compared to those of two representatives of the other, more plesiomorphic, main heptapterin group, namely Goeldiella eques and Rhamdia guatemalensis ('basal clade�...
